Split any song into 6 isolated stems on your iPhone — vocals, drums, bass, guitar, piano, and other. Nothing uploads. Nothing waits in a cloud queue. No subscription required. StemLab runs the AI separation entirely on your device, then opens a full multi-track mixer with studio FX, A/B looping, recording, and stem export. Built for musicians, producers, and singers who want clean, isolated stems without monthly fees. SEPARATE Imports MP3, WAV, FLAC, M4A, even MP4 and MOV video — up to 500 MB per file. Pick a 4-stem or 6-stem AI model to extract vocals, drums, bass, guitar, piano, and more in a single pass. Works as a vocal remover, instrumental maker, acapella extractor, karaoke track maker, and backing track creator. Everything happens on your iPhone — your music never leaves the device. MIX A real multi-track mixer, not just a separator. Per-stem volume, solo, mute. Set A/B loop points to slow down a solo, transcribe a phrase, or rehearse the chorus on repeat. Scrub the timeline with centisecond precision and watch live waveforms render in real time. CHOP & SAMPLE Pull a clean drum break, lift a vocal chop, or grab a bass line for a lofi beat. Isolate any stem, loop the exact bars with A/B points, and export it as a WAV sample ready to flip in your sampler or DAW. MAKE IT YOURS Record your own vocal over the instrumental, lay down a guitar take on top of the AI bass, or import any audio file as a custom layer. Build mashups, track covers, write demos, replace a stem entirely — all inside one session, on your phone. ADD EFFECTS Shape each stem with a 6-effect chain: Pitch Shift, Reverb, Delay, Compressor, 4-band EQ, and Saturation. Run Bus FX on the master mix. Bypass any effect without removing it. Save your settings as a reusable preset and load them on the next song with one tap. EXPORT Send out individual stems or a new stereo mixdown in WAV, FLAC, or M4A — now baked with your FX chain, so your Pitch Shift, Reverb, Delay, Compressor, EQ, and Saturation settings carry straight into the export. Pick your sample rate (44.1 / 48 / 96 kHz) and bit depth (16 / 24 / 32-bit). Drop the result straight into your DAW, sampler, looper, or any other app. Built for guitarists isolating solos, bassists transcribing lines, beatmakers pulling clean acapellas, DJs making edits, music teachers building practice tracks, worship leaders covering for missing players, and singers laying covers over original songs. ---------- StemLab Pro unlocks unlimited separations, individual stem export, the full FX chain, and unlimited presets. Available as a one-time lifetime purchase — buy once, keep what you bought. Yearly subscription option also available.

Verdict
The clearest difference is rating: Choons at 5.0 against StemLab's 4.5. Choons also leads on review sentiment (100% vs 67%) and iOS requirement (15.1 vs 26.2). StemLab's advantage is ratings volume (29 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Choons holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: StemLab has 29 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of Choons's written reviews are positive against 67% of StemLab's.
