ExpiNotes - Notes with due date

ExpiNotes is a note collector where each note has an expiration date. A timer indicates the remaining time and you can see the history of date changes.
Each note can contain different types of attachments, such as to-do lists (where you can track the time spent and see the total for each task), photo galleries, videos, audio, PDF documents, and hand-drawn notes.
Note attachments can be shared as a single pdf file.
