## What is SunOnTrack?

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.

RECOMMENDED BY PROFESSIONALS:

„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. Pay once, get full access forever. 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.


NOTE:

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.

### 5/5 — Eine tolle App

*2026-06-06*

Sehr hilfreich und gut übersichtlich

**Developer response:** Hallo und vielen Dank für deine positive Rezension!
Viel Erfolg mit SunOnTrack und sonnige Grüße ☀️

### 5/5 — Wow!

*2026-05-01*

Vor dieser App wäre ich mit Winkelmesser und Meterstab auf mein Dach geklettert, und hätte die Verschattung mit Sonnenstand, Jahreszeit und Mathematik berechnet…so spare ich mir viel Zeit und Mühe. Einziger Nachteil: die Zeitleiste überdeckt teilweise den Winkelkreis. Alles in allem tolles Tool!

**Developer response:** Hallo! Herzlichen Dank für deine tolle Rückmeldung und deine überaus positive Bewertung! Eventuell verdeckt die Zeitleiste unter einer bestimmten Bildschirmauflösung einen kleinen Teil – wir kümmern uns darum. Wir würden uns sehr freuen, wenn du SunOnTrack so positiv weiterempfiehlst. Viel Freude damit und viele Sonnenstunden dir! Thomas ☀️

### 5/5 — Excellent and useful

*2026-02-13*

I use this for assessing building lots, planning where to put A/C units and choosing where to stay, even pick a parking spot. It’s a great app that simply works and is useful. Thank you.

**Developer response:** Hi maxllama, thank you very much for your great review! Wishing you all the best and lots of sun (or perfect shade) with SunOnTrack! Thomas ☀️

### 1/5 — Shadows

*2026-02-07*

The shadows are static and don’t change with time of day . Don’t waste time paying for the app

**Developer response:** Hi! This review seems to be based on a misunderstanding. The static shadows visible in the background come from the satellite map imagery itself. Any objects placed on the map within SunOnTrack generate real, dynamic shadows that change precisely with time of day and throughout the year based on the entered height(s) and location. You can also add multiple objects for complex shadow simulations.
We reached out by email to clarify this and assist, but haven’t received a response yet. If you experienced different behavior, please contact us with details so we can help resolve it. If this clarifies the issue, we’d appreciate an updated review.

Sunny regards ☀️

### 1/5 — Não possui projeção de sombra

*2025-04-18*

O aplicativo não tem opção pra teste, comprei imaginando que o app trazia a projeção de sombras dos prédios, mas não tem essa opção, apenas simulação bem ruim manual.

**Developer response:** Hola! Gracias por sus comentarios. SunOnTrack ofrece muchas funciones profesionales sobre el sol y simula sombras de objetos definidos por el usuario en el mapa, en línea con lo prometido. Es justo evaluar la aplicación basándose en la calidad y no en expectativas divergentes. Si es necesario, puedes solicitar un reembolso. ¡Saludos al sol! 🌞

### 4/5 — Schattensimulation?

*2025-02-14*

Die Höhe der Schattenobjekte kann recht gut eingestellt werden. Die Platzierung der Elemente müsste für meine Zwecke aber präziser, zum Beispiel über Abstände von markierten Punkten. 
Insgesamt aber gute App.

**Developer response:** Schönen guten Tag! Sehr schön zu lesen, dass nun mit der Schatten-Simulation alles gut geklappt hat! Vielen Dank für Ihr Feedback! Falls Sie weitere Fragen oder Anregungen haben, melden Sie sich gerne. Viel Erfolg mit SunOnTrack und sonnige Grüße! ☀️

### 5/5 — Schattenwurf von Gebäuden simulieren

*2024-12-11*

Wir konnten mit der App den Schattenwurf eines neu entstehendes Gebäudes auf unser Haus simulieren.
Das hat sehr gut funktioniert und war mit der App einfach anzulegen.
Auch hatten wir bei einer Anfrage an den Support innerhalb ein paar Stunden eine Antwort erhalten mit sogar noch zusätzlichen Hinweisen/Hilfestellungen.
Sehr zu empfehlen!

**Developer response:** Hallo! Vielen lieben Dank für Ihre sehr positive Rezension, sehr schön! Viel Erfolg für Ihren Anwendungsfall mit SunOnTrack und melden Sie sich gerne, wenn weitere Fragen aufkommen. Sonnige Grüße ☀️

### 1/5 — Carte obsolète

*2024-10-25*

Très déçu que la carte qui serve de support soit obsolète. J'ai coupé des arbres en 2021 afin de mettre en place une installation solaire. Les arbres figurent encore sur cette vieille carte Google. L'application m'est donc inutile

**Developer response:** Bonjour,

Merci beaucoup d'avoir partagé votre avis ! SunOnTrack utilise les données cartographiques en ligne d'Apple Maps, qui sont mises à jour régulièrement. Cependant, la fréquence et l'étendue de ces mises à jour dépendent entièrement d'Apple, et nous n'avons malheureusement pas le contrôle sur ce processus. Dans certaines régions, cela peut effectivement prendre plus de temps.

Nous comprenons votre frustration, mais nous pensons que la note attribuée ne reflète pas entièrement la qualité de l'application ni les fonctionnalités qu'elle propose. Nous vous encourageons à les essayer pour tirer le meilleur parti de SunOnTrack.

Nous vous remercions pour votre compréhension et vous souhaitons une journée ensoleillée pleine de succès !
Thomas

### 5/5 — Toll aber

*2024-09-30*

Wirklich gute App ist den Preis wert ! 

Was mir fehlt sind die Wind Daten! Würde das mit Einflüssen wüsste ich von vielen das großes Interesse bestünde.

**Developer response:** Hallo! Vielen Dank für deine überaus positive Rezension! Dieser Punkt kommt auf die Liste, auch wenn derzeit Sonne und Schatten die fokussierte Expertise von SunOnTrack darstellen. Weitere Updates folgen! Danke und sonnige Grüße.

### 4/5 — AR not working

*2024-07-01*

AR 3D error required sensor failed on iPhone 13 Pro. All permissions have been granted and AR 3D works on other apps. Camera engages and then immediately fails. 
Found that share location on your camera must be enabled, I never enable camera locations. 
You can always disable it again after using the app.

**Developer response:** Hi! This issue is due to your iPhone‘s compass calibration being disabled (for all apps) and can easily be solved - you may just contact our friendly support (me) before writing a bad review. Please go to System Settings (Settings app) -> Privacy & Security -> Location Services -> (usually at the very bottom:) System Services -> Compass Calibration. This must be enabled (it is by default). Please let me know and consider correcting your review. Thanks a sunny regards.
