Peakline puts all of Hong Kong on your iPhone in 3D. Every hill, street and harbour is drawn from the Government's own survey data. Open your GPX and the trail lies on the hills it climbs, then turn it into a flight over Hong Kong.
THE MAP
• A clean, stylized 3D model of the whole territory: buildings, flyovers, terrain, roads and their markings
• From Lantau's peaks to Sai Kung's coast: Yau Tsim Mong comes with the app, and the detailed Hong Kong map is an optional download, recommended over Wi-Fi, and works offline once downloaded
• Sun position, sunlight, moon phases and shadows simulated for your chosen date and time
• After sunset, windows light up one by one, street lights glow along the roads, and thousands of stars and five planets come out where they really are
• Your place on the map and the way you face, used only on your iPhone
TRAILS
• Open any GPX file — from your watch, a race or a friend's WhatsApp — by sharing it to Peakline
• The elevation and climb along the way, and what's underfoot: asphalt, steps, dirt
• Add a race's checkpoints on the elevation, rename them, and take them with the GPX when you export it
PHOTOGRAPHY AND SHARING
• Long-press for a ground, rooftop or window view, then move and look around using on-screen controls
• Compose with an 8–1200 mm equivalent lens and optional Sun/Moon direction guides
• Explore the offline star map for your chosen date and time; simulated atmosphere and light pollution are illustrative, not live weather or a guarantee of what you will see
• Save and share a camera reference photo with its address, coordinates, lens, viewing angles and date/time
VIDEO
• Turn your trail into a flyover in a few taps: the camera follows you up every ridge while your distance and climb count up
• At dawn, at golden hour or under the stars
• Free trial: one HD (1080p) video and three 720p videos, with the Peakline mark

PRIVACY
No ads, no analytics, no tracking. Route processing and video creation happen on your iPhone. You choose whether to share or open a location in an external map.
PLEASE NOTE
Peakline is for planning, reliving and sharing. Map data can be out of date, so don't rely on it alone where your safety depends on it: check the weather, carry a proper map and tell someone your route.
Requires an iPhone with iOS 26 or later.
