GOLF LOCKER vs ShaftCPM Lite

Can you really remember all the tiny specs of golf clubs, shafts, and grips one by one? Have you ever found yourself forgetting how the club felt when you tried it out? GOLF LOCKER is an app that fully supports golfers with their gear management. ■ My Bag From drivers to putters, each club you currently use is managed digitally one by one. You can record not only the brand and model, but also details such as the shaft and grip, loft angle, lie angle, weight, and frequency of vibration. It also accommodates the use of multiple bags, such as for rounds and practice. ■ Test Play Log For clubs that caught your eye at demo days or shops, log them on the spot. You can save everything at once, including distance, trajectory, spin rate, evaluation, and even a photo of the capture screen. The one you like goes to your bag with just one tap. For iron, it is also possible to add multiple weights together. ■ Gear Ranking This isn’t a sales ranking or a review rating; it’s a ranking of clubs, shafts, and grips that GOLF LOCKER users actually put in their bags and use. You can discover the gear that is truly still being chosen, something you can’t understand just from catalog specs. ■ AI Chat Based on the contents of the bag you registered, the AI will assist you in choosing gear. We will provide personalized answers to questions like, 'What shaft suits this club?' and 'What is the balance of the setup?' based on an understanding of your setup. ■ AI Score Assessment Distance consistency, shaft weight balance, trajectory consistency, loft design, number of clubs—using standards close to a pro’s perspective, AI scores your current setup. It reveals improvement points that are hard to notice on your own. For those who love golf equipment, want to review their setup to improve their scores, or are looking for their next club. GOLF LOCKER is your partner in supporting your golf gear life. Download it now and create your own locker. *Some features are available only on premium plans

ShaftCPM Lite is the free version of a spectrum analyzer that measures a golf shaft's natural frequency in CPM (cycles per minute) in real time. You don't attach your phone to the club. Clamp the club to the edge of a desk, lay your iPhone flat on the desk, pluck the shaft, and tap Start. The frequency appears as a large number and a graph. Because nothing is attached to the club, its mass doesn't lower the frequency, giving good absolute accuracy. ■ About the free version ・Up to 3 measurements per day, about 10 seconds each. ・For unlimited measurements with no time limit, please use the paid version, "ShaftCPM." ■ Features ・Real-time CPM: analyzes the shaft's vibration and shows the natural frequency in large type. ・Spectrum & peak detection: plots the vibration spectrum and automatically detects the peak (natural frequency), with an approximate ± range. ・Desk-placement method: nothing is attached to the club, so its mass doesn't lower the reading. ・Portrait & landscape layouts; Japanese / English. ■ Please note Readings are approximate. Please use them as a reference, not as exact frequency measurements. They are more than adequate for comparing how stiff or soft your shafts are. This app uses only the accelerometer—no microphone, camera, or location. It collects and transmits no personal information or data.
