Companion Care Needed - Now Hiring

I need a bit of help for my mother. She needs someone to run errands now and then and occasionally needs transportation (doctor's appointments, errands, etc.). She is having difficulty using her phone to check in with me and my brother and manage other communication, so I'm looking for someone familiar with the iphone specifically and provide assistance with that. There may be other small challenges she could use help for. These should all be easy things to help with. Preferences for a caregiver who is a non-smoker.
