Know when songs disappear, details change, or favourites get a Spatial Audio upgrade. Music Library Tracker automatically monitors the music library on your iPhone or iPad, keeping a history of additions, deletions, and changes. Whether you use Apple Music, iTunes Match, or music you've synced yourself, you can see what's happened to the collection you've spent years building. SEE WHAT CHANGED Spot songs that have been added or removed, then explore the details. Compare previous and current information to see exactly what's different, from a renamed album to a changed artist or release year. Track changes to titles, artists, albums, album artists, genres, release years, ratings, disc numbers, track numbers and Spatial Audio status. REDISCOVER YOUR FAVOURITES IN SPATIAL AUDIO Find out which songs in your library have been upgraded to Spatial Audio, including Dolby Atmos and Dolby Audio. Browse your upgraded tracks and let Music Library Tracker create an Apple Music playlist that updates automatically as more upgrades are found. Get an optional daily notification when new upgrades are found. FOLLOW THE HISTORY OF YOUR LIBRARY Browse changes by day, filter additions, deletions, and updates, or open a track to follow its individual history. See when a song was added, what changed along the way, and whether it was later removed. Tracking starts with your first scan, building a history from that point onwards. GET THE UPDATES YOU CARE ABOUT Receive an optional morning summary of changes detected the previous day. Choose whether it includes added, changed, or deleted tracks, so you can focus on what matters to you. MADE FOR YOUR IPHONE AND IPAD Enjoy Dark Mode, iPad multitasking, and keyboard and trackpad support. Use Shortcuts or Siri to check library changes through x-callback-url automation. One purchase includes both iPhone and iPad. No subscriptions or in-app purchases. YOUR LIBRARY, YOUR PRIVACY Your library history is stored on your device. There are no adverts or usage analytics. Spatial Audio matching is optional and requires an internet connection. If you enable it, Apple Music track identifiers are sent to my server to check for matches. These identifiers are used only to process the request and are not stored.

Marvis Pro's advantage is update cadence (every 9 days vs every 3 months) and review sentiment (85% vs 65%). On ads and device support there is nothing between them.
