Sign-up, access, payment.

How do I cancel my subscription?

AI, foods, recipes.
The photo scan gives me weird macros
The AI can be off on composed dishes. Tap the result to adjust manually.
How do I add a missing food?
Settings > Foods > Add. We review your additions and merge them into the base if relevant.
Can I scan recipes?
The AI scan detects dishes, not complex home recipes. For those, create the recipe manually in Meals > Recipes.

Free has 3 AI scans per week. Standard has 5 per day. No difference in calculation quality.
Are the recipes halal-friendly?
Yes, toggle Halal in Settings > Nutrition. Recipes containing pork/alcohol are excluded.

When you miss a day, a shield is automatically consumed to preserve your streak. Free: 1/month, Standard: 2/month, Pro: 5/month.
My streak broke even though I logged
Check the time zone in Settings. The streak is computed on the local date.
