I've been using an old HF $15 wired OBDII tester for a decade or more, but when I scanned a friend's car for her today, her neighbor came over to see what the commotion was, and then he came back to give me a Christmas gift.
It's a blue plastic OBD adapter with "ELM 327 mini Interace" on the sticker. He said he kept one in each vehicle, so he just pulled it out of his bimmer.
All it says otherwise is "Supports all OBDII protocols" but it doesn't have any brand or model identifier. He said it works (as he said some don't work).
He said I could get software for it on the net, so I ran an AppFinder search for free ad free Android apps rated over 4.0 with no in-app purchases, etc.
There were 18 results for free, adfree & inapppurchasefree, but when I raised the sort slider to exclude those with less than a 4.0 rating, only 2 showed up. *ULTRA OBD OBD2 CAR SCANNER ELM* by XAS Applications free,adfree,gsf?,rated 4.4 stars in 320 reviews with 10K+ Downloads
When I lowered the filtering criteria below 4.0, one more showed up.
*Smart Control OBD2 Scanner ELM* by SmartApps4Me free,adfree,gsf?,rated 3.9 stars in 2.94K reviews with 100K+ DownloadsFurther lowering the filtering below 3.7 brought up another app. *ELM OBD Terminal* by CHINH LUONG QUOC free,adfree,gsf?,inappfree,rated 3.6 stars in 25 reviews with 5K+ Downloads
Lowering filters to 3.5 brings up yet another set of free OBDII ELM apps. *alOBD Scanner* by Alexandre Beloussov free,adfree,gsf?,inappfree,rated 3.5 stars in 130 reviews with 50K+ Downloads
Which seems to have a command-line terminal CLI utility. *alOBD Terminal* by Alexandre Beloussov free,adfree,gsf?,inappfree,rated 3.1 stars in 72 reviews with 10K+ Downloads
Lowering filters to 3.4 brings up more free OBDII ELM apps. *CCY OBD MOBILE - for ELM327 an* by CCY - DIAGNOSTIC INTERFACES free,adfree,gsf?,inappfree,rated no stars with 5K+ Downloads
And then there are the apps which have too few reviews to be rated. *X-ELM* by v-checker free,adfree,gsf?,inappfree,rated no stars with 100+ Downloads
Given all that above... (all of which I've now installed on my Galaxy)...
Do any of you out there use these inexpensive bluetooth scanners on your car? Do you have recommendations as to what software and which features you prefer?
Is the use as simple as just setting up bluetooth on my phone and plugging this OBDII into the car's OBD port under the driver's cockpit dash board.
Do you leave them in all the time (the guy who gave it to me says he does).
I'll test it out tomorrow - but I figured I'd ask now that I've run the search for the free OBDII software that has no ads or in-app purchases.
