JamJar keeps your whole song collection in one place: sheet music, chord charts and lyrics, organized, searchable and synced across iPhone, iPad and Mac through your own iCloud. As a hobby musician, my music was scattered everywhere: PDF books, tunes from public-domain archives, photos of pages off my shelf and several music apps. Finding a song again was harder than playing it, so I built JamJar to be one shelf for all of it. NEW: TURN A SCAN INTO SHEET MUSIC YOU CAN EDIT • Convert to Sheet Music (ABC) reads a printed page, scan or PDF and writes it out as a new song you can edit, transpose and play back • Bars it isn't sure of are flagged for you to check against the original, which stays untouched beside it • Runs on your device, offline, after a one-time download of about 1.6 GB • Works best on printed single-staff music such as lead sheets, fake books and tunebooks. Handwritten pages are unreliable, and lyrics aren't read • Needs a device with plenty of memory. On others the command is hidden and the rest of JamJar works as usual NEW: WRITE MUSIC ON THE SCORE • Tap a note to change its length, accidental or pitch, or drag it up and down the staff • Enter notes from an on-screen piano, or type them on a keyboard without writing any ABC • Add chord symbols, ties, triplets and other tuplets, repeats and endings, D.C. and D.S. marks, articulations and dynamics • Hear every note as you enter it • Full bars close themselves, and bars that don't add up are flagged • The score and its ABC source stay in step, so you can edit whichever is quicker BRING YOUR OWN MUSIC • Import single songs or whole books as PDFs and images • Scan paper books with the camera on iPhone or iPad • Split a scanned book into separate songs automatically, titled for you • Search open tune archives, or describe the tune you're after in your own words • Open files from the apps you already use: ChordPro, ABC, OnSong, OpenSong, iReal Pro and MusicXML PRACTICE WITH A BACKING BAND • Hear ABC, MusicXML and iReal Pro charts played with melody, chords, bass and drums, in a groove that suits the tune • Fade each part on the mixer, or pull one out and play it yourself • Loop a tricky passage, with a metronome and count-in ON STAGE WITH PERFORMANCE MODE • One chart, full screen, with the screen kept awake • Turn to the next song with a swipe, the keyboard or a Bluetooth page-turn pedal • Editing is locked, so nothing changes by accident mid-set • Build set lists and share them with your bandmates CREATE, EDIT AND ORGANIZE • Write songs as lyrics and chords (ChordPro), sheet music (ABC) or chord charts • Transpose to any key • Draw and highlight on your sheet music • Tag, search and filter your library • Ask about a song in plain language, or ask for changes such as tidying the chords, powered by Apple Intelligence • Automate with Siri and Shortcuts • Private sync through your own iCloud: no account, no sign-up JamJar speaks English and Swedish, with more languages on the way. Whether you're rehearsing, teaching or on stage, JamJar keeps every song ready to play. ## Is JamJar safe? Not enough ratings yet to assess JamJar. ## Is JamJar legit?

Here's what's new: Convert to Sheet Music (ABC) reads a printed page, scan or PDF and writes it out as a song you can edit, transpose and play. Bars it isn't sure of are flagged for you to check against the original. It runs on your device after a one-time download of about 1.6 GB, on devices with plenty of memory. ABC songs have one editor for the score and the source. Tap or drag a note to change it, enter notes from an on-screen piano or your keyboard, and add chord symbols, ties, tuplets, repeats and endings, articulations and dynamics. Every note plays as you enter it. Search Online takes a description in your own words with Apple Intelligence, and tries the other sources when the ones you picked find nothing close. New Song asks what kind of song you want, and can start a blank tune or a blank iReal Pro chord chart. iReal Pro charts have an Open in iReal Pro button. ABC files show previews and thumbnails in Finder and Files. Long ABC tunes can wrap to 4 bars per line, in Settings. The Mac menu bar is reorganized, and toolbar buttons show their shortcuts. Swipe-deleting a playlist no longer crashes, and ABC tunes without a tempo number, or with one typed in the inspector, no longer play twice as fast. Thanks for playing along, and keep the feedback coming! ### 1.0.1 — 2026-10-03 This one is mostly about fixing things. Here's what changed: Songbook imports are faster and split into songs more reliably. Titles made of several pieces, fake books, faint old scans and recording credits are handled better, and a single-song PDF now comes in as one song instead of one song per page. iReal Pro editing and rendering improvements. Dragging songs around in a playlist no longer gets stuck. ChordPro songs can auto-scroll, and chords on lines with hyphenated lyrics show up in the right place. Temporary files are cleaned up properly, so JamJar takes less disk space over time. Thanks for playing along, and keep the feedback coming! ### 1.0 — 2026-09-22 No release notes. ## Apps similar to JamJar | App | Rating | Price | Category | | --- | --- | --- | --- | | [Score Master: Music PDF Reader](https://appshunter.io/ios/app/score-master-music-pdf-reader/id6769524427) | — | $9.99 | Music | | [NNS Pro](https://appshunter.io/ios/app/nns-pro/id6792365943) | — | $17.99 | Music | | [JamEngine](https://appshunter.io/ios/app/jamengine/id6759828737) | — | Free | Music | | [Achordy](https://appshunter.io/ios/app/achordy/id6742419870) | — | Free | Music | | [UltimateScale](https://appshunter.io/ios/app/ultimatescale/id1631310626) | — | Free | Music | | [Musync - For Musicians](https://appshunter.io/ios/app/musync-for-musicians/id6744175259) | 5.0 (5) | Free | Music | ## Related topics [jam jars](https://appshunter.io/ios/topics/jam-jars) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
