This app does all the calculations to reduce a sextant reading to a line of position on the map. All intermediate numbers are shown to check your manual calculations.
• Perpetual nautical almanac
• Calculation of the line of position (azimuth and distance)
• Draws the line of position on the map.
• Star Finder: just point your device to the sky to identify the navigational stars.
• Save your readings, choose what to show on the map.
A sextant is required to make full use of this app.

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
