Fantastic app, works flawlessly with my 1998 Volvo S70 and has functions matching or even exceeding dealer tools

Amazing! 1997 Volvo 960. I had removed airbag, turned on car and srs light came on-there was no problem it was my error. Took a minute to get the Bluetooth to connect but it was written in the very small (font) instructions how to connect. Thank you people from Finland and others who have developed this app!

Great app that enables you to read every module (on a Volvo 850/V70) individually, which is something even Volvo Vida won't do. A must-have app for every Volvo 850/V70 classic enthousiast. Do make sure you have a good, fully functioning ELM-327, because many of the Chinese knockoffs I have tried don't have the full ISO-9141-1 control set available which makes them useless with this app. Would love to see IMMO programming in this app, by the way. Edit: OBDLink SX adapter works flawlessly.

After hours of searching for a way to use my bluetooth obdII device to find the total miles on my 1996 Volvo 850 I came across this and it worked!!! I just started it up, linked it with the device (already inserted into the port) and ran the scan function. Thank you!

This app is awesome! I installed it nearly 2 years ago and it has been indispensable for reset service lights, pulling mileage from the computer and reading live data. I dont know if it can reset the SRS light but would love for that to become a feature.
