Dec, 11, 2015 - Navigator 2.5 released

Now for iphone and ipad ( same app and features in all devices )

This version uses the phone sensors do auto-orient the star chart and allows capturing the altitude of objects directly with the phone, even without a sextant.


This version can be used with an iSextant, if you build one..

Check the iSextant DYI sextant project


Another addition to this version is the use of world maps in both situation charts. Charts can also be manipulated with standard gestures (pinch and pan to zoom the chart)

GSHHS low resolution charts used (note: not navigation grade charts)
