I have been using a Pebble Time Steel for years even after their acquisition by Garmin Someone corrected me it was FitBit not Garmin thanks to Rebble, a modded firmware that gives it new life, but I would like a smartwatch that can track my heart rate.
I don’t mind using an older device especially if it means a cheaper price. A bonus for me would be if it still had some kind of community around it or a custom firmware like Pebble watches do.
I found an original Moto 360 with a functional battery for about $30 but I am not sure if due its age its functionality would be greatly limited.
Edit: It seems like Garmin and FitBit might be worth looking at. But I wouldn’t know what devices to look at or if there have been any major improvements with recent revisions.
The Withings one is a good option if you want one that just looks like a normal watch.
Definitely withings. I have had a steel HR for 2,5 years now and I still love it. You can buy any standard wristband that you like and the battery lasts a month. It’s also waterproof so no worries there. Plus I like the more traditional look, so it still looks good when wearing a bit more formal clothes.
