MYDETAR is a free iPhone utility tool developed by Thang Dam Thanh. It serves as a memorandum application that allows users to capture and organize their daily notes using sticky notes. The main features include adding information, selecting topics, setting completion times, and easy retrieval of notes for quick reference.

Users can simply click the button on the homepage to start adding information, choose a topic, set a time for completion, and save the note. The notes can be accessed anytime for review or editing, providing a convenient way to keep track of important details in daily life without the need for physical sticky notes.

MYDETAR emphasizes user privacy by ensuring that no information is collected, with all data stored securely within the app's sandbox. For any feedback or suggestions, users can reach out by leaving a message in the App Store for the developer's prompt response.
