Honestly, I kind of regret buying a fitbit last year. All the data has to be uploaded to their servers before I can view it, and the app periodically logs me out on my phone. Yes, the battery life is pretty long, but I could have lived without this device if I knew it was going to be like this ahead of time
@Gargron I use garmin. Itws great on battery (a week), is a pretty robust smartwatch in terms of app selection and watch faces, Waterproof so you can dive fairly deep while swimming, and has good analysis.
