Gaio (Google All in One).
This app puts my favorite Google services in one screen - Gmail, Tasks, Calendar and Google Keep (new alternative to Sticky notes and Evernote).
I made it because I was tired of keeping these services in a separate tabs of my browser or opening and closing them multiple times a day. Now, I just have to drag my mouse in top left corner of my screen, click and I see them all immediately, click again and I am back to desktop.
PS. I am php web developer and this is my first desktop app ever, so don't be too strict while judging it.
