App Store ratings in the countries we track, 4-week average.
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Simple Diary Journal with Lock
No account is required. Your diary entries and photos are stored locally on your device, so you do not need to upload personal writing to a company server or cloud diary service. You can also write offline, making it a good choice for people who want a simple journal they can use privately.
Protect your diary with a passcode lock, add photos to your entries, search past writing by words you used, and customize the app so it feels comfortable to write in every day.

Keep Your Diary Private
This app is designed for people who want to keep their diary personal.
Your diary entries and attached photos are stored locally on your device. You do not need to create an account, sign in, or sync your diary to a cloud service just to start writing.
You can also use the app offline. This makes it useful when you want to write in a private place, while traveling, or whenever you do not want your journal to depend on an internet connection.
Passcode Lock for Extra Privacy
You can protect your diary with a passcode lock.
This helps prevent others from easily opening your journal when they use your phone. It is useful for personal notes, private thoughts, daily reflections, mood records, and memories you do not want others to see.
Write Freely Every Day
Use the app to write about your day, your feelings, ideas, work notes, travel memories, family moments, hobbies, or anything you want to remember.
There is no fixed format. You can write a short note when you only have a minute, or write a longer entry when you want to look back on the day in more detail.
You can also create multiple entries on the same day, so it is easy to separate morning notes, work notes, photos, thoughts, and small moments from different parts of the day.
Add Photos to Your Diary
Each entry can include up to 15 photos.
Add pictures from your device to keep memories together with your writing. This is useful for a photo diary, travel journal, meal record, hobby log, pet diary, family memories, outfits, events, or everyday moments.
Search Your Past Entries
You can search past entries by words or phrases.
For example, you can write words such as #travel, #work, #family, or #idea in your diary and search for them later. This is not a separate tag system, but it can be used like simple hashtag search when you want to find related entries.
Comfortable Writing Settings
Choose from 19 color themes and adjust the writing screen to match your style.
