Store description excerpt
AltitudeNow is a focused barometric altimeter and elevation-session logger built around one job: showing how your altitude changes as you move. LIVE ALTITUDE, WITHOUT GPS • Relative altitude from the device's built-in barometric pressure sensor • Live atmospheric pressure in hPa or inHg • A real-time altitude chart while a session is recording • Motion access is used for the barometric sensor; your recorded sessions stay on-device RECORD CLIMBS AND ELEVATION CHANGES • Start and stop named altitude sessions • Review minimum altitude, maximum altitude, elevation gain, duration, and readings • Free users can browse their 3 most recent sessions • Premium unlocks unlimited session history, detailed session charts, CSV export, and calibration BUILT FOR MOUNTAIN USE • Pick from a built-in Japanese mountain reference list when naming or calibrating a session • Save favorite mountains for faster session setup • Compare recorded elevation changes with familiar peak references • Apply a calibration offset when you know the reference altitude PRIVATE BY DESIGN • No account • No advertising or analytics SDKs • No developer-operated cloud sync • No GPS required for the core altitude recorder • Delete the app and there is no AltitudeNow cloud copy left behind PREMIUM — ONE-TIME PURCHASE • Unlimited session history • Detailed altitude charts for every saved session • CSV export • Custom calibration offset No subscription. REQUIREMENTS Requires iOS 17 or later and a supported phone with a built-in barometric pressure sensor. Devices without that sensor show a clear unsupported-device screen instead of fake readings. AltitudeNow is an informational elevation tool, not a certified navigation, aviation, emergency, or safety instrument.
