# Frequently asked questions

- How does this clock measure time
It does not measure time in hours or minutes but rather in years, moons, or days. The clock hands turn in clockwise direction just like a normal clock. The only real difference is that unlike seconds and minutes, there is not a whole number of days in a moon or moons in year.

- Can I make my own graphics theme or skin?
Yes, instructions will be published soon. Artists get their name and a clickable link in the app.

- There is no advertising and no in-app purchase. Do you make any money on this?
No, only spending money. To contribute to reducing my losses please consider [sponsoring](https://github.com/sponsors/arnodenhond)

Comments on AstroClock for Android

★★★★★ A Google User · Oct 22, 2012
Awesome Best widget and wallpaper. Live the themes.
★★★★☆ A Google user · Jan 31, 2016
Beautiful This clock is very pretty and unique. I love it! I only rated it four stars because I wish there were more themes. Also, one of the themes loads completely different from what the picture looks like, but still nice. Also, if I try to add a background it freezes the whole app, and I have to reinstall it. But it's a great clock, and I love the notifications for the moon phases! Very useful
★★★★★ A Google User · Aug 17, 2012
Live Folder Check out the Live Folder listing the dates (and times) of upcoming phases for all cycles ordered chronologically. On ICS use the "Live Folder Shortcut" app to view any Live Folder.
★★☆☆☆ A Google user · Oct 19, 2016
Did love it Can't get any of the themes to work but the first one, I changed to a different theme, and it just keeps displaying the first one!
★☆☆☆☆ A Google User · Jul 16, 2014
Sadly no longer works This was the first app I purchased when Android was born years ago, but sadly it no longer works on any of my high resolution displays.
★☆☆☆☆ Stevie · Jan 31, 2010
Does not use GPS or internet location on nexus one and cannot change lat or long
★★☆☆☆ Bill Cole · Mar 10, 2010
More pretty than useful. Need to use stats option to get values. Sun times not consistent with "Sunrise Sunset" app, but I'm not sure which is right.
★☆☆☆☆ A Google User · Jul 6, 2012
This is a great app but with latest update, it stopped working on my G1/Dream phone, it forces closes.
