Full description
Mnemo is a number memory trainer built on a real memory technique: the Major System (also known as number pegs). Every two-digit number from 00 to 99 maps to a vivid image, so you stop memorizing raw digits and start remembering pictures. Unlike generic brain training apps, Mnemo teaches you a transferable skill you can use for phone numbers, dates, passwords and study material - then drills it with 5 focused memory games. HOW THE MAJOR SYSTEM WORKS The Major System turns digits into consonant sounds (1 = t/d, 2 = n, 3 = m...), and each 00-99 pair becomes a word and a picture: 49 = sailboat. To memorize 6 digits, you chain 3 images into one short story. Mnemo ships a ready-made image for all 100 codes and lets you swap in your own. WHO IT IS FOR • Students memorizing dates, formulas and vocabulary. • Professionals who need to hold numbers, PINs and passwords in mind. • Anyone training for memory sports, mental math or sharper focus. FEATURES • Matrix Memory - Watch a 3x3 digit grid, then recall it cell by cell with image-assisted hints. • Grid Blitz - Fast image recognition and reaction training under time pressure. • Chain Sprint - Convert a stream of digits into images and back again, level by level. • Pair Match - Find the matching pairs of 6 encoded cards in as few moves as possible. • Code Book - Browse all 100 number codes (00-99) with images and association hints, and customize your own. GAMEPLAY PROGRESSION • Earn XP and level up through Novice, Apprentice, Pro, Master and Legend. • Complete Daily Challenges to claim rewards. • Keep your training streak alive with daily practice. LEADERBOARDS (OPTIONAL) • Sign in with Google Play Games to compare your best scores with friends and the world. You can play entirely without an account. WORKS OFFLINE • All 5 game modes run without an internet connection and without sign-up - perfect for commutes, flights and study sessions. Your training data stays on your device. PRIVACY • Your game progress is stored only on your device: no account required and no upload of your training data. Start with 00-99 today and turn numbers into images you will not forget.
