Excellent option for route, .gpx building and data management. I've been using this app for years and it still beats other apps in my opinion.

Best in class... by a large margin Update 12/25/25 - changing the review to 2 stars. CalTopo's development has focused on features that few want, and ignored bug fixes and small improvements that affect many. After many years as a paid customer I have purchased an OnX subscription.
