Very nice app

With all of the option switching available, one can configure the display nicely. Note that this app's direction was way off. I found it was not the app, but the compass in the surface. To correct this, download Asparion Compass+ from the MS app store and recalibrate.

Time bug

Graphics are ok, and feature set is good enough, but the real time option does not show the current time.

Very nice star chart! Smooth performance. Time bug

Smooth performance on surface! works with point to sky and very easy to use options to enable/disable lots of view options. Nice night mode as well. 5 stars once the time is fixed, it has problems reflecting correct time for me. Its a day ahead it appears. If I hit current time the position of sun is still off

Pain on a tablet

Small 2 x 3 corner of screen with a side view of words, not like the picture.

moon & star name sizes

there should be a separate setting for moon size ... maybe a setting for depict actual or relative moon size (with proper phasing of course). A slider to adjust star name font size would also be a plus.

Really nice interface, almost work perfectly

Two things: it defaults to a Japan location I guess, it should default to the local position if allowed by the user. The compass is off, not sure if it is a limitation in Surface of the program.

Trial version works OK.

Too many constellations on the maps. Works OK but not refined.
