So, did the OP find his own product useful?
I work on contract iOS jobs and I need to track my time to invoice my clients. It sucks using my web browser to start and stop the timer. I also wanted quick access to all my tasks, past and present without going through a slower web UI.
Also the app comes in handy when I need to jot down a quick note or remember something.
Maybe I should incorporate some of that ^ on the site.
There does seem to be a saturation of apps on my platform: windows phone to where just another makes no sense. Mostly devs make it for themselves and since we're all unique, these things are like snowflakes too.
