CalTrak is a calorie and macro tracker for iPhone and Android. It's free, there's no account, there are no ads, and the AI logging is free too. Your food log stays on your phone.
I'm Ryan, and I built it because I wanted to track my own calories without signing up for anything or paying to scan a barcode. It's grown to 4,000+ downloads, with a 4.9-star App Store rating from 99 ratings. Everything about it is below.
