Motif has to be one of the cleanest Icon Packs available on the Play Store to date! Motif is by "Pure Designs" who says the idea behind this series is to inspire creatives for a fresh and inspirational start to their day. The theme is said to work well with Apex, Nova, ADW, and Go Launchers. It should work with other launchers as well, but other launchers have not been tested so that can not be guaranteed. The theme includes over 150 unique icons, and the developer actually has a link to take request for app icons! This will be updated on a regular basis. You can grab this from the source link below for $1.49.
