Live altitude at a glance

Fused GPS and barometer data show altitude, pressure, relative elevation change, speed and oxygen level in real time, plus trends from the last 5 minutes.

One-tap track recording

Start, pause, save — three steps. Recording continues in the background or with the screen locked, with an elevation profile, map and 3D view in the details.

3D track replay and sharing

Turn the route you walked into a 3D track: rotate, zoom and pan freely, colored by altitude, with the ground switchable between grid, map and satellite imagery plus projection. Then create a shareable card to save or send to friends.

Platform note: the 3D ground offers grid / map / satellite imagery on iOS, and grid / map on HarmonyOS.

All-day footprints

Low-power significant-location-change wakeups log the places you visit in the background, no manual check-in needed. Every point carries altitude, pressure, temperature, speed and location accuracy, with photos and notes.

Platform note: on iOS the system wakes the app with low-power location changes, so footprints keep being logged after you leave the app; on HarmonyOS the app must keep running in the background.

Record comparison

Put any two records side by side: differences in altitude, distance and elapsed time, settled in one look. Same route — how much did this time differ from the last? Now you know.

Import, export, backup

Import GPX and KML tracks; export tracks as GPX and footprints as CSV. Back everything up to the cloud with one tap — a private iCloud container on iOS, HUAWEI Cloud on HarmonyOS — and restore it on a new device.

Platform note: the HarmonyOS version can also export a backup as a zip file, or import one back.

10 languages, metric or imperial

Switch between Simplified and Traditional Chinese, English, Japanese, Korean, French, German, Spanish, Italian and Russian, and between metric and imperial units.

iOS and HarmonyOS, the same AltiView

Both platforms share every core capability; the few that differ do so because of what the system allows — listed honestly below

Where they differ

Cloud backup: iOS writes to your own private iCloud container; HarmonyOS writes to HUAWEI Cloud, and can also export a backup as a zip file or import one back.
All-day footprints: iOS is woken by the system's low-power location changes, so it keeps logging after you leave the app; HarmonyOS relies on a system long-running task and needs the app running in the background.
3D track ground: grid, map and satellite imagery on iOS; grid and map on HarmonyOS.
Weather and temperature: the home weather card and per-point temperature are iOS only (HarmonyOS does not expose a weather service to third-party apps).
Dark mode: HarmonyOS follows the system light / dark theme; iOS is light only.
