MeterWorks Teslameter vs MeshScan

Your iPhone has a real magnetic field sensor — this app turns it into an honest instrument. No ghost detector, no ads covering the reading, no subscription: MeterWorks Teslameter measures, records, and documents magnetic fields. MEASURE • Live field strength |B| with a big readout and a smooth real-time graph • All three axes plus magnitude, 100 Hz sampling, µT or mG • Zero baseline: blank out the ambient field and hunt magnets and metal in delta mode • Compass calibration state shown honestly RECORD & ANALYZE • Recordings with key metrics: RMS, peak, peak-to-peak, crest factor • Zoom, pan, and cursor in the recording graph — stats for the visible range • Pro: FFT spectrum with peak list and AC field indicator (50 Hz mains hum, beta) YOUR DATA IS YOURS • Free: PNG export of all four channels • Pro: clean CSV export of the full raw series — spreadsheet-ready • Pro: multi-page PDF report with statistics matrix, time series, spectra, and measurement documentation FREE VS. PRO — NO SURPRISES Free is a real instrument: unlimited live measurement, three recordings of 10 seconds each, full metrics, PNG export. Pro is a single one-time purchase: unlimited recordings, FFT analysis, CSV and PDF export — all future Pro features included. No subscription, ever. WHAT THIS APP CANNOT DO — HONESTLY The magnetometer measures static and low-frequency magnetic fields up to 50 Hz (the Nyquist limit of 100 Hz sampling). Radio frequency — cellular, Wi-Fi, Bluetooth — is beyond ANY smartphone magnetometer; apps promising "radiation readings" are bluffing. This is not a wire detector either: always use a proper scanner before drilling. The in-app page "Limits of this measurement" explains exactly what works. TYPICAL USES Locate magnets and magnetic metal · compare speaker and magnet field strength · check low-frequency EMF indicatively · show Earth's field (physics class) NO SUBSCRIPTION. NO ADS. NO TRACKERS. All measurement data stays on your device. EMF put honestly in context: facts, not fear. MeterWorks is a family of honest measurement apps: Vibrometer for vibration, Sound Meter for your noise log — just as honest, just as subscription-free.

Turn your LiDAR-equipped iPhone or iPad into a portable 3D scanner. MeshScan captures real-world surfaces as live point clouds and meshes, gives you simple tools to clean up each scan, and exports files ready for your 3D workflow. CAPTURE WITH LIDAR Hold the scan control and move slowly around a surface to capture its shape. Choose a horizontal or vertical guide line for focused scanning, or switch to full-screen capture for larger areas. Live guidance, tracking status, and a point counter help you scan with confidence. CONTROL THE RESULT Choose Balanced, Detailed, or Maximum scan detail. Adjust the nearest and farthest capture distances to focus on the object or area you need. Set the point-cloud limit from 100,000 to 5,000,000 points to balance detail, performance, and file size. TRIM UNWANTED DATA Draw a lasso around unwanted points, preview the selection, and delete it. Undo your last trim if you change your mind. EXPORT FLEXIBLE FILES Share your scan in common formats: • TXT point clouds • PLY triangle meshes • Binary STL surface meshes Coordinates are exported in millimeters for straightforward use in compatible CAD, inspection, visualization, and 3D-printing workflows. RESUME TEMPORARY SCANS MeshScan automatically saves temporary scan data on your device. Choose whether to retain it for 1 hour, 24 hours, or 7 days, then return and continue working within that period. PRIVATE BY DESIGN Your scans are processed and stored on your device. MeshScan has no accounts, ads, third-party analytics, or tracking. Scan files leave the app only when you choose to export or share them. REQUIREMENTS MeshScan requires an iPhone or iPad with a LiDAR Scanner. Scan quality and performance depend on the device, surface, lighting, movement, and selected detail settings. MeshScan is free to use. Optional one-time contributions are available if you would like to support continued development.
