This app is exactly what I was looking for and I love the logo and the simplicity.
I would, however, like to suggest one change; I wish the text that you can add on the front card (the title) was in paragraph form and not subject line form. While I haven’t reached the text limit, it would be easier to edit text if it were in a box and not a single line.
And maybe have the backside text optional. I don’t need it for what I’m using this for, but you don’t have to flip the cards unless you want to, and you can just add a space to the back text line so it allows you to add the card to your deck.
