A local-first care-record companion for family caregivers — live at veai.jp/carequest.
Records a care session in under 10 seconds with no account required. Data lives in localStorage; cloud backup is opt-in via Amazon Cognito.
Care Quest lets family caregivers log daily care activities through a single tap — no typing required. It tracks energy levels, rest-mode days, and a weekly look-back, and surfaces a gentle prompt to a support helpline when low-energy days accumulate. The "Tomoshibi" (Candlelight) widget shows how many caregivers recorded today, using live aggregated data, so no caregiver feels alone.
