GoldenCalc - Sun Tracker

Never miss the perfect light again. GoldenCalc is your smart offline timer for Blue and Golden Hour. Pay once, use forever – no subscriptions!

GoldenCalc is the uncompromising utility tool for photographers and filmmakers. Never miss the perfect light for your shots again – no matter how far off the grid you are.

No cluttered menus, no subscriptions, and no internet connection required. GoldenCalc does exactly one thing, and it does it perfectly: it calculates the key sun phases for your location with absolute precision.

The Core Features:

• 100% Offline & Worldwide: Your location data never leaves your device. The app works completely without internet, with no hidden trackers, and uses a built-in time zone database to calculate exact times worldwide – even in airplane mode.

• Live Countdown: A massive, at-a-glance timer shows you down to the second when the next phase begins.

• "You-Are-Here" Timeline: The dynamic daily timeline adapts in real time. You instantly see the current lighting conditions and what is coming up next.

• Exact Calculation: Blue Hour, Golden Hour, Sunrise, and Sunset (morning and evening).

• Smart Location Planning: Save your current GPS location for later. Planning a trip? Simply copy coordinates from Google or Apple Maps directly into the app – the format is recognized automatically.

• OLED Dark Mode: The deep black, minimalist design saves your battery and won't ruin your night vision during early morning shoots in the dark.

A Fair Deal: Pay once, use forever. No in-app purchases, no monthly fees, no ads.
