Some thoughts are for everyone. Some are for no one but you. KeepThoughts is a quiet journal for both. Write a line or a long entry, tag how you felt, and lock the ones meant only for you behind their own passcode. WRITE THE WAY YOU THINK • Start with a title and write as much or as little as you like • Format with simple Markdown: headings, bold, lists and quotes • Add photos from your library or straight from the camera • Pin the one entry that matters most to the top of your list • Star your favourites and filter down to them in a tap TAG A THOUGHT, FIND IT LATER • Mark an entry as a Note, an Idea or a Plan • Or tag how you felt: Happy, Grateful, Calm, Anxious, Sad or Angry • Filter your journal by any tag to see a mood take shape over time • Browse by date in the calendar and open any day you wrote LOCK A THOUGHT, NOT JUST THE APP • Lock individual entries with a passcode used only for locking • A locked entry is encrypted on your device, and its title and text are unreadable until you open it • Locked entries stay locked inside your backups, and open on a new device with the passcode that sealed them • Unlock one for a moment to read or edit it, then let it seal itself again • Separately, you can ask for a passcode or Face ID when the app opens YOUR ENTRIES STAY YOURS • No account, no sign-up, no profile to fill in • Your journal lives on your device • Export everything to a single backup file and protect it with a password • Import that file on another iPhone to move your journal across KEEPTHOUGHTS PREMIUM Pay once, keep it forever.
