Yesterday’s weather

Most weather apps don’t show you yesterday’s weather. Who cares, right? But it’s useful information if you want to know whether today will be warmer or colder than yesterday. Yesterday is a free iPhone app that shows a chart of the hour-by-hour temperatures for yesterday and today. If it’s late in the day, you can see how tomorrow’s weather will differ from today’s. It also gives you a simple one-sentence summary, like “Today will be noticeably hotter and sunnier” or “Daytime high noticeably warmer and rain unlikely.” It was created by Matt Webb, who publishes Interconnected, one of my favorite newsletters. It’s a great example of vibe coding. — MF
