VHF / UHF Radio Field Planner

Thank you for using VHF/UHF and for giving your station planning the kind of attention it deserves. This update focuses on making the app cleaner, more practical, and easier to trust during real radio work. The goal is simple: fewer confusing screens, clearer records, better calculator inputs, stronger backup handling, and a Pro experience that explains its value without getting in your way. Cleaner app structure: * Reworked so the main destinations are easier to understand. * Added Station Milestones Settings improvements: * Added a clearer appearance preference with System, Light, and Dark choices. * System appearance now clearly follows your iPhone setting. * Updated App Status so it shows useful local record counts, storage status, backup status, update status, and Pro access. Calculator improvements: * RF line of sight inputs include units and support feet or meters. * RF power inputs now use labels and support watts, dBm, and dBW. * Converter lets you choose the input distance unit and focuses output on practical distance units. * Map Distance supports stored locations without triggering navigation warnings. * Calculator inputs now show clearer units where radio operators expect them. Records and backup cleanup: * Helpful checklist templates remain available. * Import validation explains what needs review before replacing local data. * Backup export remains free. VHF/UHF should feel like a radio planning tool, not a settings console. The app is still local*first, still built for practical VHF and UHF work, and still careful about reminding you to verify legal limits, terrain, equipment ratings, RF safety, and local coordination before transmitting or installing equipment.
