Since iOS update 9 this app has never been able to scan older OBD2 SAE vehicles and has a hard time communicating with CAN equipped vehicles. Too buggy and I guess it was good while it lasted. ### 1/5 — Doesn't work *2015-01-14* Doesn't work with my wifi obd won't connect at all and no way to contact support. Waste of money??? ### 1/5 — Doesn't work *2014-11-29, version 1.62* Wasted my money. Don't waste yours. ### 1/5 — Won't connect *2014-09-10* Don't buy. Waste of money. Just freezes ### 1/5 — Complete Rubbish - Does not work *2014-07-24* I have an ELM327 that works with several pay apps, however not with this one. A connection is established but no data is transferred. Avoid This Wish I could get my 4.99 back - thanks apple for turning your store into a landfill ### 2/5 — wont work *2014-05-15* this app wont connect to my elm327 other apps work fine with it so why dosent this one its a shame as I like the look of the app and would like to use ### 2/5 — Doesn't really work *2014-04-27, version 1.61* It's a waste of money, other apps work without a fault on the same car with the same ELM327 adapter, this one only reads speed, RPM, temp and some other temp sensor I never need. Also on the available gauges that work update rates are low. ### 1/5 — Waste of money *2014-03-30, version 1.61* waste of money dont even connect to the app at all i want my money back. worst app ever ### 1/5 — OBD Unresponsive *2014-03-04, version 1.61* Will not communicate with my car using an ELM 327. I downloaded DashCommander and everything works great. This app is a waste of money. How do you apply for a refund? ### 1/5 — Doesn't work *2014-02-26, version 1.61* I've had this app installed for awhile with hopes that it would work when I could get the elm327 wifi unit, but that is working properly (tested by downloading a different app) and this app doesn't even recognize the dongle. I would like a refund for this app as I'm the first to post a review for a $4.99 app that DOES NOT WORK. ### 1/5 — Junk *2014-02-22, version 1.6* Not all functions work properly. I updated it, then it stopped working all together. ### 1/5 — Hmmm *2014-02-20* If this app worked it would be fantastic, good cheap alternative to rev and dash command. Sadly it crashes at random, doesn't display as much data and well....crashes any time you try to do anything! When it gets fixed this will be great. Otherwise stick to the others! (Which are way too expensive), I'm sure the devs will sort this eventually. ### 1/5 — Crapware *2014-01-07, version 1.5* Does not work, how can Apple let crap like this on? ## Most critical reviews (10 lowest-rated) ### 1/5 — Not working *2018-08-18* Waste of my money. Corn artists ### 1/5 — Avg fuel gauge confusing. *2017-06-13* Bought this app as it indicated a mpg reading. The reading on the app is confusing and doesn't offer any true readings. Indicated that I was avg 9mpg!!! Don't buy. ### 1/5 — Complete worthless *2017-06-11, version 2.2* A complete waste of money. I would not recomend this even if it was free. ### 1/5 — Useless App *2017-02-28* Why there's a charge for this app, I don't know. It's done nothing for me. Waste of money. ### 1/5 — Waste o Money 2 (too) *2016-12-21, version 2.2* I beg forgiveness from the previous reviewer... I failed to heed your words... and I paid the price - the price of this app, to be exact! Same thing, it connects and reads the tachometer and that's about it. Says the trouble codes not in database/ couldn't read codes. This car is a newish Subaru afore crying out loud!! It's probably the primary reason anyone gets an app like this. Don't fall prey to this app because it's cheap - it's cheap for a reason. DO NOT BUY THIS!! ### 1/5 — Waste of money! *2016-11-22, version 2.2* I want my money back! App reads out some things but does NOT out the DTC's which I the entire reason I bought it! Complete rip off ### 1/5 — Obd 2 *2016-02-20, version 1.81* Will not connect to iPhone 6 Plus, don't waste your money! ### 1/5 — Doesn't Connect To Adaptor *2015-07-07* Total Waste of Money wouldn't Recommend this App to Anyone doesn't work at all despite even trying to adapt different settings ### 1/5 — Doesnt work *2015-03-11, version 1.81* Sorry. This app doesnt work on my iphone six plus. Scans for wifi network but the phone doesnt find the device. The interface looks good. Seems like a decent app if it worked for ios. Hope that helps. ### 1/5 — Doesn't work *2015-01-21* Doesn't work with my wifi dongle, only shows the voltage, Don't waste your money. ## Most praised reviews (10 highest-rated) ### 5/5 — Scanner works well *2019-06-15, version 2.2* I use several scanners with my ELM-327. This one generates a very detailed report showing the primary functionality of my 1999 Jaguar XK8 engine. Worth the money. ### 5/5 — All fine on iphone6s *2015-11-30, version 1.81* Device: obd2 wifi (china) + iphone 6s Car: subaru forester 2009 It's works. See and delete engine errors. Sensors refresh is slow. ### 5/5 — Awesomee app but make an option *2014-11-06, version 1.62* For MPH. PLEASE!! Make a metric and standard switchable option. Especially for coolant temp and speedometer! This app is just about perfect besides that! ### 5/5 — not bad *2013-09-09, version 1.3* Tried on 4 different eml (wifi) devices. Did't connect on one of them. All features works but in some cars doesn't show fuel level (seems to be obd sensors problem). ### 5/5 — works fine *2013-09-08, version 1.3* Every thing works properly. Device eml327 wifi. Car Mazda 3. ### 5/5 — Works great *2013-08-17, version 1.3* Worked as soon as I plugged it in. Gave me all of the sensor values I needed and more. ### 4/5 — Works well but... *2015-03-06* This scanner works very well with the Wi-Fi connection. Earlier versions worked just fine however a recent upgrade stopped my portrait orientation from changing. I liked the fact that I could turn my phone sideways and get just the tachometer and speedometer window however after a recentit no longer inverts. Otherwise it's a good program. I wish they would update the program to allow for a sideways orientation. ### 4/5 — Good app *2014-03-08, version 1.61* I have been testing many OBD2 app I prefer these app most time easy too read on I pad and I phone very informative and the report page is great for future comparison and a record of how the PCM and various sensor monitoring. ### 3/5 — BUG REPORT *2019-12-15* I had posted to say that the app won’t work but in reality my kiwi scan tool has connection problems. Totally my bad. ### 3/5 — Worked 50% *2015-02-01, version 1.8* Worked nicely on a 2010 Nissan Frontier. Said 'no device detected' on a 2014 Chevrolet Cruze. This was using a wifi dongle from eBay. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
