I have tried it out for various things but the one I rely on most is "call and leave a message then get that message emailed to me" I ONLY use this feature for logging my work tasks and client visits throughout the day. Basically I always forget to record my time spent at various locations or when I do extra work outside of scheduled hours. I have ifttt as a contact in my phone named Bender. When I'm in my car going to/from client visits I can tell my phone "Call Bender" and I tell Bender what I'm up to, and anything I might want to note about times, mileage, etc. Hugely useful fallback for me so that at the end of the month I search my email for "voice memo" and I can process everything I haven't already captured. Especially when I have to run around putting out fires in multiple places I can easily forget exactly what I did and in what order.
