🕑 Garmin — Coming Soon We're waiting for API approval.

The quick answer

Both brands speak athlete. But they speak different dialects. Polar is the heart rate specialist — the H10 chest strap is the gold standard for HRV accuracy, and their watches are purpose-built for training. Garmin is the data maximalist — covering all 14 signals including stress, Body Battery, SpO2, and body composition.

Note: Garmin integration is coming soon.

The signal gap

Polar delivers 8/14 signals and covers 9/10 MyBodyAI metrics. Garmin delivers 14/14 and covers all 10 at full accuracy. The six extra Garmin signals — stress, Body Battery, SpO2, weight, body fat, muscle mass — unlock our Stress Load index at full power and make biological age calculation significantly more accurate.

Poznámka: Integrace Garmin je na cestě.

Mezera v signálech

Polar dodává 8/14 signálů a pokrývá 9/10 metrik MyBodyAI. Garmin dodává 14/14 a pokrývá všech 10 na plnou přesnost. Šest extra signálů od Garmin — stres, Body Battery, SpO2, váha, tuk, svaly — odemykají index Stresová zátěž na plný výkon a výrazně zpřesní biologický věk.
