Go Button vs Soundboard Studio

Go Button is an iOS app for creating and running sound cue playlists for live performances on iPad, iPhone, and iPod touch. It can play several sounds at once, advance through a cue list with the GO button, or trigger ad-lib effects from Hit buttons. Cues may auto-stop, fade, loop, or duck, with separate volume, pan, speed, and pitch controls. Playback accepts iOS-compatible remotes, Bluetooth keyboards and accessories, MIDI input, OSC commands, and hotkeys. Shows can move through AirDrop or the iOS Files app, arrive from iCloud Drive or Dropbox, and be imported into QLab. Supported audio includes WAV, AIFF, AIFC, M4A, AAC, MP3, MOV, CAF, 3GP, MPEG4 audio, and FLAC; copy-protected files are excluded. It requires iOS 15 or later. The free version costs nothing for one saved playlist; the $99.99, paid once Pro License allows unlimited playlists.

Soundboard Studio is an iOS cartwall app for playing audio such as pads, music beds, voiceovers, sound effects and soundbites. It is presented for podcasts, shows and gigs, as well as studio, broadcast and theatre use. Any number of tracks can play at once, with a separate volume control for each. Tracks can be trimmed using a waveform, looped, faded in or out, or set to stop other tracks when played. Automations can play, stop or change the volume of other tracks when a track starts, stops or reaches its end. Audio can be bulk imported from Dropbox, Google Drive, iCloud Drive and other sources. The free version allows up to 24 tracks across four boards, but does not include background playback when the app is closed or track automations. Pro adds unlimited tracks and boards, background playback and automations. The weekly option is $6.99 a week and the yearly option is $59.99 a year; both begin with a 7-day free trial. A lifetime Pro purchase is $159.99 USD. The app is described as universal for iPad, iPhone and iPod touch. Its privacy policy says audio files and track settings are stored locally, and that personal information and analytics data are not collected.
