Waitlist & launch
When does Ratio launch?
We're finishing iOS testing now. Waitlist members get early access before the public App Store launch, plus a founding-member discount.
How do I get early access?
Join the waitlist with your email from the homepage — we'll email you as spots open up. You can join the waitlist here.
I signed up but haven't heard anything — did it work?
We don't send a separate confirmation email — you'll hear from us when Ratiō launches. If you're worried your signup didn't go through, email us at the address above and we'll check.
Using Ratio
How accurate is the AI, really?
Ratiō is trained specifically for portion and ingredient estimation, then cross-referenced against a verified nutrition database — so you get restaurant-and-homemade-meal accuracy, not a rough guess.
Do I need to weigh my food?
No. Ratiō estimates portions visually. You can always fine-tune a result, but most people never need to.
More questions about how Ratiō works are answered in the FAQ and comparison sections on the homepage.
Account & privacy
Questions about what data Ratiō collects, how it's used, or how to delete your account and data are covered in full in our Privacy Policy.
Looking to delete your account specifically? See Account & Data Deletion for step-by-step instructions. Note that deleting your account does not cancel an App Store subscription — see Subscriptions & Billing for how to cancel.
The rules for using Ratiō — your license, subscription and billing terms, and important health disclaimers — are in our Terms of Service.
