A little plug for my (100% free) Android app called ScoreTracker DC.
It's a simple app that lets you track scores or counts for different items -- for example if you wanted to keep track of the scores for each player in a board game.
It's built on the same codebase I have used for my other Android apps, which means it has multi-device synchronization options, tabs for grouping items, etc.
Each item has a quick +1 and -1 buttons but you can also click any score to get a nice calculator dialog to make bigger changes.
I've recently added a custom font scaling option which makes it particularly useful for displaying names and scores in very big clear lettering.
You can download it from the Google Play store here:
