MeterWorks Teslameter vs NODs™

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.

Night Vision Camera for iPhone NODs is a live night vision camera for iPhone that helps you see more clearly after dark. Using on-device AI, NODs enhances available light in real time to create a brighter, clearer view of your surroundings. Use NODs as a night camera for nighttime walks, paths, doorways, campsites, parking areas, yards, trails, dark rooms, entrances, and other low-light places. NODs is not infrared or thermal imaging and cannot see in complete darkness. It works with the light already available around you and never records video. SEE MORE AT NIGHT Open NODs, point your iPhone camera at the scene, and look around using the enhanced live view. Use NODs to: • See more clearly after dark • Make out paths, sidewalks, trails, and doorways • Check what is ahead before you move • Find objects in dark or low-light places • Look around campsites and outdoor spaces • Check yards, entrances, and parking areas • Navigate nighttime walks and unfamiliar places • Get a clearer view of your surroundings NIGHT VISION FOR EVERYDAY LIFE NODs turns your iPhone camera into a practical nighttime viewing tool. Walking home after dark? Get a clearer look at the sidewalk or path ahead. Arriving somewhere at night? Find an entrance, doorway, or landmark. Camping or outdoors? See more of your campsite, trail, gear, and nearby surroundings when ambient light is available. Looking for something in a dark room, yard, or parking area? NODs enhances available light to make details easier to see. HOW NODS NIGHT VISION WORKS NODs uses on-device AI to enhance the visible light your iPhone camera can already capture. Unlike infrared night vision or thermal cameras, NODs does not require or provide specialized night vision hardware. NODs works best when some ambient light is available, such as moonlight, streetlights, building lights, outdoor lighting, or nearby lamps. NODs cannot see in total darkness, detect heat, see through walls, or provide thermal imaging. NIGHT VISION FOR CAMPING & OUTDOORS Use NODs as a low-light camera for camping, nighttime walks, travel, trails, outdoor spaces, and late-night arrivals. Get a clearer live view of campsites, walking paths, equipment, parking areas, entrances, landmarks, and nearby surroundings. NODs is not a replacement for a flashlight or dedicated night vision equipment, but it can help you see more of a low-light scene using the iPhone already in your pocket. FREQUENTLY ASKED QUESTIONS Is NODs a night vision camera? NODs is a low-light night vision camera app that uses on-device AI to enhance available light through your iPhone camera. Can I use my iPhone as a night vision camera? NODs gives your iPhone an enhanced live nighttime view using the visible light available in the scene. Can NODs see in complete darkness? No. Some available light is required. Does NODs use infrared? No. NODs does not use infrared imaging or infrared illumination. Is NODs a thermal camera? No. NODs does not detect heat or provide thermal imaging. Does NODs record video? No. NODs provides a live camera view and does not record video. When should I use NODs? Use NODs when you want a clearer view after dark—while walking, camping, traveling, finding an entrance, checking a path, looking for something, or viewing nearby surroundings. USE NODS RESPONSIBLY NODs is a nighttime visibility aid, not a replacement for safe lighting, a flashlight, dedicated safety equipment, or paying attention to your surroundings. Do not use NODs while driving or whenever using your phone could be unsafe. PRIVACY NODs uses your iPhone camera for its live night vision view. It does not record video.
