From our pilot families*
“You can tell the rhem Labs team put real care into their product from the onboarding alone. The tutorial is so simple and intuitive — even I got rhem running for my mother in 5 minutes!”
“It's pretty cool how accurate the sensors on rhem are — and having almost 10 of them is amazing for my day to day.”
“rhem's alert, SOS, and remote check-in features have changed my relationship with my parents. We feel more at ease with them living alone, and we've genuinely gotten closer. Thank you, rhem — you guys need to try it!”
“Like everyone else, we were super skeptical when the rhem team came to us for their pilot program. The SOS feature piqued our interest — and throughout the month with rhem, we've been continuously amazed by the features.”
“My hip was acting up one day and I collapsed downstairs. rhem quickly alerted my son after I called out my alert word and they were at the house within 10 minutes. Simply amazing.”
*In early 2026 we placed Rhem prototypes in 8 households for 30 days.

FAQ
Daily health checks
How does Rhem measure my parents' vitals?
Rhem tracks vitals using its medical-grade built-in sensors. It can measure blood pressure, heart rate, blood oxygen (SpO₂), and respiratory rate — quietly, at home, every day.
How does Rhem know when something changes?
Rhem learns what's normal for your parent over time. When a reading drifts from their usual pattern — blood pressure trending up, breathing changing at night — it flags the change in the family app so you can act on it early. Rhem supports wellness awareness; it doesn't diagnose conditions or replace their doctor.
How does Rhem measure our air quality?
Rhem has built-in air sensors that monitor indoor air for particulate matter, CO₂, formaldehyde, gas leaks, and other environmental risks. If levels become unsafe, it can trigger a safety alert so your family knows.
Safety & alerts
How does Rhem detect falls?
Rhem senses falls using a radar sensor instead of a camera lens. If it senses a fall or someone lying on the floor for an unusually long time, it can alert the family contacts you've set up.
What happens if someone falls?
If Rhem detects a fall or someone lying down for an unusually long time, it can start a safety alert. The app then notifies the emergency contacts you've chosen so the right people are told quickly. If it's a false alarm, the person at home or any contact can cancel it.
What happens if there is a gas leak?
If Rhem's air sensors detect a gas leak or other unsafe air levels, it can trigger a safety alert to let your family know something is wrong.
Can Rhem call 911?
When Rhem detects a possible emergency, it starts a safety-alert flow that calls and notifies the emergency contacts you've set up. Rhem does not call 911 or dispatch professional responders. It's a family safety-alert feature designed to reach your chosen people quickly, not a replacement for emergency services.
What is the safety word?
You can set a custom safety word that triggers a family alert. When it activates, the app calls and notifies the emergency contacts you've chosen so the right people know quickly. This is a family safety-alert feature, not a replacement for 911 or professional emergency services. If it's triggered by mistake, the person at home or any contact can cancel it.
Living with Rhem
My mom isn't tech-savvy. Will she be able to use it?
She's exactly who Rhem is made for. Rhem's tutorial was designed alongside doctors to be as simple as possible and only requires the person to talk to Rhem for setup. After that, she just talks to Rhem — asking questions, hearing reminders read aloud, getting answers — with no app for her to manage.
Can I set it up for my parent even if I don't live with them?
Yes. You do the setup from the companion app on your own phone — connect Rhem to Wi-Fi, link the account, and create profiles — so your parent never has to handle the technical side. Our support team can help with setup, account linking, and updates, so you're not doing it alone.
How does Rhem handle our data privacy?
Its core safety sensing uses radar, so it can detect falls and movement without filming the room. Camera features, like wellness image capture, only run when you choose to use them — there's no always-on lens. And because processing happens on the device itself, interactions stay fast and your family's health data stays closer to home.
What AI does Rhem use?
Rhem runs an onboard AI assistant that powers natural voice conversation, answers questions, reads reminders aloud, and helps explain readings in plain language. It uses a dedicated AI chip inside the device, so many tasks run on the robot itself for faster, more private responses. Rhem is designed for companionship, reminders, and general health-support conversations — not medical diagnosis.
What does Rhem cost? Are there any hidden fees?
Rhem's expected launch price is $1,099. Kickstarter backers will get it for $799, and right now you can reserve the $599 early price — $500 below launch — with a fully refundable $1 deposit that counts toward your Rhem. No subscription is required to use Rhem. Optional in-app purchases are available for things like expression packs, advanced health AI models, telehealth access, and more.
Reserving Rhem
Is the $1 deposit refundable?
Yes — fully refundable anytime before your Rhem ships, in one click. No questions asked, nothing owed.
Does reserving commit me to buying?
No. Your $1 holds your spot and locks in the $599 early price, but you're never obligated to complete the purchase. If it's not right for your family, your deposit comes straight back.
What if the price changes before launch?
Your price can't go up. Reserving locks in $599 — $500 below the expected $1,099 launch price — and holds it against any future increase.
When will my Rhem arrive?
We open orders on July 20 through Kickstarter, where early supporters get the best price, and your reservation gives you first notice. Rhem ships early November, with reservations fulfilled in order.
