Watching over the user while keeping the family informed

Sentai is different, and redefines new ways to care for someone.

Taking care of the day-to-day, reminding, alerting and talking with the user. Detecting and reporting on what seems normal and what doesn't look quite right.

Unlike other passive devices and alarms on the market Sentai learns from each interaction becoming more and more helpful over time.






Sentai reinvents the way that we care for our senior loved ones

Talk to me

Sentai uses voice to communicate with your loved one and the user simply talks back. No technical apps or smart phones for the older person to worry about.

No remembering what to say, simply click a button and Sentai will be there to serve.

Remind me

As well as important things such as medication, meal times and making sure they are drinking enough, the family can send customised reminders to the older person ranging from making sure they're ready for a visitor, to putting out the bins for collection.

Connect me

A connected family results in peace of mind and better quality interactions.

Sentai gives you the insight that the user is moving about the house and carrying on with their regular day, but will send alerts to the family if a regular pattern is broken.

I can time my visits for a cup of tea when I know that he is up and about.'

Chloe, 35​ Worcestershire

‘After 20 years of providing care, the fact I can check dad is up & about and taken his pills -  at the tap of an app is such a relief’​
