I've just started to use Poncho, the weather un-app from Betaworks and, at first glance, I'm impressed.
I have used a bunch of weather apps and, until now, the two in "regular rotation" for me are Dark Sky and the Weather Channel.
Dark Sky is a one-trick pony that executes that trick better than anyone else - it gives you the hyperlocal forecast for the next hour. So, whether you're trying to figure out whether to start the softball game, or whether to bring an umbrella to lunch, no one does it better.
I use the Weather Channel app for the more mundane task of checking the daily weather report before I leave for work in the morning. All I want to know is the current temperature and the expected high and low, along with whether it's gong to rain or snow. And the Weather Channel app does that reasonably well, as do a number of others. But, there's a lot of clutter there that most of us don't need.
Poncho, founded by Kuan Huang, out of Betaworks, gives you the info you need, when you need it, without all that clutter. Poncho simply sends you a text message or email each morning, with a brief snippet telling you what you need to know.
There's no app required. Just go to the Poncho sign up page and answer a few critical questions (where do you live? what time do you wake? do you have pollen allergies?) and tell it whether you want your forecast via email, text or both. And, every morning you'll get a brief forecast with just the info you need to know, right when you need it.
What I love about Poncho is the simplicity. It's like the early days of mobile - when I got my first Blackberry in 2000, there were a number of simple auto-reply services. You'd email a question (e.g. stockprice for a given ticker) and a text response would come back. Sometimes, a brief text message is all that you need. We don't need a robust, full-featured app for every task.
So, we can all learn a lot about development from Poncho.
