Some merits, some flaws
It would be good if this app could save videos to keep editing them. It can currently only work on one video at a time. There is no way to come back to a video, reedit and rexport. Another issue is the speech bubbles are not very editable. There is a lot of padding around the text and doesn't seem to be a way of making the text larger and the padding less. You can color text but not the bubble itself. Finally, I'd like to see more interesting styles of bubbles, such as iMessage, What's App or SMS style etc. The one feature that is nice about the bubbles is editing where they occur on the timeline. That part is well executed. It could be improved with some time code information. Right now you just ballpark where you think a text bubble should come in and fade out. You have to preview each time to see how it looks. Not bad, hope the developer keeps improving it..
