MyJournal

Keep a journal nearby to reflect on your day to day. Record and remember the good times, find peace of mind for the bad. A journal lets you put distance between you and your thoughts and emotions so you can see and think more clearly. MyJournal lets you keep many journals in your pocket, ready to write whenever you are. Keep one for your achievements, practice gratitude in another, write down goings-on in a third.

This app makes used of Auto Backup if you have it enabled, so in case you ever lose your phone, you won't lose your memories. Each journal can be locked with a simple passcode to prevent unwanted access to that journal. This app includes no ads, and requests the minimum permissions needed to save your journal entries.
