Nico vs Zoe: what's the difference?
Zoe built massive awareness for metabolic health in the UK, and we give them credit for that. Millions of people now understand that food affects their body differently based on their biology. That's a good thing. Where things diverge is what Zoe does now, what it does with that insight and what Nico does with it.
What Zoe offers now
Zoe sells an at-home test kit: a blood fat test and a gut microbiome analysis. From this, you get personalised meal scores and dietary recommendations through their app. The test is a one-time snapshot; the app subscription continues monthly.
The CGM component was central to Zoe's early marketing. The yellow sensor on the arm became their brand image. But they don't use CGM's any more. There's no ongoing glucose monitoring.
Why Zoe moved away from CGMs
Zoe's model is built around gut microbiome testing, which is their proprietary research advantage. The CGM was always a data-collection tool for their algorithm, not the core product. As their business scaled, the CGM became a cost and logistics problem: sensors are expensive, supply is constrained, and the gut test alone is a simpler product to sell and ship.
The result is that Zoe's recommendations are increasingly based on gut microbiome data and population models rather than your real-time glucose response. If you came to Zoe because you wanted to understand what food does to your blood sugar, that part of the product has been de-emphasised.
Continuous data vs one off data collection
Nico is built around continuous glucose monitoring as the core product, not a one-time data collection step. You wear a sensor continuously and the AI coaching reads your glucose data in real time: what you ate, how your body responded, what to change, and whether the change worked.
The coaching evolves as your data accumulates. Week one looks different from week eight because your metabolism changes as your habits change. The feedback loop is continuous: eat, see the response, adjust, see the improvement. This is fundamentally different from a two-week test that produces a static set of recommendations.
The core difference
Zoe gives you a snapshot and a set of scores. Nico gives you a continuous feedback loop with coaching that adapts as you change. Zoe's strength is gut microbiome science and population-level research. Nico's strength is real-time metabolic data and personalised behaviour change.
If you want a one-time assessment of your gut health and generalised meal scores, Zoe does that. If you want to see how your body responds to food every day and be coached through changing the patterns that aren't working, that's what Nico is built for.
