Is there a shop like Cydia on iOS for Android?

Most apps in the Google Play store have a free version and a paid version. On iOS there is a shop called Cydia, where you can try out most apps for free before you buy them in the App Store. Is there such a store for rooted Androids as well? I know of the store F-Droid for free software > F-Droid is an installable catalogue of FOSS (Free and Open Source Software)
