Always on the lookout for useful things to add to the sidebar links, I found, indirectly through Facebook, the Tenpin Toolkit app, developed by British coach Simon Kimber. It’s kind of a Swiss Army knife of bowling apps, as it has these features:
- Angles & Targeting
- Axis Tilt & Rotation
- Ball Speed & RPM (Rev Rate)
- Observation Trainer
- Pattern Library
- Score Calculator
- Spare Names
Each of these tools is described in more detail on the app’s homepage (now linked in the sidebar, under “Bowling Software/Apps”), along with links to the app on the Apple Store and Google Play. The app does cost about US $10, but it could be the best $10 a bowler spends on technology.
