Live Spectrum Analyzer vs ModelLens

Live Spectrum Analyzer is a real-time audio visualization tool for musicians, students, teachers, sound makers, and anyone who wants to see sound clearly. Use the microphone for live input, or import an audio file from Files to inspect how frequency, amplitude, pitch, and dynamics change over time. Switch between waveform, FFT, sonogram, spectrum bars, VU meter, pitch, octave bands, peak hold, envelope, waterfall, phase, Lissajous, and XY Scope views. Each mode is designed for quick visual reading while you listen, tune, practice, demonstrate acoustics, compare sounds, or check a recording. The app also provides practical analysis readouts, including RMS, peak level, decibels, detected pitch, strongest frequency peaks, spectral centroid, zero crossing rate, dynamic range, estimated BPM, beat strength, mel bands, chroma, noise floor, and clipping status. Results are intended as helpful visual references rather than certified measurement data. Key features: • Live microphone waveform and spectrum visualization • Import audio files for playback and local visual analysis • Waveform, FFT, sonogram, bars, VU, pitch, waterfall, phase, and scope modes • Adjustable gain, time window, FFT floor, sonogram brightness, contrast, and speed • Pitch reference, tolerance, microphone gain, and noise gate settings • Record audio locally, review saved recordings, and share or delete files • Capture visualization snapshots as PNG images • Local-first workflow with no account required Subscription and purchase information: The app offers a free experience and optional Pro access. Actual prices, trials, promotions, and availability are shown in the App Store. Privacy and data information: Your microphone input, imported audio, recordings, snapshots, and analysis results stay on your device by default. The app does not require an account and does not upload your media to a server operated by us.

ModelLens is an offline 3D model viewer for iPhone and iPad. Open CAD parts, 3D-print meshes and scan point clouds the moment they arrive — no account, no upload, no network. WHY MODELLENS • 100% offline and private — no sign-in, no servers, no analytics, no tracking • Open models straight from Messages, Mail, WeChat, cloud drives or the Files app • Built for real-world sizes: smoothly loads 590k-triangle meshes and 500k-point clouds (performance varies by device) FORMATS • STL (ASCII & binary) — 3D printing meshes • STEP / STP — B-rep CAD geometry with adaptive tessellation and true topology edges (Open CASCADE kernel) • OBJ — meshes with materials • PLY — meshes and point clouds, including vertex colors FOUR RENDER MODES • Shaded — smooth solid surfaces • Wireframe — see the underlying structure • Shaded + Edges — surfaces with crisp feature edges: topological edges for CAD, triangle edges for meshes • X-Ray — translucent look-through COLORS THAT FIT YOU Seven macaron palettes (mint, matcha, peach, lemon, taro, sky, coral) drive both the interface and the 3D canvas, in light and dark mode. The default model material follows your theme. MODEL INSIGHT Live statistics: triangle and vertex counts, point counts, bounding-box dimensions, and format detection. BUILT ON OPEN SOURCE STEP support is powered by Open CASCADE (LGPL-2.1). License details are available in the app's About screen. ModelLens does not collect or transmit any data. What you open stays on your device.
