I really enjoy using this app and LOVE that it graphs my productivity (i.e. # of pomodoros on its own). I enjoy the colors, though I too wish there were more shades and colors available (some days I want purple!). To comment on the previous reviewers request that the timer be an option for landscape orientation... I have found using the portrait lock button, available from the swipe up control center, very helpful.
Otherwise this app is fantastic! I might also suggest an option to record the number of times you get distracted during your pomodoros. But that isnt that important to me. This app is really everything I was looking for in a pomodoro timer app: option to change pomodoro/break lengths and a graph. I also enjoy the option to change the background color.
