Needs work
I get it’s the plus and minus feature, but if this is suppose to be simple, should t you be able to type in the numbers rather then having to repeatedly hit the plus or minus icon just to get to the tallied number mark? It time consuming and tiring if you had to use the number 100 as the tally mark especially repeated or higher numbers. This app unfortunately isn’t for me. When I’m usually in a hurry to get back to whatever it is I’m busy with. Other then that great concept.
