I’ve used this app for about three years, and it’s always done exactly what I needed. I wanted an app that would show me my iPhone and Watch battery levels in one small complication on my Watch, and this was the only I could find. In a tiny amount of space, it shows the readings for both. It also lets you set custom notifications for battery levels of your choice, other than the 10% and 20% built in for the iPhone. For instance, I like to have a notification at 30% so I have more flexibility in when I charge it. In three years, I only had one minor problem (getting two notifications instead of one). I got an immediate reply from them, and a week later they released a new version that fixed the problem. Highly recommended.

Best option for watching your iPhone battery life from your Apple Watch!!!! Bidirectional communication allows you to check on your iPhone’s battery from your Watch and your Watch battery from your iPhone. The battery level of your iPhone is updated every 30 minuets on your Apple Watch to reduce battery drain on both devices!!!!

I’ve no idea if the app actually does what it promises — it’s so in your face about subscribing(!) that I was pelted with two ads and then two solicitations to upgrade the app (to remove ads) before I could even make my way around the app. Why does a battery status indicator app require a monthly or WEEKLY subscription? I can’t even imagine, but it’s bad actors like this that have turned everyone against legitimate subscription-based apps. And shoving the offer right up my eyeballs the first time I even glance at the app ... get out of here. Even if you offered a one-time payment option, you lost me completely with that garbage. Anyway, I deleted it in less time than it took me to review it. Just pick up your other device and look at it to check its battery life I guess.

I added the remotebattery complication to my apple watch but it just shows a question mark where the percentage should be. If you click it it opens the app to a page that shows the battery level of your phone and watch, but I got the app specifically so I could know my battery level at a glance, not by clicking and opening the app. It’s a shame but I had to download a different battery watch app that shows the percentage in the complication. Total shame because I liked the look of this one a lot, too bad it doesn’t work the way it’s advertised. I’m giving it 2 stars for just being a good idea.
