About

True Random Numbers

Features
Read full description

Most random number generators calculate the numbers with pseudo random number generators. But this app leverages your device's motion sensors, swipes, or camera input, to generate authentically random numbers and shuffles. It also doesn't have a modulo bias, a common problem with random number generators.

SunLight

SunLight helps you understand natural light at a glance. Open the app to see where the sun is, how high it is, and how the light will change through the day. A calm visual compass shows the sun direction around you, while the timeline highlights sunrise, sunset, solar noon, golden hour, blue hour, twilight, and night. Switch to the room scene to preview how sunlight enters a simple indoor space. Set a window direction or follow the phone heading to understand whether a room, balcony, desk, or plant corner gets direct light at a given time. Use SunLight when you need to plan with real sunlight: - Check which direction the sun is coming from right now. - Plan photos around golden hour and blue hour. - Preview sunlight in a room, window, balcony, desk, or plant spot. - Scrub through the day to see how the light changes. - Compare sunlight for another date or location with SunLight Pro. - Use local sun calculations after location is available. SunLight is useful for renters, home buyers, plant lovers, photographers, outdoor planning, and anyone who wants a clearer sense of daylight. SunLight Pro unlocks: - Any-date sunlight planning. - Room sunlight simulation. - Map location selection. - Live compass heading readout. Privacy: your location is used on device to calculate the sun's position. SunLight does not upload your location. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
