Control your Quell device and monitor your pain relief with the Quell app. Tap the Quell complication to open the app. You can then start or stop therapy, increase or decrease intensity, view your therapy schedule, and get status information for your device. If you just want to check the battery level, that is available by glancing at the Quell complication. The app also offers notifications, like an alert when your Quell battery is low or if therapy unexpectedly halted, to make sure you never miss out on pain relief. ## Key features - Start/stop therapy - Adjust intensity - View therapy schedule - Check device status - Monitor battery level - Receive notifications ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/quell/id1517092922/reviews.md ### 4/5 — Must Install directly from Apple Watch, not iPhone *2021-09-17, version 1.0* In order to re-add the Quell app to your Apple watch, it needs to be downloaded directly from your watch. What you want to do is go into your watch and open your apps. Find the App Store app and open it there. You will want to search Quell Relief. When you are spelling it out, please make sure to spell the entire word out because, for some reason, it will not search partial words. Once located, there will be a button on your watch for you to download the app. I hope this helps someone! ### 4/5 — MUST INSTALL FROM WATCH NOT PHONE *2021-05-03, version 1.0* I had the same issue after downloaded the Quell app to my new phone. I went to the AppStore icon on my watch, searched for the Quell app and it popped right up and installed. Hope this helps! ### 1/5 — Won’t install *2021-03-28, version 1.0* Like all the others I had this working, but got a new watch/phone and this app isn’t even available to install in the watch. ### 1/5 — Same Problem- will not install *2021-01-24, version 1.0* App was working great until I had to reset my watch. Now the Watch app will not install even though the phone app works perfectly. ### 1/5 — Apple Watch app not showing with iPhone 12? *2020-11-01, version 1.0* I purchased the iPhone 12 pro and now the Quell app is no longer available on my watch. Please address this ASAP!! ### 1/5 — Will not install *2020-10-24, version 1.0* Ok so I had this installed on my Apple Watch 6 and it was working great. I just upgraded to the new iPhone 12 Pro and started it as a clean install. So that means I had to wipe my watch and start it as a clean install as well. I big deal right? Wrong. For some reason the Quell iOS app works and I can control the quell from it but the watchOS app will not install. Same Apple Watch just fresh install. Why won’t this app work? ## Frequently asked questions about Quell ### What can I do with the Quell app? The Quell app allows you to control your Quell pain relief device.
