About this app

FreqFinder calculates the intermodulation products of user entered transmitter channels and then suggests options of channels that will be compatible with user transmitters already in use.

Recommended for use with 12-24 transmitter systems depending on the processing power of your device and the spread of your transmitters.

US Customers: TVDB in-app purchase now available. Accesses the FCC database for local TV broadcast towers and estimates the field strength at your location for better channel selection.

Please add the options for using IEMs. I work in UK outside broadcast, mostly sport, mostly football. This app has bee very useful. Being able to block out a frequency range would be useful too, but there's ways to work around this currently. Being to use the camera to add mic data in by reading the label would be a dream function too.

I love the app. There is a bug I came across. If you try and create a custom transmitter, the app crashes on my Pixel 2 phone. Other than that, it helped me coordinate 10 wireless body packs, 8 wireless hand held mics and 6 in ear monitor transmitters (that's 24 transmitters all on different frequencies).. We were having all kinds of issues and this app helped clean it all up. Since I couldn't find a profile for Galaxy Audio 1400 in ear I was going to do a custom transmitter but the app would crash when trying to save it so I just found another profile that matched close to the 1400 in ear transmitter and used that and it worked. I did buy the tv plugin because I was pretty sure we were also getting tv station interference also. It went out and found my local tv stations and avoided them in the suggested frequencies to use. Very nice. If you could add the Galaxy Audio AS-1400 In Ear Monitor to the app, that would be the best. Thanks .

This app gives me the same frequencies for my lectrosonics and sennheiser g3's no matter where I am in the SF Bay Area. They never change EVER. And they are never clean frequencies either. Am I missing a step here? Samsung s10, all current software.
