If Mom already has an iPhone, an Apple Watch makes a great addition. She can make payments, stream music and track her fitness. The health benefits of the Series 4 go beyond counting steps: it notifies you of high or irregular heart rhythms that could signal potentially life-threatening conditions like atrial fibrillation; it has a built-in electrocardiogram (ECG or EKG) feature; and it alerts your emergency contacts if you've taken a bad fall. The smaller 40mm size will likely fit most moms.
