Low-data views first
Sparse readings were the normal state.
Make individual readings useful immediately; reveal richer trends as records accumulate instead of presenting an empty sensor-style chart.

Research & Discovery
Designing for a trickle of data.
Moving from general wellness to diabetes management meant rethinking the daily experience. My competitive research asked what people with type 2 diabetes in India already used—and where Kina could offer useful support.
One week. Two ways of recording glucose.
A sensor collects readings automatically. A finger-prick meter records only the moments someone tests. Kina had to work with the second pattern, too.
Continuous sensor
Automatic capture throughout the day
2,016readings in one week
288 readings per day × 7 days
A continuous picture. Frequent readings provide the data needed for detailed daily glucose trends.

The sparse-data scenario in the research
Four snapshots, not a daily curve. The app knows those recorded moments—not what happened between them.
What this changed in Kina
Make a few readings useful. Don’t require a sensor’s worth of data.
Start with clear individual records and useful low-data states. Add richer trends as more readings arrive, without filling the gaps with an invented glucose curve.
Research scenarios, not a testing recommendation. The weekly sensor total is calculated from the document’s 288 readings per day; actual recording frequency varies.

Nov 2020
Libre launched in India
Continuous sensing was available but new and premium-priced; a sensor-first experience would narrow reach.
Who pays changes what the product can be.
Five business models explained the competitive landscape better than a flat feature list. This is the August 2021 decision context, not a current ranking.
| Model & examples | Who pays | What it meant for the experience |
|---|---|---|
| Free loggersmySugr · Glucose Buddy · Diabetes:M | Free / small subscription | Self-serve records and reports; the user still does the logging work. |
| Device ecosystemsFreeStyle LibreLink · OneTouch Reveal · Glooko | Hardware purchase | Capture and visualisation built around an owned meter or sensor. |
| Employer programmesLivongo · Omada · Virta | Employer / health plan | Devices, supplies, and human coaching funded by a payer—not the same economics as Indian self-pay care. |
| Digital therapeuticsBeatO · Fitterfly · Breathe · Zyla | Patient / programme payer | Connected monitoring or structured support, often with people delivering the service. |
| Horizontal wellnessHealthifyMe · Cult.fit · Practo | Consumer subscription | Broad lifestyle support competing for the same attention, without the same diabetes-specific depth. |
The opportunity for Kina
Add condition-specific depth to an existing wellness foundation.
Evolut already connected workouts, meal plans, wearables, consultations, and records. Kina aimed to add approachable diabetes tracking and contextual guidance without making every interaction depend on a paid coach.
This was the intended position—not proof of clinical equivalence to coached programmes. Conversational support needed clear limits and a route to a real clinician.

Key decisions
Make it clear.
Make it easier to return.
Seven decisions shaped Kina around three priorities: understandable records, lighter daily tasks, and support that fits real life.
Understand the readings
Useful information, even when there is little data.
Familiar, qualified HbA1c
A familiar lab value anchored the conversation.
Prioritise lab records and distinguish any estimate from a measured result. Do not imply sensor-only metrics can be derived from sparse logs.
Reduce daily effort
Make the recurring tasks easier to keep doing.
A five-second logging target
Every manual entry asks for effort.
Keep the entry path short and the log types recognisable. Five seconds was a design target, not a measured usability result.
Portions, not calculations
Shared Indian meals do not fit a packaged-food model.
Frame nutrition guidance around familiar meals and portions rather than requiring people to calculate every gram of carbohydrate.
Support the person
Leave room for questions, family, and familiar language.
Chat with a clear next step
People may not know what to ask.
Use chat as an entry point, then hand off to logs, trends, reminders, and consultations. Keep the assistant’s limits visible.
Include the carer
A spouse or adult child may manage the routine.
Treat shared oversight and family support as part of the experience, not an edge case reserved for the patient’s own phone.
Build on local languages
Language changes who can participate.
Carry familiar language into condition-management guidance. The existing wellness platform supported eight Indian languages, an advantage to build on rather than a new Kina launch claim.
These are research-led design commitments, not independently validated launch capabilities.

Personal records. A clearer view.
Kina brings glucose records, medication schedules, diet logs, and consultation access into a consistent mobile experience. Overview, history, and consultation remain distinct so each task has a clear home.

Understand the trend
High, average, and low readings sit alongside the chart. Time-range controls and labelled states help people review their records without relying on colour alone.
Kina product walkthrough
Wearable experience
Built for a glance.
The watch keeps the workout interaction small: start, choose an activity, then review a few key metrics. It complements the richer mobile experience rather than compressing every feature onto the wrist.
Start a workout
One primary action makes the entry point immediately recognisable.
Choose an activity
Icons and labels pair a quick visual cue with an explicit activity name.
Review the session
A focused summary surfaces workout metrics without competing navigation.

Branding
From a glucose symbol to a familiar character.
The client wanted the diabetes module within Evolut Wellness to feel more approachable, engaging, and motivating. The identity evolved from the GlucoLife glucose symbol to Kina, a branded digital character with a more personal presence.
Earlier identity · GlucoLife
Identify the condition.
The drop symbol made the module’s focus on glucose immediately recognisable. Its visual language centred on what people were tracking.
Evolved identity · Kina
Give the experience a personality.
Kina introduced a recognisable character alongside the health-management tools—a friendlier identity designed to encourage people to engage with their daily routine.
Character-led UX & Gamification
The response to the client’s direction was more than a name change: shift the tone from recording a condition to supporting a person. Kina gave the module a consistent character around which encouragement and habit-building interactions could be framed.
- Approachable
- A named character creates a more personal introduction to the module.
- Engaging
- A recognisable identity connects the experience across repeat visits.
- Motivating
- A character-led direction supports playful encouragement around everyday participation—not judgement of health readings.
These describe the intended experience, not measured engagement or health outcomes. The character supports the interface; it does not replace clinical guidance.
Social media creatives
Kina’s character-led identity extended beyond the app into a series of 11 marketing creatives for the diabetes management module. From the first teaser to feature introductions, the campaign paired a familiar character with direct, approachable messages. These creatives were published on Evolut’s Facebook and Instagram.
