FAQs

  • "Can I use an android?" No. Check out AndroidAPS Documention.
  • "Can I use an iPad?" No. iPads do not support Apple Health and Loop uses Apple Health.
  • "Does my iPhone need a cell plan?" No. Loop works using communication on your phone with your CGM and your pump; no internet connection required. However, if access to Dexcom Follow or Nightscout monitoring of Loop is a priority, then a cell plan may be desired.

Which Devices Are Compatible?

Loop requires an iPhone or iPod touch. Loop uses the Apple Health app to store and retrieve your blood glucose and insulin data and to store your carbohydrate records. iPads do not have the Apple Health app, so iPads will not work with Loop.

You need a minimum version of the mobile operating software, called the phone's "iOS", to be installed on your iPhone or iPod touch. Loop is compatible with iPhone and iPod touch devices with iOS 12.4 or newer. The next version of Loop will require a minimum of iOS 14.

Find Your Device's iOS

Do not use any of the beta iOS versions. (Don't worry...if you don't know what that means, then you aren't using one.)

Developer Mode

With iOS 16 and watchOS 9, Apple added a feature. If you want to know more, click on this Apple Link about Developer Mode.

When you build Loop on your phone running iOS 16, and watch paired to your phone running watchOS 9, you need to have Developer Mode enabled. You can go on and enable it now - or wait until you reach the Build Loop App: Prepare your Phone and Watch instructions.

Developer Mode with iOS 16, watchOS 9

If you already have Loop on your phone/watch when you update to iOS 16/watchOS 9, you will be told that Loop requires Developer Mode to run.

You will not be able to run Loop until you have enabled Developer Mode.

Battery Health

Make sure the battery on your phone is solid. Your phone will become a critical health device - you want it to keep working.

With newer iOS (14 and 15), some people have reported Loop continues working even in Low Power Mode if you need to preserve battery; others, have reported they still get red loops.

Older iOS (and associated older phones) were reported to cause Loop to stop updating when the phone was locked. If you are running an older version of iOS (on an older device) with Loop 2.2.x, you may need to avoid Low Power Mode.

  • Consider buying a battery pack, keep it charged and add it to your travel bag

Turn Off Automatic Updates

Apple provides updates regularly to the iOS. Often, these updates include critical security patches in addition to improved new features.

Please be proactive - install updates as soon as the "Loop" all-clear is given.

If a limitation on your Mac prevents you from updating your phone to the latest iOS, please pay attention to security vulnerabilities.

Why Turn off Automatic Updates?

  • Once you accept an iOS phone update, you cannot go backwards
    • Some iOS updates require updates to Xcode and macOS before people can build Loop on that device again
    • It is rare, but iOS updates have caused Loop to stop working until other updates were made and Loop was rebuilt on that phone
  • Turn off automatic updates so you can choose when to update your phone and avoid being caught without a working Loop app
  • Google the instructions for your device:
    1. Configure your phone to automatically download the updates
    2. Choose to perform the installation of the updates manually

When iOS updates are released, check your favorite Loop Social Media site to see if the update is causing an issue with Loop or your CGM before accepting the update from Apple.

Within a few days, the "All-Clear" or "WAIT there's a problem" will be posted.

Older Builds

Updating to iOS 15 immediately stops the Loop app if it was built with Xcode versions 12.4 or earlier and requires a rebuild to continue Looping**

  • Look at an Issue Report to determine the Xcode version used to build Loop on your phone
