Navigate in open waters without a GPS. The phone's camera is used to make sightings of the sun, moon, Venus, or Mars. The sighting results are plotted as lines of position with multiple sightings combined into a running fix. Your estimated position is displayed on a lat/lon grid. You can also use your sextant and take advantage of the built-in almanac and plotting tools.

Verdict
The clearest difference is price: Doyle Guides at Free against EZ Sextant's $24.99. Doyle Guides also leads on ratings volume (50 vs 4) and iOS requirement (16.6 vs 26.0). EZ Sextant's advantage is rating (5.0 vs 4.3) and review sentiment (100% vs 60%). On update cadence, ads and device support there is nothing between them.
