NEW: 6-STEM SEPARATION OffgridStem now separates Vocals, Drums, Bass, Guitar, Piano, and Other — not just the standard 4. Study a guitar riff note-for-note, isolate the piano part, or build a cleaner instrumental than ever. NEW: LIVE REACTIVE VISUALIZER Your exported mixdowns now live in a dedicated Exports player with a real-time, audio-reactive waveform — 14 visual styles (Bars, Neon Glow, Glass, Siri-style Fluid, Circular, Retro EQ, Cassette, and more) and 4 color themes. Turn your phone sideways for an immersive fullscreen view. NEW: PITCH & TEMPO IN YOUR EXPORTS Shift the key, slow down the tempo to learn a part — your exported mixdown now matches exactly what you heard, not the original.

Verdict
The clearest difference is in-app purchases: Songbook LS at none against Stem Splitter's 1. Songbook LS also leads on update cadence (every 4 days vs weekly). Stem Splitter's advantage is iOS requirement (17.6 vs 26.2). On price, ads and device support there is nothing between them.
