I have been able to rename my apps using deepnaming with no issues at all! It does not feel like it is just spitting out random names that don't make sense but rather ones which are more appropriate for what we need them too be named after. The pricing model was also very reasonable compared other similar services in this space (such as Namely). Nothing really - if anything they could improve upon how quickly an update goes through from release/version number change etc? But otherwise great product overall!! We use Naminator when releasing new versions or updating existing applications so having one place where those changes happen makes life easier than doing multiple releases across different platforms ourselves manually via github commits each time.
