CamAPS FX (CamDiab, Cambridge, UK) is a hybrid closed-loop app hosting the Cambridge closed-loop algorithm on an Android smartphone, and is approved in the EU for use in children ≥1 year, and adults (including during pregnancy) with type 1 diabetes (T1D). The interoperable CamAPS FX app receives glucose data from a compatible CGM system (Dexcom G6; Dexcom, San Diego, CA), connects to a compatible insulin pump (Dana Diabecare RS and DANA-i; Sooil, Seoul, South Korea) to direct glucose-responsive insulin delivery every 8-12 minutes, includes a bolus calculator allowing discrete bolusing via the app, and streams data in real-time to cloud-based diabetes data repositories (Diasend/Glooko, Gothenburg, Sweden).
