Track
Every run, walk and ride. Down to the kilometre.
Start, go, finish. Kin draws your route, counts your steps all day, and tells you what the effort was worth.
- Clean routes. GPS jitter is filtered out, so waiting at a crossing doesn’t pile up distance.
- Best efforts. Your fastest 1K, 5K and 10K inside every activity, with a gold PR the day you beat one.
- Splits, pace and climb. Every kilometre laid out, the quickest one lit.
Compete
Race your friends, not strangers.
A leaderboard means more when you know everyone on it. Kin ranks you against the people you actually train with.
- Weekly challenges. Today, this week, this month: one board, the person to catch right at the top.
- Segments. Mark the hill, the sprint, the loop by the lake. Every pass is timed, and friends race you for the top spot.
- Head-to-head. Swipe through the last two weeks against any friend, one day at a time.
Share
Cards worth posting.
Every activity gets a card made to be shared: your route drawn clean, the distance big, the record in gold.
- Month and year in review. Your totals, your best day, and every day of the period as a calendar.
- Badges that mean something. Struck medals from bronze to platinum, from a first 5K to a marathon.
Run Together
Start a shared run with your crew. Everyone records on their own phone; Kin adds up the distance and shows who’s out right now.
Plan it together
Put a run, ride or gym session on the calendar and invite friends. Everyone gets the same reminder before it starts.
Feed and kudos
Your friends’ runs with their routes and records, photos and videos. Give kudos, keep each other going.

Questions, answered
Is Kin free?
Yes. Kin is free to download and every tracking, challenge and social feature is free, along with the Couch to 5K plan. An optional Premium removes ads and adds the 10K and half marathon plans, extra share-card themes, and CSV and GPX export.
Do I need an account?
No. Kin works fully without one, and keeps your history on your phone. Sign in only when you want friends, challenges and the feed.
Is there an iPhone app?
Not yet. Kin is on Google Play today, and the iPhone app is being built now.
Who can see my routes?
Only the people you share them with. A route leaves your phone when you post that activity, create a segment, or turn on Beacon for a run. You can stop sharing route maps at any time in Settings.
How many languages does Kin speak?
25, from Arabic to Vietnamese.
How do I delete my account?
From inside the app, in Settings. Everything stored on the server is removed with it. See exactly what is deleted.
