Trajectory Study
Read full descriptionHide full description
Trajectory Study is a private driving log for recording the route of a drive and returning to it later. Not only the destination, but the roads taken to get there, the places where you stopped, the photos you kept, and the changing elevation of the road. Each Drive is preserved as a record connected to time and place. During a drive, the priority is simply to record. The route, Events and Photos can be captured as they happen, while Segments and other details can be organized and edited afterwards. Your Drives are collected in the Archive, where you can revisit the route, review individual Segments and Events, view Photos, and examine the elevation profile and elevation gain. Trajectory Study is designed as a local-first tool. Drive data is stored on your device. Trajectory Study does not upload or store your Drive history on developer-controlled servers, and no account is required. Native Backup / Restore lets you create a backup and choose where to keep it using the system document picker. Record the drive. Study the trajectory.

Verdict
The clearest difference is update cadence: Trajectory Study at every 2 weeks against SriLankan Airlines's every 2 months. SriLankan Airlines's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.2). On price, ads and in-app purchases there is nothing between them.
