Group fitness challenges, settled on a live board
The fitness challenge app that gets your whole crew training.
Pick the metric, set the terms, invite your circle. Everyone logs real workouts, the leaderboard moves in real time, and nobody has to chase the group chat for updates.
Free to start
No credit card
iPhone and Android
Built for group challenges
A challenge your group will actually finish.
Most group fitness challenges die in a spreadsheet by week two. kontest keeps score automatically, so the only thing your crew has to do is train.
Or join a public one
No group yet? Browse live public kontests in the Discover tab and jump into a challenge that's already running.
Positive-only scoring
kontest rewards the work with XP and never punishes a missed day, so the challenge stays fun instead of becoming homework. It's accountability that people opt back into.
Five challenge types
One workout challenge app for every kind of athlete.
Lifters, runners, walkers, and hybrid athletes can all compete in the same group — just pick the metric that fits.
Reps
Most reps logged wins.
Weight
Compete on total volume.
Distance
Track miles or kilometers.
Steps
Turn movement into a race.
Strength
Put top lifts head to head.
More than a challenge tracker
The challenge sits on top of a real training app.
A challenge only works if logging is effortless. kontest is a full workout tracker underneath, so the score always reflects real training.
01
Log in seconds
Build a lift set by set, repeat a past workout, or quick-record a session. Every log counts toward the challenge automatically.
02
Watch the feed, not the group chat
See your circle's sessions as they happen and react when someone puts in work. The trash talk writes itself.
03
Streaks and PRs feed the fire
Personal records and consistency streaks are tracked alongside the challenge, so everyone is beating their own numbers too. New to PRs? Here's what counts.
04
Steps and distance can count automatically
Connect Apple Health or Google Fit and movement-based challenges track themselves.

FAQ
Fitness challenges, answered.
What is a fitness challenge app?
A fitness challenge app lets a group compete on a shared training goal over a set period, with a leaderboard tracking everyone's progress. In kontest, a challenge is called a kontest: pick a metric like reps, weight, distance, steps, or strength, set the terms, invite your circle, and the board updates as everyone logs their training.
What kinds of workout challenges can you run?
Five types: reps (most reps logged wins), weight (total volume moved), distance (miles or kilometers), steps (daily movement), and strength (top lifts head to head). That covers lifters, runners, hybrid athletes, and step-count rivals in the same group.
Can my friends join a challenge on different phones?
Yes. kontest runs on iPhone and Android, so one group challenge can include both.
How long should a fitness challenge last?
You set the terms when you create a kontest. A week is long enough to build momentum without losing anyone; 30 days works well for habit-building challenges. Shorter and more frequent beats one marathon challenge that fizzles.
Do I need friends on kontest to start a challenge?
No. You can browse and join public kontests from the Discover tab, or start solo with logging, streaks, and personal records, then invite friends when you're ready.
Is kontest free?
Yes. kontest is free to download, with no credit card or trial timer required. Challenges, workout logging, progress tracking, and Leo the AI coach are available free today.
