zensoundlab vs PocketChop

Your own audio therapy. ZenSoundLab generates binaural beats, noise colours and pure tones in real time, and lets you layer them into a session you control down to the hertz. WHAT YOU CAN BUILD • Binaural beats from 0.5 to 40 Hz across the Delta, Theta, Alpha, Beta and Gamma bands, on a dial that gives the low frequencies the room they need • Noise in white, pink, brown, blue and violet — or shape your own spectrum • Pure tones, and rising or falling Shepard tones • Stack as many layers as you like, each with its own level SESSIONS TO START FROM Focus, Deep Sleep, Relaxation, Study Session, Settling, Paced Breathing, Alternating Pan, and the plain noise colours. Load one, then change anything about it. THE SLEEP TIMER Set it and the session winds down over its final 30 seconds rather than stopping dead. It runs on your Lock Screen and in the Dynamic Island, counting down on its own, with a pause button that works without opening the app. VISUALS, IF YOU WANT THEM Four generated visuals that respond to what you are actually hearing, or your own looping video. Or turn them off entirely. FREE, AND SELLING YOU NOTHING Apps in this category commonly charge around $60 a year. ZenSoundLab is free. No subscription, no in-app purchases, no ads, and no data collection of any kind — there is no account and no analytics. Binaural beats need headphones to work, and the app tells you when they are required.

PocketChop allows you to catch sounds and turn them into loops. Load a song (or record a sound), slice it into chops, and play them instantly on a 16-pad grid. Record patterns with a built-in sequencer, shape every pad with attack, release, filter and level, and add delay, reverb and pitch — all in a fast, focused interface designed for the way you actually make beats. Features: • Waveform chopping — drag to slice, pinch to zoom, up to 16 chops per sample • 24 velocity-fast pads with per-pad ADSR, low-pass filter, level, delay, reverb and pitch • Record your full mix to M4A, or capture raw audio with the built-in field recorder • Sessions — save your chops, patterns and settings and pick up where you left off • MIDI & Bluetooth connectivity: use your physical MIDI device to play • Scenes: save multiple sequences and chops from the same sample, choose the best • Export individual chops as audio files • Dark and light themes • Built natively for iPhone and iPad No account. No subscription. Audio stays on device.
