Feature-by-feature deep dive
Where each product wins, where each one falls short.
Platform support
OnSong: Apple-only. iPad, iPhone, iPod Touch, and Mac. No Windows version, and the Android app was withdrawn from the Play Store in 2022. For an all-Apple team this is a non-issue; for a mixed team it's a hard wall.
Song7: Any modern browser, desktop or mobile, and installable as a Progressive Web App on iOS, Android, macOS, ChromeOS, and Windows. The volunteer who shows up with an Android phone or a Windows laptop is covered without a second thought.
Individual app or team platform
OnSong: Designed around one musician and their library. It's excellent at that. Sharing across a team is possible through OnSong Connect and Group plans, but it's an add-on to a fundamentally personal app, and individual plans limit you to 2–4 devices.
Song7: Built team-first from the start. One shared song library, setlists the whole team sees, and changes that sync in real time. There's no per-device seat math. Members open it in a browser and they're in.
Song and chord chart management
OnSong: Mature chart handling: ChordPro, PDF chord charts, a document scanner for printed sheets, Nashville number-system display, chord diagrams, and integrations with licensed chart sources like MultiTracks and SongSelect. Playing from a PDF as your stage chart is a real OnSong strength Song7 doesn't match.
Song7: Built-in editing of your own charts. Import from ChordPro or plain text with chord brackets, or snap a photo of a printed sheet and Song7's photo-to-chart OCR turns it into an editable chart (not just a stored PDF). For sheet music, a song can hold MusicXML scores (one per instrument if you like) rendered as staff notation you can transpose, and PDFs or images can be attached and viewed alongside the chart, though they stay stored files rather than editable charts. The library is yours and your team's. Song7 doesn't provide a public database of copyrighted songs.
Setlist creation and planning
OnSong: Supports sets you build on your device. Sharing a set with bandmates runs through OnSong Connect; the planning model is still rooted in the individual's app rather than a shared team plan.
Song7: Drag-and-drop setlist builder is core. Pick songs, reorder by dragging, set the key per song, publish the set, and the whole team sees it instantly, with no per-device syncing step to think about.
Transposition and key changes
OnSong: Strong, fast transposition and capo formatting on a per-device basis. Change the key on your iPad and your chart updates, but it's your copy.
Song7: One-tap transposition into any key, and because the library is shared, changing a song's key for Sunday updates every musician's chart in real time. No "did everyone re-sync?" moment.
Live performance hardware
OnSong: This is OnSong's home turf. Foot-pedal page turns (including AirTurn), programmable autoscroll with a timeline, backing tracks linked to Apple Music or Spotify, audio click and visual metronome, MIDI automation, and DMX stage lighting. For a performance-heavy setup, OnSong goes deeper than Song7.
Song7: Covers the essentials: autoscroll, a built-in metronome, a built-in tuner, and backing tracks or stems your team uploads to a song, played in sync with a per-track mix. It doesn't ship curated foot-pedal hardware or MIDI/DMX automation. If hands-free pedals and stage automation are central to your service, OnSong wins this category today.
Annotations and notes
OnSong: Rich annotation tools on Premium: drawings, clips, and sticky notes layered onto charts. One of its stronger areas for musicians who mark up heavily.
Song7: Each song has a notes section the whole team sees. Heavy free-form drawing on top of a chart isn't the focus. Song7 favors structured editing of the chart itself over overlay markup.
Live presentation and projection
OnSong: Premium includes lyrics projection, stage monitors, and Google Cast output to an external display, driven from an Apple device.
Song7: Has a congregation-facing presentation mode that displays clean, full-screen lyrics on any screen with a browser, and no Apple hardware is required to drive it. Both products can project; Song7 does it without tying you to the Apple ecosystem.
Team collaboration and sync
OnSong: Collaboration happens through OnSong Connect and Group plans with shared OnSong Drive storage. It works, but it's a sharing layer on top of individual libraries rather than a single shared source of truth.
Song7: Real-time team sync is the core model. Multiple editors manage one shared library and setlists, members see published sets instantly, and multi-Space support lets multi-campus churches keep separate teams under one account.
Offline access
OnSong: As a native Apple app, charts are stored on-device and read offline without a thought. This is a genuine strength of a mature native app when the church Wi-Fi drops mid-service.
Song7: As a PWA, Song7 caches content for offline reading, but the offline experience is currently lighter than a fully native app. For situations where rock-solid offline is non-negotiable, OnSong's native caching has the edge.
