Reviews
People who used to quit tracking.
Now they don’t.
★★★★★
I have deleted four calorie apps in my life. This is the first one I have kept past a week, because I actually use it.
★★★★★
The photo estimates are close enough that I stopped second-guessing and just logged. That consistency is what finally worked.
★★★★★
I love that it celebrates every meal. It sounds silly, but the little confetti keeps me coming back.
★★★★★
Restaurant meals used to be a black box. Now I snap the plate and move on with my evening.
★★★★★
Finally an app that does not want me to weigh rice. Three seconds and done.
★★★★★
Clean, fast and honest about when it is unsure. That is more than I can say for most AI apps.
FAQ
Questions, answered.
How accurate are the photo estimates?
For everyday meals TrimByte is usually within the same range a dietitian would eyeball. It shows a confidence level with every estimate, and you can adjust portions before logging. It is built for consistency, not lab precision.
Is TrimByte free?
You get a 3-day free trial with full access. After that, choose a weekly, monthly or yearly plan, or buy lifetime access once. Cancel anytime from your App Store or Google Play settings.
Which devices does it work on?
iPhone and Android, with a companion web app for reviewing your history on a bigger screen. Your account works across all of them.
What happens to my photos?
Photos are sent securely for analysis and are not stored on our servers or used to train models. Your meal log stays on your device.
Can I set my own calorie and macro goals?
Yes. TrimByte suggests targets from your age, height, weight, activity and goal, and you can override any of them in Settings.
