Clip & Clip

This app stores a text into its own list when you copy a text. To paste a text, open the app, select a text form the list, and paste it where you need.
Also, you can save text that you often use as Favorites, so that you can easily paste them. You can paste them from Favorite in the same manner.
Moreover, you can set the app sync with Evernote, so you will be able to use the app as memo or note by just coping text.
