Starting Loop: Compatible iPhone/iPod
Please refer to the details in LoopDocs for more information.
Important Fact: Loop is integrated with the Apple Health database. Loop reads from and writes to that database. Therefore, only an iPhone or iPod can be used with Loop. The iPad does not have Apple Health so you can’t Loop with it.
There are several versions of Loop you can build. Some versions can run on iPhones and iPods with iOS 12, others require iOS 13. Be patient, we’ll get to to the versions later.
iOS 12 as minimum requirement
Compatible devices that will run Loop but cannot accept an operating system newer than iOS 12.4:
- iPhone 5s
- iPhone 6
- iPhone 6 plus
- iPod touch (6th generation)
Warning – these devices will soon stop being compatible, so if you can, choose an iOS 13/14 compatible device.
iOS 13 and 14 compatible devices
This is a list of Loop-compatible devices that are compatible with iOS 13 and/or 14 (older devices first).
- iPhone 6s
- iPhone 6s Plus
- iPhone SE (2016 model)
- iPhone 7
- iPhone 7 Plus
- iPhone 8
- iPhone 8 Plus
- iPhone X
- iPhone XR
- iPhone XS and XS Max
- iPhone SE (2020 Model)
- All iPhone 11 and 12 variants
- iPod touch (7th generation)
A backup phone is recommended for Loopers (it does not need to be activated with a telephone number/mobile service).
There are alternate markets to purchase used cell phones (for example, https://swappa.com) to look for good used phones.
All looping phones should have an internal battery with a Maximum Capacity above 85% (look in Settings/Battery/Battery Health/Maximum Capacity).
Although the 12.4 devices are currently supported in some versions of Loop, they will be the first devices dropped from Loop in the future.
Apple iOS and Mac OS and Xcode
When Apple releases a new phone operating system (iOS), a new version of Xcode is also released. Xcode is used to build apps for Apple Devices.
When a new iOS is released – wait until you get the all-clear before updating your phone. That’s why you need to keep automatic update turned off on your phone.
Once you see reports that it’s ok to update your phone, it’s a good idea to update Xcode to a compatible version too, just in case you need to rebuild.
It is recommended that you practice rebuilding Loop at least once a quarter. This encorages you to keep your computer, Xcode and iPhone available to rebuild the Loop app if some new feature or safety concern is reported. For later reference, there’s a page on Version Updates.
