Dynomaster

★★★★★ Work great on my dash mounted G-1. Only dyno ive found that doesnt have to be in a preset orientation. LOVE it! Well worth the purchase.

★★★★★ Rediculously Accurate I don't understand how this app can be so accurate without tapping into my ODBII interface!

★★★★★ Well maintained app that gets better every release.... numbers are close to real dyno figures, though e.t.s would be better with bluetooth 5hz gps.

★★★★★ Accuracy For this or any dyno app to be accurate you must take 5 minutes to enter in factors such as your car/bikes weight, frontal drag area and drag coeffient. Dont leave a 1 star rating just because your to dumb to under stand that.

★★☆☆☆ Do not waste time or your money. Completely inaccurate against other, proven products. Little to no customer support. Complete waste of money.

★★☆☆☆ The MOST INACCURATE app to measure car performance I did some tests against Racelogic Performance Box and G-Tech Fanatic Pro SS and among all apps that I tested on Android & Windows Mobile (RaceChrono, Ulysse Speedometer and Car Performance with external 10Hz GPS, Torque Pro with ELM327 OBD2 module and aDyno with built-in accelerometer), Dynomaster presented TOTALLY INNACURATE results. Support answered after receiving all the logs that "they believe it's due to the Movement Start Mode triggering too early due to accelerometer sensitivity". So I asked for refund as they stated on their website I have 30 days for it. They didn't answer since then, no single answer despite several emails. They also didn't issue corrected version of the app. It is really surprising that some people gave them 5 starts and nobody has really checked its accuracy. Despite this there are some other problems. Sometimes when I export my results to excel the whole app crashes, app uses only 1 core on multi-core CPUs, speech works very unreliable, it is also very laggy - when I press Start button it takes several seconds to start, even on powerful devices like HTC One X/Sensation or Asus Infinity Tab. So I warn you, think twice before you purchase this app.

★★☆☆☆ This is WAY off. My two bikes have 232 and 267 HP, this says they are around 500. My car has 350 HP and this says 160.1/4 miles way off 8.4 at 56 mph.
