Technology is complex
Mobile reminder apps do not really serve the
purpose because most elders are technology-phobic
and most apps are NOT elder-friendly. In fact, in
many cases they end up becoming another point of
stress.
Constant tending to the App
Constant tending to the App to ensure new
reminders are fed, changing settings, reinstalling
new versions, adjusting to new version UIs. All of
this is too much for the elderly.
Mismanagement by the senior
Seniors quite frequently tend to push the wrong buttons, some times due to confusion
or physical weakness or tremors. Icons tend to get deleted scaring them witless
leading to another stressful call for help.
