My Merger(Free) App Reviews

I cant figure out how to work the app! I put my videos in and i cant figure out how to merge them. The i click the merge button it does absolutely nothing! fix it plz

this is demo - there is a logo overlay on the merged video. there are no words about it in description : ( it’s ok that you need to buy an app to get a clear video, but it’s not ok that developer doesn’t say that in description

Whats the point to be free if the app puts a big stamp onto your video? Unusable.

Tried multiple times to merge 5 short videos from photos on iMac. It “quit unexpectedly” each time. Garbage.

No error messages, just never did anything. Finally killed the application and removed it.
