A:AnswerI don't think you have a calculator option on this one. But it does have an alarm/stop watch/timer system. I have not yet been able to sync it to my alarms on my cell. You can contact Fitbit and they will answer all your questions for you. Very helpful when I used them.
A:AnswerYou can have your watch on anywhere. It you are responding to text messages, you need your phone. I go in walks and don’t have my phone on me and it works just fine.
A:AnswerIt is definitely waterproof. I've never been snorkeling so I can't exactly say it will survive that trip but you can always reach out to the FitBit team with any questions. Even the Social Community within FitBit would be happy to help.
