Beyond the photo
What the camera can’t see — just tell it.
The camera sees the plate, but only you know how much you actually ate, what was in the sauce and what you drank with it. Write one sentence in the chat, and Meyuman updates the meal and the day’s totals.

Frequently asked questions
How accurate are the estimates?
Calorie and macro estimates are approximate, like any estimate of a meal that wasn’t weighed. The more detail you give (amount, portion size, how it was cooked), the closer the estimate. And if something’s off, one sentence in the chat fixes it.
What happens to my photos and messages?
To analyze a meal, your message or photo — together with the context it needs from your diary — is sent for AI processing. A voice message is turned into text by iOS speech recognition; the app doesn’t send us the recording. The diary itself stays on your device (and in the device’s iCloud backup, if it’s turned on), and we have no server that keeps your history.
How much does it cost?
A 7-day free trial for new subscribers, then a monthly or yearly subscription. Prices are shown on the app’s App Store page. You can cancel anytime in your App Store settings.
Is there an Android version?
Not yet — Meyuman is currently available only for iPhone.
Can I move my diary to a new phone?
Yes — export your diary to a file and import it on the new phone.
