ThrillGauge asks a private question before the roller-coaster queue

Field notes

ThrillGauge uses height, weight, and optional body measurements to compare a visitor with riders who have submitted similar reports. Its displayed example for Jurassic World VelociCoaster includes a score of 8.2, a 76% confidence level, a 7.4–8.7 range, and 24 comparable reports. The page says users can report restraint type and fit afterward, while measurements and individual ride histories remain private. The project currently describes its iPhone version as a private TestFlight beta.
