MHz โ wireless frequency coordination that travels with you. Whether you're mixing monitors on a world tour or setting up two handhelds in a school hall, MHz helps you find clean, legal frequencies for wireless microphones and in-ear monitors โ anywhere, even offline. Find clean spectrum, anywhere Location-aware lookups show you which TV channels and white spaces are actually free where you're standing. In the United States, United Kingdom, Canada, and Australia, the full transmitter database is bundled into the app โ no signal required. In Denmark, Sweden, Norway, and Finland, MHz queries the national regulators' own live frequency services for the most current picture, and regulation summaries for 40+ more countries are always available offline. Talk to your gear. Link MHz directly to Shure and Sennheiser hardware on your network. See live RF and battery status, push frequencies to your receivers, or pull their settings into your show file โ per channel or a whole group at once. Collaborate with your crew. Share frequency groups with other MHz users via iCloud. Everyone sees the same plan, updates arrive with push notifications, and nobody's working from an outdated spreadsheet. Import and export freely. Bring in coordination files from Wireless Workbench and Soundbase, merge them into your groups, and export frequency ranges back out. MHz plays nicely with the tools you already use. Actually understand RF. The built-in Intermod Tool teaches you intermodulation from first principles โ interactive chapters plus a playground where you drag transmitters around a virtual stage and watch the spectrum react.

Verdict
The clearest difference is price: 2CA expense at Free against MHz's $2.99. 2CA expense also leads on iOS requirement (12.0 vs 17.0). MHz's advantage is chart position (#108 vs unranked). On ads, in-app purchases and device support there is nothing between them.
