What’s New

Version 3.5.9

- new character controller (if you run into steep cliffs, you will stop).This will also fix the bug with the terrain moving underneath you
- devices with high RAM will have better terrain colliders, so you should not see the character going into the ground
- added new beaming down animation
- can jump (affected by gravity)
- can swim

Close up look at distant stars

One caveat: the app only lets you view a 10-parsec cube at a time; no giant overview to give a clear idea of how far from the sun the area you're looking at is.
However, this is only the second 3D map I've found of our corner of the galaxy that's not stuck centered on the sun! If you'd like a closer view of the area around a particular star, from any angle (what do the Pleiades look like from the back?), this is excellent. Selecting any star gives some basic information: other names, type, magnitude, temperature, a diagram comparing its size to the sun, and a map showing its position in the night sky. There's also a Wikipedia link, though some star pages don't exist yet. Ads generally stay out of the way at the top of the screen, though sometimes they get in way of the back button on star pages (just rotate your phone). Search function hasn't failed to find the stars I'm interested in, but I don't know enough to look for anything really obscure, so I don't know how thorough it is. Very pleased with the app overall!

Thanks for the great review!
I've split the map into 10-parsec cubes so that it works on older models with no significant lag. It is possible to view more than that, I was thinking of adding a "zoom out" feature that shows the adjacent sectors, so instead of viewing a 10 parsec cubes, you will be viewing 30 parsec cubes. I will have to test how much more can be zoomed.

But my first major update to this app will be a highlights section with a list of famous stars, weird stars, multiple star systems.

Explore the Stellar Neighborhood

I’ve greatly enjoyed using this app to traipse across the local area of the galaxy and see where stars are near each other in 3D space. The ads in the free version are unobtrusive and I’m considering upgrading to the full version just because I like enjoy it so much, even though the free version fulfills my needs without issue. The 10-parsec sectors would be perfect for making a map in a sci-fi roleplaying game.

One feature I would like to see, however, is a setting to change from xyz equatorial coordinates to uvw galactic coordinates so I could know whether I was getting closer to the galactic core or farther away, above or below the galactic plane, or in the direction of spin without having to do calculations in my head. Maybe an option to rotate the +Z into the vertical position instead of the +Y too, since I instinctively associate the North star with “up” when working in equatorial coordinates.

I hope you like this new version, I've completely redesigned the app, and new planets are added daily without needing an update (if new ones have been confirmed). Thanks for the review!

I really liked this app, but the last 2 updates have completely broken it. The background has changed to white instead of black, I can’t see the stars anymore. It’s effectively unusable. Really hoping it gets fixed soon

EDIT 1/3/22: The white background has been fixed, and this app is now back and better than ever! So glad to see it working again - 5 stars! This is the best 3D star map program I’ve been able to find anywhere, which is why I was so bummed out when it turned into a blank white screen. It looks great again now!

Should be fixed now in 2.4.14, sorry!
