Update

I created some new features and removed few bugs.

new features:

• create counter by hour, for instance 9:00 will be calculated as time up to this hour, you can choose 12h or 24h time format in settings
• create counter with date and hour, just combine date and hour with underscore (date_time)
• create blocked counter, which means it can't be pauzed and starts immediately, just use keyword b or block
• each counter have got a finish time, so you can see when it gonna end if it runs or when it gonna end if you start it now (if it is pending or pauzed)
• I wrote about it in more details in project readme and in about modal on app page
