Anybody tried one of those dyno app's wich is out for iphone and android phones?

Would be interesting if someone could compare the results from a Dyno app with the results from a real dyno run.

I'm getting a new android phone next week and will be getting a dyno app. Since i don't have a dyno anywhere in the area i live, i have no way of checking if the results can be use for more than entertainment.

 

I have aDyno for Android, but I don't have a mount for my phone yet so I haven't really tried it. Seems promising though. Drawing comparisons to other dynos doesn't mean much. It should be good for comparing different cars or mods, you have to be consistent with your testing procedures like always using the same stretch of road, same fuel level, etc.
