Curling Strategy Master can be used by coaches or players to illustrate what could have been done better in particular situations. These are then saved locally and can be replayed at any point. Drag a stone onto the trash can to delete it, or drag it into position... Once ready to complete a turn click next stone.
You can even group situations so that they can be easily searched. For example, you could enter the grouping as a specific competition or game. You may also choose to save an end at any point, but keep in mind you will not be able to come back to edit stone placements.
Special thanks to Alex Auda Samora for use of their karate icons which can be found:

The icon I have used was modified for use in the Curling Strategy Board app.
Additional thanks to icons8 for their hammer icon:
