Most apps guess your pressure. TruePressure calculates it — using rider weight, bike weight, tyre width, rim width, wheel size, surface and conditions. Accurate to ±1 PSI. Every time.
Not averages or guesswork. A real formula that accounts for tyre contact patch, load distribution, and surface conditions.
Install it once. Works with zero signal — garage at midnight, top of a mountain, race HQ with 500 riders destroying the WiFi.
Seven inputs. One calculation. Accurate to within 1 PSI across all 18 disciplines and tyre types.
From velodrome track (165 PSI) to MTB downhill (14 PSI) — every discipline has its own calibrated algorithm.
Add to home screen on iOS or Android. Opens like a native app, no app store required.
Clincher or tubeless — the algorithm accounts for both, including hookless rim safety warnings where relevant.
TruePressure doesn't need a tower. It needs your tyre width.
WiFi off. Phone on low signal. TruePressure doesn't care.
500 riders. One tower. Your competitors are guessing. You're calculating.
Zero bars. TruePressure doesn't need a tower. It needs your tyre width.
True Pressure When You Need it Most. Free. Offline. 18 disciplines. ±1 PSI.
