This study aims to understand digital technology's role in augmenting efficiency in caring for an aging population. More specifically, we looked for mobile applications (apps) that support the activities of multiple family members who share the task of attending to a senior loved one. We screened a total of 4300 apps in the Google Play store. Although we found a plethora of apps about seniors' care, only a small number of them focused on caregiving, reflecting the need for more technological support in co-caregiving.
