Every Feature Inside Abacus Kids

Not a shortcut app — a complete abacus curriculum with the practice tools, exams and games that make it stick. Here is exactly what your child gets.

Interactive Abacus

A real, touch-responsive abacus. Move beads with a finger, exactly like the physical tool.

  • Choose a 7-rod or 13-rod abacus (the 13-rod adds decimal places)
  • Left-hand mode for left-handed children
  • Bead sound effects and configurable bead direction
  • Free Mode: explore and set any number with no task attached

Guided Learning Path

Four levels from the very first bead to mental math — Learn, Practice, Quiz in every lesson.

Explore the Learning Path
  • Level 1 Bead Basics (ages 4–6) — 5 lessons, completely free
  • Level 2 Add & Subtract (ages 6–8) — 10 chapters covering Small Friend, Big Friend and Family formulas, chapters 1–3 free
  • Level 3 Speed & Anzan (ages 8–10) — 5 mental-math modes including a timed Speed Drill and a 4-tier Flash Challenge
  • Level 4 Times Tables (ages 10+) — every table from ×1 to ×20 with read-aloud learning, drills, flashcards and fill-the-blanks, tables ×1–×3 free

Abacus Practice — 8 Levels

Structured drill: 8 levels → pages → sets, with 20 abacus problems in every set.

  • Progresses from single-digit addition to multi-digit subtraction, formula work, multiplication and division
  • Step by Step sets — formula hints and bead-direction arrows at every step
  • Final Answer sets — set the whole sum on the abacus, then submit
  • Formal Exam sets — scored, and the result is saved so you can see it immediately and any time later in your history
  • Some sets include a timer option to build speed
  • Level 1 is free, Level 2 is partly free (first 20 pages), Levels 3–8 are Premium

Exam Mode

Addition, subtraction, multiplication and division exams at three difficulty levels.

  • Three question types, including four-option multiple choice
  • Abacus-image questions: read the beads and pick the value
  • Addition exams at Beginner difficulty are free — all others are Premium

Exercise Mode

Fast repetition with different digit counts and line counts, answered on the abacus or a keypad.

  • Multiple digit-count and line variants for addition and subtraction
  • Every result saved with time, score and date
  • The first two variants of addition and subtraction are free

Custom Challenge Mode (Anzan Training)

Build your own mental-math workout — the closest thing to an abacus competition on a phone.

  • 1 to 4 digit numbers, with flash gaps from 0.5 to 3 seconds
  • Numbers spoken aloud, shown on screen, or both
