Music Notes
Read the staff without thinking about it. Name the note, again and again, until reading the page stops being the slow part.

What it does
Just name the note
One note appears on the staff and you pick its name. That is the whole loop. Nothing to learn before you start, so the first second is already practice.
Treble and bass
Both clefs are covered, so the gap where one of them reads fine and the other doesn't gets closed. Ledger lines are included.
Speed is recorded
Time per note is kept alongside accuracy. Sight-reading is a question of speed rather than correctness, so that is the number worth watching.
Reading is a matter of repetition
When people say they can't read music, usually they can. They are just slow. The answer is reachable by counting, but the piece has moved on by the time they get there.
Counting
Working up from a landmark line, space by space. You arrive at the right answer, and it costs a few seconds per note.
Recognising
The common notes start arriving without being counted, and the speed of reading a page changes visibly.
Not thinking
The name is simply there when you see the note. At this point reading stops interfering with playing.
Getting between those stages takes repetitions rather than explanation, which is why a session is built to be over in a couple of minutes.
Who it's for
You can play, but reading a new piece is slow
Bass clef falls apart when treble is fine
Ledger lines still get counted every time
You practise alone and want something concrete to drill
Try one minute of it
Whether it suits you is faster to find out by playing one round than by reading about it. The browser version needs no install.
