Trail Sense

Trail Sense is a dedicated tool for outdoor use on Android phones, operating entirely offline without uploading any data, relying solely on the phone's GPS, barometer, magnetometer, gyroscope, and other hardware sensors. It can be fully utilized in remote mountains and wilderness areas without signal or network, making it suitable for hiking, climbing, camping, outdoor survival, and geocaching scenarios. It includes offline maps, which are named using the pinyin of the provinces. You can download all provinces together or download them as needed; just download the province you need. The method to import offline maps is as follows: open the app, tap the 【Tools】 button in the bottom right corner, scroll down to find 【Offline Maps】 and click to enter, then tap the blue + button in the bottom right corner. A pop-up icon will appear; select the second icon (the file one), and then choose the offline map file (go to the folder where the map file is downloaded and select it). After selecting, a naming window will pop up; click OK to finish. **Core Features:** **1.
