## What is Abacus Practice?

Build an answer with beads. Check it, then try your mistakes again.
Abacus Practice brings Japanese soroban and mental arithmetic practice to iPhone and iPad. Use the on-screen abacus, work with your own physical soroban, or answer mentally.

LEARN AND PRACTICE
• 16 introductory lessons with bead movement demonstrations
• Addition, subtraction, multiplication and division
• Flash mental arithmetic with adjustable speed and column-style drills
• Answer checking, per-question results and mistake-only review
• Start another session with your previous practice settings

CREATE YOUR OWN DRILLS
Generate problems from selected conditions and practice them in the app. Timed mock exams show answer progress and scores by subject. These are practice formats based on Japanese soroban exams, not official examinations or a guarantee of passing.

FIND YOUR FAVORITE BEADS
The standard wooden beads have a detailed natural texture. Pro adds skins including springy mint Jelly and transparent Glass, each with a distinct feel and sound. Try extra skins in the interactive preview before purchase. Sound, haptics and left-handed layout are adjustable.

FREE AND PRO
Introductory lessons, basic practice, a free abacus, and selected problem-generation and mock-exam options are available free. A one-time Pro purchase unlocks expanded practice conditions, advanced problem generation, PDF worksheet creation and sharing, additional exam levels, and extra skins. There is no monthly subscription.

No account or ads. Practice records are stored on this device.
Now available in Japanese, English, Simplified Chinese, Traditional Chinese and Korean. Screens, all 16 introductory lessons, instructions, purchases and restore, practice history and PDFs follow your app language. Change it directly in Settings > App language inside the app; your choice applies immediately.

### 1.1 — 2026-10-13

Made the Settings skin list lighter to render. List thumbnails now use static images of the real abacus; tap a skin to try bead movement in its interactive preview. Non-interactive boards no longer participate in drag recognition.

Removed the duplicate keyboard-dismiss button in invoice arithmetic. The control is now beside the answer field. Hiding the keyboard preserves your entered answer.

Improved mock exam and generated-practice layouts. The complete abacus and answer controls remain visible with long questions. All problem lines can be read from first to last. Improved compact-screen and large-text layouts.

Reduced resource usage during sustained Free Abacus input. Bead images and touch sounds use bounded shared resources. Improved landscape transitions and initial screen stability.

Switch between five languages directly in the app settings, without restarting. Your choice is remembered after relaunch. Existing problem conditions and generated questions are preserved; PDFs are created in the selected language.

Translated purchase-information errors now clear correctly after the connection recovers.
Now available in Japanese, English, Simplified Chinese, Traditional Chinese and Korean. Screens, all 16 introductory lessons, instructions, purchases and restore, practice history and PDFs follow your app language.

The free abacus now uses a large landscape board and returns to a portrait layout on exit. Improved question generation for repeat sessions and added completion celebrations.
