Little app to allow quick marking of a time without looking at your phone. Reach into your pocket, press and hold on the screen, and it will mark the current time, with audio and vibration feedback, and allow you to record a 5-second voice description of what the mark is for. You can play back the audio snippets (with the "i" icon), and delete the marks by swiping.
