I liked using it (the paid version) but after three days I noticed it's not doing the math right, especially if you edit an item or add servings. I contacted support twice with screenshots but no response. I don't know if the developers are still even working on this? Update: I have now emailed them twice and no response. I have contacted Google Play and asked them to issue a refund for a defective app that I bought less than a week ago and it was denied. This is a scam.

Really sorry you’ve had this experience—and thanks for sending those screenshots, that helps a ton. Our team is definitely still active and working to improve things. Sounds like something’s off with the serving edits, and we’d like to dig into it. Can you follow up at [email protected] so we can get back to you directly?

All it does is count calories, even on the $10 per month plan, which I had to buy to add more than 3 items on day 1 (it is NOT FREE) Despite all the fancy talk about comprehensive macro and managing diabetes, it just track calories, protein, fat and carbs. Can't even track weight. It is easy to record meals, you can take a picture which works reasonably well or write a description. No need to guess how many grams or ounces things are.

Thanks for your feedback! CalZen tracks calories and macros using AI from food photos, but we hear you on wanting more features like weight tracking. We’re always improving, so your input is super helpful! If you have ideas on what you'd like to see, let us know at [email protected]. We appreciate you trying the app!

Adding meals by taking a picture is great. However, there are barely any other features in the app and plenty of bugs. For example, if you change the number of servings of an item (or any other value), the numbers do not update for the daily overview. Management of favorites and the interface are poor, to say the least. You can't even explicitly see the summed up calorie intake, just how much of your budget is remaining. For an app with 5 EUR/month subscription, I'd expect way more.

Thanks for the honest review—it really helps us improve. You're right, the daily overview and serving updates should work better, and we’re working on fixing those bugs. We’re also planning UI and feature upgrades soon. If you can share more details, contact us at [email protected].
