The Inner ChartSecret Stats Behind Winning
The score tells you who won. The chart tells you why.
Secret Stats Behind Winning.
Not hidden. Just overlooked.
Most tennis statistics tell you what happened after the match is over. The Inner Chart shows you what was happening inside the points: the patterns, decisions and moments that decide who wins and who loses. The Inner Way of Tennis is about the 83% of a match that happens between points. The Inner Chart is built for the other 17%, when the ball is actually in play. Then it does the analysis for you: the three ways your player is winning points, where they're losing the most, and a report you can send with one tap.
The Inner Way of Tennis
The Inner Chart
Created by Randy Scott, a tennis coach with 35 years of experience.
Not more stats. The right stats.
Don't chart everything. Chart what matters. Winners, unforced errors and first-serve percentage are useful, but they don't tell the whole story. Inner Stats are the numbers beneath the score: the patterns, shots and point situations that show what is really deciding the match.
So what makes them secret?
Nothing is locked away. Inner Stats aren't secret because nobody can find them. They're secret because almost nobody charts them. The scoreboard shows who won. A box score counts winners and errors. The numbers that explain why points are won and lost, like who controls the first four shots, what happens on the shot after the serve, and how often a player is fighting the match instead of flowing with it, get overlooked. The Inner Chart brings them into the open, point by point.
Traditional tennis stats
- Winners and unforced errors
- First-serve percentage
- Aces and double faults
- Points won
Inner Stats
- The first four shots, and who wins the short points
- Serve +1 and return +1: what happens on the shot right after the serve and the return
- Serve and return patterns: placement, big first serves neutralized, second serves attacked
- Rally length: which rallies your player wins and which they lose
- Why each point ended: forced or unforced, neutral or offensive, and off which shot
- Competitive moments: momentum runs and the points that swing a game
The Inner Chart was created to make meaningful match analysis simple enough to use point by point, and powerful enough to reveal the patterns behind winning and losing. Other apps compete on how many numbers they track. The Inner Chart tracks fewer, better ones.
Less noise. Greater awareness. A clearer picture of what's really happening on the court.
Created From 35 Years of Coaching Experience
Inner Chart was created by an experienced professional tennis coach with 35 years of experience working with players at every level—from beginners and recreational players to world-ranked junior and senior players competing on the USTA, ITF, WTA, and ATP tours.
Over the decades, I tried many different tennis apps and charting systems. While they all had useful features, I couldn't find one that charted what I believed really mattered—or allowed me to capture it with the level of detail and simplicity I wanted.
So I created Inner Chart.
It was built from the perspective of a coach who has spent decades watching, teaching, analyzing, and developing players. But Inner Chart isn't just for coaches. It's designed to give coaches, players, and parents a clearer picture of what is actually happening on the court and where meaningful development can take place.
Simple when you want it. Deep when you need it.
Simple mode
Tap the rally length and how each point ended. That's it. After the match you get the three ways your player won points, where they lost the most, and what to work on next. No tennis-stats background needed.
Full mode
Add serve placement, Serve +1 and Return +1, the First Four Advantage, court position, and the Inner Way marks for attitude and awareness. The app finds the patterns behind winning and losing, like which serve and first shot win the most points.
Use it during the match
Coaching is now allowed during play at some events. The Inner Chart updates its insights with every point, so players, parents and coaches can see what's working and what isn't while the match is still going. Then they can use it in the moments coaching is permitted, at a changeover or between sets. Check each event's rules for when coaching is allowed.
🌐 In your language
Available in English, 日本語 (Japanese), ไทย (Thai) and 中文 (Chinese). Switch languages any time with one tap, in the app and on this page. Shot names like Forehand and Backhand stay in English, the way players already say them.
Every other tennis app picks one side of a tradeoff.
Live tools keep things fast but shallow. Deep tools capture everything but only after the match is over. Nothing else does both.
Live & shallow
Built for courtside use. A winner is a winner, an error is an error — no record of what produced it.
Deep & after the fact
Extraordinary shot-by-shot depth, the gold standard in tennis analytics — but a manual, post-match video review exercise for researchers, not something you'd run during a match.
Live & deep
That same shot-construction depth, operated with one thumb, live, while the ball's still in play — then turned into a game plan the moment the match ends.
Apps built for courtside use, like Top Tennis Tracker and ProTracker, are fast to tap but shallow by design: a winner is a winner and an error is an error, with no record of what actually produced it. The Match Charting Project, the closest thing tennis analytics has to true shot-by-shot depth, captures that construction in extraordinary detail — but it's a manual, post-match video-review exercise built for stats researchers, not something anyone could run while actually watching a match. The Inner Chart is the only one built to do both at once: the depth of a full charting system, operated with one thumb, live, while the match is still being played.
Charted for the why, not just the what.
Every ending in The Inner Chart carries its cause. These are real categories from the app, tapped mid-point — not a scorecard filled in afterward.
An unforced error is marked neutral or offensive, not just logged as a mistake, because missing while under no pressure and missing while going for too much call for two different fixes. A forced error records which shot produced it, so you know whether it's the serve, the return, or the volley that's actually winning points. A second-serve return that got attacked is marked by whether the returner followed it in, and a big first serve is marked not just as a point won, but as neutralized when the returner got it back in play. None of it is decoration — it's the difference between knowing the score and knowing what to work on before the next match.
The match ends. Your game plan is already waiting.
Most apps hand you a pile of numbers and leave the hard part to you. The Inner Chart captures what you see in the moment, reads the data for you, and puts the answer in a form you can send to your player before they've left the court.
Catch the thought before the next point.
Tap Note on the scoreboard and jot a line — or speak it with your keyboard's microphone. Every note is stamped with the set, game and score it was written at, so "rushing between points" is tied to exactly when it happened. Notes sit in the point log, the stats and the shared report, right next to the numbers they explain.
How your player wins points — and where they're losing them.
The Inner Chart analyzes every point and names the three ways your player is winning points: hitting winners, forcing errors, outlasting the opponent, or free points on serve, with the shot and rally length behind each. Then it ranks where they're losing the most — unforced errors, the second serve, a rally length they can't win — and gives each one a clear number to track next time. One match or a whole season, it works the same way.
Send the whole match as one picture.
One tap turns the stats into a clean image report — scoreboard, insights, key metrics, every table and your notes, laid out just like the app. Text it to your player, email it to a parent, or drop it in the team chat. No spreadsheets to explain, nothing to download or install on their end.
Make it yours.
No two coaches track the same thing for every player. Add your own categories for whatever matters to your player's game plan — a tactical cue, a shot pattern, anything at all — and they flow straight into the same stats and the same exportable spreadsheet as everything else. None of the other apps in this space let you do that; they lock you into a fixed list someone else decided mattered.
“True progress doesn't begin on the outside. It begins within.”
Chart the point. See the pattern. Change the game.
The reasons behind a point matter as much as the point itself. That's the whole premise of this show. Now it's a tool you can use while you watch, and it tells you what it all means when the match is over.
Play from the inside out.
