PCalc vs WiFi RoomPlan

PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator. It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations. Includes an Apple Watch app, so you can calculate on your wrist!

Map Wi‑Fi dead zones while you scan your space with Apple RoomPlan. WiFi RoomPlan turns a LiDAR-equipped iPhone Pro / Pro Max or iPad into a room scanner and network survey tool. Walk slowly through your home or office; the app builds a 3D room model and pins live network performance samples to your path—so you can see where the signal drops. Key Features: Apple RoomPlan scanning — Capture walls, openings, and furniture with the LiDAR scanner (iPhone 12 Pro / Pro Max and later Pro / Pro Max models; iPad Pro 2020+ and other LiDAR iPads). Wi‑Fi or cellular test mode — Switch between Wi‑Fi and 4G/cellular probes before you scan; each saved survey records the network name and mode. Live metrics HUD — Link score, router/DNS latency, internet latency, throughput estimate, and sample count while you walk. 2D floor plan heat map — Color-coded points (strong → dead) on a top-down plan; pinch, rotate, and pan the map. 3D model with balloons — Open saved scans to inspect the USDZ room mesh with signal markers along your path. Walkthrough playback — Play a camera path from start to finish; choose 3D or 3D + 2D split view with a synced walker on the floor plan. Export to Photos — Save 3D-only or 3D+2D side-by-side walkthrough videos to your photo library; share USDZ models. Privacy first — Room models and samples are stored on your device. Network probes measure performance only; we do not sell your data. Requirements: iPhone Pro / Pro Max or iPad with LiDAR Scanner (RoomPlan) iOS / iPadOS 17 or later Camera access for room scanning Location (When In Use) to read Wi‑Fi SSID when available Photos (Add Only) to save exported walkthrough videos Perfect for finding dead zones at home, tuning mesh routers, and comparing Wi‑Fi vs cellular coverage room by room.
