New: the Beginner journey. Eight chapters to work through at your own pace, now open to everyone. Home leads with it, and a quick tour shows you around. Free accounts get one journey chapter, one Practice Path level and two animated problems every day. New leaderboards: a weekly board under your Daily Mix and an all-time board, with medals. Choose the name others see. Exercises earn XP on your first try, and the Daily Mix pays XP every day. New for Pro: narrated video explainers. Watch a walkthrough right in the problem canvas, or a full lesson inside a cheatsheet. Practice Path levels now show how far along you are and let you review your answers at the end. Sign-up now catches email addresses that can’t receive mail, and the Problems filters use native menus. Signing in no longer crashes when the connection drops, videos keep their sound with the silent switch on, and “Saved for later” opens your saved list directly. New physics animations for Super Egg Drop, Water and Jug Problem and Car Fleet, plus a new problem: Gravity Sort. The Learn screen is rebuilt. The problem and the approach are full-width pages you can just scroll, with no header in the way, and the animation has the canvas to itself. Playback now sits on the code panel's handle, and the panel rests at any height you drag it to. Exercise sessions gain a Previous button, an exit that keeps your place, and complexity answers marked right or wrong. Final frames highlight the answer instead of the whole array, and your zoom survives a growing tree.

Practice has a new path. Work through districts of exercises level by level, and watch your route light up as you clear each tile. Cheatsheets are rebuilt: a grouped overview first, then one section at a time. Plan your interview on a real calendar with a start date, not just a countdown. Every code puzzle now comes in Java and C++ as well as Python and Kotlin. Practice sessions now stick to the number of questions you pick, plus a fix for tab switching.

Bit now levels up with your streak. Ten stages, each lighting up a little more — tap him on Profile to see the whole ladder. N-Queens gets a real chessboard: queen stamps on the tree, pruned branches in red, and a gallery of every solution found. DP tables shaded by value, and hero cards that keep the best and current numbers in view while a walkthrough runs. Insight cards follow the cursor, trees move as nodes swap and grow, and linked-list links route cleanly under the row. New quizzes and code puzzles on six visualized problems. Step through from the sheet handle, jump back into practice from the interview countdown, and keep your progress even if you leave a screen right away. Plus bug fixes and polish.

Google sign-in on iPhone and iPad now finishes inside the app — no more Safari detour. Meet Bit, your new companion, now living across the app. Set your interview date and watch the countdown on Home. Your onboarding answers now follow you to every device. New animated walkthroughs, and smoother, clearer motion in every visualization. Twenty problems are free to explore, animations included. The keyboard now dismisses when you tap outside a field. Plus bug fixes and polish.
