Shared mission

Why we do this

The hardest part of fitness isn't the workout.

It's showing up - again, on the days you don't feel like it. Fitness doesn't have a knowledge problem; every program you'll ever need already exists. It has a motivation problem. And the strongest fix humans have ever found for motivation isn't an algorithm or a streak badge. It's other people.

That's the gap JustGains exists to close. We're building the best fitness app ever made - and we believe the way to get there is to put people together: friends who see you show up, programs you run side by side, a gym that fits in your pocket and still feels like a gym. Working out together is the heart of it, and we make it possible in every way we can - starting with keeping it free, so nothing stands between you and the people you train with.

And we think great software can come from anywhere. JustGains is the proof: two people, two continents, six time zones - outshipping companies a hundred times our size, one commit at a time.

Together beats alone

Nobody quits fitness because they ran out of exercises - they quit because they were doing it alone. Every feature we build exists to put people together: shared programs, friends who see you show up, workouts you run side by side. And it's all free, because nothing should ever stand between you and the people you train with.

Your data is yours

Every rep you log belongs to you. Export it anytime, take it anywhere. If we ever stop earning your trust, you leave with your whole history - no hostage-taking, no dark patterns, no begging support for a download link.

Curated, not scraped

Every program on the Discover page has been reviewed in depth - by a human, not an algorithm. We work directly with creators' content so it shows up in JustGains better than it does anywhere else, including the places it came from.

The founders

Meet the humans.

One runs experiments between sets and meals. The other ships code between dance breaks and zombie marathons. Six time zones apart, they somehow make one very good gym.

Field notes · JG-01

Reps. Research. Really good food.

His favorite questions are usually: How does it work, how can it work better, and what are we eating after?

Food

James has spent his career in software - C#, cloud, security - and his mornings under a barbell. He started JustGains with one conviction: the best fitness app ever made wouldn't just track your workouts - it would keep you showing up, by putting the people you train with right beside you.

He runs Just Super Human LLC and ships to JustGains pretty much every day. Ask him about nutrition coaching, jump rope, or why the best training partner is the one who knows you skipped yesterday.

Dance like the zombies are gaining.

Her off-duty universe runs on dance breaks, zombie stories, and the kind of energy a two-person startup needs.

Dance
Zombies

Glory taught herself to code in Malawi, earned her first $100 freelancing in 2022, and never slowed down. Today she builds some of the most ambitious features in JustGains - the kind other apps put whole teams on.

She also curates everything you see on the Discover page. Every program there has been through her hands - reviewed in depth, structured properly, checked against the creator's original work - so that creators' content is represented in JustGains better than anywhere else.

She is living proof of what we believe: talent is everywhere, opportunity should be too. The best software can be built from anywhere - including a home office in the Warm Heart of Africa.

…and the dog.

His name is Bro - Bro Bro on formal occasions, Lil' Bro to close friends. Chief Morale Officer since day one: he supervises every garage-gym session, inspects each plate before it's loaded, and enforces rest periods by standing on your chest. Perfect attendance, zero missed leg days - and he's got four of them.

It took a village

Two names on the door. A crowd behind it.

JustGains exists because a handful of people believed in it before there was anything to believe in - no users, no revenue, just a conviction that this could be the best fitness app ever made: one that keeps people training by keeping them together. These are the people who made the leap with us.

Founding design

Uliana Potopova

Before JustGains had a single user, it had Uliana's mockups. She spent the entire first year designing the app screen by screen, state by state - turning a rough idea into something that looked like it deserved to exist. Much of what you see in the app today still traces back to her original designs.

Early believers

Our first investors weren't funds - they were friends and family who wrote checks on nothing but trust. When JustGains was a pitch and a prototype, they bet on the people instead of the numbers.

And to our friends on X - who tested the rough builds, called out the rough edges, and cheered every changelog - thank you. You shaped this app as much as any commit did.

Come lift with us.

Everything you've read about is in the app - free. If it makes your training better, bring a friend. That's our whole marketing department - and the whole point.
