I actually find the Apple Watch prompts to get off my arse if I haven't stood up in the last hour to be really quite useful. I'm sure there are cheaper ways.
All things considered, my Apple Watch has had the highest ROI of any piece of fitness gear I’ve ever bought. It finally integrated fitness into my life as a daily habit — I find myself actively wanting to run to improve my times and keep workout streaks alive. Gamification is pretty stupid for a lot of use cases, but really motivating for something like working out.
