Luminate (V1 archive)
Journey detection
Walking, running, cycling, road and public transport are inferred from location, motion and movement patterns.
Personal air quality, quietly understood
The air you meet every day.
Luminate turns the places you spend time and the journeys between them into a clear, personal picture of air pollution exposure.

01 / YOUR DAY
A diary you never have to write.
Luminate works quietly in the background, organising movement and time at places into a timeline that makes sense at a glance.
Places that become familiar
Confirm Home, Work and the places that matter. Luminate learns recurring locations while keeping you in control of every confirmation.
A map with memory
See the route for each journey, focus any part of your day, and revisit previous days from the calendar.
02 / EXPOSURE
Air quality matched to where you actually were.
A city-wide reading cannot describe a personal day. Luminate calculates modelled exposure for confirmed journeys and stops, including the time spent at home, work and everywhere in between.
Four pollutants · every confirmed segment
See where the day changed.
NO₂, O₃, PM₁₀ and PM₂.₅ are shown for each journey and stop in a shared colour language, making high and low moments easy to spot.
- Route-aware estimates use timed coordinates and travel mode
- Stationary periods are included, not treated as missing time
- Overall values are time-weighted across the day
Two ways to understand exposure
Concentration and dose.
Switch between average concentration and modelled dose. The first describes the air; the second adds the duration and activity context that shaped your total exposure.
- Compare a short high-exposure journey with a long lower-exposure stay
- Separate journey and place contributions
- Coverage is stated when parts of a period are still unconfirmed

03 / INSIGHTS
One day is useful. A pattern can change a habit.
Move from today's detail to a week, month, 90 days or a custom period. Compare travel modes, recurring places, high and low moments, and change against the previous period.

Your exposure story, over time.
Understand which journeys contribute most, where you spend your time and whether your personal exposure is moving up or down.
- Journey and place ledgers by pollutant
- Highest and lowest episodes link back to the original day
- Walking, cycling and other activity totals alongside exposure

Natural-language queries · computed locally
Ask your own data.
“When was my exposure highest?” “Was cycling cleaner than the Tube?” Ask Luminate translates everyday questions into structured queries over your timeline — not generic advice from the internet.
- Questions use the dates, places, modes and pollutants in your history
- Answers include their time period and data coverage
- Designed to execute against on-device data
Which commute gave me the lowest NO₂ last month?

04 / UNDER THE HOOD
Sophisticated enough to disappear.
The seamless experience is supported by several systems working together: sensing, learning, exposure modelling, battery policy and a local-first data layer.
Battery-aware sampling
Sampling responds to movement, battery state and device conditions rather than treating every minute alike.
Movement and place models
On-device signals classify journeys while confirmed recurring places build durable local context.
Route and stop exposure
Timed routes and stationary windows are matched to modelled pollutant fields for average and dose.
From records to insight
Daily segments become comparable weeks and months without losing the journey that produced each result.
Privacy by design
Your timeline stays with you.
Luminate does not require an account. Its detailed timeline is stored on the device, and exposure requests are sent only for ended segments that you explicitly confirm. You remain in control of location access and recording.
