The App Store is a constantly-changing place, with new apps joining the catalog, while others adjust their prices to encourage some new sales. App Deals for iOS aims to point you in the direction of apps for your iPhone or iPad that have been reduced in price, making them an essential purchase, or in some cases, even free. Highlights from today's list include sales on Sesame Street's The Monster at the End of This Book...starring Grover!, Avengers Origins: Assemble!, and budget tool Budgetty.

As with all deal-related posts, the items listed are correct at the time of publication, but may change without warning at a later time. Also, some deals may only be available in certain territories, and may stay at full price in some areas. Bottom line: check the price before purchasing. The deals post will be updated about 9PM ET every weeknight, with the dead deals removed, and more added. The newly listed apps will be at the top of each category.
