Every key you press is timed. Smart practice finds the keys and letter pairs that slow you down and serves words built around them.
Presspace times every keystroke you make, in every mode. Smart practice turns that record into a word list. Keys you miss count most, then keys that are slower than your own average, then awkward letter pairs: the rolls and stretches that interrupt your rhythm, like ce or my.
About four words in five are chosen for those weak spots. The rest are ordinary common words, so the text still flows. A strip above the words shows what it is working on, and it updates as you go.
Most of your typing time goes to letters you already know well. Improvement comes from the handful that you do not, and a general test only meets them occasionally. Concentrating practice on the weak spots is the same idea music teachers use when they have you repeat the tricky bar rather than the whole piece.
Still learning where the keys are? Start with letter by letter or the typing lessons.
It looks at how often you miss each key, how long each key takes compared with your own average, and which two-letter combinations are slow or error-prone. Words that contain a lot of those weak spots are served more often, with ordinary words mixed in to keep a natural rhythm.
Yes. It re-checks your timings every dozen words, including the ones from the run you are in, so the focus moves as soon as a key stops being a problem.
It needs some data first. A couple of runs anywhere on Presspace is usually enough for it to start aiming.
For improving, usually yes. A normal test spends most of its time on keys you already type well. Smart practice spends it where the gains are.
