Side-by-Side Comparison
| Spec | Google Fitbit Air (2026) | Amazfit Helio Strap (2025) |
|---|---|---|
| Price | $99.99 | $99.99 |
| Release Year | 2026 | 2025 |
| GPS | None — no GPS chip. Distance, pace and route come from the paired phone, so no phone means no route | None — no GPS chip. Outdoor workouts borrow the phone's GPS through the Zepp app |
| Display | None — screenless; there is no way to read a metric off the band itself | None — screenless; all data is read in the Zepp app |
| Rated Battery Life ( days) | 7 | 10✓ |
| What the Battery Claim Assumes | Google claims 'up to one week'. Continuous HR and SpO2 are on by default; there is no always-on display to switch off. Full charge ~90 minutes; a 5-minute top-up gives one day | Amazfit rates 10 days with continuous HR on; Tom's Guide got 12 days in review testing. Recharge takes under 2 hours |
| Subscription Model | Optional but the AI half is gated — Google Health Coach (adaptive plans, AI sleep-trend analysis) needs Google Health Premium. Heart rate, sleep stages, recovery guidance and women's health tracking are free. 3-month trial in the box | None. Every metric the strap produces is free forever — this is the device's entire pitch against WHOOP |
| Annual Subscription Cost ($) | 99.99 | 0✓ |
| Water Resistance | Not published in Google's launch materials — the bands are described only as 'sweatproof, wetproof silicone' | Amazfit markets it as sweat- and shower-safe; a formal ATM rating was not stated in the retail listings consulted |
| ECG / AFib & FDA Status | AFib alerts from the PPG sensor. No ECG electrodes, so no on-demand ECG at any price | No ECG hardware and no AFib detection |
| SpO2 Sensor | Yes — dedicated red and infrared SpO2 sensors | Yes — blood oxygen via the Zepp app |
| Phone Compatibility | iOS and Android | iOS and Android via the Zepp app |
| Charger | Proprietary magnetic contact charger — lose it and only Google sells the replacement | Proprietary magnetic charging clip |
| Data Export | Google Takeout export of the Google Health/Fitbit archive (JSON and CSV bundles) | Zepp syncs to Strava, Google Fit and Apple Health; Amazfit does not publish a documented bulk-export format |
| Warranty | 12 months | 12 months |
| Colors | Obsidian, Fog, Lavender, Berry | Black |
