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.

Verdict
The clearest difference is in-app purchases: DotTrail at none against 留己看's 3. DotTrail also leads on update cadence (daily vs weekly). 留己看's advantage is ads (none vs shown) and iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
