I mainly use this for customization of my icons. It does the job. When applied, I don't like the fact that my calendar icon stays at the date "31". I like looking at my calendar icon and seeing the correct date. I also wish you could change the colors on your calculator, it shows the app, you just can't change it. For some reason the colors that show up don't align with the colors I have picked for my theme and they are very muted. I'm not sure if this is something that can be looked into.

Decent app depending on what you're into, my only use for the app is the ability to change the icons and color themes using Theme park, otherwise I have no use for any of the other functions. was hoping the Edge lighting would be a bit more in depth, but it's more-so childish and lackluster in it's customizable options. but again. this is dependant on your needs I'm sure it's wonderful for some people. Just feels empty to me.

cool app, ALTHOUGH!, DEVS! When using the lock screen "lock star thing, i put the calendar as one widget then 'world clock below that. Even when I said the location to local city (because I just want a regular clock under my calender) it only ever displays bloody London. I realize it's world clock and not just clock, would be good if I could just do regular clock edit, I see there's clock right hand top corner of calender, but still. world clock only ever shows London, regardles of city's added
