## What it is
AndroidAPS is an open-source automated insulin delivery (closed loop) system for people with type 1 diabetes, running on Android smartphones. It connects to insulin pumps and continuous glucose monitors to automatically adjust insulin dosing.

## Use cases
- automate insulin delivery with a closed loop system
- connect an insulin pump to a CGM for automatic dosing
- manage type 1 diabetes from an Android phone
- build a DIY artificial pancreas
- track blood glucose and insulin on my phone
- integrate with Nightscout for diabetes data

## When to choose
- you have type 1 diabetes and a compatible insulin pump and CGM
- you want an open-source, self-controlled looping system on Android
- you want integration with the Nightscout ecosystem

## When to avoid
- you need a medically certified, FDA/CE-approved device
- you use iOS or non-Android platforms
- your pump or CGM model is not supported

## Facets
