Early-stage healthtech

Understanding how
we eat — and helping
us change it.

ReFraem explores how wearable sensing and AI can reveal eating and drinking patterns, helping individuals and coaches gain insight and support healthier habits.

The problem

What you eat matters.
How you eat matters just as much.

Traditional approach
Food diary — manual, delayed, incomplete
Coaches work from memory, not reality
No patterns, no context, no real-time insight
ReFraem
Continuous, passive sensing — no logging required
Objective patterns — what actually happened
AI nudging at the right moment, developed with dietitians

Speed, timing, chewing frequency — these shape digestion, satiety, and behaviour in ways most people never get to see.

Wearables track sleep, steps, heart rate, even glucose. Eating behaviour has always been the gap.

ReFraem makes it visible.

The concept

Making eating patterns visible

A discreet in-ear wearable collects signals during everyday life — no logging, no friction — then AI surfaces meaningful patterns.

Patented sensing technology

One earbud. Wear it during your day. It passively captures chewing, swallowing and micro-movements — automatically, continuously, without any effort from you.

16-hour battery. Charging case. One button to start in the app. That's it.

Signal processing
Raw sensor data is filtered and segmented into eating & drinking events

03
AI & machine learning
AI models identify patterns — speed, frequency, timing and context of eating behaviour
→
04
Personal insights
Your eating pattern mapped and translated into clear, personal understanding via report and daily alerts

05
AI nudging
Real-time prompts developed with dietitians — delivered at the right moment to support healthier choices
Development stage note: The wearable device, machine learning models, and AI nudging components are currently in active development. Pilots are ongoing with early participants. We are transparent about what works and what is still being validated.
The experience

Your eating day, made visible

Timeline
Every eating moment, mapped
See when you ate throughout the day. Each moment plotted so patterns become visible over time — width reflects duration.
Duration & pace
How long, how fast
Chewing frequency reveals whether you're eating mindfully or rushing — one of the strongest predictors of overeating.
Physiological response
Heart rate during meals
Elevated heart rate while eating can signal stress or rushing. ReFraem surfaces this so you can connect body state to eating behaviour.
AI guidance
Contextual, not generic
Late-night snack detected? ReFraem considers context — hunger-driven eating is different from stress snacking, and the guidance reflects that.

ReFraem insight
Evening eating patterns vary per person. Notice how you feel before and after — awareness of hunger and fullness cues is often the first step toward change.

The service

The ReFraem Traject

4–6 weeks of passive eating behaviour data, daily insights, AI nudging and a personal pattern report — delivered in a box to your door. Pioneer programme launching September 2026.

Hardware — delivered to your door
One in-ear device with charging case. 16-hour battery. Wear it during your day. Return after your traject.
Daily insights in your app
Each evening: your eating moments, timing, duration, chewing frequency and speed — automatically mapped. No logging.
AI nudging — in your ear
After a few days, activate gentle voice nudges developed with dietitians. Easy to switch on and off. Never intrusive.
Personal pattern report
At the end of your traject: a full report on your eating behaviour — patterns, tendencies, and what they mean for you.
45-min online dietitian session
Guided only
A ReFraem-trained dietitian who has read your full data report before you speak. Specific advice on your patterns, your pitfalls, what to eat, what to skip, and why.
Pioneer programme
Be among the first.

Limited to 50 pioneer spots. Launching September 2026. Leave your email and we'll notify you first when pre-registration opens — including the pioneer price.

Academic partnerships — actively seeking
Join the founding team

We're looking for early believers

No salaries yet — but a real problem, working prototypes, and a seat at the table from day one. If any of these resonate, we'd love to talk.

ML / Signal processing
Biosignal engineer
Experience with sensor data, classification models, or acoustic signal processing. Interested in applying ML to real-world eating behaviour detection.
