How do I change my eating window?

Go to Plan › tap a day and drag the handles on the 24-hour dial. You can copy a day to the whole week, to weekdays or to weekends.

Can I use LeanFast without an account?

Yes. Everything works offline on your device. An account only adds backup and sync.

How do I restore my purchase?

Go to Settings › Restore purchases, signed in with the same Apple ID you used to buy.

How do I cancel Prism?

Open the iPhone Settings app › your name › Subscriptions › LeanFast.

What can Lens scan?

Three things: a plated meal, a product barcode or QR code, and a nutrition label in EU or US format in the supported languages.

How do I delete my data?
