Stop forgetting numbers. Start seeing them. majors23 teaches you the Major System — a proven mnemonic technique that converts digits into consonant sounds, which you then turn into vivid words and images. Phone numbers, PINs, dates, historical years, mathematical constants: anything becomes a picture you can't unsee. HOW IT WORKS Each digit 0–9 maps to a phonetic sound. Two digits make a word. That word has an image. Your brain remembers images far better than abstract numbers — that's the whole trick. FOUR TABS. ONE SYSTEM. Reference Browse all 100 number-image-word associations in a 5-column grid. Hide numbers, pictures, or words to self-test. Tap any cell to reveal it. Read aloud with built-in voice playback — hear the number and word spoken together at adjustable speeds. Double-tap anywhere to stop. Generate Type any sequence of digits and instantly see the matching image-word pairs. Perfect for encoding phone numbers, PINs, or constants like Pi and Euler's number. Copy the words or a learning prompt in one tap. Save any sequence with your own visual story sentence for later review. Quiz Test yourself in two directions: Number → Image or Image → Number. Choose multiple choice or type-in answers. Target any range of numbers, drill specific digit combinations with Matrix mode, or let the app automatically surface your weakest numbers in Difficult mode. Quit any time without affecting your stats. Stats Track accuracy and average response time for every number across both quiz types. Sort by any column to spot your blind spots at a glance. FEATURES 100 hand-curated mnemonic images Voice reading with number + word spoken aloud Configurable quiz: range, matrix, or difficulty-based selection Unlimited questions with automatic recycling Persistent stats saved on-device Day and night display modes No account required — everything stays on your device Whether you are preparing for a memory competition, trying to memorize your passport number, or just curious about how memory athletes think, majors23 gives you the full toolkit.
