## What is TossBuddy?

You do not have a swing problem. You have a toss problem.

After thousands of lessons, one question came up more than any other: how do I hit a kick
serve? Players thought they needed a new swing, more power, more flexibility. Almost
nobody realised the obstacle was the toss, and that they had no real idea where “behind
your head” actually is.

TossBuddy puts a coach’s eye on every toss you make.

HOW IT WORKS

Mount your phone on a tripod or on your ball cart, line up on the baseline where the app
shows you, and serve as you normally would. Your iPhone camera watches the ball leave
your hand and measures where it goes, in real time, frame by frame.

Perfect, left, right or too low. You know before the ball comes down. Instant feedback right
when you serve, not in a video you watch tonight.

Kick Serve and First Serve each have their own target, because they are not the same toss.

SEE YOUR PATTERN, NOT ONE TOSS

One good toss is luck. Forty is a serve.

Toss Radar draws a whole session on a single map, measured from your head at release:
where you let go of the ball, where it peaked, and where you made contact. Each circle
shows how far that point typically sits from its own average. Tighter is more repeatable.

Switch between Path, Apex, Release and Contact to find which part of the toss is drifting,
and watch the circles shrink as it stops.

LOG WHERE THE SERVE LANDED, FROM YOUR WRIST

If you have an Apple Watch, you never walk back to the phone.

When TossBuddy sees you strike a serve, your watch taps you. Turn the crown to pick the
side, tap where the serve landed, and serve again. It takes about a second.

Your Serve Hotzone then shows every serve you have logged, so you can see whether the
toss you are proud of is actually sending the ball where you want it.

The watch is optional. Everything else works without one.

YOUR PRACTICE, KEPT

Goals, streaks and daily missions, so there is a reason to come back tomorrow. Session
history, so this week can be compared to last. Leaderboards if you want them, friends if you
want them, neither if you do not.

Record a session when you want to see it for yourself.

TOSSBUDDY PRO

Zone analysis on your Serve Hotzone, twice the practice balls before you run dry, and every toss you have ever made. Monthly or yearly, or a single Lifetime payment that never renews.

Yearly works out to less than half a one-hour lesson.

PRIVACY, PLAINLY

Your practice videos never leave your device. There is no upload path in
the app at all and no server that could receive one. Every frame is
analysed on your iPhone, using Apple's own on-device vision frameworks.

You can delete your account, and everything in it, from inside the app.

## Version history (last 3 releases)

### 1.0.5 — 2026-10-05

Toss Radar now survives a change of phone. New tosses save their ball path, and tosses restored from another phone appear on the radar instead of disappearing.

Paths and dots no longer run off the edge of the Toss Radar.

When a toss has no stored path, the radar says so rather than leaving it out.

Sign up now spells out which setting is your country and which is your serving hand, and that only your country is shown to other players.

### 1.0.3 — 2026-10-03

Left-handed players: your lane names, your daily quest and your Lounge now agree with each other. Choose your hand when you sign up, and change it any time in Profile.

Your country is now set from your phone, and can be changed once in Profile.

Leaderboards are Friends, Country and Global.

Toss Radar's Last 10 and Not Struck 10 no longer come up empty.

Your membership row shows the days you have left.

Gem totals now match between the Lounge and the Shop.

Gifted balls above your basket now land instead of being turned away.

### 1.0 — 2026-10-03

No release notes.
