Add and subtract hours and minutes easily.
Very handy App for, e.g. pilots, to fill out their logbook. No more hassle of making mistakes when adding up the block hours.
You can insert a time, hit the plus button and a make a new entry, which is automatically added in the total time field. If you want to delete a time, just hit the minus sign. It can't get any easier.
Anyone who needs to make time calculations should use CalcTime to do the job.
