With this application, you can organize addresses and phone numbers, foreign language vocabulary, recipes, and more. Additionally, you can choose to set a password that will protect the opening of the directory. Directory Notebook is intentionally simple, without any menus or buttons to save: just like with a real notebook, you write and everything is automatically saved. There is no need to be connected to the internet to access your information; everything is stored in your device's memory. This ensures that your data is always available and, most importantly, remains confidential. When connected to the internet, you can use the voice input function: press the keyboard key representing a microphone to activate it. If this key doesn't appear, go to the configuration settings and enable "Voice Input." With Auto Backup for App enabled, you can retrieve your data during a fresh installation of the application.
