Occasionally, I need to count series of items. I've played with iOS apps for this purpose in the past but they were all such a carnival of ugly that I couldn't take it. Instead I reverted to notecards, tick marks, and pencils. I just downloaded Counters and I like it.

One thing I would change with this app is the requirement to open a specific counter before adding to its count. I'd like to see a setting or mechanism that lets me add to the counters from the master list.

This is a small niche, but one I'm glad to fill with my iPhone.
