Comments on ScanMaster for ELM327 OBD-2 for Android
★★★★★Richard S· Jul 31, 2025
This app actually clears up ghost codes thanks
★★★★★kingpest 13· Jul 20, 2026
This app teleported my truck to the mechanic who fixed it for free!
★★★★☆Michael Paisis (PofC)· May 9, 2025
It connects easily, and it gives u many parameters to look at. But you need a PhD in engineering to understand it most of it. Simple ones are fine but if each included a simple explanation it will make this app the best in the market; Also another thing is that I can't email the log files or download them in txt or notepad++ files, so we can easily read them.

App doesn't work. Constant error when attempting connection or to find adapter
★★☆☆☆Adam B· Jun 2, 2026
Nothings for free. You can't use it unless you pay. Some other apps let you use a lot of the functions for free
★★☆☆☆Chris Gane· Oct 4, 2024
I paid for this, and now it's gone back to lite. Not happy. Sort it out. After writing this review, and yes it's the only way to contact soft, the issue is fixed. Waiting for it to happen again. And it did. Wow.

How does one test the Lite or Free version to make sure all the functionality in the paid version is what you want. Huh ?
