## Description

Track live altitude and pressure, record elevation sessions, and use built-in mountain references — no GPS, account, analytics, or developer cloud.

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.
