Video Squishy is a video compression app for iOS (and iPadOS). I developed it so I could batch compress videos taken on my iPhone and then upload them to the cloud faster (and without using as much data bandwidth). I used it a lot to send family videos to my parents living in the UK.
Video Squishy has been available on the App Store for years now and has gone through several major updates. I started selling it at $1.99, later reducing it to 99c. Now it's free.
