Cut or bulk

Looks legit. Guides you the right way

Response from developer

Thank you so much! We’re really happy to hear that the app feels helpful and guides you in the right direction. Your support means a lot to us!

App with a lot of potential

App with excellent UI/UX, I just believe it would be interesting to add more languages like Portuguese BR.

Response from developer

Obrigado, Arthur! Good news, Brazilian Portuguese is now in the app! 🇧🇷 Just update to the latest version and you can switch right over. Your request was heard loud and clear. If anything reads oddly in the translation, let me know at support@0xcal.app — I want the pt-BR experience to be perfect.

Nailed the user experience

Most people don’t realize that if they want to lose serious weight they need to log what they eat. But when they do, they quit quickly because the apps are so bad. I realized ChatGPT could do this better than 99% of apps out there, including good estimation from photos… but it doesn’t work so well to have your log in an LLM chat. This app combines the best of both worlds and gets the chat user experience right. Maybe it’s the next MyFitnessPal.

Response from developer

Thank you so much for this amazing review! This is exactly the experience we’re trying to build — making food logging feel natural, fast, and less frustrating than traditional calorie tracking apps. We really appreciate your support and kind words!

UI is terrible

We get it you’re a developer. Why the text scroll that I can’t skip. Very slow on boarding. Camera should pick up barcode without having to click every time! Good luck

Response from developer

Hi, thanks for the honest feedback! We appreciate you taking the time to share your thoughts — it helps us improve. You raise fair points. Regarding the barcode scanner — great news, it's already built in! Just point your camera at a barcode and it'll pick it up automatically. Give it another try and let us know how it goes. We're a small team iterating quickly, so expect improvements soon. If you'd like to share any more details, feel free to reach out to us directly — we'd love to get it right for you.

This app is amazing

I love to simplicity of it! But also covers all the important things like Marcos calories and active levels. As well as adjust daily for Macros and calories based off of active levels and weight loss or gained. My only issues is recent the text option to add logs became too large for my phone and I can’t log anything. I hope the developer can fix this and I would rate this app a 15/10.
