I am using a USB Mio plugged into my iPhone. It is simple and effective. ### 4/5 — Very useful for testing. *2024-12-11, version 1.4* It is good, but i have a request. can it get dark mode? ### 5/5 — Great free tool *2024-08-13* Super useful for debugging midi devices. The only thing I could really want is if column headings stayed at the top of the page when live data was scrolling. But I can memorize 3 columns. Thanks for the great app! ### 5/5 — Does what it should! *2024-04-24* This works great for verifying the messages coming from my various Bluetooth controllers. Simple and easy to set up, and the data is presented in a format that a relatively unskilled user like me can understand. Excellent! ### 4/5 — Affichage message sysex limité en caractères *2023-03-17, version 1.4* L’affichage d’un message sysex est limité à 9 caractères et donc impossible de voir un message supérieur à cette limitation Dommage mais application utile quand même !!! ### 5/5 — Works great for me *2022-11-19* Has been a very helpful app. Thank you for making it. ### 5/5 — Extremely useful tool for hunting down MIDI problems *2021-12-14* Great app. ### 5/5 — Better than several other equivalent tools...and it is free !!! *2020-12-03* This app works wonderfully and has even more functionalities than a few other tools that pretend to do the similar MIDI monitoring but you have to buy them. I would only suggest an additional filter to be able to sort out events by CC number. **Developer response:** Version 1.6 now has the ability to filter by CC number ### 5/5 — Works better that other midi monitors *2019-10-26, version 1.4* Works better that other midi monitors ### 5/5 — Solved setup difficulties *2019-03-20, version 1.3* I have found this app to be extremely useful when setting up an instrument. Instead of hoping for the best it clearly shows MIDI information being received confirming if the instrument is working or not. ## Frequently asked questions about MIDI Scope ### What is MIDI Scope?
