Comments on PerfExpert - Car Dyno HP Test for Android

★★★★★ James Nichols · Jul 28, 2020

Tried this app because of the developers efforts. Wanted to see gearing and rpm calculation applied to an HP app. So far so good. The option for entering weather manually is good for stopping extra weather updates.

★★★★★ Gabriel Yeung · Apr 13, 2025

This app is pretty cool. For the several 1-star ratings or all the ratings that say this app does not work and the calibration does not work, you simply aren't doing it right; user error, as the developer keeps saying. I did the calibration of my phone sensors once, put in all my car's parameters according to Automobile Catalog, and did one Dino test. That first test seemed pretty accurate. My car is rated for 265 HP stock, and it read about 281 HP, which makes sense given the mods I have done.

★★★★★ Austin Germs · Feb 29, 2016

Really accurate Even on an uneven road I got really close to what the specs should be, great app

★★☆☆☆ Danny Sebahar · Jul 17, 2023

My car, a 2003 BMW 325i doesn't show up even though every other BMW from that year does. And when you do the Dino you can't have an Automatic transmission. My car is automatic, but you can select the gears it is in. I'm confused about what the gear minimum RPM us and the starting speed even though you start from a standstill. And my biggest confusion is: based on the formula for HP (HP=torque*rpm/5252) HP and Torque will always be the same at 5252 RPM, but the graphs never cross at 5252 RPM

★☆☆☆☆ J Cole · Feb 15, 2019

Keeps won't go past calibration mode. Literally did the same 9 steps 4 times. Wish I didn't waste $10 on it.

★★☆☆☆ Sean Sean · Oct 9, 2016

Gave different results on the same car every time I tested it. The same car, the same road, the same gear and acceleration and weather, difference in hp mainly whiles torque was more or less ok
