NoFlake: Promise Tracker
Accountability & Workout Proof
Only for iPhone
Free
iPhone
Promise to run, train or show up. Verify the result with Apple Health workouts or your location at the venue, and invite friends to keep their own promises.
NoFlake is a promise tracker that turns intentions into verifiable results. Commit to a 5 km run, a workout or meeting friends, then check the outcome with Apple Health workout records or your location at the venue. A checkbox alone does not count. Invite friends, follow your commitments and see who showed up.
A PROMISE IN A FEW TAPS
Choose an activity, a goal, and a deadline. For an arrival, choose a place and time. Running, cycling, swimming, strength training, walking, hiking, and arrivals belong in one timeline. Running goals include 15 km, a half marathon, and a full marathon.
PROOF BEATS CHECKBOXES
NoFlake uses HealthKit to read Apple Health workouts with your permission. A workout must match the activity, target, and time window. One qualifying workout counts toward one promise, starting with the earliest eligible promise. Shorter workouts are not added together, and manually entered workouts do not count.
For arrival promises, tapping “I’m here” checks a fresh, sufficiently accurate location against the venue’s range and time window. Optional arrival detection can check in the background, subject to iOS availability.
SHOW UP TOGETHER
Invite friends through a link or their account ID. Everyone joins in the app and fulfills their own promise. Sign in with Apple to access your account and recover account-based commitments on another device. Invitation webpages offer a preview; they do not let visitors join or mark a promise complete.
YOUR WORD, IN FULL COLOR
See kept promises and the ones you flaked on, filter your records, and explore a color-coded annual view. Open a record to see its outcome and available evidence. Your Promise Score and pigeon make progress personal; they are not a credit rating or a measure of someone’s character.
WINS WORTH SHARING
Choose a result card, a group status list, or a podium of finishers. Pick encouragement or a little dry humor, with a pigeon to match the moment. You choose when and where to share.
YOUR DATA AND CHOICES
Sign in with Apple is required. Workout verification needs Health read access; arrival verification needs location access. NoFlake does not write workouts to Apple Health. Raw routes, heart rate, and full workout files are not uploaded to NoFlake. Limited workout summaries are sent to verify account-based promises, and completion records are stored with your account and visible to accepted members as applicable. Full local Health evidence and older local promises do not sync through your account. Verification timing depends on Health syncing, permissions, network access, and iOS availability.
