Log your food in seconds, not minutes

Calorie tracking works. Almost nobody argues with that anymore. The reason people quit is not the concept, it is the effort. Searching a database, guessing a portion, typing macros by hand: do that three times a day and most people fall off within a week.

Friction is the real enemy

Every second between "I ate this" and "it's logged" is a second where you might just not bother. Cut that time to near zero and the habit survives.

Rep N Prep gives you five fast paths:

• Scan a barcode. Point your camera at the packet. Macros filled in.
• Snap a photo. Take a picture of your plate and let the AI estimate the items and their macros, then tweak anything that looks off.
• Describe it to the AI. Type "two eggs, toast and a banana" and it breaks the meal into items with macros for you.
• Saved meals. Log a meal you eat often with a single tap.
• Share with family or friends. Eating the same dinner? Share a meal and they log it in one tap, no re-entering.

Fast enough to keep up

A calorie ring that adjusts for the calories you burn, macro bars that update live, and logging that takes seconds rather than minutes. That combination is what keeps the streak alive past week one, which is the only thing that actually moves the needle.

Get the loop tight enough and tracking stops feeling like admin. It just becomes something you do, like checking the time.
