SunOnTrack transforms your device into a professional tool for planning sunlight, the sun’s position, path and shadows for every place in the world (and at every time) accurately, on the map or in AR. Whether for photography, real estate, your new flat or house, gardening, photovoltaics or all outdoor activities: sunlight, sun position and shadows play a major role. See sun’s elevation, its direction, exact sun movement over day and year, objects’ shadows, shadow lengths, shadow differences between seasons, and more.


„This app is awesome! It has helped me to align the PV modules (solar panels) optimally.“ – Jürgen

„For me as a photographer SunOnTrack is an extremely practical tool. Always knowing the sun’s position in real time brings enormous relief. Planning photo shootings becomes significantly easier.“ – Aki from Akigrafie Live

„I am absolutely thrilled. I work in the real estate industry and can now use AR to check with my clients when the sun is shining on the balcony. Amazed customers guaranteed.“ – Toni K.

„It's very useful and professional. It helps me coordinate my trips.“ – Dino

PHILOSOPHY: No ads. No user tracking. SunOnTrack tracks the sun, but only the sun, not the user! For sure. This app is a professional product. It can be bought for a one-time price to get all the high quality features it offers at once, without distracting ads or the need for further in app purchases.

• CREATORS (in photography/filming) all over the world love SunOnTrack not only for its easy usage but also for the extensive functionality it offers. With it you're guaranteed to not miss a perfect scene and optimal light – during the day, Golden Hour or Blue Hour, for instance. Precise, location-dependent planning of the sun’s position and natural lighting of your subjects are extremely relevant in photography – whether capturing landscapes, objects or humans.

• You would like to know the effective AMOUNT OF SUNLIGHT a flat or house/property offers? During Winter, when days are shorter? Get a general picture in advance on Maps or impress at site visits and property tours with showing the sun’s path at the kitchen window for the whole year, live in 3D in your camera image using Augmented Reality (AR)! It’s an insiders’ tip for real estate agents, house builders or interested individuals in general.

• PHOTOVOLTAICS: SunOnTrack provides professional support in placing, adjusting and optimizing your solar modules. Where does sun rise, where does it set? See the differences between the seasons at your location.

• We love green! We love GARDENS. Plan your garden with SunOnTrack. Simulate the exact shadows of multiple objects in Shadow Simulation mode, by adding them on the map defining their heights. For example, you can see the length and impact of shadows casted by objects like houses or a trees when the sun follows its path.

• SAVE all planned scenes, sun paths, shadow simulations and your places for later use.

• As you can see in the screenshots, DAY VIEW provides precise, location-dependent information on the sun like day length, solar noon, sunrise, sunset and twilight times (like Blue Hour, Golden Hour, Astronomical Twilight, …)

• For all OUTDOOR ACTIVITIES SunOnTrack wants to be your faithful companion as a sun tracker and planner. Whether in cities, in the mountains or when touring through valleys, meadows and fields, the app develops its full potential: on Maps, live in AR or even in advance when planning.


Ideas and feedback are very welcome. Please use the provided feedback function in the app.

AR 3D functionality: SunOnTrack shows the sun’s position and path based on the orientation of your device with high precision. For identifying its orientation, your devices’ internal sensors are used. In order to achieve exact results, a calibration can be required by moving your device in a figure-eight-pattern and keeping it away of metallic objects.

Beautiful, useful, and stable

Was unsure of how good the app would be, especially after having to pay upfront. But I’ve been thoroughly impressed with how beautifully designed the app is while being pretty stable. All the tools are here are useful, whether it’s for photography and film or just know where the sun will be in that new apartment (wish I knew about this before I moved into my place). So easy to go back and forward in time, which was my biggest issue with other apps.

Impressive Technology

I found this app through a search based on a need to determine the left and right range of where the sun would set throughout the year. The app does exactly what I hoped it would and I’m very pleased. Had a question on operation and got quick and helpful response from the developer.
