Aera plans running loops from your door, replays your recent runs in 3D over the real ground, and reads your sleep and recovery against your own usual, on iPhone and Apple Watch, with no account. Aera reads Apple Health on your iPhone. Every run, walk, ride and night is read against your own usual, and every number opens the article behind it. TODAY: HARD, EASY OR REST Your recovery, sleep, stress and recent training decide the call, free for everyone. With Premium, Aera writes today's session: how long and how hard. PICK A DISTANCE. AERA DRAWS THE LOOP. Up to three loops that start and end where you stand: one on ground you know, one new to you, and one off-road, or along cycleways on a ride. Size them by distance or by minutes. Where there is enough to see, a Sights loop passes the best-known places, and a loop past a viewpoint can be timed for the sunset. DRAW YOUR OWN Tap and the line keeps to real paths, or drag to draw freehand. The distance counts as you draw. Open a GPX file and it is ready to follow. EVERY TURN, BEFORE IT COMES Turn by turn on your iPhone and Apple Watch, spoken if you want it, with a word when you leave the route and when you are back on it. EVERY WORKOUT, EXPLAINED Splits, heart rate zones, climb and the effort the session actually cost you, against your own usual. Fly back over any run from the last seven days. READ AGAINST YOU, NOT AN AVERAGE Recovery, stress, strain and sleep are scored against a baseline learned from your own nights and sessions. While your history is thin, Aera says so instead of guessing. YOUR NIGHT, IN ITS OWN SHAPE The stages as they happened, the hours you slept, and how far that sat from the need Aera learned from you. EVERY NUMBER, EXPLAINED The Field Guide explains how each read is built, the research behind it, and where it stops being reliable. ON YOUR HOME SCREEN Widgets in every size, on the Home Screen and the Lock Screen. FREE Recovery, stress, strain and your sleep score, every day. Hard, easy or rest. Loops, the route planner and turn by turn. Every workout read, every personal best and your recap films. Flyover for the last seven days. Twelve months of history, and your raw data out as JSON or GPX. PREMIUM Today's session. Your sleep reserve. Your places. Flyover for older routes. Every route you draw kept (the first one is free). History past twelve months. Reports and every export format. Monthly, yearly, or once and yours for good. PRIVACY Health numbers stay on your iPhone. No account, no sign in. Your scores are computed on your iPhone, and there is no language model anywhere in the app. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
