One day at a time, in real time.

Yesterly only lives on iPhone and Android. There is no web version. We wanted the app on the same surface as your alarm clock, not buried inside another browser tab.

A short onboarding asks you for two things. The year you want to revisit, and the country you were in. That is enough to sound right. The cost of bread, the weather on your street, the song on local radio.

Most people pick a year that already had a name in their head before they opened the app. The year they turned sixteen. The year they moved away. The year before everything changed.

The moment onboarding ends, your first card opens. Today's date, that year. The number one song with a thirty-second preview. One headline. The weather. Three minutes, then the card closes.

Tomorrow's card does not exist yet. It arrives tomorrow. The calendar is the product.

The free Postcard tier gives you one card a day, forever. If you want the rest of that day's world — the top five songs, the headlines, the cinema listings, what a loaf of bread cost, a short paragraph about the period — the Magazine tier opens it up.

Chapter is for people whose decades have started to talk to each other. Pick three years that matter. Yesterly shows you all three at once, every morning, with a small cultural texture for each.

Not a feed. Not a notification trap. Not a place to optimise yourself. Yesterly does not interpret your past or sell it back to you with insight. It tells you what was on the radio. You tell yourself the rest. That is the trick.
