CallSign Check vs Phone Hardware & Diagnostics

CallSign Check is the fast way to look up any amateur radio callsign. Type a call, get the full picture — no account, no clutter, no waiting. US LOOKUPS (FCC) • Full license dossier from the FCC ULS database: name, license class, address, grant and expiration dates, FRN, and previous callsign • Live prefix suggestions as you type — start with "W1A" and watch the matches roll in • Station location on a map, with grid square • Distance and beam heading from your location to the station — point your antenna with confidence (your position never leaves your device) • Phonetic readout of every callsign, ready for the air DX LOOKUPS (WORLDWIDE) • Flip to VFO B and look up operators worldwide: name, country, DXCC entity, CQ and ITU zones, grid square, and QSL manager VANITY CALLSIGN HUNTING • Check whether a callsign is currently assigned before you file a vanity application • Search the FCC database by name, city, state, ZIP, or license class with Advanced Search BAND CONDITIONS AT A GLANCE • Live HF propagation strip on the home screen: solar flux, A and K indices, and band-by-band day/night conditions BUILT FOR OPERATORS • Favorites and lookup history, stored on your device • Share any station dossier with one tap • Miles or kilometers, your choice • A focused, dark, radio-room interface that does one thing well CallSign Check is not a logger or a contest tool — it's the lookup app you reach for when a call comes back to you and you want to know who's on the other end. 73!

"Know what your iPhone or iPad can do, verify key hardware functions, and understand performance with guided diagnostics designed for real-world use. Choose a fast Quick Check, run a Full Diagnostic, or open individual tests. Check display colors and touch coverage, speakers and microphones, cameras and torch, motion and environmental sensors, storage, charging state, network and Bluetooth connectivity, biometrics, and supported features such as NFC, UWB, LiDAR and Apple Pencil. Performance tools can measure CPU, GPU, memory, storage throughput, frame pacing and thermal-state changes using repeatable workloads. Every test explains what it checks, how it works, and what the result can actually prove. Automatic measurements are kept separate from user confirmations. Permission limits, unsupported hardware and inconclusive conditions are shown clearly instead of being treated as failures. Use focused inspection modes when buying or selling a used device or after a repair. Save diagnostic history, compare selected results over time, retry items that need attention, and create clear reports that can be shared when needed. Privacy is built into the testing flow. Camera, microphone and sensor access is requested only when a relevant test needs it. Test captures are not kept permanently unless you choose to save or share them. The available test list adapts to the hardware your device actually supports, so you are not asked to run features that are not present. Some advanced checks may require compatible hardware, an accessory, an NFC tag or a second Apple device. Important: this is an independent diagnostic utility, not an Apple service tool. iOS does not provide third-party apps with every low-level metric. Exact CPU/GPU sensor temperatures, real-time processor clock speeds, official Battery Health percentage and cycle count are not presented as measured values when the public APIs do not provide them."
