Premium user here. Phenomenal app! Truly does what it says it does. One small critique for dev. There can be "writing to disk" issues when nearing the end of a recording session, and the device runs out of disk space. Was able to retrieve and recover some of the media file with a third-party app. This can be device or scenario specific. Great app.

My OS doesn't allow for a secret or hidden album, that's ok however, it would be nice to be able to choose the album that the pictures and videos go to other than the main photo album.... and after purchasing the VIP package I was still getting pop up ad's .. the"REMOVE AD'S"setting is turned on now but I was extremely irritated that they were not automatically disabled at the same time as the banner ad's. Seems like a desperate move for a few more views after charging $19.95 already DISGRACE !

Would've gave 5 stars (a couple/few months ago) but the app all of a sudden stopped saving the recordings to gallery/phone... Kind of a deal breaker. I will be searching for a new app... No, slow motion, no fastforward/rewind where you can see where you're at in the vid, ect. Makes the app trash as far as I'm concerned... Once I find an app that does the same but saves vids and pics to your phone/gallery, I will be uninstalling this app
