We see your need. Please give us some time as first of all we are aimed to spruce up web app (make it perfect) and only after that switch to mobile applications.
The last also is not easy. There are too many bad trackers and we want to be different.

Just to make this idea sound even more awesome: Android app with Wear support.
Having the ability to start/stop timers from your watch would be pretty quick and handy. Probably allows for extension to more use cases away from the computer with ease.
