EZ Diary allows you to create multiple diaries, with unlimited entries in each. Add password protection at both the diary and journal level, customize your theme colors, and (optionally) sync your diary across your devices by signing in with an Ape Apps Account. EZ Diary even allows you to print out your diary to paper for permanent storage.
