Download or reviews of FourStroke application.

FourStroke is a powerful tool that analyzes and displays real-time vehicle sensors and data through your vehicle's OBD-II port, a port standard on most vehicles across the world. Use of this app requires a compatible OBD-II Wifi Adapter. Our app is FREE to pull and clear engine codes along with most other functionality! FourStroke will work with any non-proprietary OBD Wireless adapter. FourStroke can convert your iPhone into a heads-up display of just about every sensor your car supports, without needing expensive gauges. Sensors include RPM, coolant temperature, vehicle speed, air flow, O2 sensor data, and more (sensor support varies based on vehicle). Quickly diagnose a check engine light (CEL) by pulling up exactly what error codes are present. FourStroke automatically turns the code into a readable description. Your vehicle also may store 'Freeze Frames' that detail what sensor data was present when the CEL first occurred; FourStroke can display this information for you. In app purchases are availble for reading more advanced sensors as well as a performance unlock for a dynanometer (horsepower & torque reader) and a 1/4 mile analyzer (which is only partially limited for free users). DISCLAIMER: This app requires a third party OBD2 adapter. Please visit our website for details. Like most others this app does NOT support ABS codes. Bluetooth adapters are not supported.

FourStroke Reviews

  • Excellent

    By Daddy-OO
    I’ve tried loads of apps to try and turn off my engine light, they all ask for payment when you click on the clear fault button. On recommendation I trie 4 Stroke, it connected quickly, found the faults cleared them and turned off my engine light, all within 3 minutes. Got to be the best app on here. Well done guys!

  • Great app but......

    By What nicknames are free
    Would be better if you could turn off an engine warning light with no dtc's stored. Very easy to use app and would recommend to others. Would give 5 stars when the above suggestion is updated.
  • Better than expected

    By VeeSixJC
    Used this with the typical eBay dongle on a merc SLK connected first time - very pleased
  • Absolutely amazing

    Can't believe this works so well when all the others work so poorly and they aren't trying to sell you an £80 upgrade just to read a BMW code this one read my 2005 BMW 1 series straight away and actually gave me a code I could use unlike another app that I used witch would not give the code I'll pay for the upgraded version to help support such a good app thanks.

    Very good app. Connects to my OBD II wireless device easily and for minimal expense, displays loads of real time sensor information. It includes a DTC freeze-frame feature which logs sensor info at exact time of DTC. Helped me sort out a problematic O2 sensor fault.
  • Disappointed

    By Suicide did
    Shame I had to pay 3.99 to get more than an rpm reading on my iPhone 6..very clonky readout and inaccurate readings. My old torque app with the Bluetooth elm 327 was far better...will be going back to that untill this improves..
  • Where has this been all my life!?

    By Drachyr
    This is fantastic. It is more informative than the garage, and I didn't have to spend hundreds of pounds for the information. Even if you're not very tech savvy it's still entertaining and highly interesting. Couldn't recommend more highly
  • Perfect

    By Supernatural monkey
    The app is spot on
  • Srs air bag reset function

    By Millan1978
    Brilliant app only missing srs air bag reset function which would make this a all round excellent app and top obd scanner
  • iOS iPhone 5s perfect

    By Newbs11
    Brilliant free app and synced in seconds with iPhone 5s. Didn't have to do anything except select the OBDii wifi signal. Bought from Amazon "I geek" ELM327 usual adapter, get the wifi version as Bluetooth won't work apparently! So, great app good features and for only £2.99 I may get the full unlocked version. Wouldn't mind seeing torque and horsepower etc just for the gimmick factor! Don't hesitate petrol head. Lol.

    works great on both of my cars. Diagnoses any faults and can't even use as you drive to check temps or revs or anything else you want and has a sensor fitted :) Highly recommend this !!!!!
  • Amazing - beats the competition

    By pc rob
    This app is great. I've used others but I found them buggy and I had issues with them crashing all the time. I had no such problems with this app - works every time and connects quickly to your interface. I used it for a couple of weeks when my engine light was coming on and I was loosing power - this app let me use my car to get to work (until I could get it into the garage). The only thing I would have liked was a button on the homepage to clear all faults - but that was particular to my situation. 5 stars!

    Works great reads & deletes fault codes on Merc A Class this is excellent for a free app, most other app will charge for in app purchases for this service.
  • Works great

    By Asmblah
    Tested on both an '06 Ford Ka and a '12 Vauxhall Corsa, works a treat.
  • Great compared with competition

    By Swim49
    Downloaded four different apps to read my new OBD adapter. This was the only one that worked as far as I could work out. Others either did nothing without payment (or maybe registration but had no intention to register for product that may not work). Has an easy to use gui, good looking and adaptable view showing graphic representation of desired stats. Yet to have a fault code so not tested the ability to clear but was really pleased with app, and may upgrade to pro if I need the other features. I am not a mechanic, but this is an honest home amateur review. So far does exactly what it reports to. Used with elm327 from eBay
  • Worked perfectly!!!

    By DavidandLiz
    I tried a couple of other apps with my vgate wireless module - but this one was the only one to work without issues. Very happy, job done....would recommend.
  • Great little app

    By Dugstar0
    Connected first time, found my fault and cleared it. Can't fault it.
  • Works great

    By THC-appleID
    Took a while to get the V-Gate adapter to talk to the car, but the diagnosis page showed where the problem was. Quick power cycle fixed. App works great, shows all info I need. Just wish I could have multiple dials on the dashboard display.
