Read full descriptionHide full description
Lyrics and chords, in one notebook your whole band shares. SongNote is the world's simplest songwriting notebook - no sheet music, no MIDI, just lyrics and chords. It feels like writing in a paper notebook, so you can jot down words and chords the moment they come to you. Share a song with your bandmates, and when anyone changes a lyric or a chord, it shows up on everyone's screen right away. Shape the "let's change this part" moments from the studio together. WRITE TOGETHER AS A BAND • Real-time sharing: edits reach everyone's screen in seconds • Comments and @mentions: leave notes like "break here" under any line, notify bandmates, and react with emoji • Invite by username, QR code, or link, and show the chart in a browser to bandmates without an iPhone • Keep writing even with a weak signal in the studio; changes sync when you're back online WRITE • Place chords above lyrics with a tap - they follow along when you edit the words • Sections (Verse, Chorus...), line reordering, undo and redo • Set the song's key and transpose all chords at once • Lyrics and music credits PLAY • Performance mode with large, easy-to-read text and auto-scroll matched to the BPM • Guitar chord diagrams SongNote 2.6.0 adds My Note, a binder for your song ideas, and Read, one songwriting column a day.

A songwriting notebook that quietly stays by your side while you and your band make music.

Every guitar practice tool is included: tuner, metronome, chord handbook, and a personal songbook. No subscription, no account, and no catalog paywall. OpenString is built for guitarists who want the tools on their phone, not a rented song library. Install it from the App Store. You get the tuner, metronome, chords, and songbook. There is nothing left to unlock later. WHAT YOU GET Guitar tuner Tune a standard six-string guitar with the microphone. Choose a preset, let the app pick the string or choose it yourself, and play a reference note when you want a target pitch. Audio is processed on your iPhone. It is never recorded or uploaded. Metronome Keep time from 40 to 240 BPM. Tap a tempo, set the meter, choose subdivisions and accents, run a practice timer, or mute the click and follow the beat visually. Chord handbook Look up common major, minor, and seventh fingerings in standard guitar tuning. Search the handbook, save favorites, hear a reference voicing, and jump to alternate positions on the neck. Personal songbook Keep your own lyrics and chords. Transpose the displayed key and save a capo preference without rewriting the source chart. Add song metadata, build named setlists, practice with autoscroll, jump to chords used in a song, and import ChordPro. Create and edit on your phone, then export a backup to a destination you choose and restore it later. Song to chords Pick a song and get its chords and words together in one tap, ready to play and sing. Scale and shape finder Type a scale like A minor pentatonic and see its box shapes on the neck, with the fret positions you actually play them in. HOW THIS IS DIFFERENT There are no in-app purchases and no subscription. Every current tool is included with the app. The tuner, metronome, chord handbook, and songbook are not split across plans. No commercial song catalog is included. Your songbook is filled by you, whether you type it or import ChordPro. That is the point: your charts, your lyrics, your practice. The app works offline and needs no account. No feed. No ads in the app. WHO IT IS FOR Players who want a tuner, metronome, chord diagrams, and their own charts in one place. People who write songs, type lyrics and chords they already play, or import ChordPro. WHO IT IS NOT FOR OpenString does not rent you a library of popular songs or official tabs. If you want a commercial catalog behind a monthly plan, this is not that app. OpenString is built for guitar practice on iPhone.

Verdict
The clearest difference is in-app purchases: SongNote at none against OpenString's 1. SongNote also leads on device support (4 vs 2). OpenString's advantage is update cadence (daily vs every 4 days). On price, ads and iOS requirement there is nothing between them.
