Caelus Duotone Icon Pack

Caelus Duotone icon pack is a set of custom colorful linear icons with semi-transparent fill (duotone style) for your homescreen and app drawer. It can be applied on almost any custom launcher (Nova launcher, Lawnchair, Niagara, etc.) and some default launchers like the Samsung OneUI launcher (via Theme Park app), OnePlus launcher, Oppo’s Color OS, Nothing launcher, etc.

Why do you need a custom icon pack?
Unified icons make your homescreen and app drawer much prettier, and since we all use our phones a few hours per day, it will significantly improve your experience.

What do you get from Caelus Duotone?
Caelus Duotone icon pack has 4,363 icons, 20 custom wallpapers, and 6 KWGT widgets, so it’s all you need to personalize your phone how you like it. For the price of one app, you get content from three different apps. Caelus Duotone icons are linear with semi-transparent details, and the color palette is vibrant, so it goes well with dark wallpapers. Caelus Duotone icon pack is made on a 24x24 px grid with 1 px line thickness, with special attention to size for every icon, so you don't have to worry about the size or line thickness consistency. *To apply KWGT widgets, you need KWGT and KWGT Pro apps.

What if I don’t like the icons after I buy them, or there are a lot of missing icons for the apps I have installed on my phone?
Don’t worry; we offer a 100% refund for the first 24h from when you purchase our pack. No questions asked! But, if you are willing to wait a bit, we update our app every two weeks, so there will be many more apps covered in the future, possibly the ones currently missing too. And if you don’t want to wait and you like our pack, we also offer Premium icon requests which are added in the next release from the moment you send it to us.

How to send an icon request for the Caelus Duotone icon pack?
Open our app and click on the Request card. Check all icons you want to be themed and send requests by pressing the Floating Send button. You will get a share screen with options on how to share requests, and you need to choose Gmail (some other mail clients like Spark, etc., have problems attaching the zip file, which is the most important part of the email). When sending an email, DO NOT delete generated zip file or change the Subject and text in the body of the email – if you do that, your request will become unusable!
