Dismiss the alarm, then drift back to sleep? WakeRally gives you a short Wake Flow to complete after your alarm rings, with an optional follow-up a few minutes later. BUILD YOUR WAKE FLOW Set one-time or weekly repeating alarms. Choose 1–3 missions from six types, arrange their order and set your targets. • Wake-Up Puzzle: answer multiple-choice math questions. • Number Order: tap the numbers from 1 to 9 in sequence. • Grid Recall: remember the marked squares, then select them after they disappear. • Matching Pairs: turn over cards to find matching shapes. • Shake Phone: complete your target of 1–10 shakes. • Photograph an Object: photograph a saved object or scan a registered QR code or barcode. Place your checkpoint object away from bed for a reason to get moving. Object matching happens on your device; completing a task does not guarantee that you are out of bed or fully awake. CHECK AGAIN A FEW MINUTES LATER Add a Stay-Awake Check 1, 5 or 10 minutes after the main missions. Shake to confirm, using the target from the first shake mission in your flow. If there is no shake mission, the check defaults to 3 shakes. REVIEW YOUR MORNING RECORDS Review completed sessions, streaks, your verification calendar and time spent. A Backup Mission is always available. To end a session, hold Emergency Stop for 3 seconds and confirm; the result is recorded as unverified. FREE AND PRO Free includes all six mission types, full editing of 1–3-mission flows, targets and follow-up timing, 2 enabled alarms, 2 checkpoint items, a 7-day summary and complete individual session history. Disabled alarms can be saved and edited without using an enabled-alarm slot. WakeRally Pro adds unlimited enabled alarms and checkpoint items, and expands summary statistics to 30 days. Monthly and yearly subscriptions renew automatically. Lifetime is a one-time purchase. All three options unlock the same Pro features; prices are shown on the purchase screen. PRIVACY AND CONTROL No account is required. Alarm settings, object features and wake records stay on your device. Original photos and raw barcode values are not saved or uploaded. The app contains no ads, analytics or cross-app tracking. WakeRally is not a medical product, does not guarantee waking you up and does not prevent you from stopping alerts through system settings.
