Fantastic app and great scanner. I wanted something minimalistic and easy to use and track, and this fits the bill perfectly and I got the yearly subscription. I wish we could connect to Google account so that we don't lose all the data in case something happens to the phone, and secondly, they need to offer a trial so people can try. I was initially able to add 3 items and then it asked me sub for more. I couldn't try another item even if I deleted those 3, so that is a scope for improvement.

Really appreciate the kind words—so glad CalZen fits your style! Totally hear you on both points. We’re working on account sync to prevent data loss, and we’ve had lots of feedback about free trials, so that’s on our radar too. For now, feel free to reach out anytime at calzen@42apps.io with ideas or questions!

I regret downloading this app. It’s probably the worst calorie calculator out there. You’re forced to sign up, enter your weight goals, and go through the whole setup—only to find out you can use it for just one day. After that, they lock everything behind an overpriced subscription. Total waste of time.

Really sorry it felt like a letdown. The AI scans do need cloud processing, so we offer a few free tries, then a subscription covers the rest. We totally get wanting to explore more before committing—your feedback helps us figure out how to make that better. Feel free to share more at calzen@42apps.io.

it's quite unreliable - is asignes different number of calories to the exactly same thing! for instance coffe with oat milk - on Monday it has 18 calories, on Tuesday 80 cslories, on Wednesday 60 calories, on Thursday 40 calories....I subscribed because the super short "trial" seemed to wprk ok. Su, where do I cancel my autorenewal? even that is not clear in this app! Shady business...

Really sorry for the trouble — we totally hear your concerns. Since our AI estimates from photos, lighting and angles can affect results. Including a hand or fork in the photo might help with consistency. For subscription or cancellation help, please email us at calzen@42apps.io — we’ll sort this out quickly.

What’s new

We fixed a few bugs—including one that was blocking some users from resetting their goal. Everything should run more smoothly now.

Pro tip: Adding some healthy fat—like avocado or olive oil—to your meals can help with nutrient absorption and keep you feeling full longer.

Update now and stay consistent!
