DayCity - The world's "now" as living art on your home screen.

Most weather apps just show numbers. DayCity brings the world's "now" to your home screen as living art. Our widgets feature stunning isometric cityscapes that update hourly with local weather. Powered by AI, the scenery evolves daily—you'll never see the exact same city twice. With "Time Travel", scroll through the past 24 hours to relive a Parisian sunset or Tokyo morning. Save breathtaking moments as snapshots! Discover a new world every day.
