Hydrabit: Track your hydration intake on the iPhone and Apple Watch.

I found myself forgetting to drink throughout the day. I wanted to build an app that had no extra fluff. Just gentle reminders about hydration and the importance of taking small breaks throughout the day. It was also important to me that the app has no external connections; everything needs to be local. I've worked in digital analytics and advertising long enough to know about the risks of leaking data to third-parties, even if it's just "benign" app telemetry. I also wanted the app's UX to serve its singular purpose. I wanted to avoid achievement clutter, gamification, and similar. I did add some local data and stats, which I think are interesting to anyone who uses the app for a longer time. The app really benefits from an Apple Watch companion, because your hydration reminders can be handled on the watch independently of the phone app (sync will be done when the two are back in range).
