My feedback...
1. Trial is way too short for a $99 purchase.
2. Adding a photo, deleting, and re-adding uses up "trial cards" - so the trial is really just tutorial-level playing with the software.
3. Not clear why I can add elements to the top layer... why would I have an Empty Board and a photo next to each other? Why can't I drag the photo into the Empty Board? Instead, the photo covers the board. Confusing.
4. I know you aren't alone, but why do you need my email address before I know anything about this app? Just let me tap open and experiment before you ask.
5. If you must have an email, why aren't you supporting Sign in with Apple so I can use a relay email?
6. I'm not clear when I would open this app. I would've prefer a full page of example boards to see how power users would/will use this tool. I can always delete example boards, but instead I have a blank page and 4 second videos. That screams time investment and learning curve ahead.
