Start an outdoor mile on iPhone—no Watch needed

Choose a safe outdoor route with a clear view of the sky. Warm up, then carry your iPhone during the run.

1. Open Train → One Mile → Start One Mile → Start on iPhone.
2. Allow Location While Using and turn on Precise Location for Proof Fit.
3. Wait outdoors while the app finds a ready GPS signal. Keep Proof Fit open through the countdown.
4. Start running after the countdown. You can then lock the screen; recording continues in the background.
5. Finish timing stops automatically at one mile. Review your completed result before sharing it.

Use the optional Apple Watch companion

Pair your Watch with your iPhone and install the Proof Fit companion using the Watch app on your iPhone. Open Proof Fit on the Watch and allow the requested running-distance and workout permissions in Apple Health.

Open the One Mile Challenge on iPhone and choose Start on Apple Watch when the companion is ready. If the button is unavailable, check pairing and companion installation. You can always choose Start on iPhone instead.

Watch recording can continue if your iPhone disconnects. Finish or cancel the attempt on the Watch. Saving the completed workout to Apple Health requires permission.

Location denied, weak GPS, or an interrupted mile

In iPhone Settings → Privacy & Security → Location Services → Proof Fit, allow While Using the App and enable Precise Location. Location Services must also be on. Always permission is not required for a user-started iPhone mile; it is used separately for automatic saved-gym check-ins.

Move outdoors with a clear view of the sky and wait for GPS readiness. If GPS is lost, permission changes, the app closes, or you cancel, check the attempt summary and start a new attempt when ready. Interrupted attempts do not count as completed miles or set a personal best.

Distance and finish timing are sensor estimates. Carry the phone throughout the run. The timer includes stops during the attempt.

Find and understand your challenge records

Open Train → select a challenge → results below its card → View results. Complete a challenge first if no history is shown. Saved results include dates; Latest shows the most recent saved result for that challenge.

Best set is your highest rep count in a single saved set, not a daily total. Longest hold is your longest saved plank hold. For the One Mile Challenge, Best on this phone is your fastest completed mile saved on the current phone for the current account; Latest mile is the newest completed result in that history.

Account sync does not make mile personal bests a cross-device leaderboard. Mile times and distance are sensor estimates.

Share a result or challenge a friend

Use the Share action on a completed mile result to open its share preview and choose a destination. Review what you are sharing; a result can include timing, distance, recording source, and challenge context, without a raw GPS route.

Create an account or log in to sync progress and use friend challenges. Sending a friend challenge is separate from exporting a result through the share sheet. No purchase is required to use core workout challenges or manual food logging.

Purchase optional Proof Fit Plus

Open Settings → Proof Fit Plus → choose Monthly or Annual → Get Proof Fit Plus. Selecting a plan only selects it; it does not purchase anything. Review Apple’s purchase confirmation, which shows the current price and subscription terms.

An account is needed to connect Plus and its AI credits. Plus supports AI-assisted food-photo analysis, voice meal logging, macro suggestions, and personalized meal plans. Core workout challenges, manual food logging, and barcode lookup remain free.

Restore, awaiting approval, or activation trouble

To restore a prior purchase, open Settings → Proof Fit Plus → Restore Purchases. Use the Apple Account that made the purchase and sign in to the Proof Fit account you want to connect.

Awaiting Approval means Apple’s purchase is still pending, such as an Ask to Buy request. Wait for Apple to approve or complete it; do not treat a pending request as a completed purchase.

If Apple confirms the purchase but Plus is waiting for activation, check your connection and choose Retry Activation in Proof Fit Plus. If access still does not activate, email support with the displayed error. Do not send passwords or payment-card details.

Choose Manage Subscription in Proof Fit Plus, or open iPhone Settings → [your name] → Subscriptions, to manage or cancel through Apple. Deleting Proof Fit or its account does not cancel an Apple subscription.

AI credits and data-sharing consent

AI requests use a credit allowance, and different features use different amounts. Review your available credits and How AI credits work in Settings → Proof Fit Plus. The allowance shown in the app reflects your entitlement.

AI features are optional. Before information is sent to OpenAI, LLC through our server, Proof Fit shows a disclosure and asks you to explicitly agree. Review or withdraw permission at Settings → About → AI Data Sharing.

Withdrawing permission stops future AI requests but does not delete existing food logs or other app data. Manual food logging and the rest of Proof Fit remain available. AI nutrition estimates are informational and may not be exact; review and edit entries before relying on them.

Camera, microphone, Apple Health, and other permissions

Camera, microphone, speech recognition, Apple Health, location, and notifications are optional. Allow the permission for the feature you choose to use; you do not have to enable every permission to use Proof Fit.

Review app permissions in iPhone Settings → Apps → Proof Fit (or Settings → Proof Fit on older iOS versions). Apple Health permissions can also be reviewed in the Health app. Workout camera frames and body-pose processing stay on-device; workout video is not uploaded or stored.

Account, sign-in, and password reset

Open Sign Up or Log In in the app. For a password reset, use the password-reset option on the sign-in screen. Account sync and friend challenges require an account.

Delete your account

Sign in, then open Settings → Account Actions → Delete Account and confirm. If deletion fails, check your connection and contact support. This removes your account and associated synced app data.

Deleting your account does not cancel an Apple subscription. Cancel separately through Manage Subscription or iPhone Settings → [your name] → Subscriptions. Previously exported results and Apple Health workouts are managed separately in their destinations.
