DrumShell vs RhythmForge

DrumShell turns any song into a private drum practice rig. Drop in a track. In about three minutes, the drums come out clean — ready to slow down, loop, and drill against. Built for drummers who practice with sticks in hand and a kit in the room, not for casual listeners. — THE INSTRUMENT — • Isolate the drums from any song. Practice along with the kit alone, or mute it and play the part yourself. • A-B Loop. Drag two markers on the waveform and lock onto the bar that's been beating you. Loop tight, drill loud. • Variable speed, 0.7× to 1.5×. Pitch stays musical. Slow down a fill and walk it back up. • Multi-stem mix. Solo the drums, mute them, or balance every stem independently — bass, vocals, other. • Metronome locked to the song's BPM. Auto-detected during separation. • Offline-first. Once a song is loaded, no network needed. Practice in the basement, the green room, or the back of a van. — BUILT LIKE GEAR, NOT A TOY — Hardware-studio aesthetic. Dark chassis, indigo readouts, JetBrains Mono on every readout. Oversized touch targets so you can hit them with a stick in your hand. No tutorials, no upsell modals between you and the next loop. — FREE — • 3 separations per week • Up to 5 saved projects • 2-stem mode (drums + everything else) — PRO ($7.99/month or $49.99/year) — • 25 separations per week • Unlimited saved projects • A-B Loop • Waveform zoom • 4-stem and 6-stem modes (drums, bass, vocals, other — plus extended HD stems) — WHO IT'S FOR — Intermediate to advanced drummers drilling specific passages. If you've ever wished a song had no drums so you could play the part yourself — or wished it had only drums so you could shadow the part — this is the tool.

Most metronomes just count. RhythmForge listens back. Play along to the beat and the app hears you in real time. Every hit is measured, every drift is shown, every session tells you exactly where your timing is strong and where it's not. Your phone becomes a practice coach. HOW IT WORKS Pick a challenge. Set your tempo. Play. RhythmForge scores every beat across six accuracy tiers — Perfect, Great, Good, Okay, Weak, Missed. Build combos with consecutive Perfects for bonus points. Beat your personal best. See exactly where you rushed or dragged. 40+ built-in challenges spanning rudiments (singles, doubles, paradiddles, flams), grooves, world rhythms (tresillo, son clave, rumba, cáscara, bossa nova), and odd subdivisions. From first-week beginner to serious drummer.

What's metered is time: 6 minutes a day, topping back up as the day goes — four times faster while you're practicing. Run out and any challenge still gives you a free 25-second run, as many as you like. Tempo ramp and ghost measures are premium features in competing apps. Here they're free, forever. The metronome you'd pay for, included.
