GMApp is a professional audio sampler and timer for game masters, tabletop RPG sessions, murder mystery events, theater, rehearsals, streaming, and live event operation. It helps you trigger music and sound effects at the right moment, organize large sound sets by scene, and run sessions from a clean mobile interface. Designed for live use Run background music, one-shot effects, ambience, scene transitions, and timing cues from one iPhone or iPad. GMApp is built for hosts and operators who need quick, confident control during a performance or session. Who it is for - Murder mystery and story game hosts - Tabletop RPG GMs and keepers - Theater, rehearsal, reading, and small-stage sound operators - Streamers and event hosts who need reliable BGM and SFX playback - Creators managing many audio files across multiple scenes Core features 16-pad soundboard with up to 100 pages Each page provides a 4 x 4 pad layout. Create up to 100 pages, for a total of 1,600 pads, and organize sound cues by scenario, chapter, act, location, battle, or scene. Flexible playback modes Choose the right behavior for each pad or session: - Polyphony: layer ambience, BGM, and sound effects together. - Monophonic: switch cleanly between single sound sources. - Crossfade: transition naturally between music tracks, with adjustable fade time. Tap behavior can also be set to retrigger from the beginning or toggle pause/resume. Detailed pad customization Customize each pad with a display name, color, loop setting, and gain level. Color-coded pads and clear names make it easier to operate under pressure during a live session. Fast audio import Import local audio files from the iOS share sheet, Google Drive, Dropbox, or ZIP archives. This makes it easy to prepare a full show, session, or scenario audio set in advance. Bluetooth speaker keepalive option For long quiet scenes, optional wireless speaker keepalive playback can help reduce the chance of Bluetooth or AirPlay speakers sleeping between cues. Fullscreen timer for sessions and events Use stopwatch or countdown mode, from short scene timers to long event blocks. Fullscreen mode makes the timer easy for everyone at the table or in the room to see. Backup and sharing Export and import page-level ZIP packages and full backups. Move setups between devices, preserve a production-ready sound board, or share cue structures with another operator. Audio formats AAC, AIF, AIFF, CAF, FLAC, M4A, MP3, OGG, and WAV are supported. Compatibility may vary by device and OS. GMApp is made for creators who want the story, scene, or performance to flow without fighting the sound board. Legal notice: https://gmapp.souko.work/tokusho
