Firstext is a simple text editor application. I named it "First" + "Text" = "Firstext" with the aim of making it the "first step" in all kinds of text creation. Firstext has the following features. ・Start typing as soon as the application is launched. ・The text you type is automatically saved and can be restored at any time. ・Ability to freely share text to other apps by creating and adding share actions to suit your needs. There is no functionality for managing multiple texts or notes, decorating text, or inserting photos. *Before removing the limitation by in-app purchase, the number of shared actions is limited to 10, and the number of saved history is limited to 20. Please understand. After confirming the usability of the application, you can use it without restrictions by making an in-app purchase.

This issue can be avoided by updating to iOS16.1 or later and making the following settings from the Settings app.  (1) Select "Firstext" in the Settings app and select "Paste from Other Apps".  (2) Change the setting to "Allow".  *Notification about pasting will appear even after changing to "Allow". Due to the limitation of iOS, you cannot turn off this notification.
