LoopFollow¶

LoopFollow is an open-source DIY (do-it-yourself) app that displays information for a person with diabetes in an easy-to-use interface. It combines information from multiple other apps and provides custom alerts. It runs on iPhone, iPad or Mac devices. With newer versions, some remote control features are available for the Loop and Trio apps.

LoopFollow was created because using different apps as a parent or caregiver of a person with diabetes can be cumbersome. Add in the extra details from looping with an Open Source Automated Insulin Delivery (OS-AID) app and flipping back and forth between various sources of information can be a challenge. Many loopers use LoopFollow for themselves because of the flexible (and loud) alarm options.

LoopFollow:

• Displays information from a Nightscout Site or Dexcom Share account
• Provides flexible alarms with a Snooze screen
• Displays Treatments and Statistics (requires Nightscout Site)
• Supports Loop and Trio OS-AID systems
  • Provides secure remote control (requires Nightscout Site and security configuration)
• Supports up to 3 loopers – each with their own unique app name
• Works with your Apple Watch
• Runs on an iPhone, iPad or a Mac computer
