Alti-watcher 6.08

Alti-Watcher is an application specifically designed to monitor the elevation gained during mountain hiking. It effectively utilizes both GPS and barometric data to provide accurate altitude readings.

The initial location and altitude are obtained through the GPS module, transitioning to barometric measurements after approximately 30 seconds. This ensures a continuous recording of elevation changes even when the phone’s screen is off. When the sleep prevention mode is activated, the GPS is turned off while maintaining the barometer's functionality.

The compass feature includes a dial indicating the sun’s position at sunrise and sunset, represented by a yellow dot for sunrise and a red dot for sunset, accompanied by a level marker signified by two concentric circles.

Data presentation is offered on daily, monthly, and cumulative bases. The monthly graph illustrates performance across all days of the current and previous months, highlighting the best daily performance in red. Additionally, a second graph tracks results across current and prior years, with a capacity to display data for up to ten years. The total result for each month or year is distinctly marked in red.

Upon completion of a route recording, users can access the profile charts tab to view the current route profile. These charts can be organized by date, elevation, or trip duration in descending order, with options to name or delete specific route profile charts. Users can also export these charts as JPG files saved in the Alti-Watcher/charts directory on their devices for sharing purposes.

The application features an audio cue that plays every 20 meters of climbing or descending by default, which can be adjusted or disabled according to user preference. This function enhances usability, especially when carrying the phone in a backpack during hikes.

Additionally, users have the option to record altitude gain and trail profiles with the flexibility to pause recordings during rest periods. Automatic pausing occurs after eight hours of inactivity, though this duration can be customized between four and forty-eight hours.

Implementing dim screen and sleep prevention modes significantly improves altitude reading accuracy while only slightly increasing energy consumption. A high refresh rate mode captures profile charts at one-second intervals; however, these results are not saved in this mode.

To ensure precise barometric calibration, users can select an appropriate temperature range, visually represented by a thermometer in the altimeter view. Importantly, the application does not collect or transmit any user data; database backups are securely stored on the device and can be restored if necessary.

For optimal performance of the barometer feature, it is essential to enable Fitness Tracking in the device settings:

• Open the 'Settings' app.
• Navigate to 'Privacy & Security'.
• Select 'Motion & Fitness'.
• Activate the 'Fitness Tracking' toggle.
