Many users are enhancing their smartphone audio experience with the popular ViPER4Android software, but some of us have a hard time installing the driver or they don't like the look of the app. As a solution for these troubles we have rewritten the app source and added all features to it. Many more features have been implemented too.
With our huge success of ViPER4Android 2.6 we decided to completely rewrite the ViPER4Android app in Kotlin. This allowed us to squeeze out the remaining bugs and clean up the code even more. After a long time of waiting for you and developing for us, ViPER4Android 2.7 is finally here!
There are many new features and improvements compared to 2.6, of which some can be found in the changelog. Hit the download button to check it out yourself!

    Sound awesome on my Phone (bq Aquaris x with lineageos ), but i have a warning from the Google playstore saying it is a malware, probably a false positive since i got it from xda-dev

    Никак не включается на OnePlus 6 (Open Beta 12), драйвер установил, но обработка не идёт. Очень не хватает возможности сохранять и загружать профили.
