About this app

Simple Diary is a private diary app for writing daily notes, saving memories, and keeping personal thoughts on your device.

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.

You can change the font size, line spacing, and text appearance so your diary is easier to read and more comfortable to write in.

Reminders for a Writing Habit

Set reminder notifications when you want to make diary writing part of your daily routine.

A small reminder can help you write down the day’s thoughts, memories, and feelings before you forget them.

A Simple Private Journal

This app focuses on simple writing, local storage, offline use, photo entries, search, reminders, customization, and passcode protection.

Use it as a private diary, daily journal, photo diary, mood note, idea notebook, travel journal, or personal record.

Start keeping your thoughts and memories in a simple diary that stays on your device.

Ratings and reviews

I like the simplicity of the app. I am able to write my thoughts and ideas down. It's cool that you can add a picture from your photos to your ideas. I like that it is simple so my focus can be more geared towards my thoughts. It also has a calendar approach and list view of the journal entries. The app is easy to use. It's a cool 😎 app if you don't need a bunch of bells and whistles. ;-) Thanks!

Clean simple app. Wish the save button weren't so small and difficult to reach at the top of the screen instead of somewhere near the bottom like the pencil button on the home page. It also doesn't automatically send you to the home page after saving, requiring you to manually go back.

I needed something minimalist, so I could focus. Think it, note it, do it. Any extra frills would just get in the way. Voice notes work great in a bunch of foreign languages too. if you need that.
