DuoBeat is a compact music-making app built around an eight-track drum machine, sampler, and step sequencer. Users can tap in patterns, adjust track controls, build longer arrangements, record or resample audio, and export finished beats in common audio formats. The app includes sound packs, a mixer, MIDI-related tools in Pro, and video clips for sharing performances. It supports iPhone and iPad, with special layouts for iPhone Duo. The developer says the free version includes small ads in the project list and while rendering a clip; DuoBeat Pro is a one-time purchase that removes ads and adds stem and MIDI export, controller input, and other options. The listing does not state the Pro price. Music projects can sync through iCloud, and collaborators can share files or links.
