Good the app versioning. This is main reason I use it! The app DB is one of the most completed I know as app market. It's growing but there are some lacks Play store don't have. It's better star rating number is visible even in search results instead of the only graph stars. Add the possibility to get info about developer (address, email, website, ecc.) in some way. it can be pretty nice to have app MD5/SHA in app description. Comments and ratings apps are possible even if you didn't install them. Now it's useful in that case you want notice fake apps, clones or malware. But it will be better close this feature for stars rating (only users get app at present or past), leave open to all users for comments and add another field to set clone/fake/malware app as in Aptoide. It's no possible to fix/correct own comments after they posted. Trying to post smileys it crashes. I would like an implementation of apps bookmarks, or something similar, in order to take a look later avoiding to remember the app name or search terms. It can useful if you consider that app interesting for a future install but at present for some reason (not enough space, comments said was good but now is bugged, etc.) better with sort options. It's growing fast, I hope to put 5 stars for the 2nd or 3rd version by now. :)
