I could never get IFTTT to work for me because I needed multiple IF's and they only supported one. For example, I recently tried...
If Time is 5:00p If TempOutside < 70 and Send Alert to "Open Windows"
It sounds like they now support multiple IF's but I can't use that feature in my three free, so I will never know if it would have worked for me. Getting a notice to open my windows when it's 70 outside isn't worth the price of admission but I suspect I could get hooked and find other things that were more useful. Just never happened for me.
