There isn't a specific list when you write a review for an application, but it's best to stay neutral. For example, don't say something good about it, if the features are not working properly. You need to provide accurate information about the way it works and if it works. You need to test it and watch the features, errors, bugs. Also, don't give vague information if you haven't tested something. Always stay on subject, but avoid making it being too superlative.
