UstaDyno is for drivers who care how fast their car really is. It times your runs from GPS and your phone's motion sensors, and adds engine data when you connect an OBD2 adapter.
Speed, gear, rpm and the power band on one screen while you drive. Not ready to drive yet? Try it with the built-in demo car.
Every split is timed and checked for road slope and GPS quality, so a result you share is one you can stand behind.
Compare stock against Stage 1, or any two setups, with averaged curves and real statistics instead of one lucky run.
An AI score for every run, with reasons and what to do next, such as letting a heat-soaked intake cool before the next pull. Export it all as a PDF.
Bring a CSV, MSL or Excel log from another logger, match the columns, and get a full dyno sheet from it.
Your garage. Every car with its photo, setup and personal bests.
Share your runs. Story cards and PDF reports, with your shop's logo.
Crank power, wheel power and torque curves, corrected to SAE J1349, with room to read every detail. Ideal for tuning shops showing results to customers.
GPS mode works on any phone. Plug in UstaOBD to log RPM, intake air temperature and barometric pressure with every run and get estimated horsepower and torque.
GPS-only mode times 0–100, 100–200 and the quarter mile on any phone.
Connect UstaOBD to log RPM, intake air temperature and barometric pressure with each run.
Estimated power and torque curves, corrected to SAE J1349 standard conditions.
Every run gets a validity score that accounts for slope, weather and signal quality.
Post clean result cards to compare with friends and your car club.
GPS Doppler speed combined with your phone's motion sensors for precise timing.
