About
ThrowLab brings flight analysis, distance measurement, and practice history together on your iPhone. See estimated throw speed, disc angle, and early-flight path, then compare each throw with your recent results.
Track your longest throws, explore trends, and save speed and distance records across your bag.
Start with 5 free video analyses and 5 free saved distance measurements, counted separately. ThrowLab Pro unlocks unlimited access to both.
FLIGHT ANALYSIS
Import a throw video, find the disc frame by frame, and analyze its early flight.
• Estimated speed in mph or km/h
• Disc angle in degrees: Up, Down, or Flat
• Early-flight path in degrees: upward or downward
• Differences from your recent averages
• Saved ranges showing your lowest and highest readings, with a marker for the current throw
• Forehand, backhand, right-handed, and left-handed throws
• Straight, Hyzer, and Anhyzer intended-line selections
Disc angle estimates visible rim tilt from the camera’s viewpoint. Readings from −8° through +8° are labeled Flat. Intended lines describe your planned throw and group comparisons.
Comparisons use the same disc, throw style, and intended line. Saved ranges describe variation across throws, not measurement accuracy.
DISTANCE TRACKING
Measure the estimated straight-line distance from your throwing position to your disc’s final resting position, including skips and rolls.
• Feet and meters
• Estimated elevation change
• Local wind estimates from Apple Weather when available
• Average and farthest qualifying distances by disc
TRENDS AND MILESTONES
Explore speed, disc angle, early-flight path, and distance trends. Filter by disc, throw style, and intended line, and choose how many recent throws to display. Tap a chart point to see its reading.
View your farthest qualifying throws and fastest saved flight readings by disc and throw combination, with trophy cards highlighting your records.
Share full-page images of Trends and Milestones.
PRACTICE SESSIONS
Flight analyses and distance measurements are grouped into practice sessions. Review throws, filter history, and sort by distance.
Delete individual throws or entire sessions. Comparisons, averages, and records update using the remaining eligible throws.
YOUR BAG AND DISC COMPARISON
Build your bag from a searchable catalog with auto-filled flight ratings.
Compare up to four discs with color-coded estimated flight paths. Adjust arm power and throw style to explore their differences.
PRIVACY AND ACCURACY
Throw videos are processed on your iPhone. Distance tracking requires camera access; measurement camera frames are not saved or uploaded. Location supports distance measurement and local weather requests.
Flight readings, distance, elevation, and wind are estimates. Flight readings describe early flight rather than the exact instant of release. Camera placement, perspective, lighting, motion blur, and video quality affect results. Use consistent camera placement when comparing throws.
Disc comparison paths use flight ratings, not recordings of your throws.
Throw safely and stay aware of your surroundings.
