Bygone - Yesterday's Weather
Forecasts based on history
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Bygone helps you understand today’s weather by showing how it’s changed since yesterday.
Instead of overwhelming forecasts or raw numbers, Bygone focuses on what’s different — making weather easier to grasp at a glance. See how temperature has risen or fallen, whether rainfall has increased, how wind speed has shifted, and how conditions like cloud coverage, UV levels, and humidity have evolved since the previous day.
Whether you’re deciding what to wear, planning a walk, or just curious about how the atmosphere is changing around you, Bygone turns weather into a story of progression rather than a static snapshot.
Key features:
Compare today’s weather directly against yesterday’s conditions
Track changes in temperature, rainfall, wind speed, cloud coverage, UV index, and humidity
Clean, minimal design that highlights meaningful differences
Beautiful light and dark modes that adapt to your preference and environment
Bygone is designed to be simple, informative, and calm — no clutter, no noise, just the changes that matter. Weather doesn’t happen in isolation, and with Bygone, you’ll always know how today compares to what came before.
Discover the weather through time. Discover it with Bygone.
