If you mean an app that is similar to an app Apple already offers, such as a reminder app, then sure. But please keep in mind that you cannot simply copy Apple's Reminders (or any of their apps) or other apps on the App Store, and tweak it a bit, then publish that.
Per the App Store Submission Guideline:
4.1 Copycats
Come up with your own ideas. We know you have them, so make yours come to life. Don’t simply copy the latest popular app on the App Store, or make some minor changes to another app’s name or UI and pass it off as your own. In addition to risking an intellectual property infringement claim, it makes the App Store harder to navigate and just isn’t fair to your fellow developers.
So simply put, do not copy an existing app with minimal changes, have one or two exclusive features that really make it appealing to users of other reminder apps, for example. Hope this helps.
Best of luck!
