I've never been able to get the DA calculator to work on the first try. always gives me an "error" or says "refreshing" and never actually shows anything. SOMETIMES, I'll open up the app and itll have the data i was looking for the last time i used it.

This app is amazing. It is a 2 and a half hour drive to the nearest proper track. I and everyone absolutely loves this app don't change a thing. Hands down best app I've ever downloaded. πŸ€ πŸ€™πŸΌπŸ€™πŸΌπŸ˜Ž

Complete trash. I paid $2.99 for the unlocks and nothing is working. I can't even get my current locations density altitude. Just keeps refreshing.

Everthing worked great until a couple of weeks ago now it just says error when I try to pull up the temperature da humidity and elevation part. That's what I use the most.

I paid to unlock all features and they are still locked. everything I can use seems to work great but I paid for something that is still locked. It would br a 5 star app if it wasnt for that.

fun in car tool to keep you tuned close. I do have a comment. When using the 60' timer and having the 0-?? speed on it only records the 0- what ever speed. it does momentarily flash, blue??? maybe as you pass through 60ft but holds no record.

The app is too bad it is just inaccurate. I'll do two 0-60 pulls back to back. First pull was a 4.2 and second pull a 6.8. If this problem was fixed it would be a great app.

Right now I'm going to have to give this app 1 star. I paid the $2.99 to have adds removed but the ads are still there I emailed the app and nothing. Pretty annoying!

Cod. Q. Jan 22, 2019

Cool app, concept that I've wanted for a long time. It randomly closes itself while I'm using it though, please fix.

The app works well, however, until the ads are removed from the $2.99 version, it only gets one star.

Doesn't come close on giving correct air temp or humidity which makes calculating the DA worthless.

Leo. A. Dec 22, 2018     

Calculators work and are easy to use, only issue is the ads, I paid to remove them but I still have them

Chr. B. Nov 30, 2018     

After paying for no ads, it doesn't work. Error all the time.
