How do I log a meal?
Type what you ate, use your voice, or take a photo of the plate. Nüwa estimates calories and macronutrients. Check the portions and adjust them as needed. A remembered meal can be logged again with one tap.

Frequently asked questions
Find the topic you need help with.
Can I correct an estimate?
Yes. Check the ingredients and portions before logging. Estimates can contain errors; when details are missing, Nüwa asks follow-up questions to refine them. Use the values to track your food intake, keeping in mind that they are not exact measurements.
How are my targets calculated?
Initial targets use your profile, activity level, and goal. Measured maintenance is a paid feature: after three weeks with enough data, Nüwa can compare your logged intake with your weight trend and propose adjustments.
Why has my weekly review not appeared?
The Nüwa Pro review appears on Mondays and needs at least 3 logged days from the previous week. Check that your subscription is active and that you logged enough days during that period.
What is the difference between free and Pro?
The free plan allows unlimited manual logging, up to 3 AI calls per day, and access to 7 days of history. Pro removes the daily AI limit and includes full history, a weekly review, an automatic daily plan, unlimited saved dishes, and a full macronutrient breakdown. Use remains subject to the terms of service.
How do I cancel a subscription?
In Google Play, open Payments & subscriptions > Subscriptions. On Apple devices, open Settings > your name > Subscriptions. Use the store account you purchased with. Deleting the app or your Nüwa account does not cancel a subscription; cancel through the store before the next renewal.
How do I restore a purchase?
Sign in to the store with the same Apple or Google account used for the purchase. In Nüwa Settings, select Restore Purchases. If Pro is still unavailable, contact us using the email above.
How do I change the app language?
In your device settings, open the language options for Nüwa and choose Portuguese or English. Close and reopen the app after the change.
How do I delete my account and data?
In Nüwa Settings, select Delete Account. You can also request deletion by email using the instructions below. The privacy policy explains what is deleted, retention exceptions, and how backups are handled.
