Renzy vs Yazio
Both count calories. Only one is built around AI: photograph your plate and get calories, macros and micronutrients.
Yazio
Why switch from Yazio?
Ads in the free version
The ad-free experience and several key features sit behind PRO. Renzy never shows ads.
Photo scanning is an add-on, not the core
In Yazio the photo scan is one more PRO feature; in Renzy it IS the app: snap a photo and you're done.
Crowdsourced database with errors
Many entries are user-created and carry wrong macros you end up double-checking by hand.
Your daily goal, not a generic number
Yazio counts the calories you eat; Renzy works out your daily goal from your data and adjusts it to your cycle phase.
When to choose Yazio over Renzy
Yazio does two things well and it is worth saying so: a broad recipe catalogue inside the app itself, and intermittent fasting logging integrated with the food diary. If you cook from the app's recipes and want the calories logged automatically when you pick one, that saves steps. It is also well established in the German market, with local products well covered. If your day is "pick a recipe, cook it, log it", Yazio fits.
The verdict
Yazio asks you to choose from its catalogue; Renzy asks for a photo of what is already in front of you. They are two different philosophies serving different people: the first works if you plan, the second if you improvise. We add native AI scanning on every tier, zero ads, four languages with their own content in each, and a free public fasting calculator you can use without signing up. If you live inside a recipe book, Yazio. If you eat whatever turns up and want it logged in five seconds, Renzy.
FAQ
Does Renzy track intermittent fasting?
We have a free, public intermittent fasting calculator that gives you your eating window for the protocol you pick, with no account needed. You can try it before deciding anything.
Which is better for Spanish food?
This is where the gap shows most. Yazio covers the German market well, which is where it comes from. We work with dishes from here and, more importantly, do not depend on the dish existing in a catalogue: if it is in the photo, it gets estimated.
Are there ads on the free tier?
Renzy has no ads on any tier, neither during the trial nor on Pro. It is a product decision: the app does not sell your attention or your data to third parties.
