Learn to recognize chord progressions by ear with real recorded music. ChordProg Ear Trainer has exercises for chord, interval and scale practice, from identifying individual sounds to following a whole progression. Listen to a clip and name the chords in order. Replay a passage when you need another listen, and switch between chord names and Roman numerals to practice recognizing each chord's role in the key. More than 500 recorded clips give you practice across different keys and voicings. Focus on the sounds you want to recognize. Practice telling chord types apart, hearing the distance between two notes or identifying a scale as it plays. Work through short levels and return to the ones you find difficult. Your results and daily streak help you keep track of your practice. When you want to understand what you heard, look it up in the chord, interval and scale dictionaries. You can also tap notes on the piano to find matching chords and scales. Try introductory levels without a subscription. Premium gives you full access to the chord, interval, scale and chord progression exercises through an auto-renewing monthly or yearly subscription.

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.
