It provides you with a real-time glanceable view of all MIDI activity on your computer. ShowMIDI is designed to be always on, using the spacebar or play/pause button you can pause the flow and focus on a data snapshot with the latest state of any MIDI entity. ShowMIDI can be ran as a standalone application that automatically detects all your MIDI devices, or as an AUv3 plugin in your DAW or host to visualize MIDI data in your sessions. ShowMIDI visualizes: * MIDI ports * channels * program change * note on/off * channel pressure * polyphonic pressure * continuous control change * pitchbend * RPN and NRPN * MPE configuration and channel modes ShowMIDI supports: * themes * standalone operation * AUv3 operation

Verdict
The clearest difference is update cadence: Composody at weekly against ShowMIDI's every 2 months. ShowMIDI's advantage is iOS requirement (12.0 vs 16.1). On price, ads, in-app purchases and device support there is nothing between them.
