When we published our roundup of iMessage apps and sticker packs yesterday, we had to leave out one of our favorite sticker packs because it hadn’t cleared App Review yet. Fortunately, Sticker Pals from Impending was approved last night.

Sticker Pals, which features illustrations from David Lanham, is the single most ambitious sticker pack I’ve tested with hundreds of stickers divided into categories accessible from buttons along the top row of the sticker viewer. The first four buttons access animated character sets. The other two buttons are a combination of static and animated ’playsets,’ which include things like hats, beards, googly eyes, and food. I’ve had a lot of fun with these stickers, especially when combined with other stickers.

Sticker Pals also has a store where you can spend coins to collect new stickers or send sticker gifts to friends. The coins and gifts are replenished periodically throughout the day at no charge giving you a reason to return to Sticker Pals over and over, collecting new stickers each time. You can also purchase additional character sets and playsets as In-App Purchases; currently Sticker Pals offers one of each.

Sticker Pals, with its standard set of stickers, is available for as a free download from the iMessage App Store. Additional character packs are $1.99 and new playsets are $0.99.
