iFunctionGenerator turns your iPhone, iPad, or iPod Touch into an audio function generator. You can have up to 20 generators, each operating at a different frequency. Each generator can be one of the following types: • Sine Wave • Triangle Wave • Sawtooth Wave • Square Wave • Pink Noise • White Noise The volume of the left and right channels can be independently controlled, and may be set using either a slider for ease, or direct entry of the volume, for maximum precision. The relative phase of each channel may also be set. Frequencies from 1 to 20,000 Hz may be entered. The phase can vary between -360 to 360 degrees. The volume may be between 0 and 100 percent. The mute button makes it easy to quickly silence the audio generators. You can take snapshots of the generator settings. This lets you build a library of settings, and quickly load the desired settings.

Verdict

The call

The clearest difference is price: MultiSens at Free against iFunctionGenerator's $2.99. MultiSens also leads on rating (5.0 vs 4.4) and update cadence (monthly vs every 12 months). iFunctionGenerator's advantage is ratings volume (9 vs 1) and iOS requirement (6.0 vs 11.0). On ads, in-app purchases and device support there is nothing between them.
