Dudettsky ,

Usually fabulous

Since last update however none of the information is accurate. Keeps telling me that the sun rises at 12 noon and there is no setpoint. Keep saying the moon is 98% full and rising although we are waning and just before half. When I hit reset to current location everything goes black except for the orbits. Best of all, when I hit follow the sky, I get a pop-up telling me that follow the sky only works when I am on earth. 😦


Still the Same!

Great app... wish it wasn’t so expensive.... but I had RedSky when I had it on my “computer” loaded by “floppy disk.” This updated version that allows real-time sky following on a mobile phone is excellent. I really recommend that educators use this app.

Developer Response ,

Hi TARDIS75, thank you very much for the great feedback!

Worth it’s cost.

If all apps were this good I would buy more apps.

Clean UI.

Friendly to beginners.

The devs obviously care.

It is my hope that if you are on the fence, I can nudge you into supporting good apps like this one.

Edit: I forgot to mention the most important part. Dr. Becky recommended this app.

Edit 2: YOU GUYS! The augmented reality is fantastic. This app keeps delivering.
