Our story

Why we built
Protn.

Every other protein app felt like a job. We wanted one that felt like a game.

The Problem

Protein is the one macro that actually matters for most people — for building muscle, staying full, and body composition. The research on this is clear. And yet most people consistently under-eat it without realising.

We tried every tracking app. They all had the same problem: they were built for obsessives. Massive food databases. Macro breakdowns. Barcode scanning every meal. Calorie deficits. It felt like accounting.

Most people don't want to become nutrition experts. They just want to know if they're eating enough protein today.

"No reminder notification ever made me log a meal. Seeing my friend at 180g while I'm stuck at 90g at 6pm? That made me log."

That quote is real — it's what we said to each other when we were testing the first version. And it captured exactly what we were building toward.

Accountability works best when it's social. Not in an embarrassing way — just in the way that seeing a friend ahead of you on a leaderboard is more motivating than any push notification.

So we stripped everything back. No carbs. No fat. No meal plans. Just protein — described in plain English, processed by AI, visible to your friends in real time.

What we believe

Simple

If it takes more than 5 seconds to log a meal, people stop logging. We obsessed over every tap.

Social

The best accountability partner isn't an algorithm — it's a friend who'll chirp you for slacking.

Focused

We track protein. That's it. We'll never bloat into a full diet tracker — that's a feature, not a limitation.
