Enter a sight — the body, the precise UTC time of the mark, your sextant altitude, your height of eye — and Sextant does the rest: almanac lookup, altitude corrections (dip, refraction, semi-diameter, parallax), intercept-method reduction, and an on-screen plotting sheet you can read like the paper original. What's in 1.2.0: • Mac Catalyst — same app, native on Apple silicon Macs. • AR sextant — line up the body in your camera and the device records the altitude (calibrate against a known horizon first). • Chart overlays — import GPX or KML route/waypoint files and they render directly on the plot sheet. • Sky Tonight — table of every body above your horizon right now, plus a "Chart" view showing star positions on a stereographic dome. • GPS-default observer — Sky Tonight, noon-run setup, and the AR HUD all start from your current GPS fix (still optional; the manual DR workflow is unchanged). • Demo voyage — tap "Try a sample voyage" for a 3-day Hawaiian Passage with five Sun sights, two noon runs, three Polaris obs, and three computed fixes. • Localized in French, Spanish, German, and Norwegian Bokmål (body names and nav abbreviations stay in their nautical-standard form). The fundamentals haven't changed: • Sun, Moon, Venus, Mars, Jupiter, Saturn, and 57 Nautical-Almanac stars. • Fully offline forever. The ephemeris is computed from Meeus, VSOP87, and ELP-2000 algorithms — there are no almanac files to update, no annual app refresh. • Sync across iPhone, iPad, Mac, and Apple Watch via your private iCloud database. • Apple Watch companion: one-tap MARK captures the exact moment of a sight, then sync to your phone to finish the entry. • Built on the published Nautical Almanac — every algorithm is graded against JPL Horizons values to arc-minute precision. • No tracking. No advertising. No third-party SDKs. Nothing leaves your iCloud account. Built for navigators who want the dignity of the math, not the seduction of a black box. ## Sextant Pro Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/64/ce/5e/64ce5e41-14f6-5c73-a696-609edc0dd320/03-sight-detail.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/d3/d8/75/d3d87517-4cdb-fa3d-1c7e-9204b33c6832/01-voyage-list.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/dd/35/80/dd3580a1-1aa5-8c47-787c-489e3fcc7624/06-polaris-detail.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/64/bb/9c/64bb9ca5-66d5-1304-f6f4-b2edb83c3bc1/02-sights-tab.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/18/a8/47/18a847d7-86f2-fbb5-48be-d879bf87b9c9/04-sky-tonight-chart.png/1320x2868.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/46/42/b8/4642b87b-c0b4-1573-75d5-21161133ee17/05-noon-run-detail.png/1320x2868.png) ## Sextant Pro Available In - [Austria](https://apptail.io/app/sextant-pro-IhXA/austria) - [Belgium](https://apptail.io/app/sextant-pro-IhXA/belgium) - [Chile](https://apptail.io/app/sextant-pro-IhXA/chile) - [China](https://apptail.io/app/sextant-pro-IhXA/china) - [Czechia](https://apptail.io/app/sextant-pro-IhXA/czechia) - [Germany](https://apptail.io/app/sextant-pro-IhXA/germany) - [Ecuador](https://apptail.io/app/sextant-pro-IhXA/ecuador) - [Egypt](https://apptail.io/app/sextant-pro-IhXA/egypt) - [Spain](https://apptail.io/app/sextant-pro-IhXA/spain) - [France](https://apptail.io/app/sextant-pro-IhXA/france) - [United Kingdom](https://apptail.io/app/sextant-pro-IhXA/united-kingdom) - [Greece](https://apptail.io/app/sextant-pro-IhXA/greece) - [Hong Kong SAR China](https://apptail.io/app/sextant-pro-IhXA/hong-kong) - [Hungary](https://apptail.io/app/sextant-pro-IhXA/hungary) - [Indonesia](https://apptail.io/app/sextant-pro-IhXA/indonesia) - [Israel](https://apptail.io/app/sextant-pro-IhXA/israel) - [India](https://apptail.io/app/sextant-pro-IhXA/india) - [Italy](https://apptail.io/app/sextant-pro-IhXA/italy) - [Mexico](https://apptail.io/app/sextant-pro-IhXA/mexico) - [Nigeria](https://apptail.io/app/sextant-pro-IhXA/nigeria) - [Netherlands](https://apptail.io/app/sextant-pro-IhXA/netherlands) - [Norway](https://apptail.io/app/sextant-pro-IhXA/norway) - [Philippines](https://apptail.io/app/sextant-pro-IhXA/philippines) - [Saudi Arabia](https://apptail.io/app/sextant-pro-IhXA/saudi-arabia) - [Singapore](https://apptail.io/app/sextant-pro-IhXA/singapore) - [Slovakia](https://apptail.io/app/sextant-pro-IhXA/slovakia) - [Thailand](https://apptail.io/app/sextant-pro-IhXA/thailand) - [Ukraine](https://apptail.io/app/sextant-pro-IhXA/ukraine) - [United States](https://apptail.io/app/sextant-pro-IhXA/united-states) - [Vietnam](https://apptail.io/app/sextant-pro-IhXA/vietnam) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
