About

Protyn

Every other protein app makes you log a full food diary to find out one number. Protyn is that number: the protein you have eaten today, against your goal. Open it, tap +30 g, done. No macro spreadsheets, no calorie guilt, no account. Protein is the thing people actually track in 2026 โ€” not total calories. So Protyn does one job properly instead of forty jobs badly. ONE NUMBER, ONE SCREEN - Your protein for today, in grams, in the middle of the screen. That is the whole home screen. - A ring that fills as the day goes and turns green the moment you hit your target. - Your streak of days on target, and nothing else competing for attention. - Calories are optional. Switch them off and Protyn really is one number. ADD PROTEIN IN ONE TAP - Quick-add buttons you choose: +10, +20, +25, +30 g. One tap, logged, gone. - A searchable database of 170+ foods that already know their protein, from chicken breast and Greek yogurt to whey powder, skyr, quark, tempeh and protein bars. - Every food ranked by how much protein it actually delivers per serving, not per 100 g of wishful thinking. - Your own foods: add your whey, your bakery's protein bread, your usual bar. Once. Then it is a tap away. - Your most-logged foods rise to the top automatically. THE SPREAD SCORE โ€” NOBODY ELSE MEASURES THIS Hitting 150 g in one enormous dinner is not the same as 150 g across four solid meals. Muscle protein synthesis is switched on by separate feedings that each clear a leucine threshold โ€” roughly 0.3 g per kg of body weight, about 25-30 g for most people โ€” and it responds best to around four of them, 3-5 hours apart. Every other tracker scores those two days identically. Your muscles do not. - Protyn grades each day from 0 to 100 on how well you spread protein out. - 50 points for how many feedings cleared your personal threshold, 30 for how even they were, 20 for landing the gaps in the 3-5 hour window. - A timeline of the day's feedings, showing which ones counted and which fell short. - One concrete tip, not a wall of numbers: eat more often, even out your biggest meal, or close that eight-hour hole. - Your threshold is calculated from your body weight, so it is your number, not a magazine's. INSIGHTS THAT ARE ACTUALLY YOURS - Daily protein trend with your goal line drawn across it. - A consistency heatmap: every square a day, darker as you approach your goal. - This week against last week, at a glance. - Which days of the week you slip โ€” most people fail on Saturday and never notice. - When in the day your protein actually lands, hour by hour. - Personal records: best day, best spread, longest streak, days on target. WORK OUT YOUR GOAL Not sure how much you need? Enter your weight and pick how you train โ€” sedentary, active, training hard, or building muscle โ€” and Protyn suggests a target from the 0.8 to 2.0 g/kg range the sports-nutrition research actually uses. PERFECT FOR Lifters and gym regulars tracking protein for muscle gain. Anyone in a cut who needs to protect lean mass. Runners and cyclists recovering between sessions. People over 40 protecting muscle as they age. Vegetarians and vegans who need to hit protein without animal foods. Anyone who tried MyFitnessPal, logged three days and quit. PRIVATE AND OFFLINE - No account. No sign-up. No cloud. - Every entry lives on your device and nowhere else. - Works on a plane, in a basement gym, anywhere. - Export everything to CSV whenever you want. It is your data. Six languages: English, Spanish, French, Italian, German and Portuguese. Protyn is not medical advice. It is a counter for people who already know they should eat more protein and just want the number without the homework.
