Like Google and Apple’s stores, PreApps lets developers post their apps, which are split into categories, Top Apps, and so on. Each app gets its own page with a description, pricing, expiration (or release) date, screenshots, social sharing, videos, comments and suggestions. Developers can even post polls to ask their users if they like certain tweaks or updates.
