App needs improving

Having paid $8 for the full version of the app I would expect that I be able to arrange my videos with no problem, however after I place my videos in order the app rearranges them to whatever order, ruining my yearly video. Extremely disappointing when you pay for the full version and it causes more problems! I’ve spent a lot of time trying to fix the problems and after doing so the app decides to rearrange the order of my videos again. Fix this or I will not be using anymore and will be advising others not to as well

i love this app but i think adding a focus feature to the camera would be super helpful. the camera is hard to use at the moment and i end up just filming on the regular Iphone camera.
being able to upload videos from any day would also be helpful because when i try to upload videos from snapchat, they don’t show up for the date i actually filmed them.

Developer Response ,

Thanks for pointing that out! The next update will have a focus feature for the camera recording in the app!

You can import videos to any day you want (Pro feature) if you tap the little import button on a day.

If you have any other ideas on how to improve the app please feel free to email me a

Almost there

I really want to like this. Calendar is cool. I want longer than 1s though and the plus button just doesn’t seem to do anything. Even when I use the try option. Would be happy to pay if it worked.
