SunCast vs Sun Position: sunlight planner or sun-and-moon reference?
SunCast turns the Sun's position into a clear view of the lighting at a real place: surrounding 3D shadows, planned structures, Street View, and cloud conditions. Sun Position takes a reference-first approach with Sun and Moon paths, detailed event times, widgets, reminders, Milky Way information, and an annual overview.

Quick verdict
For understanding where sunlight and shade will actually fall, SunCast is the stronger choice. Both apps cover AR sun paths, interactive maps, golden hour, twilight, and solar data, but SunCast adds scene-wide building and terrain shadows, construction simulation, Street View, hourly cloud cover, and native solar alarms in one direct workflow. Sun Position makes more sense when glanceable Sun and Moon data, configurable widgets, repeating reminders, Milky Way information, or Android support matter more.
This comparison uses full feature sets and intentionally avoids pricing differences.
SunCast is strongest for
- Seeing building and terrain shadows across a real 3D scene
- Scouting locations with Street View and hourly cloud cover
- Testing planned structures and acting on the result with native alarms
Sun Position may still fit for
- Quick Sun, Moon, golden-hour, and twilight reference
- Configurable widgets, annual charts, and repeating reminders
- Milky Way information and Android availability
Side-by-side feature comparison
| Feature | SunCast | Sun Position | Why it matters |
|---|---|---|---|
| AR sun path | Yes | Sun + Moon paths | Helps you visualize the sun's trajectory and lighting conditions before they occur. |
| Interactive map planning | 3D shadow map | Paths + compass overlay | Lets you plan sunlight at any location before arriving. |
| 3D building and terrain shadows | Yes | No | Reveals whether buildings or terrain will block the light you need. |
| Custom construction shadow simulation | Adjustable 3D structures | No | Shows how proposed buildings could change surrounding light before they appear on the map. |
| Building solar information | Yes | No | Provides building-level solar potential, panel capacity, annual sunshine, and estimated energy output. |
| Street-view remote scouting | Sun path in Street View | No | Lets you inspect a distant location's sun path without being there. |
| Cloud and weather context | Hourly cloud cover | No | Shows whether cloud cover may hide the light or shadows you planned for. |
| Solar event alarms | Native solar alarms | Repeating reminders | Turns a chosen solar event into a reminder or wake-up alarm. |
Why SunCast?
It turns a path into a lighting decision
Sun Position shows where the Sun and Moon will travel. SunCast adds the surrounding building and terrain shadows, revealing what that path means for the place itself.
It works before you arrive and before you build
Street View supports remote scouting, while Construction Mode lets you add planned structures and see how they would change nearby light.
The workflow stays visual and direct
SunCast keeps location, time, 3D shade, planned structures, cloud cover, and alarms in one coherent flow, so complex sunlight questions remain easy to explore.
Detailed comparison
From sun position to actual light
SunCast. SunCast renders building and terrain shadows together as you move through the day, making it clear which parts of a property, garden, street, campsite, or photo location will receive direct light. Construction Mode adds adjustable 3D structures to the map so you can test their shadow impact alongside the existing surroundings.
Sun Position. Sun Position plots solar and lunar paths in AR and on a map, with date and time controls and an optional compass overlay. It is effective for checking direction and timing. The path can help you reason about likely light, but the app does not render the shadows cast by nearby buildings and terrain. SunCast makes that part of the scene visible.
Planning context and follow-through
SunCast. Street View shows the Sun path from the location before you arrive, complementing the broader 3D shadow map with a ground-level perspective. Hourly cloud cover tests whether the intended light is likely to appear, while native Solar Alarms make the chosen window actionable.
Sun Position. Sun Position provides configurable home-screen widgets, detailed Sun and Moon times, golden hour, twilight phases, moon phases, hourly data, and a Pro annual overview chart. Reminders can be tied to a chosen event, location, and lead time, with daily, weekly, monthly, or custom repetition. They are useful for recurring reference, while SunCast's native alarms are built for time-critical solar events.
Scope and best fit
SunCast. SunCast is designed for decisions where local light and shade matter: photography, property viewings, gardens, hiking, architecture, solar checks, and planned construction. Solar Info adds building-level roof potential and estimated output to that workflow.
Sun Position. Sun Position is a good fit when Sun and Moon times, AR or map paths, Milky Way information, widgets, reminders, or Android availability cover the job.
Bottom line
When the job is understanding sunlight at a real location, SunCast is the stronger tool. It moves beyond showing where the Sun will be to reveal how buildings, terrain, planned structures, and cloud cover will shape the light, all within a focused and visual iPhone and iPad experience. Sun Position makes more sense when a compact Sun and Moon reference, widgets, repeating reminders, Milky Way information, or Android support is the priority.
Try SunCast
SunCast combines AR sun path, 3D shadows, street-view scouting, cloud cover, Construction Mode, and Solar Alarm for iPhone and iPad sunlight planning.
Frequently asked questions
Does Sun Position show 3D building and terrain shadows?
No. Sun Position shows the Sun and Moon paths in AR and on a map, which helps with direction and timing, but it does not render the shadows cast by the surrounding buildings and terrain. SunCast shows those shadows directly across the 3D scene.
Does Sun Position have solar alarms?
Sun Position supports event reminders with configurable lead times and repeating schedules. SunCast adds native Solar Alarms for sunrise, sunset, golden hour, blue hour, and other solar events, including time-critical wake-ups.
Which app is better for property or garden sunlight planning?
SunCast is the stronger tool when you need to see how nearby buildings, terrain, seasonal timing, or a planned structure will affect direct light and shade. Sun Position works well when the question can be answered from the Sun's direction and event times alone.
