Not just worthless, but crazymaking
Get this app if you want to be driven crazy. Looks cool - tries to simulate real drum heads when you tap them, even varying in sound from the edge to center, and some cymbals and other sound effects on the side. But it only lets you access one lesson. Afterwards, every lesson you try doesn’t work and instead plays an ad. And not just a short ad, but a 30 second ad that you cannot exit from. And not just any ad, but ads with middle or high school kids and loud, bouncy music. The interface is awful - I could not navigate and there was no explanation on how to. There also would be a “Watch on YouTube” banner that would float up and cover up buttons and keep popping you over to YouTube if you tried to work around it. So maybe, just maybe you already play the bongos, don’t need lessons, and just want an app where you can practice on some electronic drumheads this might work. But it would probably drive you nuts that the creators maybe have not seen real bongos and made them the same size on the screen.
