What if learning music felt like your favourite game? Whether you are picking out your very first note or preparing for Grade 8 theory, MuseSync turns learning music into something you will actually want to open every day: quick games, short lessons, instant feedback, and a score to beat. No instrument needed โ€” everything is played on screen, by ear, or with your voice. PLAY YOUR WAY TO GRADE 8 Five arcade-style games train the skills real musicians drill: โ€ข Note Rain โ€” catch falling notes before they hit the stave โ€ข Rhythm Tap โ€” hold the groove against the metronome โ€ข Melody Echo โ€” hear a phrase, play it back โ€ข Sight Read โ€” read ahead under time pressure โ€ข Sing the Note โ€” pitch it with your own voice, scored by the mic Every round earns XP. Every mistake costs a heart. Every comeback feels great. A GAME AROUND EVERYTHING โ€ข Earn XP for accuracy, not just for finishing โ€ข Keep your daily streak alive โ€” seven days makes a perfect week โ€ข Climb the weekly league against other learners โ€ข Unlock achievements as your skills stack up No account needed. Open the app and play. A REAL SYLLABUS UNDERNEATH This is not trivia. 110 bite-size lessons take you from your first note to analysing a fugue: โ€ข Music Reading (Grades 1-2) โ€” notes, clefs, rhythm, key signatures โ€ข Tonal Harmony (Grades 2-3) โ€” intervals, time signatures, minor keys โ€ข Harmony & Keys (Grades 4-5) โ€” circle of fifths, triads, inversions, cadences โ€ข Advanced Harmony (Grades 6-7) โ€” seventh chords, modulation, counterpoint, fugue โ€ข Score Mastery (Grade 8) โ€” chromatic harmony, orchestral scores, composition โ€ข Professional Practice (Diploma) โ€” teaching, research, career, copyright Work through them in order, or jump straight to the grade you are preparing for. Notation is engraved with the same professional music font used by real scorewriters, so what you learn here is exactly what you will read on paper. LEARN BY DOING, NOT BY GUESSING Lessons end in exercises that make you do the thing, not pick the thing: โ€ข Write notes onto a real stave โ€ข Build chords and progressions by hand โ€ข Identify intervals, chords and cadences by ear โ€ข Tap rhythms in time โ€ข Sing back phrases using your microphone โ€ข Compose short melodies and get instant feedback IT REMEMBERS WHAT YOU FORGET Theory fades if you only meet it once. MuseSync tracks every skill you practise and schedules it to return just before it slips, using a proven spaced-repetition model. Short Refresh sessions revive your three weakest skills โ€” no redoing whole lessons. MADE FOR THE WHOLE FAMILY MuseSync has a dedicated Kids mode. Younger children get a friendly, colourful space with simple ear- and rhythm-training games โ€” Higher or Lower for pitch, Clap Along for rhythm โ€” while grown-ups keep the full Grade 1 to Diploma journey. A parent gate keeps purchases in adult hands. WHO IT IS FOR โ€ข Complete beginners โ€” start from your very first note โ€ข Anyone who tried a theory book and gave up โ€ข Students preparing for a graded exam โ€ข Players who never learned to read properly โ€ข Teachers setting structured practice between lessons โ€ข Families โ€” a dedicated Kids mode for younger children Five minutes a day is enough. Your streak is waiting. Made by Toolbone. Website: https://www.toolbone.com Privacy: https://www.toolbone.com/privacy-policy

Know where you stand in every course. GradeCalc turns your grades into the one number that matters and the exact score you need next. THE ANSWER FIRST Every course card leads with the verdict: the exact score on the final that keeps your target, written in red. A grade ledger shows what is already banked, what was dropped, and what is still in play, with a points-to-spare chip that says how much you can still lose and make it. WEIGHTED GRADES Set up categories like Homework, Quizzes, and Midterms with the weight each carries, log your scores, and watch your real course grade update instantly. WHAT YOU NEED ON THE FINAL Tell GradeCalc your target and it solves the exact score you need on the final exam. It is honest at the edges too: when the target is already secured, or out of reach, it says so. SEMESTER AND CUMULATIVE GPA See your semester GPA and your cumulative GPA across every term, with a per-term trend. Pick the scale your school uses: US plus/minus on 4.0, the 4.3 A+ scale, whole letters, or a credit-weighted percentage. WHAT-IF SCENARIOS Try any score on the final and watch your projected course grade, letter, and semester GPA move in real time. GRADE LAB Preview what happens if a teacher drops your lowest score, replaces a grade after a retake, or asks you to recover across several assignments. Every preview leaves your saved grades untouched. TRACK EVERY COURSE Keep all of your courses in one place, each with its own categories, target grade, and credits. EXPORT Share a semester report PDF or a CSV of every grade straight from the share sheet, ready to print or keep. PRIVATE BY DESIGN No account, no cloud, no tracking. Everything you enter stays on your iPhone. FREE AND PRO Free tracks one course with its weighted grade and the final-score solver.
