The only Polish alphabet app that makes you write every letter and scores your handwriting in real time. Not multiple choice. Not drag-and-drop. Actual writing. WHAT MAKES THIS DIFFERENT: ▸ Handwriting canvas scores every stroke — build real muscle memory ▸ All 32 letters — including the Polish specials ą ć ę ł ń ó ś ź ż ▸ Nail the sounds that trip everyone up — like ł, which sounds like English "w" ▸ Hear clear native pronunciation for every letter ▸ 3 quiz modes: letter→sound, sound→letter, audio→letter ▸ Listening drills — hear it, then write it from memory STAY CONSISTENT: ▸ Daily Challenge — 8 questions picked from your weakest letters ▸ Spaced repetition (SM-2) schedules each letter's review ▸ Streak counter & achievement badges keep you coming back ▸ Weekly charts show practice time & accuracy trends DESIGNED FOR REAL LEARNING: ▸ Step-by-step lessons from easy to hard ▸ Create custom letter groups for focused drills ▸ Dark mode for late-night sessions ▸ Available in 10 interface languages Planning a trip to Kraków, connecting with family, or starting Polish from zero — this is the fastest path to reading and pronouncing Polish correctly.

Don't watch BFS run. Be BFS. Stepwise is a daily training game for software engineers, built for a phone: tap, drag and swipe. There's no typing on a tiny keyboard. BE THE ALGORITHM Execute real algorithms by hand on freshly generated inputs. Tap nodes in the order breadth-first search visits them, pick which node Dijkstra settles next, sift a value through a heap, probe a sorted array like binary search. Every move is scored, and the puzzles never run out. THE DAILY SET Five challenges, the same for every developer that day. Keep your streak and share a spoiler-free result card. A RATING THAT MEANS SOMETHING Every topic has its own Elo, like chess puzzles. Difficulty adapts to you. MORE GAMES Big-O Blitz, Bug Hunt, Line Up, Output Oracle (Java, Python, SQL), Pick the Structure and Pattern Spotter. There is also an Engineering track: race conditions, SQL traps, index choice. Every answer is checked: generated puzzles take their answer key from the real algorithm, and code snippets are verified by actually running them. Challenge a friend with a link to the exact puzzle you just solved. Your full history is saved, so you can replay anything you missed.
