Description
A fully functional digital astrolabe.Now you too can tell the time with your phone! Take observations of the sun's elevation, and compute the current time in three simple steps. Accurate to about +/- 5 minutes.
And much more.
Navigate by the stars; figure out what time the sun will rise tomorrow morning; and the time of onset of total darkness. And hundreds more useful calculations.
Astrolabes are general-purpose astronomical computers, that can perform over 600 astronomical calculations, most of which can be performed on 2play Astrolabe.
Provides unique insights into how the universe revolves around us.

Could be a lot better It is really bad that it can't open without getting a GPS fix. There could at least be an option for manually entering lat/long or even place names. It is disappointing that it does not appear to give a real-time update. To be honest that is the main thing I would use it for. It does not scale at all well on my phone screen, the labels are all overlapping. There appear to be almost no customisable settings, no zoom, no indication of time and date that I can see. However for a single-use demonstration of how to sight the sun or a star and use that sighting to read the local time, it is pretty effective. Looking forward to a serious upgrade in functionality though...

Nice, but... As others said, it would be advantageous to have a zoom option. You can't use it for much more other than telling the time.

Foolproof Used it as a tool to verify the 'labes I built. Works great.

Zoom? Hi, I use an astrolabe and love the app. Is there a way to zoom in? If so I am not seeing it. The ability to zoom in would greatly improve the app by making it easier to set for stars and easier to read the results. Please consider adding this feature.

Will not work. Keeps telling me to enable GPS even though its already enabled. Sloppy...

What's up with GPS? I'd love to rate this higher but I can't get it to work! It keeps prompting me to enable GPS on my phone in order to start (GPS is already enabled )

This works really well. A zoom function would make it even better.

Nice app! Easy to use and understand. Stable- no crashes or conflicts so far. Cannot open the Preferences. A zoom might be helpful. DROID2.
