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!

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

    I used it a long time ago when I had my Galaxy S4 and was routed. I have not had a rooted phone in over four years and was not able to use it. However, when I got the pixel 3 I was able to root it and, initially, it didn't work, however, it finally does and it feels awesome to be able to use this program again. Thanks a lot for such a wonderful equalizer program and I will continue to use it as long as you make it to an updated.

    Brilliant ; Used for years . I'm a self proclaimed audiophile & the key to tuning is to be subtle. This caters for my needs perfectly For those struggling to install ; head to settings & change mode from normal to compatible ,No need to download driver. Restart & within your chosen audio app (i use black player & Power Amp) head to settings or EQ / Audio FX & select stock EQ
