Timers are great, I've been using them for more and more things lately. I still want to make a proper server-backed app one day that syncs any timers between devices though. I often enable them in my phone but then put it away when working on something on my PC and the widget in the app would be a good idea. Maybe even a plugin for my editor!
I buy packs of old school stop watches from amazon. They are practically disposable.
There is something really nice about having the timer disconnected from all other usability as a separate device and at the same time not having to care if it is lost or damaged.
May I ask how it you use it? I skimmed their site and it looks like they provide time tracking software for when you are actually doing something, but what I'm looking for is more a page with many "kitchen timers" ticking down all the time and doing a programmable action when they reach zero.
