Tell it your miss
A few questions about your ball flight, your clubs and how you practise. Two minutes, no account.
A golf coach for iPhone
Your miss. One fix. Proof in your ball flight.
Tell Tenball what your ball does. Get one likely cause and one drill. Hit 10 balls at the range and watch your own chart.
7-day free trial. No account needed. Android after iPhone.
Start from the miss
What does your ball do?
Tenball doesn't start with a swing video or a list of 45 faults. It starts with the shot you hit most. Pick yours: see what it looks like, why it happens, and the first thing to try.
I swing
Slice
Starts straight, then curves away to the right.
Try this at your next session
Stop aiming left to allow for it. It makes the swing cut across the ball even more, and the curve grows. Aim straight at the target and watch what the ball does.
In the app, this becomes your plan: one likely cause, one drill, and a 10-ball count that tells you if it's working.
The guide from the app
How it works
One thing at a time. Checked by the ball.
02
Get one fix
The most likely cause, in plain words. One drill with three cues, the reps to do, and what the ball should do if it works.
03
Hit 10, log 10
After your drill reps, hit 10 balls. Two taps each: where it started, and whether it curved. One-handed, big buttons, works offline.
The ball is the scoreboard
No swing score out of 100. Just your misses.
Every session adds one number: how many of your 10 balls did the thing you're trying to stop. You set the target. The chart shows whether the fix is working.
- Below your target two sessions in a row: that miss is beaten, and the next step unlocks.
- Not moving after three sessions: Tenball says so and moves you to the next likely cause.
- Your numbers stay on your iPhone.

The miss ladder
Beat one miss, then the next.
When your first miss is under control, Tenball moves you up a rung. Same loop every time: one fix, 10 balls, your chart.
1
Your miss
The slice, hook, push or pull you picked.
2
Contact
Fewer fat and thin shots.
3
Distance
Solid strikes, a club further.
4
Short game
Chips and pitches that stop close.
5
Your goal
Break 100, break 90, or the goal you set.
Film your swing
See it in slow motion. Keep it to yourself.
Stand your phone on the ground or a stand, film a swing, and watch it back at half or quarter speed. Anywhere you can make a full swing: range, garden, garage.
- Videos stay on your iPhone. They are never uploaded.
- Simple setup: hip height if you can, whole body, club and ball in view.
- Delete everything any time, in the app.
Honest by design
What we won't promise you.
Golf apps love big claims. Tenball only shows you one kind of proof: your own ball flight.
No instant fixes
A drill takes sessions, not seconds. The chart tells you honestly how it's going.
No handicap promises
We can't know your next score. We can help you hit fewer of the shot you hate.
No made-up proof
No invented reviews or user counts. When the app has something to prove, it proves it with your numbers.
Questions
Before your next range session
Do I need a launch monitor or any gadget?
No. You need your eyes, your phone and a bucket of balls. You log where each ball started and whether it curved, in two taps.
I practise on a simulator or a net. Does it work?
Yes. Tell the app where you practise and it adjusts the plan. On a simulator you can log what the screen shows.
What does it cost?
Tenball is a subscription with a 7-day free trial. You'll see the prices in the app before you start, and you can cancel any time in your App Store settings.
Where does my data go?
Your answers, sessions and videos stay on your iPhone. We count how the app is used without your name or answers. The full detail is in our privacy policy.
I'm left-handed.
Directions, cues and ball-flight pictures flip for you. Pick your hand in the first questions.
Can I ask a real person?
Yes. "Talk to the coach team" in the app reaches us directly, and we reply there.
