A few users who create sea route animations told us something simple:

Everything looks great but the distance is in km.

For ocean routes, nautical miles are the standard.

While building TravelAnimator, we kept noticing the same feedback again and again.

Most apps (including ours earlier) draw straight lines between two points when you create a route.

One thing we noticed while building TravelAnimator:
Many travel videos are actually round trips.

Road trips.
Hikes that return to the starting point.
Cycling routes.
Out-and-back journeys.

But creating the return path meant manually rebuilding the same route in reverse. Not ideal.

So we shipped a simple solution.
