CAR-TER for iPhone & iPad
Turn your iPhone
into a dashboard.
See live data. Control a project. Keep what matters in view, with an interface you can make your own.
Free to download. Optional in-app purchases.
How CAR-TER works
A screen. A source.
Something you can do.
Start with a layout someone has made, or build your own. Here’s the idea in three small steps.
1 of 3
A layout puts useful controls together.
A reading, a chart, a switch: each is a control. Arrange them into a layout, and use tabs when you need another view.
Practice scene only. No device is connected.
This desk layout has a temperature reading and a light switch.

A layout
A reading, a chart, a switch: each is a control. Arrange them into a layout, and use tabs when you need another view.
A source
A reading can come from a public API, a phone sensor, or a service you connect. A template can already have this connection set up.
An action
The service handles the request and reports what happened. A tap is a request—not proof that a device changed. Read-only layouts simply let you explore their data.

You don’t need to build
your first layout.
A layout is a screen of readings and controls. Pick a public-data template and it connects for you—no code, API key, or local server to set up.
See the electricity mix
Follow carbon intensity in Great Britain, then turn a reading over to understand it.
02Look closer at a river
Find monitoring stations on a map and compare the station details behind each point.
03Browse a public art collection
Swipe through works of art, with their titles, context, and source kept alongside.
Internet required. Each template explains its source, timing, and limitations.
A little room to explore
More than a picture
of your data.
Touch the thing you want to understand.
Inspect a chart, move around a map, or flip a card for context. A useful view lets you ask the next question.
Keep the view. Change the arrangement.
Start from a template and make a copy when you’re ready to edit. Give the most important reading more space; move the details to another tab.
Connect your own project, when you’re ready.
Buttons, sliders, and other controls can talk to a service you set up. This is the building side of CAR-TER—not a requirement for trying the public-data collection.
