I feel truly sorry for older folks navigating apps/logins/passwords/etc.

Their experience is often utter shit.

Two examples:

1. Often older folks have their screen zoom maxed out for readability. Extreme zoom will often place critical fields and buttons off-screen - making the app useless.

2. Fingers and hands of older folks often tremble. So imagine holding in your trembling left hand your phone, while you're trying to hit a target with your trembling right finger. All while standing in line to get a discount on your groceries.
