PeakCard is a live altimeter and a clear, full-screen summit sign for hiking, climbing, cycling, and travel. Open the app to see current altitude, location, and vertical accuracy in large type. Hold it up in portrait or landscape so a companion can capture you, the scenery, and the height in one photo. Eight built-in themes range from restrained contours and editorial color bands to clouds, trails, star maps, and layered snow mountains. Each theme adapts to iPhone, iPad, portrait, landscape, light appearance, and dark appearance. Decorative motion respects Reduce Motion and the in-app Dynamic Background setting. Useful controls: • GPS altitude and, on supported devices, the absolute altimeter • Manual meters or feet selection • Address-first, coordinates-first, or hidden location • Multiple address and coordinate formats • Valid vertical accuracy • Keep-screen-awake mode and a display lock Home Screen widgets: Add a small or medium PeakCard widget on iPhone or iPad. Each widget can choose its own theme and refresh altitude when WidgetKit grants an update opportunity. Actual refresh timing is controlled by iOS, so widgets do not promise continuous real-time updates. The free version includes unlimited use of a free theme and the complete altitude data experience. A one-time Unlock All Features purchase permanently unlocks all premium themes, their widgets, and future standard built-in themes. Privacy: Altitude, location, and address data are processed on device. No account is required, and location data is not uploaded.
