Do you really have a registered trademark already? If not, you should remove the registered trademark symbol.
The proper way to indicate a claim to mark by usage is to use the "TM" (trademark) or "SM" (service mark) designation which indicates a common-law or state law mark. This is also the proper designation if you have filed an application with the United States Patent and Trademark Office (USPTO) but the mark has not yet been granted registration.
You can only legally use the federal registration symbol "®" after the USPTO actually registers a mark, and not while an application is pending or based on common law rights.
I love the design! It's fantastic. And I can see this app being super-useful. Congrats, I think this one's gonna be a home run!
