Trupin is a layered map of your area. This page covers the common questions — you can also open the map and explore.
Trupin is a layered map of your area — it brings the things worth knowing about a place onto one map, organised into layers you can turn on and off. Some layers are permanent fixtures — blue plaques, drinking fountains, live webcams, public services. Others are things happening — this week's exhibitions, what's on, events with a date and a place. Open it and you see what's around you; pick the layers you care about. It's free, and it runs in your browser.
Trupin opens on your area and shows what's nearby. Along the top is a row of layers — heritage, bathing-water quality, exhibitions, food, walking, webcams and more — tap any one to switch it on or off.
Pins come in two kinds. Info pins are permanent things — a blue plaque, a drinking fountain, a live webcam. Event pins are things happening at a time — an exhibition, a local event — and you can filter them by date to see what's on when. You can show or hide each kind independently.
Tap any pin to see its details. Search to jump to a place or a kind of thing — as you type, Trupin suggests tags that match what's on the map. Found something good? Share the view: the layers and location you're looking at travel in the link, so whoever opens it lands on the same map.
Browsing is free and needs no account — just open the map. You only need to sign in if you want to add your own pins to the map (see "Adding to the map" below).
Trupin works in any mobile browser at app.trupin.co.uk, and there's a Trupin app on the App Store for browsing on the go. On mobile, Trupin is for exploring the map — adding and editing pins is done in the browser version on a larger screen.
Trupin's layers come from the organisations that know your area — public bodies and trusted sources. Bathing-water quality from the Environment Agency, blue plaques from English Heritage, drinking fountains from the Greater London Authority, events and facilities from local councils, and more. Each layer is credited to its source. Most are refreshed daily; a few, like webcams and bathing-water status, are genuinely live. We curate what belongs on a map of a place — and we don't track you to build it.
You can add your own pins to Trupin from the browser version at app.trupin.co.uk — sign in, and use the menu to add a pin. Step-by-step help (dropping pins, adding images, events, formatting) lives in the in-app help, in the menu on the map. New pins are published to the map and are subject to moderation. Adding pins is done on the web; the mobile app is for browsing.

If you maintain a local dataset — events, amenities, environmental readings, heritage records — you can put it on the map your area is already using, credited to you and kept current automatically. Get in touch and we'll wire it in.
