You know you "should eat more protein" — but every day is a guess. You track in your head, lose count by dinner, and have no idea if you actually hit your number.
PRO.TEIN fixes that in one motion: scan a barcode, protein gets logged, today's square fills in.
WATCH YOUR MONTH FILL IN
Your home screen is a continuous calendar heatmap — every day you've tracked, at a glance. Darker square, closer to goal. No spreadsheets, no math, just a record you can see.
BUILD A STREAK YOU WON'T BREAK
Consecutive days at goal become visible momentum. Once the chain is there, you don't want to be the one who breaks it.
KNOW YOUR NUMBER IN SECONDS
Scan any barcode and protein is logged automatically via Open Food Facts. No manual entry, no searching — just scan and go.
STOP GUESSING, START PROGRESSING
Consistent protein intake is what actually drives muscle gain and fat loss. PRO.TEIN turns "I think I'm doing okay" into a number you can trust, day after day.
DESIGNED TO DISAPPEAR
No clutter, no ads, no distractions — just a clean monochrome calendar and the food you ate. Built for people who train and want the protein to match the work.
