New version 1.1 → 1.2

• AltLog now speaks ten more languages: German, Spanish, French, Japanese, Korean, Portuguese (Brazil), Russian, Thai, Vietnamese and Simplified Chinese. • Metres or feet: the height unit follows your region, and you can change it in Settings. • Open a session in History to see its altitude profile again. • The screen stays awake while a session is running, so auto-lock no longer cuts a climb short. • The direction threshold and the haptic tap on a change of direction in Settings now do what they say. • New in Settings: rate AltLog and see related apps.

About

AltLog is a one-tap elevation logger. It reads the barometric pressure sensor built into your iPhone and turns it into a live tally of height climbed, height descended and stair-equivalents — in metres or feet. There is no GPS. None. AltLog never asks for your location, and the pressure sensor uses far less power than GPS. WHEN IT WORKS • Inside parking garages, multi-story buildings and stairwells where GPS is useless. • On stairs, hills and short climbs where you want the number, not a map. • In elevators — see how much height the ride really covered. • Anywhere there is air. (Sealed pressurised vehicles excepted — physics, not us.) HOW TO USE 1. Tap Start before a staircase, a hill or a walk. 2. Keep AltLog open: it measures while it is on screen, and it keeps the screen awake during a session. 3. Tap Stop when you're done. The session lands in History with its altitude profile. WHAT YOU GET • Live cumulative ascent, in metres or feet, and in stair-equivalents (1 stair = 0.20 m). • Cumulative descent, counted separately from the climb. • An altitude profile chart for each session, kept in History. • The height unit follows your region, or your own choice in Settings. FREE AND PRO Recording sessions is free, and your three most recent sessions are always there. AltLog Pro, a one-time in-app purchase, unlocks your full session history. PRIVATE BY DESIGN No account. No cloud. No ads, no tracking. Pressure samples are processed on-device, and your sessions are stored only on your iPhone. Deleting the app removes everything.
