That 'high-protein' bar? See how much of that protein your body can actually use. Scan any barcode for its real, usable protein — collagen and filler exposed.
How much of your protein actually counts?
Not all protein is equal. The label says "30 g protein" — but your body can often put only a fraction of it toward building muscle. The rest isn't absorbed, or it's simply burned for energy. Protein Quality Scanner shows you in seconds how much actually builds muscle — and how to fix the weak spots by combining the right foods.
Scan a barcode, photograph the ingredient list, or search the built-in database. The app reads the amino-acid makeup and digestibility of every protein source inside and turns it into one Effective Protein Score from 0 to 100 — telling you how much of that protein actually goes toward muscle.
WHAT MAKES IT DIFFERENT
Most apps just add up grams of protein. This one counts only the grams that actually build muscle. The score is built on the established DIAAS and PDCAAS standards, weighted for a single goal: building and keeping muscle. It comes down to how well your body digests the protein and whether all the essential amino acids are there in the right ratio. If some fall short, the app tells you exactly which foods to pair it with to close the gap.
HOWEVER YOU EAT, IT MAKES YOUR PROTEIN WORK HARDER
Animal sources like whey, milk and eggs already bring a balanced amino-acid profile. Single plant proteins — rice, hemp, almond — often score lower on their own. That's no problem: usually just one amino acid is missing, and the right pairing fills it. The app shows you how to combine sources so the whole meal is balanced and your protein actually builds muscle — omnivore, vegetarian or vegan.
WHO IT'S FOR
For anyone in the gym who doesn't just want to eat plenty of protein, but actually turn it into muscle. For vegans and vegetarians hunting for complete protein combinations. For anyone after the real benefits of a high-protein diet. And for everyone fed up with empty "high protein" claims.
FEATURES

• Build a meal and watch the score climb in real time
• 3M+ products via Open Food Facts
• Free, ad-supported
• No account needed — your data stays on your device
THE SHORT VERSION
Your muscles need every essential amino acid in the right ratio. If one runs short, it caps the rest — the others can't be used effectively either. Cheap fillers like collagen put "protein" on the label but do little for muscle. The app does the math for you, so you never spend money on protein that won't build muscle.
Stop falling for empty "high protein" claims. Start scanning.

Search products by name
No barcode? No problem. Open the protein lookup and switch to the new Products tab to search Open Food Facts by name — complete with product photos so you can spot the right one at a glance. Tap a result to see its full Effective Protein score. The Foods tab still has all your generic protein sources (chicken, whey, and more) for quick offline lookups.
