Frequently Asked Questions

How do I get the most accurate scan?

Take the photo from above, in good light, with the whole portion in frame and nothing covering the food. For packaged food, scan the barcode instead of photographing the box. If an item or a portion looks off, tap it and adjust the grams; the day’s totals update straight away. All nutrition values are estimates and should not replace advice from a registered dietitian or physician.

What iPhone models are supported?

Numi works on any iPhone running iOS 18.0 or later, and for the best camera results we recommend iPhone 12 or newer. The App Store also offers Numi on iPad, Macs with Apple silicon and Apple Vision Pro, where it runs the iPhone version. Meal analysis runs on our servers rather than on your device, so scanning speed depends mostly on your network connection.

Where are my meal photos stored?

When you scan a meal, the photo goes to our AI provider (OpenAI) for analysis and is saved to your own private storage area, so the meal appears in your history on every device you use. We strip GPS metadata before upload, we never sell your data or share it with advertisers, and we don’t use your photos to train AI models. To remove a photo, delete the meal; to remove everything, delete your account (see below). Read our full Privacy Policy for details.

How do I install Numi?

Numi is on the App Store for iPhone. Download Numi, open it, and tap Get Started — you can scan your first meal straight away, without creating an account.

How does Numi Pro billing work?

Numi itself is free, with 5 AI meal scans a day. Numi Pro is an optional auto-renewing subscription that removes the daily scan limit and unlocks the full Progress and Weekly Report features.

Subscription lengths and prices are shown in the app before you buy, and payment is charged to your Apple Account at confirmation of purchase. Your subscription renews automatically at the then-current price unless you cancel at least 24 hours before the end of the current period. Manage or cancel any time in Settings → [your name] → Subscriptions on your iPhone, or via this link. Full terms are in § 5 of our Terms of Use.

How do I restore a purchase on a new iPhone?

Sign in to the new device with the same Apple Account, open Numi, go to the Numi Pro screen and tap Restore Purchases. Your subscription is tied to your Apple Account, not to the device.

How do I report a bug?

Email hello@getnumi.app with a description of what happened. Please include your iPhone model, your iOS version, and the steps to reproduce it — a screenshot helps a lot.

The app crashed. What should I do?

First, try force-quitting and reopening Numi. If the crash repeats, email us with what you were doing at the time and your iPhone model. If you have crash sharing turned on in Settings → Privacy & Security → Analytics & Improvements, the crash report reaches us automatically too.

How do I delete my account and data?

In the app, go to Profile → Account → Delete Account. This permanently deletes your profile, nutrition history, meal photos, and all associated data from our servers.

If you have been using Numi as a guest without signing in, email hello@getnumi.app and we will remove your data for you. Deleting your Numi account does not cancel an active subscription — cancel that separately through Apple (see above).
