Just curious what android dyno app's people have used and like.
From what I've read the newer droid devices like the HTC Evo have accelerometers so the software can make them behave similar to the G-Tech meters.I've used "Dynolicious" for the iphone (not sure if it's ported over for android but I would imagine it is, seems pretty well done).
It's interesting once you're moving, and pretty accurate in terms of measured times, but if you're looking for accurate dyno numbers, you will be hard pressed given that it's basing it off a 1/4 mile run (or shorter if you want), so that 1st+2nd gear where you fight for traction is going to hamper any true output
I imagine most apps operate the same, unless they do it from say a rolling start in specific gear, that's about the only way I see getting around the whole traction issue. Too bad I got it once track season was over
Edit: some of them also feature a skidpad function, which is pretty awesome to see, take the time to calibrate it properly and you can have some fun with it
Please do! Thanks!Ive messed around with ADyno but have been so busy that I have not dialed it in. I think I have most of the inputs. If you are interested I can post them.
I'm just amazed that there are apps to even do stuff like this. Wow!

I've read about aDyno and dinodyno or something like that but there are a few more out there than just those two.
I like angry birds. Have you played that yet?
Yep, angry birds is a great game. But how is that even remotely related to a dyno app?
A more serious question to those that have used a dyno app, whether on droid or iphone. How does it work? Is it using GPS, measuring a given distance, and then giving an estimate on hp?
Technology is amazing, as things are getting more sophisticated seemingly on a daily basis.
Those are very good results. Thanks for sharing. :thumbsup:I used it with my droid in the 1/8 mile at the track and it was about 1mph high, and within a 1/4 of a second. Pretty damn impressive if you ask me. The hp/tq probably isnt as accurate, but the times are damn close.
Interesting how many parameters there are. I guess you could really fine tune it.Here is what I have so far for aDyno inputs for a 2003 Terminator.
Legend:
* - guestimation, needs either better number or instrumented prove out at the track
** - based on same or similar car and adjusted, should be ok
*** - pretty much a fact
Other notes: The max speeds below are from memories from the track and may need some tweaking. The min speeds are calculated from the max's. If these need to be tweaked just let me know. Unfortunately with snow on the ground I can't verfiy until may (yuk). Should add also that this is for stock gearing.
