Ceven Labs · Aarhus, Denmark
Make the most out of every flight.
Ceven Labs builds tools for people who fly, and for people the flights fly over. Two sides of the same sky, both worth reading.
LayOvr
When you fly, arrive ready. LayOvr plans your sleep, light, and caffeine around your real flights so you land with energy for what actually matters.
OvrHead
When aircraft fly over you, learn something. OvrHead reads every plane over Aarhus and turns weeks of the record into a live picture of European airspace.
Two sides of the same sky.
Flight is the thread. LayOvr is for the flights you take, and gives you back the time and energy jet lag quietly takes away. OvrHead is for the flights that fly over you, and turns them into something you can read. Both are built on the same three principles.
The flight is worth reading.
Every flight already carries a story. The one you take costs you a day on either end if you leave it to chance. The one that passes above you carries a route, a fleet, a weather deviation, a market decision. Both are readable; most people never see them read.
The science is the pitch.
LayOvr runs the two-process sleep model and Phase Response Curves that circadian researchers actually use. OvrHead publishes the raw flight record under every reading, with the query that produced it. No opinion smuggled in, no source hidden.
The signal is yours.
Nothing you do here leaves your device. LayOvr keeps your health data on your iPhone. OvrHead runs the whole flight database in your browser. No accounts, no analytics, no backend that would need protecting.
