About Kept
An appointment with yourself that you actually keep.
Small enough to do, even on busy days.
Why so small?
Ten minutes you do beat an hour that never comes.
A big promise is the first thing to slip when your day fills up. A small one always fits.
An hour of exercise, every day
A ten-minute walk
What we do differently
Small enough to stick with.
Three choices, straight from the sessions. In their own words.
One promise at a time
“Here it's one single thing. Really just one. One thing. But a very important thing.”
Prototype session participant
Only you feel it
“Other people can see a light too, but a little buzz is just for you.”
Prototype session participant
No judgement
“But you do it all in such a friendly way, and I'm fine with that.”

How we work
Made together, and honest about it.
01
Designed together with 12 women
From the first conversation to the working prototype, at TU Delft.
02
Honest about where we are
Kept is still in development. What you see here may still change.
03
Your data stays with you
Your promise stays on your phone. The pendant measures nothing about your body.
04
Made to last
Replace the battery yourself with the service kit, or have a jeweller do it.
From the sessions
Word for word, from the recordings.
Participants, not customers: Kept is still in development.
