Boom Lab vs Play Jazz

Boom Lab is a futuristic mobile music creation app for building beats, mixing tracks, recording original sounds, and organizing project ideas on your device. Start in Beat Lab with glowing pads, BPM controls, loop recording, quantize, swing, and a collapsible mini synth keyboard. Move into DJ Lab to load two decks, blend tracks, scratch virtual vinyl, adjust deck volume, and save sample ideas back into your crate. Stem Lab tools provide the interface for vocals, drums, bass, and instrumental separation workflows as the app evolves. Boom Lab is designed around local device storage. Saved projects, sample metadata, and recorded sounds are kept on your device so you can keep working smoothly and offline. Current features include: - 4-pad beat machine - Loop recording controls - BPM, swing, and quantize controls - Collapsible mini piano synth - Landscape-style DJ mixing board - Two deck import and playback controls - Virtual vinyl scratch interaction - Sample crate for saved sounds - Original sound recorder - Stem Lab placeholder workflow - Saved project vault - .boom project export and import - Device-first offline workflow Boom Lab is free with ads. The only paid upgrade is Boom Lab Premium, which removes ads. Core creation tools are not locked behind a paywall.
