Very nice app with lots of features if you’re big into satellites. This app has lots of potential. It’s slick and it looks really sharp. Can’t wait to see it grow
Wait, wait, wait…

For every one minute of up time, 40 or more seconds is ads or waiting to load something. Tried Amateur Radio section but it is basically non functional. Tells me to set QTH, done at front screen, but none of the buttons are functional to set or use any feature. Certainly will not consider paying money if I can’t at the least try it as advertised.
Developer Response
Thank you for your feedback! We identified the issue where the location wasn’t saving properly on first launch (which affected QTH detection), and it has now been fully resolved, and the ads have been significantly reduced.Fixed in the latest update:✓ Location now saves instantly - no restart required✓ Clear and accurate status indicators✓ Improved guidance and help instructions✓ Amateur Radio features initialize immediatelyPlease update to the latest version and try again. Your report helped us fix this for everyone. Thank you for helping us improve!
- AR Sky Overlay: See stars, constellations, and deep-sky objects overlaid on your camera view. Tap any object to identify it instantly.
