Yesterdays Weather is a side project to solve a specific problem– I wanted to know the temperature relative to yesterday... a time I can remember.
Instead of “It’s 63°F,” Yesterdays Weather says “It’s 6 degrees warmer than yesterday.” The service compares the temperature, humidity, cloudiness and more to the same time one day earlier.
In 2013 I named, branded and built an iOS app. It’s still available in Apple’s app store, and there are people that use it every day, but in 2014 I built an updated, installable web app version at app.yesterdaysweather.com.
The next version will use a chat interface, but it’s just a prototype until I find some time to code it. It will be fun to experiment with a conversational UI and some light AI stuff. The sentence format itself requires a bit of basic AI, but answering open ended queries well will be more challenging.
