The users that are saying it does not work are not using it right. Flat road, 100% accurate car data and weight/fuel, WOT in correct gear before recording start speed, do 3 runs same way and ending at the same RPM and releasing throttle (don't shift up) will give you accurate results. Don't do it on inclines or declines. Best customer support, the owner is direct and straight forward and only wants to help you get the best results. I'm testing it in my BMW M235i.

Best for android Keep up the good work! Really good app, but keep in mind that proper weight and specs of your car, good phone mounting and good road are essential for a precise measurement. Also, repairman is simply wrong as the s2 Dino uses mkg for torque and NOT ft/lbs.Hence, his misunderstanding about where hp and tq should intersect ;)
★★★★★
This app has saved me loads of cash, results are spot on when using accurate car specs, very satisfied!
★★☆☆☆
Had high hope for this app. It is very detailed and the configuration for you car is very technical and specific which I like alot. After I went through the calibration and car set up I could not Dino my car even on a smooth road because my sport springs are to stiff and the app gives an error message because of this. I will not change my race suspension for this to work properly. I will request a refund. It is a good app for a Lincoln Town Car.
★★☆☆☆
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
★★☆☆☆
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
