Enjoyed the app for a while. Simple with good options. Recommended to others over the years. However, the last several times I've tried to use it, it is WAY off, for example: telling me the sun is ~15° below sunrise when I'm watching the sunset.... I have GPS, data and wifi on (or off) trying different settings to determine location. Tried all the troubleshooting tips, but it can't figure it out, I guess. Uninstalled because it was unusable (and I'm not techy enough to dig deeper).

We're sorry to see you go after years of support! If the Sun is misplaced, it's usually a time zone or location permission issue. We've tried to make that more obvious in the app. If you ever return, a screenshot of your Diagnostics page sent to skymapdevs@gmail.com helps us investigate.

Interesting app... Major problem is the compass is never accurate. The app will tell you if the internal compass needs calibration. This never works, even at high accuracy, it still is off by 90 degrees, give or take. There should be an actual manual calibration option. Not some silly flip-your-phone-for-twenty-minutes-for-no-measurable-improvement method.

We hear you—waving your phone can feel a bit silly! However, compass accuracy is a hardware limitation of the phone and even a calibrated compass can be inaccurate on some phones. Since you have a consistent offset, try the 'Manual compass offset' we added for you under Settings. More tips: https://stardroid.app

If you just want to find objects in the night sky, and don't need all the bells & whistles (& details) of a more powerful (and storage-hungry) astronomy app, you really can't go wrong with this 10MB wonder. I'm an astronomy nerd w/ a more hardcore app on my laptop, but for my phone, this is perfect. Pity it appears to be abandonare, after 2y w/o an update. But don't let that stop you from trying it.
