Read full descriptionHide full description
This is not an altimeter that pretends to be exact. GPS, barometer, and your calibration anchor are shown separately. If the uncertainty is large, you will not get a fake integer. Altitude Calibrator fuses GPS orthometric height with a calibrated barometer and shows confidence plus an error range. Built for hiking, climbs, and checking a reading against a trail sign or pass marker. Free โข Live altitude with GPS / pressure / anchor side by side โข Trip high, low, and cumulative ascent โข Altitude cards to save or share Membership unlocks tools (3-day free trial, then weekly auto-renewal) Compass, speed, pressure, sunrise/sunset, level, flashlight, and coordinates. Altitude, trips, and cards stay free. Manage or cancel in Settings โบ Apple ID โบ Subscriptions. Unless auto-renew is turned off at least 24 hours before the period ends, the weekly charge continues after the trial. Readings include uncertainty and are not a surveying product.
