Do you write your ideas in evernote, email, trello, apple notes etc?
I used primarily an email for such simple activity - writing your ideas down. But my inbox was quickly filled with all those ideas. I also needed to mark some as brilliant that I executed, and mark others as never to think such again. But I got this great mess of ideas in my mailbox, like never before. So I programmed a mobile app for myself, that just lets me write an idea down for later - and I can peacefully go through them later and decide if I am going to act upon them. What do you think? Would you be interested, if I published the app to public? Or would it be possible for me to find people interested in that?
