Elevation for DA is nowhere near correct...I live at 6800 ft elevation and it tells me I’m 2580 with a DA of 4300 ft.... Absolutely wasted 2 dollars

DA feature broken

Cnstman on

The DA by location feature has been broken for months. Useless app anymore.

App is useless without DA function

Mchell89764 on

I bought this app specifically for the DA function. This does not work which makes the app useless. The developer states issues with weather station. I’ll take my money back now. I would give it ZERO stars if I could......

Needs an update for new screen size

Cool, just a few tweaks needed IMO

ModerateGuy991 on

Please allow the back arrow to take you back to the particular make of car you are currently viewing. And of course if you could integrate quarter-mile videos that would absolutely be insane. Thanks!


Lsxwellzy on

When I click on the density section it will give me the DA but then freezes up an won't let me do it by the drag strip. Won't even let me click on other features. When the app was working properly I loved it. But now I'm going to the track not knowing what my DA is....

Since the iOS8 update the DA calculator freezes the APP. Loved it before. Please fix this issue!!!

Worth it!!

I was hesitant at first for 1.99 but this app has so manny useful features! I'm so pumped to browse threw so many different ACTUAL cars, look at their mods and times, and to compare my own car and driving skills! I think a nice improvement for this app would be a way to make profiles to communicate enthusiast to enthusiast about different mods and results.

Needs update

cjh2000us on

I have an iPhone 5 and the screen is not formatted for larger screen. Great app, just needs some tweaks.

Useful, but missing a key feature

Hiren1 on

This is very useful for finding your DAs. The key lacking feature is saving your track and date info, it's very annoying having to re enter the info every time when trying to find a DA in the past.
