The Problem

Every weekend, millions of rec games end with the same argument:
"It was out." "No way, that was in."
No replay. No proof. Just bruised egos and broken doubles partnerships.

How it Works

Three steps. Three seconds.

01 · MOUNT

Set up your phone

Mount your phone courtside. Aim at the baseline or sideline that always causes drama.

02 · RECORD

Play your game

Overturned records continuously at 120fps. Memory-safe circular buffer — no storage anxiety.

03 · REVIEW

Scrub the call

Tap the line, scrub frame by frame, save and share the verdict. End of argument.

FAQ

The honest answers.

How much does it cost?
Free at launch. We're focused on getting players using it before we worry about monetization.
What phone do I need?
Any modern smartphone that supports 120fps slow-motion recording. We've tested heavily on Pixel 7 Pro (Android) and iPhone 12+ (iOS). The faster your camera, the cleaner the call.
Is it just for pickleball?
No — Overturned ships with pickleball and tennis support out of the box. Volleyball, badminton, and soccer-goal-line modes are on the roadmap. Switch sports inside the app.
Where does my video go?
Nowhere unless you share it. Recordings live on your phone in a circular buffer that overwrites old footage automatically. Zero cloud upload, zero analytics on your video, zero access to your camera roll.
Can I share clips?
Yes — tap share to export the disputed frame or full rally with the Overturned watermark. Perfect for ending the group-chat argument permanently.
About

The line judge every court has been missing. Built by a player, for the players.

The Story

Overturned started on a rec court, after one too many arguments that ended with "you'll never convince me." It's an indie-built instant replay app for pickleball, tennis, and any sport where lines matter. Frame-by-frame review, no cloud upload, no subscription — just proof when you need it. iOS and Android, 2026.
