I am making a app and want to name it as "EVEREST".
But, i found it is used by some other app.
Can any body tell me if it is possible for me to use the name as well?
is it possiable to create a app with a name of "everest"
Not possible.
Unless that developer deletes his app from the App Store, you will not be able to use the name.
Once an app under development has selected a name no one else can use it. Apple has a way of communicating with a particular user who has selected a name and not launched an app to ask them to release the name - I recall an issue surrounding trademarked names - but I do not know how you do that. You can use the name Climbing Everest or Everest1 or maybe Everest!
If the name has been trademarked then names that are a slight variation of Everest (Everest!) may still fall under trademark laws.
I'm not a lawyer but I have trademarked my app name after I consulted with an attorney familiar with that part of the law.
The question as to whether Everest! is a violation of a trademark for an app named Everest presupposes that the developer for an app named Everest trademarked the name - as you chose to do. But a possible trademark violation is not why the OP can't use the name Everest for their App - it's because someone else has claimed that name for an App.
"Everest!" is a different app name than "Everest".
While I am certain that EverestA is different from Everest, I am not certain that Everest. or EveRest or Ev-erest or, for that matter Everest! is different. I do know that the itms code omits characters like "-" from an app name and that is why I wonder about "!".
The OP could just try to reserve the name.
Then we'll all know.
