I absolutely love it, but I'm a total data geek. Just as one anecdotal thing that I got out of the app: 2 weekends ago was ridiculously nice in San Francisco. If you live in SF it was a weird 2 days of perfect weather in the midst of an otherwise fairly cold winter. If you look on the charts there it pops out immediately. There's a huge spike for Feb 5 and 6. Suddenly it jumped from low 60s/high 50s to a nice 72 degrees and then immediately right back down again after the weekend. It was really cool to see my personal experience of the weather quantified like that. One quick suggestion: show the day of week in the tooltip where you show the date (when zoomed into showing single days at a time obviously). That would make it easier for me to relate the data to my memory of the weather.
