Avi to mp4 converter

I use to convert my video on my iPad with the super cool app iConv (Evan Hurst) !
But the app completely disappeared from app-store... ?

It’s strange cause I got the app on my old iPad with iOS 12.1 and it work perfectly !
But I got the new iPad Pro 11 and start it with a restore of my old iPad and it did not recover iConv... ?

I call Apple and they have no info why it disappeared and can not give it back to me...

I e-mail Evan Hurst but no news for now...

So anyone have a good iOS app to replace iConv to convert avi to mp4 on iPad ?

How about use some desktop converter, like Joyoshare Video Converter, HandBrake, and more? Also, you can search online video converter on your iPad's browser. You will get many results. As I know some of them support convert video on phone, but the conversion speed is not good if your AVI files are too large.
