Do custom exercises count toward Strength Score?

Not yet. Your Strength Score compares what you lift against a standard for that exercise. There is no standard for an exercise you made yourself, so it is left out of the score.

The exercises already in Kovo all have one. Your score keeps moving as you train those, and a custom exercise in the same workout does not lower it.

Everything else still works. A custom exercise earns XP for the muscle you picked, and every set you log on it stays in your history.
