  1. 5/5Nailed 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.

  2. 5/5This 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.

  3. 5/5Simply the easiest way to track macros

    I’ve been waiting for something like this. I don’t care enough to input every single meal or even vaguely input every single meal. This is so easy. I just talked to her. Tell him what I’m eating everyone’s well snap a picture if it needs more clarity and I’m done. I don’t even think about it.

  5. 2/5UI 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
