Calendar App with Custom Notification Tone

[AC Question]

I really hate Samsung's original ringtones. For event reminder, they're way too short!! I mostly don't notice when an event reminded pops up. Is there any recommendation app which the ringtone can be customized? I've been installed-uninstalled many calendar apps but I have no luck.

I really like calengoo. Lots of customizations, including notification sounds.
