Grandvoice

Inspiration

Every night, adult children like our persona David call a parent who lives alone and ask the same questions: Did you take your pills? What did the doctor say? Often the answer is "I don't remember." Research shows 40 to 80% of what a doctor says is forgotten right away, and 12 to 18% of people over 60 live with mild memory loss. More than 16 million Americans over 65 live alone, and 63 million Americans are family caregivers. We wanted to give older adults a way to hold on to their day, and give their families peace of mind, without asking anyone to type.

What it does

Grandvoice is a talking diary for older adults. Rosa taps one big button and talks about her day. AI turns her words into a journal entry and pulls out what matters: new medicines, symptoms and appointments. If she says "the doctor prescribed me omeprazole 20 mg for 3 days," the medicine lands in her Today list with a Took it button, after she confirms it.

Family app: her son or daughter sees what she chooses to share, gets a gentle alert if she hasn't checked in by 8 PM, and can send love or a reminder. Every request shows up on her side too.
Care home web app: memory care and assisted living staff see resident check ins, medicines and mood, plus insights and billing.
Privacy first: the older adult always decides what is shared, and the app is always free for her.

How we built it

We started by mapping the two sided journey (elder and family) screen by screen, then built a working prototype with three connected surfaces: the elder app, the family app and the care home dashboard. The backend runs on Python (FastAPI on Uvicorn), and [add your frontend and speech to text tools]. We designed the data flow so every action on one side has a visible response on the other, and planned the production stack around HIPAA eligible services (for example AWS Transcribe under a BAA).

Challenges we ran into

Designing for older adults: our first screens were too cluttered. We cut them down to one big button, large text and simple navigation.
Two sided sync: reminders, love notes, medicine check offs and invites had to update instantly on both phones.
Pulling medicines from free speech: people say doses and durations in many ways, so we added a confirm step before anything is saved.
HIPAA: we learned when care homes count as covered entities and designed around business associate agreements, encryption, role based access and resident consent.

Accomplishments that we're proud of

A complete end to end flow: Rosa talks, the medicine appears in her Today list, and David sees it within seconds.
A care home dashboard with resident records, insights, invites and billing, alongside the family app.
A brand and logo (a grandpa holding hands with a grandchild whose face is an open diary) that shows the idea at a glance.

What we learned

Older adults don't want another app to manage. They want to be heard, and to stay independent while keeping family in the loop.
Caregivers carry the medicine burden: 82% of caregivers doing medical tasks manage medications, and about half worry about making mistakes.
Privacy and consent are part of the product, not an add on, especially for people living with memory loss.

What's next for Grandvoice

Prove it: pilots with real families (target: 4+ entries a week per senior) and speech accuracy tests on older voices (target: 95%+ of medicine names right).
Launch: iOS and Android with a Family plan ($9.99 a month), a HIPAA ready backend, and first paying memory care homes in Los Angeles ($6 to $9 per resident a month).
Scale: senior living chain partnerships, PointClickCare integration, and voice support in Spanish, Mandarin and Hindi.
