"KiZuKi" is a golf swing/video checking app.

KiZuKi allows you to easily import swing practice videos taken with your smartphone camera.

And, thanks to optimization, you can easily and smoothly operate slow playback, frame-by-frame forwarding, rewinding, etc. using knob functions.

You can also sort by club or shooting date, which is useful for reviewing your progress or when things go bad.

Furthermore, with KiZuKiI, you can leave notes for each video.
You can record what you notice in each video, such as the parts you want to correct or your own quirks, which is very useful for improving your swing.

By leaving detailed notes on the video, you can see the total trajectory of your practice (swing improvement) over time, which is great for maintaining motivation.
