Tenpin Toolkit: Bowling Tools

"A brilliant app with tools to help you develop and learn different skills. The observation trainer is a great way to train your eyes to start watching your ball go down the lane"

Verity Crawley
PWBA Professional & SCAD Team Coach


"I use Tenpin Toolkit at PBA level and as a coach. The lane play portion is fantastic, with the ability to show getting the ball right quickly which is crucial on the PBA Tour. The observation trainer is really good for helping players watch the ball go off the deck and determining dominant eye to help alignment. One of the best $9.99 I have ever spent and the most realistic app in the world for what I am doing."

Jim Callahan
PBA Tour Manager at Storm Bowling


"Tenpin Toolkit is easily the best tool I've found to help bowlers of all levels improve their lane play & observation skills."

Andy Penny
Team England Head Coach


"By far the best tool I’ve used. Perfect for helping players visualize the ball path and how changes affect it. I’m constantly using Tenpin Toolkit during competition and practice sessions. A must for any serious coach or player on any level."

Ulf Hämnäs
Norwegian Bowling Federation Head Coach
