Naxos Music Library (NML) offers over 2.73 million tracks of fine classical music recordings from more than a thousand labels with their latest releases. What sets NML apart from other streaming platforms comes down to metadata. Each piece of music comes with a rich set of information, from composers’ biographies to programme notes, instrumentation to publisher’s details, all authored by qualified musicologists. Individual subscribers and authorised users of institution subscribers can create their own playlists on top of having access to playlists created by their teachers and professors for their assignments. NML is more than just a huge classical music audio library available for streaming. The Resources section inside the library offers many valuable add-ons and study tools available through accessing the web version.

MusicToolKit

MusicToolKit is a simple, capable toolkit for practicing music. Five tools in one app: metronome, tuner, tuning fork, recorder and keyboard. Open it and start right away. METRONOME · Accurate clicks: no drift or lag, however long it runs · Accents, compound meters (6/8 etc.) and bar-by-bar meter changes (4/4 + 5/4 etc.) TUNER · A steady readout: the display doesn't jump around, so you can tune calmly · Piano-roll-style scrolling graph shows how your pitch moves TUNING FORK · Pick the note on a piano-style keyboard · Reference pitch can be set anywhere from 400 to 500 Hz and is shared with the tuner and keyboard. 415, 432 and 440–444 are one tap away RECORDER · Dual level graph (peak and average): clipping warnings make distortion obvious, so setting the level is easy · Lock button prevents accidental taps while recording. Levels are shown before you start · Saves as WAV / M4A. Open recordings directly in the Files app, or export via the share sheet KEYBOARD · A simple tap-to-play keyboard · Sine, square, triangle and sawtooth waveforms Tuning is equal temperament. For just intonation and other temperaments, see "MultiTuneKeys". Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: NML at none against MusicToolKit's 1. NML also leads on ads (none vs shown) and iOS requirement (15.3 vs 18.1). MusicToolKit's advantage is update cadence (daily vs every 2 months). On price and device support there is nothing between them.
