Know the ground you stand on.
You read the label on everything you eat. Groundwell is the label for the land — live soil moisture, UV, air quality, and geomagnetic readings for the parks, trails, and shorelines near you, plus a simple timer for your barefoot time outside.
Free · No account · No ads · Your location never leaves your device
You already pay attention. We just point it at the ground.
If you check ingredients, time your sun, filter your water, and know where your food was grown — you'll feel at home here. Groundwell reads public environmental data the way you read a label: openly, skeptically, and in plain language.
Soil-aware
Live soil moisture for your exact area, refreshed with the weather. See whether the ground under that park is dust-dry or holding last night's rain — before you take your shoes off.
Sun-conscious
The live UV index sits right on your home screen, with a plain-language explainer. Know when the sun is gentle and when it's strong, and plan your time outside around it.
Air-aware
US Air Quality Index and the planetary Kp geomagnetic index, sourced from public agencies and explained without jargon. No mystery numbers — tap any metric to see what it means.
A field guide, a timer, and a map — not a feed.
Real places, not pins from nowhere
Parks, trails, beaches, riverbanks, lakes, and peaks near you — drawn from OpenStreetMap, the same community-built map data that powers half the outdoors internet.
A dependable barefoot timer
Start a session, put your phone away. Groundwell logs where you grounded, what surface you stood on, and the conditions at the time — every session counts, even five minutes.
Five-layer map
Flip between grounding spots, soil conductivity, moisture, geomagnetic, and geology layers. Your best-scoring nearby spot is highlighted the moment the map loads.
Earth Connectivity Points
A progression system that rewards time on living ground. Wet grass beats dry pavement; an ocean shoreline beats both. The formula is public — see the table below.
Embossed metal achievements
Bronze, silver, gold, and platinum medals for exploring new terrains and keeping streaks alive. Earned by going outside, not by watching ads.
Your Area Grounding Score
One headline number estimating how favorable nearby ground is for electrical contact right now, computed from live weather and soil moisture. It changes when the weather does.
Twenty minutes is not always twenty minutes.
Earth Connectivity Points scale with the surface you stood on, how moist it was, how much skin touched ground, and the conditions around you. Same clock, very different ground:
| Scenario — 20 minutes, barefoot | Earns about |
|---|---|
| Dry dirt on a summer afternoon | 120 ECP |
| Wet grass after morning rain | 420 ECP |
| Ocean shoreline, feet in the wash | 650 ECP |
ECP measures engagement with the outdoors — it is a game, not a biometric. The full formula and every factor in it are documented in the app's built-in explainer.
No black boxes. Every number has a source you can visit.
Everything Groundwell shows you comes from public, inspectable sources — the same feeds scientists and forecasters use. Tap any metric in the app and it tells you what the number means and where it came from.
Your whereabouts are nobody's business. Including ours.
Groundwell runs entirely on your device. There is no account to create, no cloud profile, no analytics SDK, and no advertising. Your coordinates are used to look up public weather and map data in real time — and they are never stored on a server, because we don't have servers.
What Groundwell is — and isn't
Groundwell provides environmental and geological information for educational purposes. The scores it shows describe the conditions of the ground and air around you, estimated from public soil, weather, and geological data — they are not measurements of your body. Groundwell is not a medical device, does not provide medical advice, diagnosis, or treatment, and makes no health claims. Consult a qualified healthcare provider for any health concern. We think the outdoors is worth your time on its own merits.
