What's new in MyBodyAI. Click any version to see what changed.
v0.997 beta
Latest
July 5, 2026
New
- A clinical sleep view: your night broken into light, deep and REM sleep in an animated donut, how long you took to fall asleep, and a multi-night trend so you can watch the shape of your sleep change over time.
- Load and Recovery on the Overview now shows the recovery score your device works out on its own (Polar, Oura, Whoop, Suunto) right next to MyBodyAI's own reading, so you can compare the two side by side.
- Fitbit Active Zone Minutes now appear on the Activities tab.
- Local weather and air quality: with your location, MyBodyAI now shows the current weather, ozone and UV index where you are, and shifts the suggested outdoor training time away from heat and poor air. Allow your location in one tap on the Overview, or set a city in Settings; your timezone is set from it automatically.
- Two-factor authentication: protect your sign-in with a passkey (your fingerprint or face), an authenticator app, or one-time recovery codes. It is optional but recommended for health data. You also get an alert when a new device signs in, plus trusted-device management.
- Oura Ring support: connect your Oura over secure OAuth for sleep, heart rate and HRV, blood oxygen, breathing rate, skin temperature and daily activity.
Improved
- A thorough mobile pass across the whole app: notch and safe-area support, bigger tap targets, an offline banner, add-to-home-screen, smoother loading with content skeletons, and fixes to anything that ran off the edge on narrow phones.
- The energy map opens fullscreen, including landscape on phones, and you can edit your day's windows by dragging them, with 15-minute nudges; your plan saves instantly.
- Weather is easier to set up and more accurate: one-tap GPS with your place name, a manual city option, and the forecast now follows the Yesterday / Today / Tomorrow switch on the Overview.
- Illness Risk is now called Body Alert, without pseudo-probability percentages, to describe what it really is: a heads-up from your own signals, not a medical prediction.
- Withings vascular age and visceral fat are now surfaced across more of the app (Overview, Health, Activities and Progress), with honest measured-versus-estimate labelling and a what-if biological-age simulator.
- aiclysm.com refreshed: a data and security section on the homepage, Oura added to the supported-device lineup, and a new brand-first hub to compare all devices.
Fixed
- Trends now labels 'lower is better' signals the right way, and cards with no data for the chosen period hide themselves instead of showing blanks.
- Biological-age domains now display and rank correctly as ages, where younger is better.
v0.996 beta
June 21, 2026
New
- Polar now delivers full daily activity: steps, calories, active minutes and daily minimum and maximum heart rate join the sleep, heart rate and HRV Polar already provided, so Polar users see the same activity and load picture as Garmin and Fitbit users, and their load and recovery scores use it
Improved
- VO2max from your watch now counts toward Biological Age: the fitness domain (the strongest single longevity signal) reads your Garmin, Fitbit or Polar VO2max instead of only a manually typed value
- Key Signals on the Overview redesigned: a 7 / 14 / 30-day period switch, mini trend lines with today marked, and a clear five-level colour verdict for each signal
- A short or sleepless night now steers the day toward rest: readiness is held back and sleep debt is counted instead of being hidden by an older recovery reading, and the day's guidance now reads the same across the banner, the hero and the cards
- Watch comparison pages on aiclysm.com refreshed with an editorial layout and corrected device-capability data
v0.995 beta
June 9, 2026
New
- Redesigned dashboard: seven focused tabs (Overview, Trends, Health, Performance, Activities, Sleep and Progress) with your Body Status figure as the home hero, a sidebar and a calendar on every tab
- Daily coach on the Overview names your body's state in plain words and tells you whether today is for training, adapting or resting
- Energy map: see how your energy rises and falls through the day, find the best window to train or focus, edit your day plan and test a what-if before you pick a bedtime or a workout
- Performance tab: fitness, fatigue and form on one curve built from your training load, an intensity split and a 90-day adaptation view
- Body load map on Activities shows which parts of your body took the most from recent training, with the intensity and the session behind it
- Health tab in depth: a body-system view, biological age with its trend, and now vascular age, visceral fat and blood-pressure ranges from your Withings
- Progress tab: a living avatar, daily rings, simple missions and a long-term journey that rewards consistency
- Day rhythm editor: set your work, training and sleep windows, and the recommended bedtime is learned from your own wake times
- Share your dashboard as an image with one tap, and revisit any past day from the calendar
Improved
- The Overview is now a decision layer, not a copy of the detail tabs: one screen for what is happening today, why, and what to do next
- Honest empty states across the app: when there is not enough data yet, the app says so instead of showing a made-up value
- The legacy Mindset dashboard has been retired; its full set of charts lives on as a dedicated All graphs page
v0.991 beta
May 16, 2026
New
- AI Hub — the AI tab is renamed and restructured into three layers (Today / What is happening / Bigger picture) with a Next-days Outlook section and an Open Insight CTA
- 10-band decile metric system — all 13 health metrics now use a single 10-band copy table (severity + insight + AI tip in EN and CS) instead of the old 3–5 tier ladder, so every score position has a tailored interpretation
- Body Status hero rework on the dashboard — gauge size roughly doubled and the competing person silhouette removed, so the headline number reads as the visual anchor
- Weekly digest redesigned — week-over-week comparison hero with gauge bar, four delta tiles, 7-day bar chart, top three highlights and a recommendation. Delivered Monday 10:00 Europe/Prague (was Sunday 8 UTC)
- Confidence chip on dashboard tiles — when the underlying confidence drops below 0.8 the chip appears (yellow under 0.8, red under 0.5), so a glance at a tile reads as value, trend, confidence
- Provider tier badge per signal on /connect — a gold / silver / bronze dot next to each signal shows which provider is the trusted source (Fitbit VO2max gold vs Fitbit steps bronze, etc.), no more uniform colour per provider
- Five topic-cluster hub pages on aiclysm.com — HRV, Sleep, Recovery, Longevity and Stress — each cross-linking around ten articles, glossary entries, tools and device comparisons
- New blog post — HRV accuracy compared across Garmin, Polar, Fitbit and Withings, bilingual, with eight peer-reviewed citations
- /.well-known/security.txt — coordinated disclosure contact per RFC 9116 for security researchers
- Activities now show additional details — speed, power, elevation gain, moving time, minimum heart rate and step count alongside duration, distance and load — pulled from Garmin or Strava and merged on a per-field basis
- Bilingual confirmation email after a successful Garmin GDPR import — summarises what landed (HRV, SpO2, VO2max, activities) and suggests a complementary provider when something is missing
Improved
- Morning Energy recalibrated — HRV switched to an absolute mapping (was personal percentile), weights tuned to 0.2 HRV / 0.5 sleep / 0.3 RHR after grid search, plus 10-band insight copy and driver chips (Sleep Quality / ANS Balance / Sleep Debt)
- Sleep debt is now shown with sign in hours across all UI — −X.Xh debt / +X.Xh reserve — instead of a 0–100 score that hid the direction
- AI tips audit — seven logic and copy bugs fixed across micro-tips, training tips, AI insights, alerts, daily narrative, weekly digest and the adaptive engine
- Flagship cards rewritten in semi-lay tonality — drops ‘sympathetic’ / ‘vagal’ / ‘autonomic’ / ‘baseline’ jargon in favour of stress response, balance, recovery system
- Transactional emails visually overhauled (all 11 templates) plus a dark-mode override for new Outlook for Windows / Outlook.com / Gmail / Apple Mail — the deep-navy palette is no longer repainted to mid-gray
- Light mode redesigned — warm cream-sand palette unified across marketing and dashboard, plus a hairline outline on the Body Status hero so colours stay legible on the lighter background
- Typography refresh — Manrope across body and display headings (JetBrains Mono kept for code), marketing homepage emoji icons replaced with Lucide SVG (seven stroke icons matching the brand line)
- Dashboard typography pass — hero gauge resized, signature ring slimmed and the Bio Age font capped at one consistent size across all tabs so the headline numbers stay the visual anchor on phone screens
- Glossary entries, blog posts and topic hubs now cross-link automatically — about 190 inline references added in EN and CS so reading an HRV article surfaces the matching glossary entries and related posts in one click
Fixed
- Morning Energy proxy never reached non-Garmin users in the live pipeline — an old guard counted Garmin-specific history days and dropped the proxy context for everyone else. Re-filled 549 historical rows for 11 affected users
- Bio Age card now stays interactive when birth date is missing — clicking the empty-delta state routes you straight to Settings → Profile → date of birth
- Garmin GDPR import auto-fills bio-age inputs (gender, birth date, height, weight, VO2max) from user_profile.json and BioMetricProfileData inside the export ZIP
- Garmin GDPR activities are now imported and merged with existing Strava records — Garmin contributes training load, training effect and VO2max to the same activity row, the richer source wins per field
- Profile save now invalidates AI and scoring caches — previously the dashboard returned 6h stale data right after you filled in birth date and gender
- Tools pages (biological-age, hrv-decoder, sleep-calculator) no longer hit an infinite reload loop when localStorage.lang differs from the URL language
- Mobile Chrome auto-translate no longer crashes the app — a notranslate meta hint prevents the browser from wrapping text nodes, which used to desync React on the Settings page
- Czech URL prefix /cs/ now wins over the localStorage language setting — sharing a CS link with someone whose browser is set to English no longer flips the page to English
- Strava and Garmin webhooks are now correctly proxied through Caddy to the wearables backend — previously these events 404ed and were silently dropped
Security & Infra
- Mobile auth token sliding expiry — every successful X-Mobile-Token auth refreshes the token timestamp (throttled to once per 24h), so a daily-worn paired Garmin watch keeps a live token indefinitely while a 90-day idle device still expires
- PostgreSQL timestamps now native — 16 columns migrated from TEXT to timestamptz, dropping the ::timestamptz casts on every indexed read across admin, auth cooldowns and premium expiry
- Major dependency bumps — Stripe SDK 14.4.1 to 15.1.0, gunicorn 25.1.0 to 26.0.0, sentry-sdk 2.29.1 to 2.59.0, postcss 8.5.8 to 8.5.14, vite 7.3.1 to 7.3.3 (4 npm advisories closed)
v0.99 beta
May 4, 2026
New
- Backdate self-report up to 7 days — day picker chips (Today / Yesterday / weekday) so you can fill in a missed check-in for any of the last week
- Garmin Connect IQ watch app (Pre Release) — on-watch health dashboard for 67 supported devices (Fenix, Forerunner, Venu, Epix, Vivoactive, Enduro, Instinct), pair via 6-digit code in Settings
- Garmin GDPR import now extracts HRV, SpO2, VO2max and AFib events from FIT files inside the export ZIP — massive jump in Garmin data coverage
- Garmin Index Smart Scale support — weight, body fat %, muscle mass, bone mass, body water % imported from your GDPR ZIP and shown on the Body card
- Both signature slots (left + right) are now user-configurable — pick from 14 metrics for each side, persisted across tabs and devices
- One-click Disconnect button on /connect page for any OAuth provider (Fitbit, Polar, Withings, Strava) — revokes tokens server-side, stops dormant alerts
- FAQ Connection issues category — 10 bilingual entries covering re-OAuth, dormant providers, missing data and pairing problems
- Illness Risk model adds breath-rise trend (Mason 2022) — rising overnight respiration is a documented early-warning signal for infection
Improved
- Bio Age card always renders, even when chronological-age delta is missing — you still see the radar with all 8 domains and contributing top three
- Insight detail popover is now inline — opens above the metric instead of a full-screen modal, with proper scroll and responsive grid
- Dormant provider banner now distinguishes ‘no device paired’ from ‘scope upgrade needed’ from ‘sync stalled’ — targeted action for each
- Apple Health removed from the UI everywhere — the provider was retired upstream and listing it caused user confusion
- Settings page exposes a Watch Pairing card — generate a 6-digit code with a 5-minute countdown, copy button, and clear instructions for Garmin Connect Mobile
Fixed
- Health tab Training Load chart now populates — the score was being computed but never plumbed into the history payload, leaving the sparkline empty
- Re-connecting an expired or revoked provider actually reactivates it — previously the new tokens were saved but the status stayed ‘expired’, leaving the device invisible
- Watch pairing endpoint no longer rejects every request as forbidden — CSRF guard correctly skipped on the pre-session pair exchange
- Backdating an existing self-report no longer leaves an orphan illness signature when you un-check ‘currently sick’ — routes through the proper edit pipeline
- Lockout ‘try again in N seconds’ banner now uses the actual cooldown window from the database, not a hard-coded value
- Bio Age calibration label dropped a spurious ×100 multiplier that made small adjustments look like 1500 % drift
- Polar 404 noise silenced for users without a Polar device — previously every sync logged 2,400+ false errors per day
- Self-report alcohol values 2 (moderate) and 3 (heavy) are persisted — previously the POST endpoint capped at 0/1 and silently dropped higher values
Security & Infra
- Admin panel hardening sweep — XSS escaping on log search results, RBAC self-protection (admins can’t demote themselves to a 401), persistent admin audit log with viewer, async transactional email
- OAuth tokens encrypted at rest — provider access & refresh tokens are now Fernet-wrapped in the database, dual-write phase complete with 21/21 connections backfilled
- P0 audit sweep — CSRF protection extended to every state-changing non-admin endpoint with documented exemptions, OAuth log sanitisation, contract drift guards, webhook HMAC hardening
v0.98 beta
April 20, 2026
New
- Daily Narrative — your day told as a coach's story with today's slogan, yesterday's recap, 7-day trend, and tomorrow's outlook
- 10-tier color scale across week trend bars — instantly see critical, steady, strong, or peak days
- Training Load metric + Strain context — tracks your weekly training stress with 7-day strain history
- Unlock panel — shows exactly which metrics become available when you connect another device
- Garmin data import via official GDPR export (ZIP upload) — while we wait for Garmin Connect API access
- Signal status on every metric — active, limited, stale, or unavailable, always clear why
- Community card in Settings — join our growing user community
- Illness Risk — redesigned as an AI 'defense shield' tile with an animated ring, breathing halo, live monitoring pulse, contributing biomarker chips (Immune, Respiratory, Recovery) and an adaptive insight that speaks to your current state.
- Biological Age — a paired 'youth gauge' visual next to Illness Risk with its own ring, breathing halo, top three contributing domains (e.g. cardiovascular, sleep, recovery) and age delta front and centre.
- AI Discoveries redesigned — correlation and seasonal patterns now render as premium cards with strength bands, metric-pair icons, and a four-season best-vs-worst strip.
- Tap any metric to see a detailed explanation — what it means, how we compute it, what influences it, and how to read the score. Fully translated to Czech and English.
Improved
- Plain-language score labels and mobile-friendly collapsible panels throughout the dashboard
- Natural, native Czech translations across all AI-generated daily insights
- Body Status now requires at least 5 core metrics before reporting 'Steady' — no more false 'all good' when data is missing
- Sleep efficiency now follows the AASM clinical standard (Total Sleep Time / Time In Bed) — consistent with sleep medicine research
- Self-reported symptoms now provide informational insight alongside biometrics instead of overriding scores — more transparent
- Faster login — last activity update moved off the critical path
- Better experience for Fitbit-only and scale-only users — sparse data handled gracefully
- Weekly Summary card now compares scores week-over-week with trend labels
- Dashboard layout reworked — your flagship metrics surface at the top, weekly trends moved below so the most actionable insight stays on screen first
- Hero consolidated — one unified Body Status gauge with a compact Training Readiness chip, replacing two competing indicators
- Changelog page redesigned — each version is now a one-click accordion so it's easy to scan the full release history
- Risk-type metrics (Illness Risk, Stress Load, Overtraining) now show raw values — a low number means a good state, with a short matching bar. No more mental math of 'is 94 good or bad?'.
Fixed
- VO2max badge restored on metric card
- Strain Chip labels now properly translated to Czech
- Mind / Body / Sleep panels no longer disappear after being opened
- Training Readiness card restored to hero section
- Garmin morning Body Battery now correctly uses peak 24h value
- Quick Tips icons (wind, check) display correctly
- Dark mode: below-threshold bars are now visible

- Withings workouts sync — fixed a date-parsing error that prevented workouts from syncing for every Withings user.
v0.97 beta
April 10, 2026
Improved

- Health data distribution models now correctly include all valid measurements
- Dashboard sync indicator no longer blocks header controls
- Security hardening and infrastructure improvements
v0.96 beta
April 7, 2026
Improved
- Sleep Quality score now reflects individual nights — a bad night drops your score immediately instead of being hidden by weekly averaging
- Sleep Quality now uses 6 signals (provider score, sleep phases, duration, efficiency, overnight recharge, trend) instead of a single average
- Circadian rhythm scoring recalibrated — deep sleep consistency no longer penalizes normal night-to-night variation
- Training recommendations now precisely match your readiness zone — no more intense workout suggestions on moderate-readiness days
- Trend explanations now correctly identify the driving signal for each health index change
Fixed
- Deep sleep values under 5 minutes are now filtered out (sensor misclassification)
- Illness risk adjustments from morning energy patterns are now visible in score diagnostics
- Historical scores recalculated to match updated algorithms — no artificial jumps in trend charts
