Altitude barometer

Barometer, altimeter, compass and GPS four-in-one. No ads, no in-app purchases, no internet connection. Using a variety of built-in sensors, 8 color matching themes, and a change curve display function, the location can be displayed on the map. Designed specifically for fishing enthusiasts, it can be transformed into an ordinary barometer after hiding the fishing prompt function, so it is also suitable for other types of outdoor activities, including mountaineering, skiing, and outbound travelers, including scenic mountain climbing, plateau travel, and high-rise sightseeing. wait. 【Functional Features】■ Equipped with barometer and compass functions, it can display air pressure, altitude, longitude and latitude. ■ It has a suitable fishing prompt function and can calculate the suitable fishing pressure based on altitude. The prompt function can be turned off. ■ With map display function; supports 3D Touch function. ■ It has the function of displaying graphs of pressure changes. ■ The measurement range is from 300 hPa to 1100 hPa, basically covering plains and most plateau areas. ■ 0.01mbar resolution, more sensitive to air pressure changes. ■ The air pressure unit supports hPa (mbar) and inches of mercury inHg. ■ The main interface has 8 color schemes, which can be switched by sliding left or right. ■ Supports personalized customization of displayed information and provides multiple setting options. [Operation Method]■ Start measuring air pressure and obtain position and orientation information upon startup. ■ Click the "Start/End" button below to start or stop measurement and positioning at will. ■ Click (or press) the Location button to display the location on the map. ■ When this measurement ends, the current air pressure value will be automatically saved. The history can also be cleared. ■ Click (or press) the "Graph" button to display the pressure change curve. ■ Slide your finger on the air pressure change curve to display the detailed information of each air pressure information. ■ Click (or press) the "Help" button to set the longitude and latitude display format, air pressure unit and other options. ■ When in the "Measure" state, the compass will automatically rotate with the arrow pointing to the north (magnetic north or true north can be selected). ■ Slide your finger left or right on the main interface to switch color schemes. [Power-saving and traffic-saving design]■ Whether the positioning and air pressure measurement functions are turned on or not is entirely up to the user, just turn them on when in use. ■ When entering the background, the positioning function is automatically turned off and the background refresh function is turned off. ■ Whether it is the positioning function or the map display function, the software has been optimized to the greatest extent possible to minimize power consumption and network traffic.
