ThrowLab: Disc Golf Analyzer

Build a more consistent throw with analysis tailored to your disc, throwing style, and intended line. ThrowLab uses slow-motion video to evaluate your speed, disc angle, and release path while tracking your progress over time.

Start with a 3-day free trial.

HOW IT WORKS

1. Choose your disc
2. Select your throw style and intended line
3. Upload a trimmed, landscape slow-motion video
4. Find the disc in early flight and tap it
5. Review your analysis and Next Throw adjustment

For best results, record at 240 fps with the complete throw visible from the side.

THROW ANALYSIS

See how three key parts of your release compare with their targets:

• Speed • Disc Angle • Release Path

The gauges provide relative ratings rather than exact speed or angle measurements.

TRACK YOUR PROGRESS

See how often your Speed, Disc Angle, and Release Path reach their individual targets.

Progress is grouped by disc, intended line, and throw style, so unrelated throws are not combined. ThrowLab compares sets of five throws initially and expands to sets of 10 as your history grows.

PRACTICE SESSIONS

Throws recorded within the same practice window are grouped automatically. Open a session to review the disc, throw style, intended line, and results from every throw.

NEXT THROW

Get one clear adjustment to try next. ThrowLab identifies it based on your current analysis, recent results, and the flight characteristics of your selected disc.

COMPARE DISCS

Open Discs to manage My Bag or compare alternatives from a catalog of more than 2,400 discs.

Choose the change you want:

• Lower or higher speed • Lower or higher glide • More or less turn • Less or more fade

Each comparison includes two suggestions with manufacturer names, flight numbers, and an explanation of how each disc differs.

MORE FEATURES

• RHBH, RHFH, LHBH, and LHFH throw styles • Straight, hyzer, and anhyzer intended lines • Personal disc bag • Filterable practice history • Frame-by-frame disc tracking • On-device video processing
