Caregiver Shift Handoff Journal

4.20

Derivation Chain

Step 1 Dual planning: parent care + personal retirement
→
Step 2 Caregiving burden conflicts among siblings
→
Step 3 Information loss during shift caregiving handoffs

Problem

When 2-3 siblings take turns caring for a parent in their 80s, daily care information — medication intake, meal amounts, bowel status, mood changes — gets scattered across KakaoTalk messages, causing critical information to be lost during handoffs. During hospital visits, they cannot accurately convey 'last week's condition' to the doctor, reducing care quality. Recurring conflicts arise between siblings over 'you didn't take proper care.'

Solution

A web-based shift caregiving journal. (1) The outgoing caregiver records medication, meals, sleep, bowel movements, and notable observations via a checklist in under 3 minutes. (2) The next caregiver receives an auto-generated summary notification (KakaoTalk integration). (3) Before hospital visits, a one-page PDF summarizing the past 7 days of care can be printed and submitted to the doctor.

Target: Ages 45-55, sharing care of a parent in their 80s with 2-3 siblings, working full-time with significant time constraints
Revenue Model: Free basic plan (up to 3 family members). ~$3.70/mo (~4,900 KRW) for 5+ family members or when including a professional caregiver. Custom hospital-submission care Report PDF at ~$1.50 (~2,000 KRW) per transaction.
