FAQ
Frequently asked questions
How does the AI food recognition work?
Take a photo of your meal and Lock's AI analyses the image to estimate calories and macros. The more centred and well-lit the photo, the more accurate the result. You can edit any entry, and for packaged food the barcode or nutrition label gives exact numbers.
Why did I run out of AI scans today?
Your first week has unlimited AI scans. After that, the free plan includes 8 photo or nutrition-label scans a day, resetting at local midnight. Barcode and manual logging are never limited, each friend who joins with your invite code adds 5 bonus scans, and Pro removes the limit.
How do I add friends?
Go to the Social tab and tap "Add Friend". You can search by username or share your invite code from your Profile card in Settings → Contacts.
How do I change the app icon?
Go to Settings → App Icon and pick Open Lock, Ring, Sticker or Keyhole. iOS shows a short confirmation after you switch.
How do I cancel my subscription?
Subscriptions are managed by Apple. Go to Settings app → Apple ID → Subscriptions → Lock, and tap Cancel Subscription.
How do I delete my account?
Go to Settings → Account Security → scroll to Danger Zone → Delete Account. This permanently deletes all your data.
Why isn't Apple Health syncing?
Go to Settings → Health Connections and make sure the toggle is enabled. iOS manages Health access in the Health app: tap your profile → Apps → Lock, then turn on Steps and Active Energy.
I lost my progress after reinstalling. Can I recover it?
Your data is tied to your account, not your device. Sign back in with the same account (Apple, Google, or email) and your history will be restored automatically.
