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.

本アプリは、iPhone専用アプリです。 iPhoneとM5Stackの超小型マイクスピーカーユニット AtomEcho 間で音声通話ができます。 ・使い方 AtomEchoと通信ができるとマイクマークが青色になります。 マイクマークを押すと赤色になり、話した音声をAtomEchoに送信します。 AtomEchoでは、受信した音声をスピーカーから再生します。 AtomEcho側でボタンを押して話すと音声が送信されて、このアプリで受信されます。 音声を受信すると、スピーカーマークが緑色になり音声が再生されます。 AtomEchoとiPhoneは、同じネットワークに接続されている必要があります。 AtomEcho側のプログラムは、GitHubから入手出来ます。 https://github.com/ayamasan/AtomTalk

Verdict
The clearest difference is price: AtomTalk at Free against Stereo Microphone's $2.99. Stereo Microphone's advantage is update cadence (monthly vs every 27 months) and device support (3 vs 1). On ads and in-app purchases there is nothing between them.
