MIDI Scribe is a free productivity app for capturing and organizing practice takes from your MIDI-capable musical instrument. Run it while you practice, and it will automatically start new takes after every session break, with a configurable auto-take idle time, as well as support for specific MIDI commands (such as a middle or left piano pedal press) to manually start and end takes. A piano roll is provided to review and scrub individual takes. Star the takes that you want to keep indefinitely, while unstarred takes are cleaned up over time based on a configurable retention policy. All takes can be exported as MIDI files for use in other programs. MIDI Scribe is completely private. Connect your instrument, capture your takes, and keep everything securely on your device . No ads, no analytics, no snooping on your usage, and nothing ever leaves your device unless you export it. MIDI Scribe is completely free and open source for you to enjoy.

Verdict
The clearest difference is in-app purchases: MIDI Scribe at none against MIDI FX's 1. MIDI FX's advantage is update cadence (every 9 days vs every 3 weeks) and iOS requirement (14.7 vs 18.6). On price, ads and device support there is nothing between them.
