Sticky Note Pro: Post-it&Memo

I scrolled through my previously open apps on the iPhone and saw what I wanted from Sticky Note Pro then it disappeared. Where did my history go? I have critical information in those notes. My iPad is receiving the copy with no problem. The history is gone on there as well just a note I wrote on the iPhone as a test is there. Somewhere I read that I should open the Settings app in the upper right hand corner, but neither my iPad nor my iPhone has any kind of settings button. I looked in the OS settings app, and all I saw was a list of apps I could write to. Please let me know where I could find my history notes. Thanks.

Great colors, easy to size, keep on top and move around. I use it for alot of content creation and synchs well with my iPhone. Quick Q- Can I print from the note? I am not able to so far and also how do I export If i want to put this content elsewhere?

Developing a simple app, such as a basic note/sticky single-UI popup, should be a walk in the park for most any developer nowadays. After jotting down a simple "Today's To-Do list" as my first Sticker, I momentarily switched my focus to my browser; but as soon as I switched back (using Cmd-Tab), everything I had typed just vanished! I looked everywhere in its very very limited menu options to hopefully recover what I had typed, but no luck! This is beyond poor of an excuse - it's desctructive! Imagine some poor shmuck types a massive content, and it just simply wipes it away! And get this - it costed me $7.98! I know it's not a lot of money, but for a paid app, this is completely unacceptable! How the heck has it received a 4.6 star rating, I'll never know...
