PerfExpert - Car Onboard Dyno for Android
Not easy to put in parameters there should be a preset parameter for the cars listed. Have a 15 genesis 3.8 this app says I'm running 170 hp....
This app has saved me loads of cash, results are spot on when using accurate car specs, very satisfied!
Tried this app with a few different cars that have been on a real dyno and figures have been totally out. How do i go about getting a refund as I've only had the app a day
AWESOME APP !!! It does what is says. Tried on Renault 2.2 dci, and Toyota Avensis Verso 2.0 d4d, and on both cars everything was in specs. It's amazing how this thing is so accurate. I would like to rate this app 10 stars, but I can't find such option :) Thank you PerfExpert team for this superb application. Cheers

gave different results on the same car every time i tested it. the same car, the same road,the same gear and acceleration and weather, difference in hp mainly whiles torque was more or less ok
we compare perfexper by real dyno and difference was +-3hp... amazing app
at first when i ran it multiple times it gave the same reading give or take 1-3 bhp so i took that as being quite accurate, at least as a comparison tool to look at the effect of any upgrades even if it wasnt exactly correct. i tested it 2 days back and ran 3 checks under the same conditions and got 3 different readings which were all way different to a month back with no changes in between. has an update messed it up?
Very good app indeed.
Originally gave it one star because it didn't have my car, then the developer contacted me and had it put in, still missing several cars, including every Acura except mine, so it might not be worth it for someone with an Integra, but I don't tally know how it works, so...yeah, get this app.
FAIRLY ACCURATE providing you input the correct data prior to testing in vehicle.
This is the best app that I've found to measure the stats on your car and keep track of performance improvements.
Takes a while to fill everything out i can put car on a real dyno quicker. Much preffered older version. Im now going to uninstall app by everyone. Good luck.
Even on an uneven road I got really close to what the specs should be, great app
Still testing it out. So far so good.
2 things need improvement: ; tires sizes for motorcycles are not available so you must find equivalent tire heights for sizes; e.g. 180/55/18 == 245/35/19 ; must do metric/empirical conversions yourself.
It pains me to say its worth 20 bucks but it is.
Not great as it looks. Adding car info is pain. Interface and calibration horrible. 8.9euro is way too much for it.
Great app.The best way to use is in third gear I had trouble getting accuracy in second.Take time in getting info on car gear ratio etc and it works well
HI GUYS IV BEEN USING SOFTWARE WITH NEW PLATFORM AND REALLY DONT LIKE IT...... OW CAN I HAVE THE ORIGINAL VERSION BACK AS IV FOUND THAT THE NEWER VERSION ISNT REALLY VERY CLOSE TO ACCURATE. SO CAN I HAVE OLDER VERSION BACK AS THIS WAS FAR BETTER. CHEERS SHANE
Great app. Accurate. Looking forward to upgrade for calculating stats for electric vehicles with single speed transmissions.
Fun to mess around with not too far off suprisingly!!!!
Very acurate used on Porsche 911 tuning!
Still testing it out. So far so good.
Found it to work getting specs higher than what it's sposedly should have for my set up. 350whp 360wtq these are ethanol #s not the pump gas that I'm running but all in all a fun app. Maybe I'm just a better tuner than I think I am.
Very accurate dyno and timed run
It measures very accurately
Graph won't open
Measured 4 different cars close to same conditions on dynojet and this app... only a few HP/ft lbs off.
Dynoed my M135i at 321, 316 and 326 hp (at the engine) which is very close to spec. I am impressed!

So far is awesome. Let me get some more runs
At first look its promising app... i hope i am not wrong! ;)

A bit difficult at first, maybe also because I drive an automatic. But the results are spot on, very impressive for "only" an app compared to a rolling road.
Best I've used so far. Seems consistent with stock car specs
Had my car dynoed and hp was 2 hp in difference from this app.

I've tried several times to see how accurate it is, and I know my doesn't make almost a 1000hp.... way off. Paid for an app to give a false reading.
