Point your iPhone in any direction and see a live direction line on the map, complete with distance markers. Identify mountains, check line of sight, and explore the world around you — all offline.
DirectionExplorer uses your iPhone's GPS and compass to draw a live direction line on a real map. Tap anything on the horizon and get detailed information instantly.
A red line follows your compass heading in real time on a standard, satellite, or hybrid map. Distance tick marks (auto or fixed: 1, 5, 10, 20, 50 km/mi) tell you exactly how far you're looking at a glance.
An offline database of peaks worldwide is built into the app. Filter by altitude range, search by name, and place selected summits directly on the map. No internet connection required.
Tap a peak or pin and the app analyses the terrain between you and the target. It tells you whether the view is clear or lists the intermediate peaks that block it — with their elevation and distance.
Select any pin or mountain to see its distance, bearing, elevation, and coordinates in both decimal and DMS format — all calculated in real time from your current position.
Drop pins by tapping the map or searching for an address. Assign colour-coded flags, add notes, and manage your collection in a dedicated list. Pins are saved locally across sessions.
Lock the direction line to freeze a specific heading, then share your position, bearing, and target details via any app — Messages, Mail, WhatsApp, and more.
Automatically calculates how far you can see to the geometric horizon based on your GPS altitude. Useful for planning long-distance observations or radio path checks.
Set the origin point by tapping any position on the map instead of using GPS. Plan viewpoints from home, check a route before you leave, or compute paths between any two places on Earth.
Switch between metric and imperial units, choose map style, enable or disable the compass overlay, lock the origin, and set your search radius — all settings persist across sessions.
The entire mountain database ships inside the app. You can search, filter, and display peaks on the map even in the most remote areas — no Wi-Fi or cellular required.
Whether you're identifying a distant summit, planning a photo shoot, or checking a radio path, DirectionExplorer gives you the information you need right on the map.
