Withings smart watches are kind of insane with 30 day battery life, but the subscription farming in the app is infuriating.
All I want from a smart watch:
- Waterproof, wireless charging, at least a week of battery life
- Automatically track exercise and sleep, let me update the data if needed.
- Track my fitness trends over time, looking at you resting heart rate
- Optionally, learn a couple of recurring patterns to improve automatic exercise assignment. If I hike twice a week and you see an exercise session with a consistent heart rate profile you better believe I am hiking
Not just subscription farming, you cannot use the latest mobile app versions without agreeing to data mining. Their business model now is literally collecting user health and usage data to resell to other companies and of course for AI training. Avoid.
Garmin are pretty decent. I have an Enduro 2 which lasts a fortnight on a charge (currently 37% with 6 days of charge left).
It's waterproof. Unfortunately no wireless charging (proprietary cable) but it charges 2 weeks worth in about 2 hours.
It doesn't automatically track exercise, but it does collect a lot more (and higher quality) data than Withings for activity. Automatic sleep. The app has the trends and such, and there's no subscription (they recently added some AI stuff you can pay for but which is optional).
