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 notifications 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 choose to see the battery level for iPhone and Apple Watch on the same complication.

You can also 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.

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.

More accurate with complication

Just wanted to leave a review letting anyone looking know that this app is much more accurate when you have a complication for the app on your watch face. There are limits built into iOS/watchOS for how often apps can update in the background, and the update cycle comes around to an app much more often when it’s on your watch face.

I’ve never had the app be more than 3-5% off when the complication is used.

Thanks so much for this nice review, and thank you for explaining this!
