Sensor Viewer vs RF Link

Visualise the data from 3 of your phone's sensors And adjust the sensitivity of the sensors to match the sounds, vibrations or magnetic fields you're measuring For sounds: See a sound wave for all sounds picked up by the microphone For Vibrations: See 3 line graphs showing the movements of the phone, 1 line per dimension (up/down, left/right, forwards/backwards) For Magnetic Fields: See a graph of the magnetic field your phone can detect, even if that's just your speakers or the batteries in some of your other devices Supports Light Mode / Dark Mode Supports Dynamic Text Sizing Supports English, French, Spanish, German Optional one-time in-app purchase available to remove ads permanently. Purchases can be restored on supported devices using the same Apple ID or Optional auto-renewing subscription available to remove ads. Subscription automatically renews unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings.

RF Link brings professional-grade RF path, radio line-of-sight, Fresnel zone and path-loss analysis to your iPhone, using the Longley-Rice (ITM) irregular terrain propagation model. Built for telecom engineers, RF planners, broadcasters and wireless network designers, it delivers accurate point-to-point link evaluation for frequencies from 20 MHz to 20 GHz. Whether you are planning microwave links, Wi-Fi backhaul, LOS radio links or long-distance wireless communication, RF Link predicts terrain impact, path loss and link feasibility in seconds. KEY FEATURES ITM Longley-Rice model (20 MHz - 20 GHz) - Industry-standard Irregular Terrain Model - Accurate diffraction, scatter and line-of-sight predictions - Multiple reliability and confidence combinations Radio line-of-sight analysis - Geometric LOS check - Earth-curvature LOS with adjustable k-factor - 60% first Fresnel zone clearance - Minimum clearance at obstruction points - Suggested tower height increase Terrain elevation profiling - High-resolution elevation sampling - Plots showing terrain, curvature, LOS and Fresnel zones - Zoomable charts you can share Coverage heatmap - Signal-strength coverage area around a transmitter - Rendered over real terrain on the map Path loss and link budget - Path-loss prediction - EIRP, RSSI, SNR and link margin - Clear pass, warning and fail indicators Clean, fast interface - Map-based transmitter and receiver selection - PDF report export - Plot image sharing and saving IDEAL FOR - Wireless network planners - Microwave and LOS link engineers - UAV and drone communication designers - Amateur radio operators - Students learning RF and propagation models RF LINK PRO Every install includes a number of free calculations. RF Link Pro removes the limit, and comes two ways: - Monthly subscription: unlimited path profiles and coverage maps, billed monthly, renewing automatically. - Lifetime: a one-time purchase, no subscription. Payment is charged to your Apple Account at confirmation of purchase.
