Monitor your iPhone battery level from your wrist.

Juice Watch is a simple app designed to do two things well:

• Show the battery level of the paired iPhone in a complication on Apple Watch

• Deliver a notification on your iPhone when your Apple Watch is charging and gets above 90% (or whatever level you choose, from 50% to 100%)

Just glance at your wrist to monitor the charge of your iPhone throughout the day. Or, keep tabs on the battery level of your iPhone while it is plugged in and charging in another room.

You can see both your iPhone and Apple Watch battery levels on the same complication.

You can also get a notification on your Apple Watch when the paired iPhone is charging and reaches at least 80% (or whatever level you choose, from 50% to 100%).

You can set up low battery notifications, to get notifications when your Apple Watch or iPhone battery is low.

Juice Watch is available for a wide variety of complications, so you can use it on your favorite watch faces.

You can also use this app to check your Apple Watch battery level from your paired iPhone. This can be useful while your Apple Watch is charging somewhere else.

Keep in mind that the iPhone battery level shown on Apple Watch is not real-time. It is refreshed periodically, about every 5–60 minutes. The Apple Watch battery level shown on the paired iPhone refreshes at approximately the same rate.

Truly Unique Battery Data App!

I wanted to put out an update on this unique app! I have been using this app for some time now every day every hour and yes every second! Why because this app is truly a 5 star app!!!! The Developer did something on this app that had me scratching my head wondering why He did it that way? I sat down in a chair and thought to myself the Developers made a mistake other apps I tried did it another way! I got up and started walking around again thinking should I email the developer and tell him I think he is wrong? While walking I thought no He has a reason why He went this way. I looked at my Watch and it hit me why and I had to smile the Developer was really smart on that unique design in the app and yes the Developer almost had me making a fool of myself if I had not thought it out first? What was it? Download the app find out for yourself you will not be sorry!!! (Really) The Developer has been putting a lot of effort,time, and hard work in making the app better and better and better! I didn’t think it was possible that He could make a any better! But once again the Developer has proved me wrong. I truly truly thank the Developer for putting out such a great unique app! A 5 star design that works great but unique in the way He does it! Please for yourself download this app it’s really that nice and unique!! Thanks to the Developer for putting this app out for all of us to use! I truly bow down to you and give you my Thanks!!!!

Does what it needs to, and does it well.

I love that I can have my watch and phone battery statuses as one complication. The small battery indicator on iPhone makes me think I have more charge than I do, so seeing the percentage whenever I glance at my watch is great. I do wish that I could display the watch percentage next to the color bar (you can choose to display the watch percent, but the phone percent will be replaced with the bar instead).

The thing I loved most was that it is simple, works great, and not a single ad. Just a simple way to tip the developer at the bottom of the app, which I feel a tip is deserved for delivering a functional and great app.

Thanks so much for the kind words about the app and that suggestion about adding the number next to the gauge! I added that option in a new update that came out today.

Does not work

After installing this app on my phone and watch, I received a fully charged alert once my watch reached 98%. However, after receiving this first notification immediately after installing the app, Juice Watch has failed to work correctly. When I charge my watch to full battery, no notifications appear. The only way I’ve found to get the notifications to trigger is to open the Juice Watch app on both my watch and phone at the same time. Once I do that, all of the sudden Juice Watch realizes that the watch’s battery is full and sends the notification. But at that point the notification is useless because I have to observe that my watch is at full battery prior to opening the Juice Watch app in order to fire the notification. To troubleshoot, I put Juice Watch into the Favorites Dock on my watch as well as the complication on the active watch face, but this had no effect.

Bottom line: Juice Watch does not send fully charged notifications unless the app is open on both the watch and the phone.

That is not normal behavior, and the app is working fine for many happy users. Please read the User Guide: Tips & Tricks section of the app for suggestions to get it working, or contact me directly at if you need additional help.
