Cosmos, free to explore
The view extends from nearby space through the planets and stars to the wider universe. Zooming into a constellation separates its stars by their actual distances.
Strata
Zoomable maps of space and history
The bigger picture is only a zoom away.
A list tells you what exists. A map lets you see how things relate. Strata turns space, history and other subjects into worlds you can explore at their own scale.
Free to download. Optional in-app purchases.
A small first step
Start here. See how it feels.
Download Strata and start with Cosmos, the free map from nearby space to the edge of the observable universe.
From download to doing
Make it yours in three steps.
Open Cosmos
Begin with the free map. Start near the space station and planets, then explore stars, constellations and the wider universe.
Change the scale
Zoom to move between the detail and the whole picture. Tap an object to see what it is, or search for something you want to find.
Compare what you find
Tap two things to measure the gap. Turn lines on and off or use the cross-section to focus on the relationships you want to explore.
A closer look
What you can do with Strata.
History in parallel
The optional History pack places civilisations, ideas and events on parallel coloured lines. Explore what was happening in different places at the same moment.
One lens, more subjects
Additional packs apply the same zoomable map idea to life, minerals and other subjects. Choose an individual pack or the Complete unlock when you want more to explore.
