Great app! Just a few suggestions

I’ve been using the Dragy app for a couple of weeks now and am loving it. It seems very accurate and is simple to use. The device itself pairs quickly and seamlessly. It really is money well spent.

I only have a few suggestions for minor improvements to the app itself.

1) I would like to be able to rearrange my personal history logs. At the moment it seems to just do it in chronological order based on when it occurred and its fixed in place there. The only thing I can do is rename the log.

2)I would love it if I could put notes on performance reports in the history tab without having to post them. Just to have them for my own records. Ex, humidity, temp, with or without launch control, boost pressure, fuel used, etc.

Overall, this app and device have been fantastic and I’m really having a lot of fun with it. I can’t wait to see some updates in the future


Great customer service, pretty good app.

This app has lots of potential and works pretty well. It measure to the single mph to the hundredth of a second and is way way cheaper than VBOX. There’s pretty limited functionality of how you can actually interact with the data it measures and I hope their short-term plans include vastly expanding that. The UI is clunky and can only be used in vertical mode. But I’m happy to be able to actually have the functionality it provides at all (with the $150 DRAGY GPS device of course) so I’m giving it four stars.


Incredible accuracy

The device is surprisingly good and the app so far has been easy to use and reliable.

As the previous reviewer suggested, the ability to add notes would be a nice enhancement.

I’ve used this at a drag strip for 5 passes and the times never varied by more than .03 sec and .2 MPH.
