Use your iPhone/iPad as a microphone and output sound to headphones or speakers. You can also use it to record audio instead of playing sound. The app comes with four built-in effects. Stereo input is available on compatible devices only. The microphone on the iPhone is positioned vertically, so by using it in landscape orientation, you can experience a greater sense of stereo sound. Please note that this app was created just for my personal use, and I cannot guarantee its performance on devices I do not own. Voice preprocess: - System Voice Processing - Noise Reduction - Auto Gain Control Included effects: - Pitch shifter - Chorus - Reverb - 10-band equalizer Supported devices with stereo input (unconfirmed): - iPhone XS or later - iPhone SE 2nd generation or later - iPad Pro 11-inch 1st generation or later - iPad Pro 12.9-inch 3rd generation or later Recording file formats: - MPEG4 AAC 44.1kHz 192kbps Stereo (.m4a, Up to 24 hours) - MPEG4 AAC 44.1kHz 128kbps Stereo (.m4a, 24h) - MPEG4 AAC 48kHz 192kbps Stereo (.m4a, 24h) - MPEG4 AAC 48kHz 256kbps Stereo (.m4a, 24h) - MPEG4 AAC 48kHz 320kbps Stereo (.m4a, 24h) - MPEG4 AAC 44.1kHz 96kbps Stereo (.m4a, 24h) - MPEG4 AAC 32kHz 64kbps Stereo (.m4a, 24h) - PCM 44.1kHz 16bit Integer Stereo (.wav, 6h) - PCM 48kHz 16bit Integer Stereo (.wav, 6h) - PCM 44.1kHz 32bit Float Stereo (.wav, 3h) - PCM 48kHz 32bit Float Stereo (.wav, 3h) * You can add a timecode when you use a PCM format.

Verdict
The clearest difference is price: BOOKSCAN SWITCH at Free against Stereo Microphone's $2.99. Stereo Microphone's advantage is update cadence (every 6 weeks vs every 4 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
