ToneScope vs Scan3D

ToneScope helps you see and understand sound in real time. ToneScope transforms complex audio into visual representations that are easy to interpret. Whether you're exploring music, investigating environmental noise, or simply curious about the sounds around you, ToneScope makes sound easier to understand. It uses a multirate FFT approach to achieve high frequency resolution at low frequencies while remaining efficient for real-time use on iOS. Users can analyze audio in real time or record sound locally and analyze it later. All processing is performed entirely on-device. Optional audio recordings are saved locally under user control. No data is transmitted, uploaded, or collected. Designed and developed by Newton Niu.

Turn spaces and objects around you into 3D models. Capture rooms with rear LiDAR on supported devices, or capture nearby objects with the front TrueDepth camera. See geometry coverage as you scan, review your capture, then calculate the model on your device. Rotate, zoom, measure and explore models. Crop and smooth geometry, reprocess saved captures, and export OBJ, PLY, STL and USDZ files. Original capture data stays on your device. Switch between English and Simplified Chinese inside the app. Use the volume buttons to start and stop Object capture. No account, ads, subscriptions or in-app purchases. Scene capture requires LiDAR; Object capture requires TrueDepth. Glass, mirrors and low-reflectivity surfaces may be incomplete. Measurement accuracy depends on capture conditions. Photo-only reconstruction is not supported.
