This application allows you to play videos saved on an SD card in the "Aikido Techniques List" directory.
If this directory does not exist, you must create it with the phone's file manager.
All the videos in this directory are displayed in a list.
A filtering field makes it possible to reduce the list to the only selected criteria (attack, technique, form, etc.)
A category manager allows you to store your favorite filterings.
ATTENTION: this application does not contain videos. It's up to you to copy them to the target directory.

Tips:
Name each video as follows:
technique - form - attack.mp4

For example: SWW - ikkyo - Omote Ura - Shomen.mp4

In the search box you just have to type "shomen ura" and you get the list of all the videos containing "shomen" and in the form "ura".
The filter criteria can be entered in any order.
