VERT — the altimeter that never loses your day

VERT tells you exactly how high you are, from the valley floor to a 3,000 m summit, and quietly records the shape of your day while you hike or ski. It reads altitude straight from your iPhone's barometer, so it keeps working with no signal, no account, and nothing in the cloud. Open it on the first lift of the season or deep in a forest with zero bars — it still just works.

Where other trackers let you down — an app that closed and lost the whole day, a summit with no reception and no saved route — VERT is built so your day is safe, even offline.

Key features

• A big, honest altitude reading from the barometer, shown with Apple's real ± accuracy — never a made-up number.

• Records every hike and ski day: your route on the map, the elevation profile, vertical gain and loss, runs, and time.

• Real mountain photo backdrops that shift with your altitude, or a clean hand-drawn illustrated mode in a tap.

• A compass when you want one, plus an altitude trend and a barometric pressure trend that hints when the weather is turning.

• Your whole season as a poster worth printing, and share cards from any day — your own memories, not stock imagery.

• Everything stays on your phone, and any day exports as a GPX file whenever you like.

How it works
Start a hike or a ski day and drop the phone in your pocket — VERT keeps recording with the screen off and pauses itself when you stop to rest. Back down in the valley, open the day for the map, the elevation profile and honest stats: steps and distance count only what you moved under your own power, so a bus or a chairlift never inflates them. Pin the altitude to a known height or to the map's terrain when you want it exact, and optionally save a finished day to Apple Health as a workout.

What's new in this version
Altitude calibration by hand or from the map, a live pressure trend, optional Apple Health workout saving, automatic pausing on breaks, and sharper coordinates.

What's free, and what's Pro
The app is fully usable for free — the live altimeter, recording, both hiking and skiing, the day summary, history, photos and GPX export. VERT Pro is a one-time purchase, never a subscription, and adds an ad-free experience everywhere, a per-segment breakdown of every day, the season widget and Lock Screen, and the printable season poster. Any ads only ever appear on the day summary and the logbook — never on the altimeter or while you're recording.

Requirements
iPhone on iOS 17 or later. Offline altitude uses the barometer built into every recent iPhone; GPS adds your position and the map when there's a signal. No account and no internet required.
