It's handy if you bowl in different centers, or love stats. I have the pockpc version and use it primarily to keep track of my spare percentages. It's nice that when I go to a house I've already bowled in, it can tell me how to play the lanes, but it's only for stats at my home house. I'd recommend it strongly for someone in a traveling league, or bowls a lot of tourny's, but if you only bowl in one house on a given pattern, it's o.k.
