  • Release Notes can be found here

iPhone 17

If you received a new iPhone 17 as a gift or you randomly decided to treat yourself to a new phone, please read the updated LoopDocs instructions before migrating to your new phone. You'll want to update to Loop 3.8.2 on your old phone (if you haven't already) before updating to your iPhone 17 with iOS 26.x.

Most browser builders have already updated, but some Mac-Xcode builders are still on Loop 3.4 or 3.6. If you are on Loop 3.4 or 3.6 and you update to iOS26, you will lose your ability to manually bolus until you update to Loop 3.8. Avoid the drama and rebuild first.

Help for Loopersusing GLP-1RA Meds

Here’s a Pro Tip that may help Loopers using GLP-1RA medications!

Add the Profiles customization and name your profiles after the medication level so that you can track changes- and easily revert if the medication dosage reverts back to a previous level.

More tips when adding a GLP-1RA:

  • Adjusting your carb absorption rate is necessary
  • Keep that glucagon handy - low treatments might not absorb as quickly

#BeyondtheNumbers

We have a great series of looping-related Resolutions shared on Loop and Learn Instagram and Facebook. If we take them to heart, we will become more informed loopers and experience more predictable outcomes, with less need for intervention. Be sure to check back over the next week!

Look for the hashtag: #BeyondtheNumbers

Resolution #1:

This year, I'll give myself the chance to build my own #OpenSource app with help from the community; because understanding is part of safety.
