Want to fully like the app. The notifications saying what unique things are happening in the sky are useful and make the app enjoyable. I would really like it if you could see those unique instances somewhere in the bin. Sometimes I open the app based on a notification and realize that I need to look at it later when the sky is n more visible, but the constellation opportunity is gone if you open the app once. There's no way to see it again later the same night. This is why I gave 3 stars.

I purchased the full version of the Star Tracker for $2.99. And I found that all the ads came back again and don't have the full version no longer , it's telling me that I need to repurchase it again. And it not recognized any credit that is listed. I wanted to know how I can Restore the one that I paid for. I provided a comment as well directly to the App on Google play store. Hope someone will reach out on me.

The stars, chart and the application, it's quite beautiful, especially with the music. I think it could use a little more instruction on finding the particular star cluster, matching the star with the chart & the approximate time as I have found some difficulty in matching Stars with the chart. Most of the planets in May are not available until early morning-the chart indicates that they are available when notified, in reality, they are not But for a free application it's display its top grade
