What the heck did you do?

I LOVED this app as a complication in my Apple Watch and iPhone. Then you did some kind of update and it completely stopped working on my watch. It works on the phone only now.

Thanks!

Many thanks to the developer of Battery Life app for updating and taking care of the app. I believe there are many people out there like me who appreciate your work.

Cool idea doesn’t work well

So I paid for the add free version and it was a reasonable price. I love the idea of adding my phone battery to a watch face. The problem is it doesn’t monitor the levels well. My watch was actually on 80 and the app that is on my watch is still reading 84. Worse for the phone battery. It was reading 100 percent still and the phone was actually on 84 percent. So yeah, if it worked awesome. But it doesn’t. Also I had the app open in the background, background app refresh and all that on, so it’s not that.

通知は一切来ません。

アプリ側の通知も全てオン、設定済み。iPhone側の設定でもバックグラウンド、通知、共にオンにしているにも関わらず肝心の通知が一回も届きません。AppleWatchの通知目的で有料で300円払ったのも払い損!詐欺だよ、これ。

Complications Numbers and Notifications Issues

Numbers shown on the watch complication are not always up to date on the watch face unless you tap it to open the watch app. Maybe they could better explain how the app works and what to reasonably expect.
Also I haven’t gotten but a single notification so far on my iPhone and none on the watch.
