Quick, accurate, yet fully featured, this is the survey tool that is always in your pocket. Create projects and record and classify features and routes as you pace out the landscape. Points can be recorded in any of three ways: Single points at the press of the button, automatically at regular timed intervals, or as you take a photograph. The project keeps track of all the recorded points and records the Latitude, Longitude, Altitude, and Heading plus the links to any photographs. The project can be saved direct to the iCloud drive or to the photo library. The data is also saved direct to the iCloud drive or sent via email using the universal CSV standard, for easy import into many GIS type systems or similar. Projects are easily managed and edited from the project list and new projects are created by simply giving them a name and pressing 'Start' Existing projects can be loaded and further points can be added. The individual points that make up a project can easily be managed from a list, where they can also be deleted, re-loaded and appended. For more details please visit the support pages.

Verdict
The clearest difference is price: Highlights at Free against GPSnaps's $4.99. Highlights also leads on rating (4.5 vs 1.0) and update cadence (fortnightly vs every 8 months). GPSnaps's advantage is in-app purchases (none vs 3) and review sentiment (67% vs 53%). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Highlights is free to download; GPSnaps costs $4.99 up front. Highlights sells 3 in-app purchases, starting at $4.99 per month. GPSnaps asks for nothing beyond the download.
Highlights holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Highlights has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 53% of Highlights's written reviews are positive against 67% of GPSnaps's, so the app with the better star average is not the one people write more warmly about.
Highlights ships an update fortnightly, GPSnaps every 8 months. The most recent releases landed on October 21, 2026 and October 12, 2026 respectively.
