Go Button vs SoundTools Soundboard

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.

SoundTools Soundboard is a browser soundboard for recording, editing, organizing, and playing audio clips. Users can upload files, capture sound from a microphone, slice waveforms, and assign clips to tappable buttons. It accepts MP3, WAV, OGG, FLAC, AAC, and M4A, and can play multiple sounds at once. Boards save automatically in browser local storage, with an option to export a full board for backup or transfer. There is no fixed sound count, though performance depends on device memory. Audio processing takes place locally in the browser, and sounds are not uploaded to a server. Clips can be exported as WAV, processed with effects in SoundTools Voice Changer, then imported back into a board. The service runs in desktop Chrome, Safari, Edge, and Firefox, as well as on iPhone and Android. Its free plan costs nothing, with no account, installation, watermarks, or limits. Playback comes through speakers or headphones rather than virtual microphone routing.
