My Super Secret Diary Notes is a private diary and journal app for iPhone and iPad with a lock. Write daily diary entries, pick the date on a calendar, add photos and emoticons, choose from colorful diary paper designs, and lock the app with a PIN code, pattern or Touch ID so your entries stay private. WHAT YOU CAN DO • Diary with a lock: protect the app with a PIN code, a pattern or Touch ID. • Daily journal entries: write about your day, your thoughts or a memory, and give each entry a title. • Calendar view: choose the exact day something happened, or set a start and end date for memories that span several days, like a trip. • Photo journal: attach photos from your library or take a new one right in the app. • Emoticons: add cute emoticons to show how a day felt. • Custom diary pages: choose colorful paper designs, fonts and text colors. • Search: find any entry quickly by searching your diary. • List view: browse all your entries in one place. • iCloud sync: your diary is backed up to iCloud and available on your iPhone and iPad. • Share: send a single memory to friends or social apps when you choose to. HOW IT WORKS 1. Set a PIN code, pattern or Touch ID lock. 2. Pick a day on the calendar and write your entry. 3. Add a title, photos and emoticons, and choose a page design. 4. Find old entries later in the calendar, the list or with search. WHO IT'S FOR • Anyone who wants a secret diary on their phone that others can't open. • People who keep a daily journal and like to pick the date for each entry. • Travelers who want a photo journal of trips with start and end dates. • Anyone who prefers a cute, colorful diary over a plain notes app. • People looking for a private place for thoughts, memories and personal notes.
