Always shows charging when it’s not. ### 2/5 — Started Great. Dead now. *2025-05-03, version 4.7* Not sure why, but this app no longer works on the watch face itself. Inside the app with the app details, the battery lives show working. ### 3/5 — Notifications *2024-10-26, version 4.6* Why is the app now notifying constantly when the watch is at 100%? ### 4/5 — Much needed update! *2024-09-23, version 4.4* Thanks for the long waited update, much nicer display, thank you, still slightly inaccurate by 1-2 % but no major deal. ### 3/5 — Hit or miss complication updates *2024-04-09, version 4.3* Watch app gets stuck “Contacting…” ### 3/5 — Did work well *2023-10-03, version 4.3* Did work ok, I’ve been using this application since it was released but the battery levels do not match what is on the phone in iOS 17 and watch iOS 10 ### 1/5 — Only works 1/3 of the time *2023-09-14, version 4.3* iOS 14 ### 3/5 — Needs New Feature *2023-09-03, version 4.3* I would very much like to see some new features added to this app Firstly this app needs to have a configurable maximum charge notification, this is because to maintain the health of your iPhone or Apple Watch battery it is advised not to overcharge it. Your iPhone or Apple Watch should not be charged to more than 80% of its maximum capacity. There is NO way to get a notification that your iPhone or Apple Watch has reached that charge level. Please update your app and give us the option to set a configurable maximum charge notification. ### 2/5 — Nice concept but useless *2023-09-02, version 4.3* I love the simple interface and the concept. However, the app info is never correct. My phone will only update when I open the app on my phone. Incredibly inconvenient and defeats the purpose of the app if I have to unplug it to get the info I need. By the time I put it back on the charger, the info is incorrect again. Also doesn’t alert me when my battery is 100% charged. Guess I’ll stick with default Apple notifications. ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken Sadly *2026-05-30, version 5.6* Used to be very useful for at a glance percentage telling but now stat updates never occur unless triggered manually making the feature fairly useless. ### 1/5 — Broken Again *2026-04-28, version 5.6* Used to be great now it’s not working at all!!! Please fix it. ### 1/5 — Never updates battery info *2026-03-27, version 5.6* The only time it updates is when i tap the complication on my watch. Then it won’t change all day after that. ### 1/5 — Pointless *2026-03-06, version 5.6* What is the point of this? Giving it a star is an insult to rubbish apps. It doesn’t automatically update. It has to be the worst app I’ve downloaded. The information has to be manually updated. I have to ask what was this developed for? Was it to tell you your caffeine intake or just an advertisement platform? If it is an advertisement platform don’t buy anything from it. Why because they must be desperate to advertise on a non functional pile of garbage. Actually it’s so bad that describing it as a pile of garbage denigrates how important and useful a pile of garbage is. So please tell me what is the point of this piece of trash? ### 1/5 — No longer works *2026-02-25, version 5.6* No longer gives correct information of the watch it says 40% when watch is 99% ### 1/5 — Doesn’t work *2026-02-24, version 5.6* Doesn’t alert me when my phone or watch or low. ### 1/5 — Don’t work on Apple Watch *2026-01-31, version 5.5* I got this app because of my Apple Watch 9. It showed 30% when I downloaded the app and after 3 days it hasn’t changed. Useless! ### 1/5 — Stopped *2025-12-06, version 5.5* The app has stopped working on Apple Watch 11 ### 1/5 — Doesn’t work at all *2024-09-24, version 4.4* None of the notifications work. Doesn’t update with watch battery status. Pointless. ### 1/5 — Broke with iOS 17 *2023-09-23, version 4.3* This app used to be perfect; the complication on my watch showed me the battery state for both my watch and phone at a glance. However, since upgrading to iOS 17 (or perhaps it was watchOS 10) it has stopped working on the Watch. The complication, still appears, but, it just hangs trying to update. ## Most praised reviews (10 highest-rated) ### 5/5 — Crashes on phone *2026-03-13, version 5.6* Can’t make it work anymore. When I open the Watch app it’s blank, and when I push the update button it crashes the phone app 😔 ### 5/5 — Easy information on where your battery is. *2026-02-20, version 5.6* Being using more than 5 years and terrific at displaying both watch & phone battery info. Really useful. ### 5/5 — Works well *2026-01-30, version 5.5* I’m been using this application since it was released. It’s a shame that apple restricts the level updates to 5% increments. ### 5/5 — Does what it says! *2025-08-23, version 4.8* Ignore the negative reviews. This is a completely free app, minimal ads, and does exactly what it says it will - allowing you to view Apple Watch and iPhone battery status on your watch face. So few apps are like this now - most either plaster ads or constantly ask for money like panhandlers. 10/10 ### 5/5 — Works well *2025-07-11, version 4.8* One of the first app I install whenever I upgrade my Apple Watch. My only feedback is localization. We have percentage icon first and number after here in turkey. An option to switch it to icon first and number later would be great. Like %70 not 70% ### 5/5 — nice app *2025-06-13, version 4.7* 功能很实在，电量的更新也较为及时，不需要干预就可以了解手机和手表的电量，唯一需要吐槽的地方在于软件的ui，希望开发者可以花点功夫优化一下表盘的外观，我会发邮件给你一些别的app的参考，很期待下载了这个app并一直使用的用户在看到新表盘时能感受到惊喜X:D ### 5/5 — The best battery app I’ve ever used *2025-05-29, version 4.7* Over the years, I’ve tried many battery apps—both free and paid—and this one is by far the best. I usually keep my battery between 40% and 80%, but if I’m going to be out all day, I charge it to 100%. This app will definitely help extend your battery’s lifespan. ### 5/5 — smart stick *2024-12-23, version 4.6* Please add a "smart stick" when rotating the digital crown, the battery interface appears as a mini widget! ### 5/5 — Complications great! *2024-09-27, version 4.5* The app is simple to setup and has various watch complication shapes for your supported Apple Watch face. You can setup the update frequency or tap on the complication to update power level meters for your watch and phone. I use it daily to easily see my power levels and if I need to charge my watch or phone soon. ### 5/5 — ⚠️ Feature request! *2023-04-13, version 4.1* Feature request: Notification when unplugged from charging. I need the above feature for my Apple Watch when charging with my powerbank while traveling. My powerbank automatically disconnects it once it’s 50% full. I want to know and turn on the powerbank again to charge it fully. Love the app! ♥️ Keep up the great working you’re doing. Update: I bought a new adapter to charge my Apple Watch. 1. Make the automatic update interval customizable. 2. Add Siri Shortcuts integration, to be able to ask Siri from the watch about the battery level of my iPhone. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
