The Android Market has hit 10 billion downloads. Google is celebrating this milestone by throwing an unusual sale: each day 10 different apps will be put on sale for 10 cents. The offer will run for 10 days. If you love to buy apps, you now have the chance to buy 100 of them for $10.

Although Google's app store has reached 10 billion downloads, that number continues to grow at an almost exponential pace. The company claims they expect a growth of 1 billion apps per month and predicts continued acceleration in the coming months. By comparison, the Apple App Store is estimated to have reached 18 billion downloads this month, 5 billion of which came in the first two years of offering apps. 

While the Android Market continues to catch up to the App Store in a variety of metrics, Google continues to lag behind in revenue. As we reported a couple of weeks ago, Apple rakes in nearly 1200% more in profit than Google through its app market, seemingly the result of Android owners' conservative tendencies toward app purchasing.

Titles listed on on the blog include Minecraft Mobile, Sketchbook mobileAsphalt 6 HD, Color & Draw for Kids, Endomondo Sports Tracker Pro, Fieldrunners HD, Great Little War Game, Paper Camera, Soundhound Infinity & Swiftkey X. Although these deals were posted Tuesday, they still appear to 10 cents this Wednesday afternoon.

The 10 cent sale is being done in cooperation with developers with whom Google has partnered. So far, we don't know what titles will be available in the days to come, but you can check out the Android Market promotional page to see what has made it into the 10 cent bin.
