A place for experimentation: short exercises that test one idea at a time. They stay here while we measure whether they help. What helps earns a place among the games; what doesn't stays on record, with the reason.
One piano note, two seconds to find the key. Miss it and it replays while the Diapasão says its name. Eight rounds.
Pick a color map for the notes, hear twelve with color and twelve without. Does color help you remember?
Hear each note and pick a picture for it. Then the note plays and you answer with the picture.
Tell the forum how you picture the exercise. It doesn't have to be perfect; it has to be testable.
Share it in the forum →A small exercise that tests one idea only: no levels, no saved score, no sign-up. The games in the app are the path that has already been tested, with levels, a ranking and saved progress. An experiment is the opposite: short, rough and provisional. Some experiments get settings (more rounds, a different time); to use them, all you need is a free account, and they stay saved in it.
Each page records, anonymously and in aggregate, how many people start, how many finish and what happens next. Only with that does an experiment change its label, and nothing is judged on less than two months of data. Nothing gets deleted: an archived experiment stays on the list, with the reason.
Without an account, nothing is saved to an account: the exercise works fully without logging in. With a free account, the settings you choose stay saved in it; the score still stays out of the ranking. The measurement is an anonymous, aggregated count, to find out whether the idea helps.
Because the app is the path we already know works, and every new thing there costs attention from people who are training. This is the place to fail cheaply.
The test measures where you stand, with no correction along the way. The experiments test ways of training. One is a ruler; the others are hypotheses.
