About Major System Trainer
Turn every number into a picture your brain can't forget. Major System Trainer teaches you the Major System — the classic memory technique that turns digits into sounds, sounds into words, and words into vivid mental pictures. Once every number from 00 to 99 has its own image, memorizing phone numbers, PINs, dates, playing cards, or long strings of digits stops being a chore and starts being a game. HOW IT WORKS Each digit (0-9) maps to a consonant sound. Pairs of digits become words, and words become pictures you actually remember — because a picture beats a string of digits every time. The app walks you through the digit-to-sound rules first, then gives you a complete, ready-to-use set of 100 peg words and images for every number 00-99. TWO WORD SETS TO START Pick whichever clicks with you: a Classic English word set with clean, simple pegs, or a personal photo set using real photos for every number. Switch anytime from the menu, and any word or picture you customize yourself stays exactly as you left it either way. MAKE IT YOURS Don't like a word or picture for a particular number? Change it. Every entry in the 00-99 list can be edited with your own word and your own photo, so the system fits how your memory actually works. TRAIN AT YOUR OWN PACE Flashcard-style drills quiz you both directions — number to picture, and picture back to number — so the association gets locked in from both sides. PUSH YOURSELF WITH CHALLENGES Growing Number: memorize a number that gets one digit longer every round. Timed Run: answer as many flashcards as you can in 60 seconds. Sequence Recall: watch a series of pictures, then reproduce the exact order. Memory House: a fully illustrated house with fifteen rooms, each holding a number — place them all correctly to win, in a visual spin on the classic memory palace technique. TRACK YOUR PROGRESS Every challenge mode keeps a highscore, so you can watch your recall speed and memory span improve over time. Whether you're a student, a competitive memory athlete, or just someone tired of forgetting phone numbers, Major System Trainer gives you a complete, structured way to build a genuinely better memory — one number at a time.
What’s new
Version 1.1.1 · Updated September 21, 2026
New: Flash Memory Challenge — a number flashes for just 1 second, catch it with your peg system before it's gone. Added background music (calm, cinematic ambient loop) with a mute toggle in the header, plus a little sound and animation on every correct or wrong answer. Challenge games now flow faster — after your first round, "Continue" jumps straight into the next one instead of showing the instructions again every time. Fixed a couple of layout issues where content could overflow the screen (Training and Sequence Recall). Fixed a bug that could prevent saving a custom picture for a peg word, and a rare crash on launch.
