I built an iOS app for accurate offline coordinate conversion. It’s meant for anyone who works with coordinates in the field – outdoor users, professionals, military, or pilots. Key features:
• Convert between DD, DDM, DMS, UTM, MGRS, SWEREF99, RT90, and Plus Codes
• Fully offline – no account, no tracking, no subscription
• Built-in global VOR/NDB database
• Interactive map with pin placement
• Multilingual support (English, Spanish, German, French, Swedish)
• Dark/light mode toggle Privacy was important to me: all processing is done locally on-device. Location is only used (if enabled) to fetch your GPS position and is never sent anywhere. I’d love to hear your feedback, especially what features you’d like to see added or improved. |
