Tools are great. The full app is better. Free, no signup, on Google Play.
We built Runplanner because every other route planner had a catch — a signup wall, a tracking pixel, or a pace calculator hidden behind ads. These tools are the same idea on the web: useful, free, no asterisks. If you find a tool you wish existed, tell us and we'll see if we can add it.
