How you ship it
Your product. Your brand. Personalised nutrition.
ONE works behind your application or portal. Your customers interact with your product. You own the user experience, the brand and the customer relationship — ONE provides the nutrition infrastructure underneath.
Who builds with ONE?
Built for companies building health, fitness, coaching and wellness products.
The primary audience is not consumers looking for a nutrition app. It is product teams that need personalised nutrition functionality inside the experiences they already own.
02
Fitness and coaching
Pair training programmes with meal plans that respect goals, preferences and restrictions.
03
Nutrition and diet products
Power planning, logging and recommendations behind your own brand experience.
04

05
Digital health companies
Embed nutrition infrastructure into broader digital health journeys.
06
Consumer apps adding nutrition
Extend an existing product with personalised nutrition functionality.
Not just a food API
Personalised nutrition is more than a recipe database.
Most food APIs provide food search, recipes, calorie information and nutritional data. ONE goes further — it starts with the person.

The ONE lifecycle
Understand → Plan → Track → Analyse → Learn → Optimise
ONE uses the nutritional profile to support the full nutrition lifecycle — so partners can ship personalised food experiences without assembling every subsystem themselves.
01
Understand
Capture the person's nutritional requirements and preferences.
02
Plan
Generate personalised meal plans from that profile.
03
Track
Log foods and meals against the targets you define.
04
Analyse
Understand intake, progress and nutritional patterns over time.
05
Learn
Adapt to preferences and behaviours so recommendations improve.
06
Optimise
Refine future plans around clearer nutritional priorities.
Capabilities
What the nutrition infrastructure covers.
01
Nutritional profiles
Start with the person — requirements, goals, allergies, preferences and history that persist over time.
02
Allergies & restrictions
Respect what users must avoid — and what they simply prefer — when generating recommendations.
03
Nutrient goals
Focus plans on nutritional priorities such as increasing iron intake or meeting protein targets.
04
Meal planning
Generate personalised single-day or multi-day meal plans that fit each user's profile.
05
Food logging & analysis
Let users log meals, then analyse intake and progress toward nutritional goals.
06
Recommendations & substitutions
Recommend recipes and suggest alternatives when a food is excluded or unavailable.
What can ONE power?
Experiences your customers can actually use.
More commercially relevant than the underlying engine alone — these are the product experiences ONE helps you ship.
01
Personalised meal planning
Generate meal plans based on each user's requirements, preferences and goals.
02
Food logging
Allow users to log meals and food consumption against their nutritional profile.

Nutrition coaching
Give coaches and platforms the tools to support personalised nutritional programmes.
04
Nutrient optimisation
Help users focus on specific nutritional priorities such as iron, protein or other nutrients.
05
Recipe recommendations
Recommend recipes that fit the user's requirements.
06
Intelligent substitutions
Suggest alternatives when a food is excluded or unavailable.

Ongoing adaptation
Use history and preferences to improve future recommendations.

Why ONE?
Why build nutrition yourself?
Building personalised nutrition functionality requires much more than a recipe API.

ONE provides the nutrition infrastructure so your team can focus on the product experience your customers actually use.
Optional integration
Two independent platforms. One optional path to richer personalisation.
ONE works independently. Add WearSightful when wearable and health-data context becomes part of your product roadmap — or integrate other aggregators on a bespoke basis. You do not need to buy both products.
ONE by OSCA
Personalised nutrition infrastructure.
Nutritional requirements → meal plans → food logging → recommendations
WearSightful
Health and wearable data infrastructure.
Wearable data → normalisation → trends → insights → engagement
Combine when needed
Add wearable and health context to nutrition experiences when your roadmap calls for it.
For product and engineering teams
Built for the teams shipping the next generation of nutrition experiences.
Product teams evaluate the commercial fit. Engineering teams explore the API and SDKs. Both paths lead to the same platform.

How can WearSightful extend ONE?
WearSightful connects and normalises wearable and health data. Combined with ONE, activity, sleep and related signals can enrich personalised nutrition experiences. Clients can also request bespoke integrations with other wearable data aggregation services.
Is ONE a consumer app or a medical device?
