Wont even open

When I first got this app, I was quite excited about it. After two hours, however, I have come to detest it. I opened it once it finished downloading, closed the popup asking me if I wanted to upgrade to the paid version, and made a little test recording. Upon finishing that, I tried to name the recording "test". However, the app quit quite inconveniently and unexpectedly when yet another popup appeared, asking me if I wanted to buy yet another app, presumably made by the same developers. I tried repeatedly to reopen the app, but to no avail. Now, I cant even remove the app because it thinks its still open, when it is clearly not. I dont know if anyone else has had this problem, but its still a bug and needs to be fixed.
