Wasn’t very accurate
I just wanted to be notified when my watch charged to a certain percent, but hadn’t realised that you have to have the complication on your watch face to do this. Even then, the complication showed 85% when the watch was at 83%.. I didn’t trust it.
Wish to update
It's a lovely app, but it hasn't seen an update since 2025. Hoping the dev adds new features soon!
Was Free
I downloaded this a couple days ago because I was always forgetting to charge my watch before I went to bed. It worked fine when I got to the percentage. I told my wife she should try it and now it’s showing $6.99. Not sure if I would have ever paid that much for a simple app.
Not working very well lately
It seems like the complication on my Watch does not update at all anymore for my watch or my iPhone. I have rebooted both devices numerous times and often times the complication does not update for my phone for 8 to 10 hours. This is not the way the app used to work so I am not sure if Apple fiddled with something in iOS 26 or if the app is taking a step backwards.

Please try deleting the app and installing it again. You can also always contact me through the app for troubleshooting help. I want to make sure it is working well for you!
Great but…
Exactly what I was looking for. Just one issue, the notifications sounds do not seem to work. I don’t know yet for the written ones.
Fonctionne très bien
L'app envoie la notification lorsque que ma Apple Watch est chargé à 80% . C’est exactement ce dont j’avais besoin!
Great Addition
Been using this since it was first available - and paid for it. Wouldn’t be without it now so it’s on all my watch faces.
Developer keeps it up to date. Highly recommended

Appli indispensable pour sa Watch
Appli vraiment sympa qui permet d’avoir l’œil sur la charge de notre montre ET son iPhone.
Aucun plantage.
Je recommande fortement.
Par ailleurs le développeur est très réactif et nous permet un dialogue aisé avec lui, en quête de solutions à nos problèmes.
Je ne peux que le féliciter dans sa démarche.

Merci pour la belle critique !
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 Tip my Hat 🎩 to you and say thanks it is truly a 5 Star ⭐️ App! “ Thanks !“

I’m glad you like the app and appreciate the time and effort I put into it! Thanks for the nice review!
Feature request
Please make a complication for the widget screen of the Apple Watch.
Everyday Utility
I’m grateful to be able to use such a solid app where Apple failed to provide. I benefit from this app dozens of times a day and recommend anyone who want to see their iPhone’s battery without needing to have their phone at hand.
Maybe I’m missing something?
When I found this app, I liked the idea of getting notifications that my watch is charged a certain percentage because I don’t like charging my watch to 100%. But when I got into the app it claims it has a Apple Watch compilation, but when I’m in the Apple Watch app I am not seeing a juice watch compilation option.

That seems to be a common iOS and watchOS bug. Please try turning both devices off and then back on. You may need to do this multiple times or wait several hours before it shows as an option. Also, make sure you have Juice Watch installed on your Apple Watch in addition to your iPhone. Contact me with the link in the app if you would like more assistance!
Nice app that’s hobbled by Apple
I love the complication this app provides: just a little bit more data on my wrist (I went from minimalist to ALL THE INFOS one day).
I really wish the app could update more often - as it stands, my watch went from 38% to 90% before it notified me I was charged over 50%. This is not the devs fault, Apple has knee-capped 3rd party apps on their update frequency.

Excellent app
This app is extremely handy.
You need to accept that it works within the constraints placed upon it by Apple, so it isn't as accurate as the apple proprietary monitoring of battery charge, but it's very good nonetheless.
I can monitor both my iphone and Apple watch battery charge levels and be alerted when they reach a designated level.
The notification function is superb, the 'bzzzzt' audio alert never fails to make me jump (or grin) - meaning I never miss it.
On the watch I have it vibrate which works well.
I appreciate that there are no ads and to acknowledge this and a splendid app I sent a few pounds to the developer.
Hopefully this will help maintain support - i wouldn't like to lose this one.

Ne fonctionne pas ?
Bonsoir, j’ai acheté cette appli et l’ai installée sur mon téléphone. L’appli me donne un message « aucune Apple Watch connectée » j’ai iOS 17.4.1 je ne vois pas quoi faire car ma montre est bien connectée ?
Merci de votre aide, cordialement
J’ai noté 5 etoiles car ça va certainement marcher après les lumières du développeur ☺️

Veuillez essayer d’éteindre les deux appareils, puis de les rallumer. Si cela ne le résout pas, veuillez me contacter avec le lien dans l’application.
Niveaux de batterie arrondis
La complication n’affiche que des pourcentages arrondis de 5 en 5 (exemple 50 puis 45 puis 40…). Dommage
Underrated
A big thank you to the developer for Juice Watch… the Juice Watch app is seriously underrated. It is so very helpful to be able to see battery percent on either the watch or phone. Seriously underrated.
Lack of customization
It does what it says, but there are no indicators for which battery charge is which device, and you can’t customize it for example if you want two gauges, or two text readouts.
This uses more battery than not using it.
I have background app refresh disabled on phone and watch in order to get more battery. iPhone have horrible battery life and if I have to turn background app refresh your to monitor battery this is wasting battery rather than helping.
A great tool to help get the most out of your batteries
If you’ve spent time on the Battery University website, you’ve likely read the ‘BU-808: How to Prolong Lithium-based Batteries’ article.
So, you’ll know that the Li-ion battery cells in your iPhone and Apple Watch do not love to be charged all the way up to 100% full, nor run down much below 20-30%.
So, how about an App that alerts you via a Notification, when your device’s battery is charged past 90%, or has run down below 25% (or, whatever pre-set charge levels you prefer)?
So that you don’t need to worry about remembering to check on charge levels throughout the day? And so that you can get an idea of your iPhone’s current battery-level with a glance at your Apple Watch?
‘Juice Watch’ is that App.
(Now, it’s not perfect; iOS and WatchOS will only update the App every so often, so notifications can sometimes come in a little later than might be ideal. Of course, the App can only work with the updates that the OS provides it with.
But, if you want to extend the life of your device batteries through good battery-care practices, this App is a great tool for it. It’s easy to set-up, and does what it says it’ll do. Getting an extra year or two’s service out of a battery makes it a good value proposition, in my opinion. Give it a try!)
