Every stat starts
as a real point.

No clipboard, no guesswork, no leaderboard. Two taps a point at the fence, and TierBreak turns a junior tennis match into serve percentages, break points, and big points; switch on a capture step and it measures error recovery too. All of it against your athlete's own past.

Two taps buys the whole floor

The capture floor is the serve, then who won the point. That alone is enough: you walk to the car with first-serve percentage, aces and double faults, break points won and saved, and serve and return points won. Miss a game handing out sandwiches? Track what you can, even set scores only. The trends need matches, not perfection, and TierBreak is built for real fences, not lab conditions.

The score already knows the big points

A break point at 4-5 in the third set feels different from one at 0-40 in the first game, but both are break points, and the score knows it before the point is played. TierBreak labels every point automatically from the score alone: break point, game point, set point, match point. Nobody has to decide the rules in advance or remember them under pressure, so the definition never drifts and one season stays comparable to the next.

The big-points view then puts those points beside your athlete's own baseline from ordinary points and names where the numbers sit. It does not diagnose, and it never ranks your child against anyone else's.

The stat nobody keeps by hand

How often does your athlete win the very next point after one of their errors? How long does a bad patch run before it stops? Easy to describe, tedious to keep by hand, so TierBreak computes it from tracked points once the how-it-ended capture step is on. Over a season it often shows that the main challenge is not the big point itself. It is the 30 seconds afterward. That turns "be tougher" into a specific reset a practice can rehearse, and the same numbers show whether it is working.

Sample sizes, or silence

A 40 percent rate on 10 pressure points tells a different story than the same rate on 60. So the sample size sits beside every number, a thin group is dimmed rather than presented as a finding, and the post-match insight will not speak at all until it has enough tracked points behind it. If a capture step is off, that field stays blank; TierBreak never guesses a value and never counts "not tracked" as though it happened. Honest silence is a feature, not a gap.

One metric across a season: this athlete, against their own earlier self.

Depth is a switch, not a second job

Every extra capture step is its own toggle and starts off: serve placement, rally length, how the point ended, the final shot, court position. Each buys a specific answer, like which shot is paying and which is leaking, or whether coming forward pays. Add a step on a day you can keep up, and step down mid-match on a day you can't. The return wing costs nothing extra at all; the wing tap simply replaces the serve tap.

Returns by wing and court side. Usually the first thing a coach is actually working on.

Your coach reads the same numbers

Connect a coach and they read the same week and the same numbers, under scopes you choose, so the next lesson starts from evidence instead of two different memories of the match. The athlete keeps what is theirs: written reflections stay private unless they decide, entry by entry, to share. The numbers are the family's to discuss; the words stay the athlete's.
