Great app but it could have more options.
I love the app it does shoot at 4k but its best if you have a newer device I did experience an app crash once throughout using it but most of the time it runs well without any issues. I wish it had more editing options like for an example the one video I recorded ended up in portrait instead of landscape and theres no option to change that so far.
