How it works

Comprising a motion sensor, a click-to-talk button and Amazon Alexa, Sentai allows family members to track activity of older relatives via an app and be alerted to a break in routine. It is designed to act as a gentle task reminder and wellbeing device for those wanting to live a more independent life while providing reassurance and visibility for families.

My mum is fiercely independent but needs some help. I've got my brother, sister and mum's carer connected to Sentai and it's making life a lot easier for us all.

Loving my Sentai, I don't know anything about technology but it's so easy to use and reassuring to have a presence when my family can't be there.

I’ve set up reminders for my medication, it’s one of the things I forget the most and I find it really useful when Grace (one of Sentai’s voices) lets me know it’s time to take them.

I know my friends worry about me a lot, but having Sentai has given them confidence I’m taking my medication at the right time, and eating and drinking regularly too.

Kay, Age Space review

"A very useful, friendly companion for people living on their own to help them through their day and to provide reassurance to their family.

For me, medication reminders was the most useful thing Grace did. It's hard enough remembering what day it is sometimes let alone which pill I have to take on an empty stomach. I didn't have to write anything down or remember - Grace just let me know what and when"
