A sketchpad for music, for practice and for composing. Notes go in on a keypad as quick as a calculator, and play back exactly as written. FOR PRACTICE Copy out what you're learning: an exercise, a few difficult measures, the piece your teacher assigned. Hear how it should sound, then slow it down, loop it, and raise the tempo as you improve. Pianists can write both hands on a grand staff, and choirs can write out all four parts and hear them together. Check your rhythm counting or your harmony homework by ear. The keypad is simple enough for children to use, and the selected note's name, such as F#, shows on its key as you write. FOR COMPOSING Write down a melody, a chord progression or a four-part harmony before you forget it, and hear every part played back with real instrument sounds. Use one instrument or several, with up to four voices on each staff, and keep every idea in your library. HOW IT WORKS Tap a note value to add a note, drag up or down to set its pitch, and drag sideways for sharps and flats. The keys are large, so there are no toolbars of tiny icons and no stylus. WRITE IT • Notes and rests from double whole notes to 128th notes, with up to three dots • Chords, and up to four voices per staff, each in its own color with stems placed for you • Several parts, each with as many staves as it needs: a piano grand staff, SATB on two staves, a duet, a small group • Treble, bass, alto and tenor clefs, with clef changes anywhere • Every key signature, chosen from an interactive circle of fifths, with key changes anywhere • Simple and compound time signatures, and a pickup measure where a piece starts with one • Ties, accidentals, staccato, accents and tenuto • Triplets, quintuplets and nested tuplets • Automatic beaming HEAR IT • Precise playback in pitch, rhythm and tempo, looping continuously • Long-press play to set the tempo, from 30 to 240 BPM, even while the music plays: slow a passage down as far as you need, then raise the tempo as your playing improves • 25 instrument sounds, from grand piano and harpsichord to strings, brass, woodwinds, harp and guitar • Two metronome channels and a volume for every part • The score glides along as it plays and each note lights up as it sounds KEEP AND SHARE IT Every passage is saved to your library and named for you. Import MusicXML (.musicxml, .xml, .mxl) from other notation apps, with its notes, rhythms, keys and clefs, and export MusicXML to finish a piece in desktop notation software. Built for iPhone, one-handed, and for iPad, with a full-width keypad and a library sidebar. Pinch or double-tap to zoom. There are no ads and no account to create, and your music stays on your device. WHAT IT ISN'T Music Calculator is built for short passages and ideas, not symphonies. It doesn't do dynamics, slurs, lyrics or chord symbols, print or export PDFs, export audio or MIDI, or scan sheet music. If you need those, a desktop engraving program is the right tool. If you want to write a passage down and hear it in seconds, this is.

Needs improvement on tedious articulation settings and paywall *2026-10-08* this app was great. I would definitely use this more if there was not a limit on how many times I could play the rhythm. One complaint I have with this app is that I found it very difficult and incredibly tedious to have to continuously swap from one articulation to the next by holding down than tapping and pressing done and then rinse and repeat **Developer response:** Thank you for your honest review! We really appreciate you taking the time to provide valuable feedback. Just to let you know that we have an update coming in the next few weeks that vastly improves the very issue you describe. It also contains a LOT of other new features! We're very excited about it. ### 5/5 — Brilliant for Sight Reading! *2026-03-30, version 3.0.2* I learned to read music when I was younger, but then went many years without practice and forgot a lot of it. This app has been brilliant helping me re-learn to sight read, especially when I get stuck with tricky passages! My 8 year old son now also uses it as he’s just started having keyboard lessons, and he finds it easy to use. ### 5/5 — A really useful app *2026-03-28, version 3.0.2* Yet another great app from Jet Powered Apps. ## Frequently asked questions about Music Calculator ### How does Music Calculator help with practicing difficult music?

Everything in your library is kept. ### 3.3.0 — 2026-09-16 We have added the ability to add accidentals to a note by dragging the selected note button sideways. Left to flatten the note, right to sharpen the note. It's context aware so deals with naturals correctly. We've also added new visual indicators to the selected note button to better highlight the available functions. Changing pitch and accidentals from the button feels so natural that we've removed the ability to drag notes on the stave. All in, this helps to massively speed up entering a more complicated passage of music! Happy practicing! ### 3.2.1 — 2026-06-18 Minor bug fixes ### 3.2.0 — 2026-06-12 Added localisations ## Apps similar to Music Calculator | App | Rating | Price | Category | | --- | --- | --- | --- | | [Rhythm Training](https://appshunter.io/ios/app/rhythm-training/id1613734367) | 4.5 (50) | Free | Music | | [Dorico - Compose Music](https://appshunter.io/ios/app/dorico-compose-music/id1556625090) | 4.6 (2,246) | Free | Music | | [iReal Pro](https://appshunter.io/ios/app/ireal-pro/id298206806) | 4.9 (11,150) | $21.99 | Music | | [Functional Ear Trainer](https://appshunter.io/ios/app/functional-ear-trainer/id1088761926) | 4.9 (3,825) | Free | Music | | [PlayScore 2](https://appshunter.io/ios/app/playscore-2/id1449591118) | 4.1 (4,757) | Free | Music | | [forScore](https://appshunter.io/ios/app/forscore/id363738376) | 4.8 (43,440) | $24.99 | Music | ## Related topics [music calculator](https://appshunter.io/ios/topics/music-calculator) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
