## Most critical reviews (7 lowest-rated)

### 1/5 — Bluetooth Support Non Existent

*2021-04-18, version 1.0.3*

Everytime I try to connect Bluetooth midi app crashes. Using an airturn quad200, but I don’t think it’s the device because the menu isn’t even coming up. Tried closing every other app, everything. Please fix because this app is so important for what it does.

### 3/5 — Not working in AUM at the moment

*2026-04-26, version 1.0.3*

Both MIDISpy and KB-1 don’t show up in the AUV Extension list anymore for me, I can’t see them so I can’t load them in AUM. Both still work standalone

### 5/5 — Little tool but does the job, and it‘s free!

*2025-11-02, version 1.0.3*

Saved my day while debugging a nasty MIDI feedback loop in my mioXM setup. There‘s also ShowMIDI by Uwyn which offers more configuration options, but sometimes a scrolling log of all MIDI messages, Like offenes by MIDISpy, is just better.

### 5/5 — Very useful tool!

*2025-02-19, version 1.0.3*

Thank you very much! 😊

### 5/5 — Super useful!

*2022-05-19, version 1.0.3*

This is the perfect tool to diagnose erratic midi controller behavior. 
Thank you so much! Please keep up the good work, and keep this tool alive.

### 5/5 — Worth every penny!

*2021-03-31, version 1.0.3*

I need to see MPE Midi streams across a WiFi network and using my iPad Pro with MIDISpy is great. Very reliable as a stand-alone app, or as a plugin in AudioBus, AUM or as a AUv3.

Would like to see an option to save output but I can copy and paste so it’s not a big deal. 

I really hope you port all of your apps to macOS. Please always make sure that MIDI over WiFi is solid on your end, (I’m sure that’s mostly up to the OS), and support MIDI 2.0 and MIDI.org standards. I rely on this for my living. 

👍🏼👍🏼

### 5/5 — 5 stars and even a little bit more maybe...

*2020-11-27, version 1.0.3*

Kai, this is the best midi monitor I have seen on iOS (well.. iPad OS), PLEASE bring it to the iOS system too! I would love this on my phone.
