Please clarify what you are attempting to achieve.
- If you are trying to register a new Twitter app then you will need to find a unique name to label it on Twitter.
- if you are trying to identify the owner of the existing app with this name, this is not possible for user privacy reasons. If you have lost access to an account or application you can use our support forms https://support.twitter.com/forms to request assistant.
Please do not comment on unrelated threads to request assistance, this is unhelpful.
Thanks.
