QRV (I am ready) is your essential ham radio multitool built for DX success and maximum operating efficiency. Stop juggling apps! QRV aggregates critical tools and reliable, fast-updated data into one single, clean platform. Available on iPhone, iPad, Mac, and Apple Watch. --- QRV is designed to get you the information you need quickly, whether you are in the field or at the shack: - Real-time Band Conditions: Access live propagation data from HamQSL to find the optimal frequency. - Universal Search: Look up a callsign, jump to a DXCC entity by name or prefix, or check your band plan for a frequency — all from one place. - Cross-Device Sync: Favorites, frequency memories, settings and alerts follow you — through iCloud, or with a free sign-in wherever you use QRV. - My Frequencies: Save important frequencies (weekly nets, calling channels, and more) with name, mode, and notes. - Comprehensive Call Sign Lookup: Search easily via QRZ and/or HamQTH. - QRZ QSO Confirmation: See at a glance which bands you've worked a station on, across every QRZ logbook you own. - DXpedition Calendar: Track active and upcoming DXpeditions worldwide — see local spots and worldwide on-air activity side by side. - POTA Spots: Browse live Parks on the Air activations with band, mode, and search filters. - Band Plans: Detailed frequency allocations for 22 countries across North America, Europe, Africa, and Oceania — available in English and a native language - Glanceable data on the Apple Watch. See spots, the top bands, POTA stats, and solar conditions on your wrist. - Built-in Calculators: Antenna lengths (dipole, Slim Jim, J-Pole), coax & feedline loss, battery runtime, and power calculations. - Beginner-Friendly Reference: Q-codes, CW (Morse code) with audio, Prosigns, RST, APRS commands, Maidenhead grids, and more. - Full VoiceOver support and colorblind-friendly design. Note: Full QRZ data requires an XML and/or API subscription. Note: The Apple Watch app requires watchOS 11 (Apple Watch Series 6 or later, SE 2nd generation, or Ultra). Earlier watches aren't supported. --- PREMIUM FEATURES - Live Spots: Get reliable, high-speed spot delivery from PSK Reporter. - Rover Mode: Temporarily view live spots and band activity for any grid square without moving — widgets, Apple Watch, and alerts all follow the grid you choose, then revert automatically. - Lightning Proximity Alerts: Get warned when lightning is detected near your station so you can disconnect in time — fixed location or GPS-following, with an adjustable radius. - Customized Notifications: Set alerts for bands, DXCCs, DXpeditions, and individual callsigns with configurable thresholds. - Home Screen Widgets: Check band conditions at a glance without opening the app. - DXpedition Alerts: Get notified when your tracked DXpeditions are spotted. - Callsign Alerts: Get notified when a specific callsign is spotted from your location. - Logbook-Aware Alerts: DXCC and Callsign alerts auto-manage based on your QSO/QSL history from Wavelog or QRZ Logbook. Why Premium? These features require robust infrastructure: - I run dedicated servers to aggregate PSK Reporter data, process notifications, serve band conditions, and provide DXpedition info. - This delivers faster, more reliable data than direct API polling while being a good steward to upstream services like N1DQ's PSK Reporter. - Premium subscriptions help cover ongoing server and infrastructure costs. Your subscription is shared between all versions of the app. --- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

CCTV TIME DIFFERENCE Determine, document and report CCTV clock discrepancies quickly and accurately. CCTV Time Difference is a professional tool for investigators, security professionals, CCTV technicians and others who need to establish the exact difference between a CCTV system timestamp and the correct reference time. Create a case, capture the displayed CCTV timestamp using the iPhone camera, let OCR read the time, and compare it with the calibrated reference time. The app instantly calculates the exact offset and clearly shows whether the CCTV system clock is ahead of or behind the correct time. Your examinations can be saved as individual cases, allowing you to return to previous work and keep multiple CCTV time examinations organized. KEY FEATURES • Case Management – Create new cases or return to previously saved examinations • Automatic OCR – Capture a still reference image of the timestamp displayed on a CCTV monitor and let the app read the date and time automatically • Calibrated Reference Time – Compare the CCTV timestamp against an accurate reference time • Instant Time Difference – Automatically calculate the exact difference between the CCTV clock and the reference time • Ahead or Behind – Immediately see whether the CCTV system clock is running fast or slow • Manual Time Entry – Enter or correct the displayed CCTV time manually whenever required • Multiple Examinations per Case – Keep relevant time examinations together within the same case • Professional PDF Reports – Generate detailed reports documenting the examination and calculated time difference • Save or Share Reports – Keep the completed PDF report or send it using the standard iOS sharing options • Dark & Light Mode – Choose the appearance that works best for you WHY CCTV TIME DIFFERENCE MATTERS CCTV clocks are not always synchronized with the correct time. A recording system may be seconds, minutes or even hours out of sync. When CCTV footage is compared with witness statements, access-control records, communications, transactions or other time-based information, knowing the actual clock difference can be essential. CCTV Time Difference provides a structured way to establish, document and report that difference. From a single timestamp check to multiple examinations within a case, the app keeps the process simple, consistent and easy to document. 14-DAY FREE TRIAL Try CCTV Time Difference with full access for 14 days. After the trial period, continue using the app with a single one-time purchase that unlocks the full app permanently. No subscription. No recurring payments. Once purchased, your full access does not expire. CAMERA AND OCR USE The iPhone camera is used only to capture a still reference image of displayed information, such as the date and time shown on a CCTV monitor or system interface. The still image is used as input for OCR recognition and as documentation of the time information examined by the user. The camera feature is not used to record surveillance footage or other CCTV video. CCTV Time Difference does not connect to CCTV cameras, DVRs or NVRs to retrieve recordings. The app does not download, copy, stream, extract or distribute CCTV video or audio. Images captured by the app are used as reference and documentation material within the user's CCTV time examination workflow and are not captured for publication, entertainment or redistribution of surveillance material. CCTV Time Difference is a focused calculation and documentation tool for CCTV timestamp examination. It is not a CCTV recording, surveillance monitoring, video acquisition or media distribution application.

Verdict
The clearest difference is update cadence: CCTV Time Difference at every 2 days against QRV's weekly. QRV's advantage is device support (4 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
