It is stuck and does nothing ### 5/5 — Battery App Is a must have App for Battery *2022-06-12, version 2.4* I really like the idea that we are all together and we are all set to learn about things that we can do for our future and we can always pray together for all of the people who have already done things for our lives and the other stuff that we will do ### 1/5 — Will not update *2022-05-21, version 2.4* I read some reviews saying they had to open the app to get the complication to update, but it will not update on my watch at all even after opening it. Making this useless. ### 1/5 — My Apple Watch just shows a question mark as the complication *2022-05-02, version 2.4* My Apple Watch just shows a question mark as the complication ### 5/5 — Review *2022-04-14, version 2.4* Great app ### 5/5 — Great App *2021-12-12, version 2.4* I love it lol ### 1/5 — Having issues. *2021-07-03, version 2.4* I just purchased this app to see my iPhone battery on Apple Watch. Unfortunately after installation and enabling notification, the app complications still can’t reach iPhone. I’m using the app on watch series 6 and iPhone 12 Pro Max. ### 1/5 — App doesn’t work *2021-05-28, version 2.4* App doesn’t work. Says my phone is unreachable. ### 1/5 — Doesn’t Work *2021-05-10, version 2.4* I have reached out to the developer letting them know that the devices don’t update. They responded letting me know I was wrong … and that it only reported what the native battery app showed I tried to explain that all the devices were on the iOS app but not on the watch app, and the watch app didn’t update anything more than the first 2 devices. Sad to say the developer responded once then stopped responding Once they knew the app they sell doesn’t work. Waste of money .. sorry I tried to support the developer with a purchase. Don’t buy this is you expect it to work. ## Frequently asked questions about Battery⁺ ### What does this app do?
