Rock solid for me

Been using this app for over 2 years with no glitches, freezes, or exporting problems on my iPhone 6. Not sure what all the 1-star reviews are about, maybe people who are using older devices or outdated versions or iOS? I can see how this app would tax an old iPhone 5 processor pretty heavily but on my 6 it continues to work well. Nice to have the higher bitrate and resolution when needed. They keep the app updated regularly and it continues to be refined with each new release.
