Efficient training through adaptive frequency.

Cases you struggle with will appear more often in practice.

Upload your own algorithm and memo files, or download auto-generated templates based on your letter schemes and buffers:

Files are optional. Templates are generated from your scheme/buffer setup.

Double-click the cube (or just start typing) to open.

.KEY      look up memo, alg, and stats for a case
+KEY      mark a case as difficult
-KEY      unmark / reset a case
m KEY=VAL save a memo word for a letter pair
a KEY=VAL save an algorithm for a case
e / i     export / import all data (opens Data)
h         open this help panel
d MODE    change mode <edge><corner>[parity]; o=off, c=adaptive, r=random
t CAT     show top 7 most marked cases (filter by category)
c NUM     copy latest NUM solves to clipboard (default: 1)
u         force refresh cached files

You can always return here with the h command.

• Open Settings: Double-click or tap the scramble text / press ` key
• Start Timer: Long-press the cube / press space
• Next Scramble: Press Tab / click "Next →"
