SunCast vs Sun Seeker: classic tracker or modern sunlight planner?
Sun Seeker is a long-running classic in this category. It includes AR, compass views, map tools, widgets, Apple Watch support, and solar notifications.

Quick verdict
SunCast is the better fit for modern sunlight planning with AR, 3D shadows, Street View, custom object shadows, and solar alarms. Sun Seeker is mainly relevant if you want Apple Watch support and detailed info on widgets.
This comparison uses full feature sets and intentionally avoids pricing differences.
SunCast is strongest for
- Previewing building and terrain shadows on a 3D map interactively
- Checking a remote place through street view before arriving
- Testing future building shadows with Construction Mode
Sun Seeker may still fit for
- Apple Watch users
- Users who want detailed solar event tables
Side-by-side feature comparison
| Feature | SunCast | Sun Seeker | Why it matters |
|---|---|---|---|
| AR sun path | Yes | Yes | Helps you visualize the sun's trajectory and lighting conditions before they occur. |
| Interactive map planning | 3D map with shadows | No shadow map | Lets you plan sunlight at any location before arriving. |
| Custom object shadow simulation | Custom 3D block | 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 | Yes | 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 | Alarms and notifications | No | Turns a chosen solar event into a reminder or wake-up alarm. |
Why SunCast?
It answers shadow questions directly
SunCast is built around seeing how buildings, terrain, and planned structures affect light at a real place, not just reading the sun angle.
It works before you arrive
Street View and cloud cover help you check a photo shoot, apartment viewing, garden, or site visit before standing there with AR.
It turns planning into reminders
Solar alarms and notifications make the chosen time actionable after you have found the right light window.
Detailed comparison
Shadow and site planning
SunCast. SunCast is stronger when the practical question is where shade will actually fall on a facade, patio, garden bed, campsite, or street. Solar Info also shows a mapped building's roof potential and estimated output. SunCast can place a custom 3D block to preview the shadow from a planned structure, which matters for future-building and renovation checks.
Sun Seeker. Sun Seeker is the better choice if you specifically want a classic compass workflow and detailed solar event tables more than map-based shadow planning. Sun Seeker does not include 3D shadow planning. SunCast renders building and terrain shadows across an interactive 3D map for decisions that depend on the place itself.
Remote scouting and context
SunCast. SunCast supports remote scouting when you need to understand a location before a shoot, property visit, garden check, or site walk. Hourly cloud cover adds weather context to the sun path so you can avoid planning around light that conditions are unlikely to support.
Sun Seeker. Sun Seeker works as a solar reference tool for checking sun position, event times, and compass direction. For pre-visit evaluation, SunCast is more useful because it combines the place, the sun path, and cloud context in one planning flow.
Device workflow
SunCast. SunCast concentrates on a modern iPhone and iPad workflow for AR, maps, shadows, weather, construction checks, and alarms.
Sun Seeker. Sun Seeker wins if Apple Watch support is the deciding factor and glanceable wrist information matters more than deeper iPhone and iPad planning tools. Users who primarily want widgets and detailed solar tables should choose Sun Seeker; users making location and shadow decisions get more from SunCast.
Bottom line
SunCast is the stronger choice when you want modern sunlight planning around 3D shadows, street view, weather context, construction shadows, and solar alarms.
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
Is SunCast a Sun Seeker alternative?
Yes. SunCast is a Sun Seeker alternative for users who want AR sun tracking plus deeper map, shadow, street-view, weather, and construction-planning features.
Where does Sun Seeker have an edge?
Sun Seeker has an edge for Apple Watch support, widgets, detailed solar event data, and a compass-first workflow. SunCast is stronger for 3D shadows, Street View scouting, cloud cover, construction planning, and Solar Alarms.
Which app is better for checking property sunlight?
SunCast is better suited to property sunlight checks when nearby building shadows, remote street-view scouting, or seasonal map context matter.
