Renzy vs Cal AI
Both scan your food from a photo. Only one checks its foods against BEDCA and also works as a web app.
Cal AI
Why switch from Cal AI?

When to choose Cal AI over Renzy
Cal AI does the same essential thing we do — photo, calories, macros — with a very simple interface and almost nothing to configure. If all you want is to open, shoot and see a number, that simplicity works in its favour. It is also the option with the most traction among a younger audience, so if your friends use it and you compare streaks, there is a social reason that appears on no feature table.
The verdict
This is the fairest comparison of the set, because both apps start from the same idea: photo first. The difference is not the scan, it is what sits around it. Renzy publishes its margin of error at /precision instead of promising round accuracy, runs as a web app with nothing to install, and bills in euros. If you want the minimal version of photo scanning, Cal AI delivers. If you want that scan wired into a daily target and your context, there is more application underneath here.
FAQ
Which is more accurate at scanning food?
No app can give you an exact figure from a photo: the portion is estimated, and that is where most of the error lives. What you can demand is that they tell you how wrong they are. We publish our average error at /precision and keep it updated — compare it against whatever any alternative publishes before believing a number.
Does Renzy work without installing the app?
Yes. Alongside iOS and Android there is a web app, so you can scan and log from a desktop browser. It is useful for meals at the office and for reviewing your week on a big screen.
Does Renzy work for Spanish food?
Yes. Foods are checked against BEDCA, the Spanish food composition database, as well as USDA, so dishes and products common in Spain do not depend on a database built for another market.
