The problem
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.
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.
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.
Built for the middle of a workout.
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.
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.
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.
Build a template for Push day, Pull day, Leg day, or whatever you run. Load it in one tap. Add, remove, or reorder exercises on the fly. Kilo saves your structure so the only thing you're thinking about in the gym is lifting.
Own it. No tricks.
No credit card required.
One-time purchase. 14-day free trial included.
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.
Common questions.
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.
Yes. Kilo works fully offline. Your workouts save to your device immediately. Cloud sync happens in the background when you're connected.
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.
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.
