Hi,
I created new app and submitted but the answer from Apple is:
We noticed that your app provides the same feature set as other apps submitted to the App Store; it simply varies in content or language, which is considered a form of spam.
I coded and designed it by myself. There may be similar apps on App Store doing the similar job but that shouldn't make my app a spam! My algorithm is different and my UI is better. Why I can't compete with other apps? No sense.
