Episode notes
Build The App First And Use Virtual Pump Mode
- Build the Android APS app yourself following the Docs page and run it in virtual pump mode first.
- Use the virtual pump for ~a week to stream CGM data, learn the UI, and prepare while waiting for supplies.
Start Simple Then Basal Test With A Coach
- Start Android APS with simple settings copied from your current pump, then work with a coach to basal test and refine.
- Expect about 1–2 weeks to reach a stable foundation after initial tweaks and testing.
Features Unlock Gradually To Build Reliable Data
- Android APS unlocks features gradually through objectives so the algorithm builds a data history before advanced functions.
- Progression moves from basic basal/carb settings to temp targets, closed-loop corrections, dynamic ISF, and SMBs.
