There are many published lists of app review sites with many purporting to have the best on their list. These will vary a lot due to the age of the list, the selection criteria used and the purpose of the list. Some lists are for developers and some are for consumers. Some are for iPhone, others for Android. Companies are always entering or leaving the market, changing names, merging, etc. So if you are looking for app review sites, a good start would be looking for the most recently published sites directed at what you want out of it.
