Comments on Night Sky Tools - Astronomy for Android

★★★★★ This is such a wonderful app with so many useful tools. I have switched to Apple for my phone and I see this app is not offered with Apple devices. Any chance of it being developed for for this platform. I so love it and will miss it!

★★★★★ Why is it not compatible with my Huawei 10P Lite?

★★★★★ Great app for checking out what's up, selecting standard stars etc. -- would be great if you could add airmass calculations to the sky map, and airmass charts (like jskycalc) would just be incredible. Would definitely pay for a version of the app with pro features like those.

★★☆☆☆ This app was useful but seems to have been hijacked into malware. It's started trying to identify my phone calls.

★★☆☆☆ Started randomly scanning my incoming calls as some alleged caller id feature... Very odd for a astronomy app. Don't trust it anymore, uninstalling.

★★☆☆☆ Do not download this app!! It was amazing until the latest update and it's insanely invasive permissions, now it's a privacy nightmare. And trying to pass the caller ID off as a "feature" is just a joke. It's an invasion of privacy, that's what it is. Do not download this app!! It deserves far less than one star. If I could assign negative stars to an app then this one would receive negative 1000 stars. Do not download this app. You have been warned.
