Aera vs Sleep Tracker

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/

Understand your signals. Shape your day around them. Cernidia helps you make sense of your sleep, recovery and daily energy, so everyday choices about rest, movement and focus have more context. See the bigger picture behind your numbers and notice patterns over time. No ads, subscriptions or in-app purchases. No Cernidia account needed. UNDERSTAND YOUR SIGNALS • Review your sleep and your next planned sleep window. • Follow your daily energy estimate and recovery in your personal context. • Explore breathing-rate trends, blood-oxygen readings and heart-rate zones when suitable data is available. • Add a quick check-in to record how you feel. CONNECT YOUR WEARABLES Use Apple Health with Apple Watch, or connect an existing WHOOP account. WHOOP Recovery, Sleep, Strain and Workouts are labelled separately. Connections are optional, and Cernidia remains usable without a wearable. PUT INSIGHTS INTO YOUR DAY Give tasks, routines and recovery time a place in your day. Optional calendar access helps your plans fit around real commitments. The Apple Watch companion shows your current and next activity, lets you record an energy check-in and adds heart-rate context to workouts you start. CHOOSE YOUR WAKE-UP WINDOW Smart Wake lets you choose a wake-up window and uses previously recorded sleep phases to estimate a wake time. Your latest wake time serves as a backup. Alarm or notification permissions are needed for alerts; Smart Wake does not detect your current sleep stage in real time. PRIVATE AND OPTIONAL Your health summaries, check-ins and plans stay on your devices. Cernidia has no app-data cloud sync, product analytics, advertising or cross-app tracking. The optional WHOOP connection uses an online authorization service. WHOOP health records are fetched directly to your iPhone and stored locally. WHAT TO EXPECT Personal comparisons need enough readable history. Missing data stays unknown. Features depend on your device, permissions and available records. Apple Watch and WHOOP devices are sold separately; WHOOP also requires its own membership. Cernidia supports general wellness and everyday decisions. It does not diagnose conditions or provide medical treatment recommendations.
