Apple is encouraging users to use Voice Memos and GarageBand:
Use Voice Memos to quickly capture your ideas on your iPhone, iPad, Mac or Apple Watch. And with GarageBand, you can take your recordings even further with powerful music creation tools.
The Music Memos app won’t be updated after Music Memos version 1.0.7, and you won’t be able to download it after March 1, 2021. If you have an iPhone with iOS 14 or an iPad with iPadOS 14, you can continue to use Music Memos. And if you’ve previously downloaded the app, you can still access it from your App Store purchase history. But you should export your Music Memos recordings to your Voice Memos library to make sure you keep all of your recordings.
Anyone out there surprised?
