Know the carbon cost of every trip you take.
Atmos quietly tracks how you move — car, train, bike, walk — and turns it into a clear picture of your daily footprint. No spreadsheets. No guesswork.
How it works
Three quiet steps. No homework.
Atmos runs in the background. You go about your day. We do the math and the modelling — you get the picture.
Move like you normally do
Open the app once. From then on, Atmos detects when you're walking, biking, driving, or on transit — using motion sensors, not constant GPS.
See trips appear automatically
Each trip is labelled with mode, distance, and a CO₂ estimate calibrated to your country's grid. Tweak anything that's off in one tap.
Get one useful nudge a week
No streaks. No shaming. Just a quiet weekly read of your patterns, plus one realistic switch you could try — modelled against your own routes.
The Atmos dashboard
Your week, your modes, your numbers.
Every screen built around one question: did today move me closer to where I want to be? One glance answers it.
Dashboard
What makes it work
Smart where it counts. Quiet everywhere else.
Auto-detection
On-device motion classifiers tell walking from cycling from driving from transit — without draining your battery or pinging GPS every minute.
Honest math
CO₂ estimates use country-specific grid mixes, vehicle class, and time of day — not generic averages. Methodology is documented, not magic.
One weekly nudge
Friday afternoon: one tip, modelled against your own week. Not "drive less." Specifically: "the 8:12 Caltrain would cut your Friday in half."
Yours, on device
Trip data never leaves your phone unless you choose to back it up. No ad tech. No third-party SDKs.
The dashboard
A clean web view of the same data: weekly trend, transport mix, full trip log, and analytics deep-dives. Export to CSV anytime.
Goals that flex
Set a daily cap. Atmos adjusts to your routine: harder on a quiet week, gentler when life happens. Streaks without the pressure.
Weekly insights
The part nobody else gets right.
Most apps drown you in charts. Atmos reads your week and surfaces three things, max: a pattern, a tip, and anything unusual. That's the whole feed.
Streak
12-day tracking streak
You've logged trips every day for nearly two weeks — your longest yet. Last streak was 8 days in April.
Tip
Try the train on Fridays
Your Friday commute is 40% higher than weekday average. The 8:12 Caltrain would cut it in half — about 3.2 kg saved per week.
Anomaly
Unusual spike on Friday
7.9 kg CO₂ on May 16 — 58% above your weekly average. Two longer car trips (Home → Stinson, return) contributed most.
