“Down 20 lbs in 3 months. CalZen changed my relationship with food.”

CalZenCalZen user

I've tried every calorie counting app out there, and CalZen is the first one that actually stuck. Just snap a photo of your meal and it instantly breaks down all the macros. No more tedious manual logging or searching through databases. The AI recognizes even complex homemade dishes. Down 20 lbs in 3 months and finally understand what I'm eating!

I have severe ADHD, nearly crippling, and AI has been a godsend to me. This app schedules tasks with minimal interaction.

Beautiful and well designed app. It gives my ADHD brain all the dopamine it needs to stay focused.

Easily upload a video and it quickly transcribes the dialogue. Marked timestamps make finding specific statements easy.
