VERT

Altimeter & ski tracker for iPhone

Your day is safe.
Even without a signal.

An altimeter that tells you the truth, and a tracker that keeps the day you walked — offline, on your own phone, with your own photographs behind the number.

Built around the things that actually go wrong

Not around a feature list. Every one of these exists because hikers and skiers keep writing the same complaints about the apps they already paid for.

It keeps the day

Nothing is lost if the app dies

The track is written to disk as you walk, not when you press stop. Force-quit it, run out of battery, drop the phone — the day is already saved.

No signal needed

The barometer works in the gorge

Altitude comes from the pressure sensor, not the network. No account, no cloud, no loading screen between you and the mountain.

Honest numbers

It shows its own uncertainty

The reading carries the ± the system actually reports. Charts never zoom into noise to look dramatic. A flat day looks flat.

Your own photos

Real mountains, not stock meadows

Backgrounds follow your altitude and the season — and they are photographs from these valleys, not a rented image library.

Hiking and skiing

Two sports, counted properly

Climbs and descents are separated. Lifts are detected and excluded, so a gondola never counts as something you climbed.

Yours to keep

No cloud, no account, export any time

Everything lives on your phone. GPX export is free, because charging to get your own season back out would be a threat, not a feature.

Nadya, the developer of VERT, at the Obersee
Obersee, 608 m — twenty minutes away, and a different country

I live under these mountains

Hi — I'm Nadya. I live in Wals-Siezenheim, just outside Salzburg and close enough to the German border that a walk can start in one country and end in the other. The Untersberg is what I see from the window, and it stands with one foot in each.

Almost none of that would have been true a few years ago: different country, different language, different work. I started walking up hills because they were simply there, outside the window, being enormous. Then skiing. Then a bike, then running shoes. Somewhere in all that rearranging I began building apps with another developer, five time zones away — less than a year ago, and nothing like what either of us used to do.

VERT is our first one for the mountains, and it started as a complaint: the altimeters I tried either rented me numbers I already owned, covered half the screen with an advert, or — the one that really stung — lost a whole day of walking because I had closed the app without pressing stop. So we built the one I wanted to carry. It saves the day continuously, works with no reception, and the backgrounds are my own photographs, each placed at the altitude it was shot.

This is version one. An Android version is on the way, and there is a lot more I want to add. If something is missing, or wrong, or would be better another way — write to me. The app is small enough that a good suggestion can be in the next release.

Every backdrop in VERT is a photograph like these, carrying the altitude its camera recorded — so the picture behind the number was taken at roughly the height you are standing at.
