Foundry is a sampler for producers who want to get right to chopping. Import a track from Files, and Foundry finds the tempo, key, and downbeat automatically. Slice it on a beat grid with draggable markers, audition each slice, and retune or restretch it to your project tempo, repitch for that classic sampler feel, or stretch to keep the key. Then play. Sixteen velocity-sensitive pads, a count-in, and a loop of any length. Arm, record, and your performance lands on a timeline where you can nudge hits, quantize them to a grid with adjustable strength, and bounce the result to a WAV in Files. CHOP • Automatic BPM, key, and downbeat detection • Beat-grid slicing with draggable markers and a minimap • Loop finder that confirms the grid on tricky tracks • Per-slice pitch, type, and length editing • Repitch or time-stretch slices to follow the project tempo • Project-wide transpose PADS • 4×4 pad grid with a scrolling waveform playhead • Adjustable loop length and count-in • Arm + record transport TIMELINE • Every hit recorded as a dot on its lane • Drag single hits or whole groups • Quantize grid and strength • Bounce takes to WAV, share to anywhere Sessions save automatically and pick up where you left off. Everything runs on-device - no account, no upload, no tracking.

Verdict
The clearest difference is ads: TXT sampler at none against Foundry's shown. Foundry's advantage is update cadence (every 4 days vs every 9 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
