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.

The app is designed to connect to a variety of wireless BLE vibration sensor and to perform different types of vibration analysis, including: - Time Waveform (Including cursors for higher peaks and difference calculation) - Spectrum Plot (Including Cursors for high peaks, cpm and sidebands) - Vibration Meter (Overall and Filtered) in Acceleration, Velocity and Displacement - Machine Acceptance Testing - Machine Motion Testing Data and Reports can be stored on the device or in the cloud for further analysis. Take out-of-route measurements (offline & online) and assign it to any point in your asset tree. The asset tree can have as many levels as you require. Note: Cloud functionality and other features will require an account with SensOS.

Verdict
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.
