Solar & Lunar Compass is an offline compass app that lets you check the movement and position of the sun and moon based on your GPS location and a selected date. You can also set a location manually.

It displays sunrise, sunset, moonrise, and moonset times, along with azimuth, elevation, moon age, and lunar illumination.

No ads. No network communication.

【Main Features】

• Display sunrise, sunset, moonrise, and moonset times
• Show the directions in which the sun and moon rise and set
• Display the current azimuth and elevation of the sun and moon
• View moon age, lunar illumination, and the estimated number of days until the next new or full moon
• Select past or future dates to explore the paths of the sun and moon
• HORIZON View for viewing their paths from the side
• COMPASS View for viewing their directions from above
• Compass display using orientation sensors on supported devices
• Manual compass alignment on devices without a magnetic sensor
• GPS altitude correction for rise and set times and HORIZON View
• GPS Edit Mode for manually entering latitude, longitude, and a time zone
• Select location presets and save custom locations for later use
• CAMP Mode to reduce animation and screen brightness

Use the app to plan photography locations and times, check sunlight and moon directions, and prepare for travel, camping, and other outdoor activities.

【Calculation and Sensor Accuracy】

Displayed positions and times are calculated estimates. GPS altitude correction accounts for the horizon appearing lower at higher elevations. Mountains, buildings, and other local obstacles are not included in the calculations, so actual visibility times and directions may differ from the displayed predictions.

The numerical elevation readout shows geometric elevation. HORIZON View uses a corrected elevation to align the graphical horizon crossings with the calculated rise and set times.

Compass accuracy depends on your device’s sensors and the surrounding magnetic environment. Metal objects, electronic devices, and vehicles may affect the displayed direction. On devices without suitable sensors, align the compass manually.

【Location and Privacy】

Location permission is required when using GPS to obtain your current position. You can also use manually entered coordinates.

All calculations are performed on your device. The app displays no ads and makes no network connections.

Designed for smartphones. Operation on tablets is not guaranteed.
