ScanMaster for ELM327

Tried a few free aps & ScanMaster lite was the fastest and most consistent. UI is good on phone - only negative is that there seems to be a few minor scaling/positioning issues on tablet. Not tried the pro features yet - purchased out of appreciation of the lite version - thank you.

Straight forward user friendly. It works no fancy crap. Tried a few apps that did not connect with ease, whereas this one connected via blue tooth on my Samsung Android without any problem at all

Bought the pro version. As far as ease of use this product does well. But it has shortcomings that make it not much more than a toy. I set up some parameters to graph but when I went to graph. Only two parameters show up the rpm and vehicle speed even though I didn't select them. Every time I re enter the data stream view my selections are reset. You can only set things up when you are connected to the car. No way to save your setup or any data you collect. Quite amateurish.

But it's very bad at graphs. cannot save data. have to choose the values each and every time you open the app. Cannot customize or configure anything while not connected to vehicle. Have much potential but not fulfilled. Is good for reading & clearing DTC's, but that many apps can do.

this is the only software that worked on my generic elm327 obd scanner for my nissan altima. it accurately detected the P0100 MAF sensor error. my car starts then dies after 3 sec.

Love this app , it shows me all the codes (when you buy the app) thought it wasn't gonna be worth it. But i was wrong, it was an amazing app buy the full version it's worth it.

It has worked with only one vehicle. Can not communicate with vehicle pops up when I try it in my other vehicle. I've sent the trouble logs but have not received a reply.

I have been using the ScanMaster-ELM since 2012 flawlessly. Now I have just downloaded the app for my android and hope to use it on the move. The Company has an excellent backup support.

15 Jan 17-Is it a secret what this app costs to make it do much of anything? 16 Jan 17-I have to get too close to purchasing to see it and don't want to risk it. Can't understand website. What's USD price? 17 Jan 17-Thanks for the follow up with the $4.20 USD price.

Will not communicate with the obd unit, so a bit useless really.

This is bad, really bad. Data streams doesn't work it errors out on all the functions, this app is so crappy it errors out on sending error report to developers

Functions well and easy to use. The UI is bland but great for diagnosis and reset codes.

The application fails to diagnose errors and not work. I have purchased it without any benefit.

I will never buy a car again without this ;-)

This is evening better than pay torque. If you're technician you need this. This recommendation come from technician

App rocks, does more than my $150 dollar scanner. Paid 9 bucks for elm327 bluetooth plug on ebay and less than 5 for this app. Best 14 bucks you can spend on a scanner!!

Tried several times, could not connect to the ECM, was able connect using OBD II car doctor right away?

Not worked with suzuki alto Some time it connected but suddenly disconnected from vehicle and shows voltage only

I am on android 6.0. Is there a fix for this?

Works and would buy pro version But I have trust issues with my money.

This crap doesn't work...don't spend your money on this....

Clears codes

Errors cannot communicate with the ECU

Great program! Tried to order full, but error.

Would be nice to know what the pro version will cost me before i actually buy it!!

Clean my errors without any problems.. great!

It works but sometimes freeze data

Free version worked for me to reset engine light. Connected by WiFi easily once settings configured.

Like I said, no real useful info

30 seconds had my code. Thank you for saving my day

App is OK, nothing special. Is anyone knows some OBD app that shows transmission fluid temperature?!

Free app means rubbish app. Just waste of time.

Pro version crashes all the time.

Junk, don't waste your time

This works simple as that, if yours doesn't then check your hardware.

Works great reads all vehicle parameters. Great programing!

Works with both Bluetooth and wifi

Great for a quick look at trouble codes.

Would NOT connect. Junk!!

Brilliant app ...upgraded to pro version and woow this is the best app by far. I hope you will add ABS & air bag faults soon .welldone and thank you
