Bowling Ball Arsenal 7. Notes 8. Score Calculator 9. Spare Names --- 1. Angles & Targeting Plan & visualize a shot from the start of your approach to your target, helping you become more accurate and consistent.⁠ Add overlays, such as entry angle, focal point, distance markers, and save favorite shots. Video mode can apply all the above to previously recorded videos, or use camera more when practicing, with up to 30sec delay, for continuous action replay of every shot. --- 2. Axis Tilt & Rotation Take a photo or video of your bowling ball with a PAP (Positive Axis Point) marker and position it in the guide for your approximate axis tilt and rotation. Great for working on control & consistency.⁠ --- 3. Bowling Ball Speed & RPM In simple mode use the start/stop button to calculate bowling ball speed in real time. Advanced mode can load in a video for more accuracy, and rev-rate calculation.⁠ --- 4. Bowling Observation Trainer When we let go of the ball, many of us immediately look up to see the end result at the pins. We don't see the journey the bowling ball takes to, and through, the pins, so don’t see differences between pocket hits that do and don’t carry. ⁠ ⁠ Practice ANYWHERE with the Observation Trainer and learn to focus on four key points of every shot that give you the info you need to make better decisions and start striking more. --- 5. Pattern Library Instant access to details & diagrams of hundreds of bowling lane oil patterns, or enter your own custom patterns. Load any pattern into Angles & Targeting to plot your shot directly over it and plan how you'll attack the lanes. --- 6. Bowling Ball Arsenal Searchable library of over 1,500 bowling balls and a way to manage your own arsenal. Organise bowling balls into separate bags and keep track of information such as surface, layout, important dates and more. When looking for something new, use the Bowling Ball Library to find exactly what you want, with filters for brand, cover & core types, RG, Diff and more. --- 7. Notes Keep track of information about your bowling and equipment. Create general notes, or add notes from within most of the other tools, such as for oil patterns, your bowling balls, Speed & RPM readings, Observation Trainer scores and more. --- 8. Score Calculator Whether earning how scoring works, teaching youth bowlers how to score, or just giving your brain a rest at a Triple-X fun night, there's lots of reasons the Score Calculator can come in handy! --- 9. Spare Names Just for fun, tap the pins to see nicknames of common bowling spares you probably don’t want to be leaving! --- "Every bowler should have Tenpin Toolkit on every device they own. It’s an incredible information source and provides so many things to help you learn, get better and challenge yourself." Tim Mack USBC Hall of Famer & Storm Bowling Director of Global Relations --- "A brilliant app with tools to help you develop and learn different skills.

The video delay function stopped working.( Data transfer doesn't work, QR code doesn't appear. Please fix it. ### 5/5 — Mr 803 *2026-03-14, version 2.7.3* I love the software the content and help when drilling a ball ### 4/5 — New to the game *2026-03-07* Great app, I was amazed at how accurate he actually it is providing that you put the right information in in the beginning, but it is helping me improve my game. ### 5/5 — Great app! *2026-02-28* This app has definitely helped my bowing game since I started using it last month. There’s so much useful content, especially for bowlers like me who are only recently getting serious about their game. I especially like the section about bowling layouts, which will help me understand how I can change my arsenal. The only feature I would like to see is some sort of cloud storage so I can view my information on multiple devices. There is a data transfer utility with the app but I think cloud storage would be simpler. Thank you for making an excellent bowling app! ### 5/5 — Great App *2026-02-21* I have had the premium version for about 3 years now, mainly use it to compare my different balls Diff and RG, very nice app, I wish it had some sort of addition in the app where I could input my scores and it would keep track of my averages, my misses, and my spare percentage. Other than that it is a very good app for someone who wants to take their bowing to the next level. ### 2/5 — Unstable *2026-02-14, version 2.7.3* App is not stable enough to even begin to use. While it doesn't crash outright, any screen used reloads constantly. ### 1/5 — I would like either a bug fix or a refund. *2025-12-25* I can’t use Observation Trainer on iOS 26.3. I want my money back. ### 5/5 — Great toolkit for bowlers *2025-12-21* I was looking at bowling apps and this one came up. The subscription is worth the cost of the detail you can get out of this app. In one day I have learnt more about my balls and determining if I have made good selections. The aiming module is awesome and cannot wait to test it out in the lanes to help improve my shot making. This app is great for all amateur bowlers wanting to learn about their kit, layouts and more. It’s got me hooked. ### 5/5 — Worth The money *2025-11-19, version 2.7.2* Great for seeing different layouts on bowling balls with your pap ## Frequently asked questions about Tenpin Toolkit ### What does Tenpin Toolkit do?
