The days between appointments, finally visible.
Kella is a daily check-in for people in supervised care. Your swelling and how you feel, your watch's night, and what you ate, did and had done, in one picture that you and your clinical team both see.
Try the check-in on the right. It is a working slice of the app and nothing is saved.
Daily check-inHow does today feel?
Thirty seconds, once a day
Two sliders and a tap or two, just two taps once a wearable is linked, then your Flow Score for the day, a habits score out of 100, never a medical measure. Miss a day and nothing resets.
Your night, filled in for you
Connect a Fitbit or Pixel Watch and your heart-rate variability, resting heart rate, sleep, steps and workouts arrive through the day, and become a Recovery score, measured against your own baseline, that shapes what Kella suggests.
The same picture as your clinician
Your practitioner sees exactly what you see, so every appointment starts with the full story rather than a memory of it.
Your treatments, marked on your own line
Sleep and swelling over 7, 30 or 90 days, with every logged treatment shown where it happened. Patterns you would never notice day to day become plain.
What seems to help, for you
For each treatment or activity you log, Kella compares the day and night that follow with your own usual readings. After three logs of the same thing, the comparison appears. These are gentle patterns, not clinical conclusions, your practitioner helps you read them.

Supervised care, with the days in between
Kella was built inside a working clinic. Your team sees each patient's daily picture, with raised swelling and poor sleep flagged for review first, and lab results and plain-English reports released to the patient only after two clinicians have signed them off.
Things people ask before they start
How long does the daily check-in take?
Under a minute. Two taps if a watch is linked, five gentle sliders if not. You can save after the first step and come back to the rest.
Do I need a Fitbit or Pixel Watch?
No. Kella works fully on the check-in alone. A watch adds your sleep, heart rate, recovery and steps automatically, and unlocks the Recovery score.
What is the Flow Score?
A gentle habits score out of 100 built from what you log each day: water, movement, sleep, food, gut, recovery and your routine. It is a guide, not a medical measure.
Who can see what I record?
You, and the clinical team you have consented to. Nobody else. Your data is held in the EU and is never sold or used for advertising.
How do lab results work?
Your clinic adds your results, or you upload your own. Two clinicians check and sign off a plain-English report before it is released to you, so what you read has been read first.
Is Kella a medical device or a diagnosis tool?
No. Kella records and shows patterns for you and your clinical team. It does not diagnose, prescribe or monitor you around the clock. If you feel unwell, contact your GP or call 111.
Do I get anything for keeping it up?
Yes. Wearing your watch and keeping your log up to date earns Kella Rewards points towards treatment upgrades, product credit, money off, or a charity donation in your name. No streaks, nothing to lose, and you can turn it off any time.
How do I get an account?
Your practitioner invites you after an appointment. If you are a clinic, use the enquiry form on the For clinics page.
