diversify timer function#4581

please take inspiration from the app ‘yeolpumta’ :)
i find it a hassle to have to switch between app. yeolpumta has a feature that actually records how long you’re in the focus mode and have the app blocking function (for tiimo: i suggest implement in mobile devices). they also have stopwatch funtion other than just a timer.
additionally, a flip clock page in the focus feature would do great. would be nice to reduce switching to other apps!!
