About Sun Tracker AR
By Zuzana Eskinasi
Sun Tracker AR combines an AR Sun path with 2D and 3D maps, solar reference data, eclipse tools, and a day-and-night map.
It also includes an object-and-target simulator for testing how a placed box or tree affects a target spot over time.
Why look beyond Sun Tracker AR?
- You need shadows from the buildings and terrain around a real location.
- You want to scout a remote site at ground level using Street View.
- You want to test multiple planned structures within the surrounding scene.
- You need Moon, Milky Way, celestial-alignment, or location-note tools.
- You use Android or want configurable widgets paired with repeating event reminders.
How we evaluated the alternatives
We compared what each app can do rather than the length of its feature list. These criteria keep the ranking tied to the decision a user is trying to make.
Can it answer the real location question?
A useful alternative should do more than report sunrise and sunset. We looked at whether each app can move to another place and date, show the direction and elevation of the Sun, and give enough spatial context to decide whether the expected light will actually be usable.
How does it represent shadows?
A shadow ratio, a line from one object, and a scene-wide map of building or terrain shadows answer different questions. The rankings distinguish those approaches instead of treating every feature containing the word “shadow” as equivalent.
Can the plan continue from home to the location?
Remote maps, Street View, saved locations, live AR, planned structures, and alerts each support a different stage of planning. We favored coherent workflows while still crediting specialist apps for reference tables, celestial alignments, or device reach.
What is the app genuinely best at?
Every option receives a specific best-for label based on the job it handles most clearly. The overall ranking also considers how complete and coherent its workflow is for the needs covered by the roundup.
Are the claims current and checkable?
We verify each feature before including it and distinguish confirmed capabilities from assumptions. Platform availability and product details are checked when the roundup is reviewed.

The 5 best alternatives in detail
#1 · Best for overall sunlight planning
SunCast
SunCast is the best overall Sun Tracker AR alternative for understanding sunlight and shade around a real property, landscape, garden, street, trail, or proposed site change.
SunCast is a sunlight-planning app for decisions that depend on what the light will do at a real place. Its live AR view shows the Sun path on location, while the 3D map renders shadows from mapped buildings and terrain for a selected place, date, and time.
The same workflow includes Street View sun-path scouting, hourly cloud cover, detailed solar times, native Solar Alarms, building-level Solar Info, and Construction Mode for placing adjustable planned structures. That combination makes SunCast especially useful for property checks, gardens, daylight photography, hiking, solar scouting, and early site planning.
Sun Tracker AR’s placed box or tree is useful for a controlled target test. SunCast instead begins with the mapped scene: buildings and terrain cast shadows across the 3D map, and Construction Mode can add multiple adjustable planned objects alongside them.
Live AR remains available on site, while Street View supports remote ground-level scouting. Native Solar Alarms carry the plan through to the moment the user needs to act.
Strengths
- Scene-wide building and terrain shadows on a 3D map
- Street View sun-path scouting for remote locations
- Multiple adjustable planned structures in Construction Mode
- Building-level Solar Info for direct-light timing
- Hourly cloud cover alongside the solar path
- Native Solar Alarms for time-sensitive light windows
Tradeoffs to check
- Focused on iPhone and iPad rather than Android or a broad multi-device ecosystem
- Does not include Moon, Milky Way, or star-trail planning
- 3D maps, Street View, and current weather context require network data
Choose SunCast when: you want the most complete workflow for understanding sunlight and shade around a real place.
#2 · Best for outdoor map layers
Sun Quest
Compared with Sun Tracker AR, Sun Quest adds outdoor and winter-sports maps, building-level solar information, and UV and weather context.
Strengths
- Outdoor and winter-sports map options
- Building-level solar information
- Ten-day weather and UV context
Tradeoffs to check
- No user-placed planned structures
- No native solar-event wake-up alarms
- No Moon or Milky Way planning
- Does not include Sun Tracker AR’s detailed eclipse and day-and-night reference tools
- Its 3D maps, Street View, and current weather features depend on network data
Choose Sun Quest when: specialized outdoor maps matter more than detailed solar reference tools.

#3 · Best for Moon and Milky Way planning
Sun Surveyor
Sun Surveyor suits photographers planning Moon, Milky Way, or star-trail compositions. Position Search helps find where and when a celestial alignment will occur.
Strengths
- Sun, Moon, Milky Way, and star-trail planning
- Position Search and Photo Opportunities for alignment discovery
- Android availability
Tradeoffs to check
- Uses calculated shadow lines and indicators rather than scene-wide mapped 3D building and terrain shadows
- No cloud forecast
- No planned-structure simulation
- No day-and-night world map
- No eclipse map
Choose Sun Surveyor when: Moon or Milky Way alignment matters more than scene-wide shadows.

#4 · Best for Android widgets and reminders
Sun Position
Sun Position combines Sun and Moon paths with configurable widgets and repeating reminders. It is a practical alternative for Android users who cannot install Sun Tracker AR.
Strengths
- Android availability with configurable home-screen widgets
- Repeating event reminders
- Sun and Moon paths in both AR and map views
Tradeoffs to check
- No scene-wide 3D building and terrain shadows
- No Street View or cloud forecast
- No elevation-aware 3D scene for inspecting a whole location
- No eclipse map or day-and-night world map
Choose Sun Position when: Android support, home-screen widgets, and repeating reminders are the priority.

#5 · Best for scouting with location notes
Lumos
Lumos combines Sun-and-Moon Street View with saved locations and notes. It is a practical option when you want to record observations while scouting places remotely.
Strengths
- Saved locations with notes
- Sun-and-Moon paths in Google Street View
- Year calendar, detailed ephemeris, and event notifications
Tradeoffs to check
- The shadow module calculates a selected object rather than rendering scene-wide mapped shadows
- Available only on iPhone and iPad
- Map and Street View do not work offline
- No cloud forecast
- Does not include Sun Tracker AR’s eclipse map or day-and-night world map
Choose Lumos when: you want to keep notes alongside remote Sun-and-Moon scouting.
Which alternative should you choose?
| Your situation | Choose | Why |
|---|---|---|
| Overall sunlight planning | SunCast | It connects mapped shadows, Street View, planned structures, Solar Info, live AR, and alarms. |
| Outdoor map layers | Sun Quest | It adds outdoor and winter-sports maps, building-level solar information, and UV context. |
| Moon and Milky Way planning | Sun Surveyor | It combines Position Search with Moon, Milky Way, and star-trail planning. |
| Android widgets and reminders | Sun Position | It provides Sun and Moon paths, configurable widgets, and repeating event reminders on Android. |
| Scouting with location notes | Lumos | Its Street View and saved notes support repeat location research. |
Bottom line
Sun Tracker AR remains a good choice for solar tables, eclipses, and its day-and-night map. SunCast is the best overall alternative when you want one workflow for mapped shadows, remote scouting, planned structures, live AR, and timely alerts. The other options are better fits when the priority is a narrower specialty: outdoor map layers, Moon and Milky Way planning, Android widgets and reminders, or location notes.
