Disc golf throw analysis on your phone

Throw. Review. Improve.

DiscLab films every throw from the side and calls out your release speed as soon as the disc leaves your hand. No smart disc, no radar: just your phone and the discs already in your bag.

How it works

More throws. Less phone checking.

Set up once and work through your bag. DiscLab records, measures and speaks, so your attention stays on the next throw.

1. Set your phone to the side

About 5 m (16 ft) away at chest height, with your whole body and your release in the picture. A tripod is easiest. Throw into a net or out into a field, indoors or out.

2. Throw and hear your speed

Each throw is detected, saved with its video, and called out loud. No tapping record between throws. Measurements depend on your phone, the light and a clear view of your release.

3. See what changed

Throw a few with your usual form, then a few with one change. Compare the numbers across the set, replay the throws behind them, and keep what you can repeat.

DiscLab's live view mid-throw, with the session's release speeds listed beside it: 46, 41, 38 and 39 mph. — Each throw joins the list with its speed, video and simulated flight.

A saved throw replayed side by side with a reference throw, both paused at full reachback. — Replay a throw beside a reference throw, synced from reachback to follow-through.

Beyond the speed

Your discs. Your flights. Your history.

My discs: photographed discs grouped as distance and fairway drivers, with flight numbers and throw counts. — **My discs** Photograph your discs once. Show one to the camera before a throw and DiscLab knows which disc you threw.

A bag's estimated flights: each disc's path drawn from the tee, labelled with its photo. — **Bags** Compare how the discs in a bag fly, how stable they are, and how far your throws with them land.

Stats and progress: release speed and measured distance by session over six weeks, both trending up. — **Stats & progress** Every throw syncs to your account. Mark the tee in a field, point the camera at each disc where it landed, and DiscLab measures how far it went.

Flight simulator: a bird's-eye flight path over distance rings, with the disc's speed, glide, turn and fade. — **Flight simulator** Explore over 1,600 discs, shape flights, and try new lines. Try it in your browser.

Before you head to the field

Your phone. Your discs. Your progress.

Do I need a smart disc?

No. DiscLab measures from your phone's camera. Throw the discs already in your bag, with no sensors to attach or special disc to buy.

What happens to my videos?

They stay on your phone. A video goes online only when you choose to upload and share it, and you can take it down at any time.

When can I try DiscLab?

DiscLab is in beta on Android 12 or later and iPhone with iOS 17 or later. Ask for a place in the Beta program forum; you can post there without the app.
