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.

Verdict
The clearest difference is price: ScanRenamer at Free against Stereo Microphone's $2.99. Stereo Microphone's advantage is in-app purchases (none vs 1) and update cadence (monthly vs every 3 months). On ads and device support there is nothing between them.
