CAREGIVER · 01
Care that thinks ahead.
A caregiver-first mobile companion for families living with Alzheimer’s and dementia. Medication, mood, vitals, and location — held together by a privacy-first design that runs on the device, not the cloud.
A short tour of the caregiver experience — reminders, location safety, mood check-ins, and the calming activities patients do inside the app.
ReMind is built for both, but it answers to the second. It is not a replacement for care. It is a steadier hand in the work of caring — keeping medication on time, drawing a soft line around the world, listening for the small signs that a day is turning, and sitting quietly when nothing needs to be said.
Dementia is the work of millions of households. Most of that work happens out of sight, performed by family members who learned on the job.

Who provides the care?
Twenty-four hours of caring for someone with dementia, in two voices — the caregiver, and the app that quietly keeps watch.
“First alarm. The day already feels long.”
— Sarah, daughterSoft light, gentle tone. “Good morning, Margaret.”
routine wakeShe doesn’t want her pill. We’ve had this morning before.
— SarahDonepezil 10 mg, on time. Logged: taken. ✓
scheduled reminderPharmacy run. I’ll be twenty minutes.
— Sarah, on the watchMargaret stayed within the home zone. Heart rate 72. Calm.
passive monitoringShe seems quieter today. Hard to say.
— SarahA gentle check-in, not a survey. She tapped: okay.
mood logThe watch buzzes on my wrist before I’ve finished my tea.
— SarahPacing pattern detected. Suggested: a familiar voice memo.
MoodAI signalWe watched the same show again. She laughed in the same place.
— SarahMemory game finished: 4 of 5. Up from yesterday.
cognitive activityShe’s asleep. So am I, almost.
— SarahAll vitals normal. Geofence armed. Goodnight, Margaret.
night modeNo fictional patient was used in the making of this page. Sarah and Margaret are stand-ins for the millions of dyads ReMind is built for — the moments are drawn from caregiver interviews conducted during analysis.
Caregivers draw familiar zones — home, the garden, a daughter’s house. ReMind quietly notes when those lines are crossed, and only then. Live location isn’t surveillance; it’s the answer to a question already on the caregiver’s mind.
A single check-in lies. MoodAI watches the shape of a week — engagement with games, response time to reminders, the rhythm of replies — and surfaces a small note when the curve starts to bend. Not a diagnosis. A nudge worth knowing.
The activities inside ReMind aren’t about scores. They’re short, familiar exercises — matching pairs, gentle puzzles, a song to finish — designed to settle a restless afternoon and give the caregiver fifteen quiet minutes back.
ReMind’s privacy stance was the first design decision, not the last. Four commitments anchor the system.
MoodAI’s pattern detection, geofence calculations, and vitals interpretation run locally. Your phone is the brain, not a relay to ours.
What travels between the app and Firebase is protected by TLS 1.3. What stays on the device is processed locally. Cloud-stored data is encrypted at rest with AES-256.
There is no advertising surface in ReMind. There is no data brokerage. There is no “trusted partner” receiving anonymised exhaust.
Family members see only what the caregiver chooses to share. Each toggle is a sentence in plain language, not a checkbox in a settings tree.
