‣ What is Sunlitt?

Sunlitt is an app that tracks the sun’s position and movements anywhere and at any time, all in a delightful and human-centered interface.

With Sunlitt, sun tracking is made quick, easy, and fun.

Along with the Sun Path, Sunlitt provides precise timings for several key solar events, such as golden and blue hours, sunrise and sunset, first and last light, twilights, and much more.

Sun data in Sunlitt is computed locally and most features are accessible offline, respecting the user’s privacy and ensuring they are always aware of the sun's journey in the sky, even in the most remote locations.

Monolitt Mode

‣ Monolitt Mode

Sunlitt’s Monolitt mode offers a simple and intuitive way to visualize the sun’s path. This mode presents a 3D rounded cube model on the ground (the Monolitt), with the sun’s track moving around it. As the sun moves, the shadows cast by the Monolitt change accordingly.

Using the devices' built-in gyroscope, you can turn your phone to view these shadows from different angles, making it feel like you’re directly interacting with the sunlight.

On the left side of the screen, there’s a date slider that covers every day of the year, allowing you to select any date you want. On the right side, a time slider lets you pick any hour and minute of the day.

By combining these two sliders, you can see the sun’s position and the resulting shadows at any given moment.

Explore, AR, Solar Events

‣ Explore Mode

Sunlitt’s Explore mode provides access to a detailed sun path overlaid on a map. As you move or search for different locations, the sun path updates accordingly, even in areas where the sun doesn’t rise or set.

By default, Explore mode opens with a Shadow Map, where you can observe real-time shadows of buildings worldwide, in addition to the sun’s path. Sunlitt also offers satellite and terrain map styles, along with the ability to switch between 2D and 3D perspectives.

Similar to Monolitt mode, you can use the date and time sliders to view the sun’s trajectory at any time, for any chosen location.

‣ AR Mode

Sunlitt is compatible with Augmented Reality (AR). When you set the location to your current position, Sunlitt allows you to switch to AR mode. Your camera will capture the real-world scene, with Sunlitt’s interface overlaid on your surroundings through your device screen.

In AR mode, you can view not only the sun’s path but also the equinox and solstice paths, which delineate the portion of the sky the sun travels throughout the year at that location. Additionally, you can place the Monolitt in your scene, displaying real-time shadow patterns for a more immersive and informative experience.

‣ Solar Events

Sunlitt also provides extensive information about solar events. By dragging or tapping the bottom bar with the address, Sunlitt displays a comprehensive view with all the relevant details about the sun for that specific day, time, and location.

In this view, you can access, in order: weather information, sun azimuth and sun altitude, first light, morning blue hour, sunrise, morning golden hour, solar noon, evening golden hour, sunset, evening blue hour, last light, solar midnight, day and night lengths, as well as morning and evening twilights (including civil, nautical, and astronomical timeframes). It also includes details about solstices and equinoxes, coordinates, and current elevation.

With the date and time pickers, you can easily and precisely select the desired date and time, without needing to go back to the sliders in Monolitt mode.
