Tally allows you to count anything with ease via iPhone or Apple Watch. In portrait orientation, a single tally counter takes up the majority of the screen. Buttons around the edge allow you to quickly count up and down by values of one, five, and 10. In landscape orientation, the screen splits and allows you to manage two separate tally counters at once. Tally also includes six-sided and 20-sided dice in case you need them.
You want a simple counter.
You need support for additional counters. This one supports two total.
