Security apps

Hey there, my sister has a bit of problem. She has to work late night for a days next month and she can't drive coz she's pregnant. Her company has offered to provide a cab and she has accepted it. But now she is little scared of the safety of travelling alone in a cab late at night. I suggested her to use a personal safety app (… ) and carry a pepper spray. Is there any other gadget she can use for safety purposes?

    Why cant she drive being pregnant?

    As far as safety precautions see if there is a self-defense class in the area she could sign up for.
