Sun Pathway: Sunlight Tracker

See the sun before you sign the lease.

Sun Pathway uses augmented reality to show you exactly where the sun travels across the sky — from any location, on any date. Just point your phone and watch the sun's arc appear live on your camera view.

--- PERFECT FOR APARTMENT HUNTERS ---

Visiting a new apartment? Point your phone at each window and instantly see:
• How many hours of direct sunlight this window gets
• Whether it's morning sun or afternoon sun
• How sunlight changes from summer to winter

Generate a PDF Apartment Sunlight Report with photos and data for every window — share it with your partner, roommate, or agent.

--- PERFECT FOR PLANT PARENTS ---

Stop guessing which window gets "bright indirect light." Sun Pathway shows the exact sun hours for any spot in your home, every season. South-facing windows get 12+ hours. North-facing? Maybe 4. Now you know.

--- PERFECT FOR REAL ESTATE AGENTS ---

Stand out from every other listing. Add branded sunlight snapshots to your presentations. Show clients exactly how much sun each room gets — backed by data, not guesswork.

--- HOW IT WORKS ---

Sun Pathway uses the NOAA Solar Position Algorithm — the same standard used by meteorologists and engineers. The sun's position is calculated from your GPS coordinates, date, and time, then projected onto your camera view using your device's compass and gyroscope.

Note: Sun path calculations assume clear line of sight to the sky. Actual sunlight may vary due to buildings, trees, and weather conditions.

--- PRIVACY ---

No accounts. No tracking. No data leaves your device. Location is used only for solar calculations and is never transmitted anywhere. See our full privacy policy for details.

Requires iOS 16+. iPhone 8 or later.
