Turn coordinates into your route. DotTrail is a route-file editor by LocationLab for iPhone and iPad. No app account is required. • Import and export GPX, KML, GeoJSON and CSV. • Recognize decimal, DDM and DMS coordinates in mixed text, then preview and create a straight-line route. • Connect points in order; select, drag, rename, reorder and delete them on the map or in the list. • Draw a polygon to preview and remove points inside it. • Generate a zigzag route inside a selected map area with adjustable spacing and direction. • Route Tools: add loops around selected points, use fixed or ranged offsets, and build circular detours. • Smart Organize: shorten a trip, optionally keep the end, return to the start, merge nearby points, or renumber names with a prefix. • Preview the original and adjusted routes with point counts and distance comparisons before applying. • Undo and redo, restore three recent saved versions, and recover deleted routes. • Save and reopen projects, export repeatedly, and back up the original import and history. • Sync with iCloud between devices using the same Apple Account. English and Traditional Chinese follow your system language. Free download with a bottom banner ad; no subscriptions or in-app purchases. Routes use straight lines and do not provide road navigation. Smart sorting uses straight-line distances, does not consider roads or obstacles, and does not guarantee a mathematically shortest route. Smart sorting supports up to 2,000 points; imports support up to 25 MB and 20,000 points. Multiple routes are combined in file order. GPX waypoints take priority over route data. Conversion retains supported fields; other original content remains available in a full project backup.
