Most workout apps treat
you like a revenue line item.

01

You're renting your own workout history.

Most workout apps make you pay every month or your data is locked. Miss a payment and your years of progress are held hostage. That's not an app. That's a lease.

02

Your app doesn't respect your time in the gym.

You're between sets with 60 seconds of rest. You shouldn't be navigating three menus to find what you lifted last week. The data should be right there, already visible, when you need it.

03

You don't need a coach. You need a log.

AI programs. Suggested workouts. Social feeds. Recovery scores. If you already know your program, none of that helps you get stronger. It just slows you down.

Last Time,
Right There

Before you touch the bar, Kilo shows you exactly what you did last time on this exercise — weight, reps, sets. No scrolling back through history. No mental math. It's the first thing you see when you open an exercise.

Progress That
Makes Sense

One clean line per exercise showing your max weight or volume over time. No confusing tables. No color-coded matrices. Just the trend. Up and to the right is the goal. You'll see a plateau forming weeks before it becomes a problem.

The Heatmap
Doesn't Lie

Kilo's muscle heatmap shows your full body — front and back — color-coded by how hard each muscle group has been trained. Bright means consistent. Faded means you've been avoiding it. It makes neglect impossible to pretend you didn't notice.

Why not free?

Free apps have one business model: convert you to a subscriber or sell your data. Kilo has a different model — charge a fair price once, build a good app, and earn the $2.99/yr renewal. You're the customer, not the product.

FAQ

What happens to my data after the first year?

Your data lives on your device. It's yours regardless of whether you renew cloud storage. The $2.99/year renewal is for cloud backup and sync across devices — if you skip it, the app works fine locally. Nothing gets deleted. Nothing gets locked.

Can I use Kilo without internet?

Yes. Kilo works fully offline. Your workouts save to your device immediately. Cloud sync happens in the background when you're connected.

If you add features later, do I have to pay again?

No. App updates are free. If you buy Kilo today for $8.99, you get every feature update for the life of the app. The only thing the $2.99/year covers is cloud storage.

Is Kilo available for Android?

iOS only right now. Android is on the roadmap but not committed. Drop your email below if you want to be notified when it happens.
