Great Tool!
Very great tool for tuning and in my opinion it's only missing a few handy things if one uses this tool for meditation or chakra-opening. In this case there should be 1 tuning wheel extra at the end to make it possible to create frequencies with a 1/100th accuracy. For instance the so called Earth-day frequency is exactly 194.18Hz while the finest tuning of this app is limited at 194.1Hz or 194.2Hz. The ear of course wouldn't hear the difference but in vibration there certainly is, especially when divide or multiply the frequency. Another nice feature would be an option to divide, multiply or scale the current frequency. Until then, this tool is the greatest I've seen so far!
