NEW name, even sunnier! Sunnytrack is now >> SunOnTrack!

SunOnTrack (formerly SUNNYTRACK) 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.

What’s New

Excellent App

I bought the Sunnytrack App for checking Sun exposure on a proposed new garden building. I also wanted an estimate of shadow positions. The shadow tool is simple to use and It’s been brilliant for both! It basically models any shape by joining points and specifying a height, so you can’t model sloping roofs etc but using common sense (e.g. a simple wall at roof ridge height) it clearly shows equivalent shadow position with any date and time. I will also be using it for photography (golden hour/ blue hour and sunrise/sunset positions). The map and satellite views are well designed and intuitive when you try them out for different purposes. The Sun position using the AI tool was a bit off on my iPhone but after I calibrated the iPhone compass, it was spot on (so not the apps fault! ) The AI view is something I will use a lot I think! All in all a great app at a reasonable price. Very happy with it.

Developer Response ,

Hi. Oh thanks a lot for your wonderful feedback! It‘s so nice to read the app supports you that perfect in various use cases. You may also simulate e.g. sloping roofs by placing a separate shadow object for each of the edges or points with different heights. Enjoy tracking the sun, planning its position and simulating shadows. All the best and thanks again! Sunny regards, Thomas ☀️

Tree shadows

In the short time I have been using the app it seems to be 5 stars. Plotting trees is easy detailing heights is easy. Being able to save locations is wonderful, and then edit them again is so good. I do have a wish list though.

Wish list
Being able to send each saved location to my email inbox with an aerial map showing shadows, date and time with an attached list of trees their reference number and height and canopy diameter would be awesome. I hope the developer can do this.

Been worth the price it cost to buy.

Simple to use yet sophisticated results

Sun track is great for solar panels but the shading part of the app is seriously brilliant!
Shading for solar panels is the hardest thing to identify unless you spend a lot of money. This does it in minutes for a few pounds!
Indispensable if you are planning solar panels.

Hi toppydj! Thats so nice to read, thanks a lot for your very positive review. Enjoy using the app. All the best, great success and lots of solar energy to you! ☀️
