Vibration Measurement is device sensor log tool that enables you to monitor the vibration from your iOS Devices. You are able to preview the vibration data with graphs. Perfect for the casual user with user friendly UI. Features: ∙ Show device acceleration data in X, Y and Z direction. • Show device acceleration data by color. [X - Red, Y - Green, Z - Blue] • Can easily determine vibration direction. • Preview live acceleration data in a graph. • Lightweight app with a small size, optimized for everyday use. Display Data: • Device acceleration in [G] gravity • Maximum Amplitude in [mm] millimetre for each X,Y and Z axis • Average [G] data • Maximum [G] data • Maximum Amplitude in [mm] millimetre • Device Acceleration Data retrieve every 0.1 second [10Hz] • Time and Date show as a reference Formula: v = at Device velocity [v] = device acceleration [a] * time [t] s = vt Displacement/distance [s] = Device velocity [v] * time [t] 1 g-units = 9.8066 Metres per second squared Quick Start Guide: 1. Place your device on top of any surface. 2. Tap reset to start measuring the vibration. 3. You can enable screen recording to record the vibration process. Usage: • Measure the vibration of machine, motor or anything else. • Measure vibration in car/truck while driving/idling. • Record the vibration while riding/driving on difference road condition. • And many more depend on your imagination. Tips: • Place your device with its screen facing up for stability during vibration measurement. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.

Muzz is a professional-grade real-time spectrum analyzer built for audio technicians, acoustic engineers, musicians, and sound enthusiasts. Whether you're diagnosing room acoustics, analyzing live microphone input, inspecting harmonics and feedback, or studying the frequency characteristics of any audio signal — Muzz gives you the tools to see exactly what you're hearing. 21 spectrum graph types, from standard linear analyzers to advanced harmonic alignment and octave-aligned displays, give you flexibility no single visualization tool can match. NEW IN 1.0.8 — Live frequency axis: Hz markers (100–8kHz) displayed permanently along the bottom of every visualization — Long press anywhere on the visualization to pin the exact frequency at that point for 2 seconds — Continuous background audio: Muzz now keeps analyzing when your screen locks or you switch apps — critical for live monitoring sessions — CarPlay compatible: enabling the microphone no longer interrupts audio playing through your car system — Frequency labels adapt automatically to dark and light mode Core Features — Load any audio file and visualize its full spectrum in real time — Live analysis mode via device microphone — ideal for room acoustics, stage monitoring, and field work — Persistent Hz frequency axis on every visualization — Long press to inspect exact frequencies at any point on the spectrum — Peak enhancer: isolates spectral lines (harmonics, fundamentals) and suppresses percussive noise — Toggle visualization variants to explore alternative display modes — Gain and treble controls to calibrate the display to your signal level — Dark and light mode with automatic label color adaptation — Runs continuously in the background — no interruptions during live sessions 21 Spectrum Graph Types Bars Extended Bars Short Line Spectrum Music Spectrum Linear OAS Overlapped Octaves Octave Aligned Spectrum Elliptical OAS Spiral OAS Harmonic Alignment TriOct Spectrum Overlapped Harmonics Harmonograph Cymbal Rainbow Spectrum Waterfall Rainbow OAS Rainbow Ellipse Spinning Ellipse Out of the Rabbit Hole Down the Rabbit Hole For in-depth theory on each spectrum type, tap the info icon to access the full Visualizations Guide.
