Loop Follow

Using so many different apps as a parent or caregiver of a T1D can be very cumbersome. Add in the extra details from Looping and it can be a challenge flipping back and forth between apps. Each app has different strengths and weaknesses.

• Spike is great for alarms.
• Spike and Sugarmate are great for the calendar complication on Apple Watch.
• Nightscout X or Nightscout in Safari are needed for intricate details from NS.
• IFTTT and Pushover are needed for Not Looping alerts.

And there are some functions I've always wished for and not found anywhere such a one-time temporary alert for those nights when Loop is stuck on high and you open loop with a correction. This lets you set a higher low alert for the BG you want to wake up to and close Loop.

Special thanks to Spike-App, NSApple, and Nightguard for helping me figure out how to do a lot of the code for this.

If you want to contribute, the biggest needs today are to make the code cleaner and more efficient, get some major details like Bolus/Basal graph and mg/DL vs mmol added, and create the basis for a watch app.

General feature list

• scrollable/scalable graph display with standard Bg details plus Loop status, Loop Prediction, and the General NS Care portal info.
• option to override DND and system volume for all alerts.
• snoozes per alert, presnooze, edit existing snooze, and snooze all alert settings.
• the standard Low/High, Urgent Low/High, and missed reading alerts. High will have a persistence option that’s still to do. Eg high for x minutes.
• fast drop/rise alerts with BG limits. Eg Trigger fast drop only when under a BG where it’s an issue.
• sage/cage reminder alerts for x hours before change.
• Not Looping with Bg limits. So you can trigger the alert only if under or over a BG range.
• calendar entries to use watch complication with BG, arrow, delta, cob, iob and minutes ago (if old reading).
• background silent audio to keep iOS from killing the app. It has a selectable refresh rate that should help reduce battery usage. This is why it can’t go in the App Store for just a simple download.

New functionality under consideration

• basal, carb, and insulin entries to the graph.
• missed bolus alert.
• watch app.
• mmol support.
• ability to pull from dex share for Bg. So it can automatically switch to dex BG display for those times when NS has delayed readings.
