Free Frequency Generator and Oscillator

Frequency Sound Generator is an app used to produce sounds at varying frequencies. Useful for tuning audio equipment, testing hearing or simply annoying friends, the free app offers a wide range of settings to play around with and a decent selection of presets. While the free version does have a number of ads, they are generally limited and can be removed with a purchase. Overall, Frequency Sound Generator does a solid job for a few particular occasions but lacks some advanced features that a professional may require.
