Your training set, your algorithms, stars and notes live in this browser on this device. No account, no sync, no smart cube, no ads. Export JSON to keep a copy.
An F2L case library in your browser: the 41 standard cases and your own, a training set of just the cases you pick, 3D playback one move at a time with turn arrows, a highlight that keeps only the pair in colour, your own algorithms that may stop mid-pair, stars and notes. No smart cube, no account. Free, local, JSON backup.
F2Lpad is a case library with a 3D player, not a coach. It shows the algorithms you keep on a cube; it never reads a cube (no Bluetooth, no camera), it does not time you and it does not grade your moves. An algorithm that ends with the pair unsolved is shown as exactly that, nothing more.
F2Lpad plays the 41 standard F2L cases on a 3D cube one move at a time, with an arrow on the turning layer. Set the highlight to Pair only and just the two pair pieces keep their colour. Tick cases into a training set, add your own algorithms and cases, and keep stars and notes.
Made for cubers learning F2L algorithms. No smart cube, no account; it runs in your browser and your data stays on this device, never sent to a server. Export JSON to keep a copy.
Example: put your problem cases in the set, hide the algorithms, and recall each random case before revealing it.
