iFell

iFell – Fall Detection, Heart-Rate Trace & Orthostatic Check Stay safer, stay informed — backed by your Apple Watch.
▸ What it does iFell pairs Apple Watch's built-in fall detection with a 2-minute post-fall heart-rate trace, so when something happens, you get more than just an alert — you get a precise, time-stamped record of how your body responded. Add a 3-minute orthostatic stand test, longitudinal trends, and a shareable PDF report, and iFell becomes a working safety + heart-health log you can hand to a clinician.
▸ How it works Apple Watch¹ runs fall detection in the background. The moment a hard fall is detected, iFell automatically opens a 2-minute heart-rate recording on the watch and relays the trace back to your iPhone. When the recording finishes, you get a notification with an inline chart thumbnail showing the heart-rate range you experienced over those two minutes — tap it to jump straight to the full trace plotted against resting / normal / elevated / peak HR zones.
All data stays on-device and in Apple Health. iFell never transmits it to any external server.
