    Great app so far!

    Great app so far, still gathering data for accuracy. I’ll follow up later if it doesn’t live up to what’s advertised. Best battery features I have seen so far. Review follow up: It’s been almost 24 hrs since I started playing with the app. But I have yet to see any notifications. I first se it for 50% warning, nothing happened. So I tried for 20%, still no notice - it’s at 15% now, and I’m about to put it on the charger. I know an update is days away, keeping the faith. I like the UI overall. I’ll keep my current rate because I like the concept of what the app wants to do. I’ll re-rate the app if the notifications bug doesn’t improve.

    Has great potential but also an issue for me

    Works fine on my 44mm S4 but on my wife’s 40mm S4 I can’t add the complication to any watch face, using the My Watch iPhone app. I can, however, add the complication by editing the watch face directly on the watch. Tried the standard debug things, rebooting, uninstall/reinstall but to no avail.

    This is something I saw and knew I needed! I have always been worried about battery in short term and the long term this will help my watch. If there are more added features, it is a good buy.

Battery Grapher graphs your Apple Watch's historical battery levels and learns your habits to make smart predictions on what your future battery levels will be. Developed specifically with energy consumption in mind, Battery Grapher has almost no impact on battery life. 

Battery Grapher uses historical battery levels to intelligently predict what your battery level will be throughout the rest of the day, allowing you to plan when to next charge your watch. The longer you have Battery Grapher installed, the more accurate future battery level predictions will be.

Battery Grapher is made for people who want to extend the battery life of their Apple Watch, meaning that low energy usage is a priority. The app runs a background task only once an hour, and doesn't require an iPhone or internet connection, which keeps battery consumption extremely low.

Battery Grapher allows you to set notifications that fit your needs. You can  get the app to notify you when you battery drops below a preset percentage, or if you only have a certain number of hours left before your battery runs out.

Battery Grapher supports all complications available on the Apple Watch, giving you the flexibility to place your complication wherever you want.
