To us swimmers, water temperature is important.

One cold day, I was taking the temperature at the pool when asked "Do you log your readings anywhere?". Except for my Strava activity descriptions, I didn't.

Wouldn't that be a good idea? So, I got thinking and talking to people. Within days, the idea became live readings for pools and lakes so that nobody ever had to take a reading or share a log and you'd know what you're in for before leaving your cosy home.

This wasn't done anywhere. I found that, some pools and lakes have set up bespoke systems to show current temperature. Others, show the current temperature on their websites, but with systems that require manual input. It was complicated.

Until now...
