About Rhem Labs
What Is Rhem
Rhem is a tabletop robot built for the everyday side of care. It stands about 14 inches tall, carries a 10 inch touchscreen, and stays on a table or counter rather than moving around the house. You talk to it the way you would talk to a person, and it answers out loud. It is an AI companion robot for the household, not a medical system.
The job it takes on is smaller than a caregiver's and broader than a smart speaker's. Rhem Labs built it for older adults and for the family members shopping for a robot for aging parents. Rhem records blood pressure, heart rate, blood oxygen, and body temperature readings, keeps them in a dated history, and shares what you allow with family through a companion app. It also sets medication reminders, places calls, books appointments, orders groceries, and runs games or karaoke when nobody needs anything urgent.
Two versions ship: Rhem Cloud at $1,099 and Rhem Local at $1,299. Cloud sends conversations to online AI models. Local runs most everyday conversations on the robot itself. Calls, websites, family updates, and remote alerts still need the internet. Both include one Halo, a wall or ceiling mounted radar sensor that watches for falls without a camera, and both include 24 months of Rhem Plus. After that, Plus costs $19 a month if you renew. Basic keeps working with AI usage limits. There is also a rental at $99 a month.
The limits are worth stating plainly. Rhem is not a medical device, its readings are non-medical estimates, and it cannot diagnose anything or replace a caregiver. It does not call 911. It needs home Wi-Fi and has no cellular radio. Orders are open in the United States only, and Founder Edition preorders are expected to ship from California between January 20 and 31, 2027.
Getting Started
- Order Rhem in Cloud or Local configuration from rhem.ai. A $99 monthly rental is available if you would rather not pay the full price up front.
- Add the Wi-Fi details for the home where Rhem will sit in My orders. If the robot is a gift, you can record a welcome message at the same time.
- Place Rhem on a table near a power outlet and mount the Halo on a wall or ceiling where falls are most likely, such as a hallway between the bedroom and bathroom.
- Set up the family app with the person who will use Rhem. Permissions decide which readings, reminders, and help requests relatives can see.
- Run a wellness check-in together and confirm that alerts reach at least two contacts. Phone setup help is included if the first session gets stuck.

Key features
Wellness Readings in Under a Minute
Rhem uses optical sensors and remote photoplethysmography to estimate more than 100 health markers, including blood pressure, heart rate, blood oxygen, and body temperature. Each reading goes into a dated history you can scroll through or share, so blood pressure monitoring turns into a record instead of a one-off number. Rhem Labs labels these as non-medical algorithm estimates, so they work as a trend line between doctor visits, not as a diagnosis.
Halo Fall Detection Without a Camera
The included Halo is a separate radar sensor that mounts on a wall or ceiling. It looks for falls in the area you configure and sends an alert to the family app when something looks wrong. There is no camera and no microphone in the unit, which matters in a bathroom hallway where people expect privacy. That makes Rhem a fall detection robot that works without a wearable.
Voice-First Help With Calls and Errands
You can ask Rhem to book an appointment, check pharmacy hours, or order groceries. It navigates websites and places calls, then reports what it found. You set the shopping budget and approve purchases, and Rhem texts or asks when it needs a detail it cannot guess.
Medication and Routine Reminders That Follow Up
Reminders are not a one-time chime. Rhem checks back if nothing happens, can call the person while they are out, and can bring a family member into the follow-up. Rhem Labs states clearly that a reply does not prove medicine was taken, so the feature supports a routine rather than enforcing one.
Family App With Shared Readings and Alerts
The family care app shows shared health readings, reminders, and help requests to relatives the user has approved. It also receives Halo fall alerts. Family can live in another city or another country, and everyone sees the same record rather than a summary passed along by phone.
Cloud or Local Processing and Privacy Controls
Cloud handles conversations with online AI models. Local keeps most everyday conversations and basic AI tasks on the robot. On both versions the camera stays off by default with an indicator when it is active, live family video calls are not recorded, data is encrypted in transit and at rest, and Rhem Labs says personal data is never used to train general AI models or target ads.
Pros and cons
Pros
- Health readings, reminders, errands, and family alerts live in one device instead of four separate apps.
- Halo uses radar rather than a camera, so fall detection works in rooms where a camera would feel intrusive.
- Buying outright removes the monthly fee. Basic keeps fall detection and family alerts, and Plus is optional at $19 a month after the first 24 months.
- Voice-first design suits people who never got comfortable with a smartphone, and the 10 inch screen helps when they do want to read something.
- Local processing gives privacy-minded households a way to keep everyday conversations on the device.
Cons
- Rhem does not move. It cannot fetch a glass of water, help someone up, or check on a room, so it does not cover the physical part of caregiving.
- No emergency dispatch. Alerts go to family contacts only, with no professional monitoring team and no 911 call, so a second way to get help is still necessary.
- Wi-Fi is mandatory and there is no cellular option, which rules out homes with unreliable internet.
- U.S. orders only, with Founder Edition shipping expected in January 2027, so buyers outside the country have no timeline yet.
