Bowling Score Averages has been approved by Apple for release in the App Store. Bowling Score Averages is designed for high school bowlers, but other beginning or intermediate bowlers may find this useful too.
Simply input your total game scores and Bowling Score Averages calculates your averages. There is no need to input every frame score which are irrelevant long term anyway.
Current year and past year averages will hopefully show that with practice, you are improving!
As a bonus feature, you can input event notes such as goals to focus on, achievements, new equipment, or anything else that you wish to remember.
