About this app

Spare Diary โ€” Writing in your spare moments completes your day.

Your diary is saved only on your phone. It is not uploaded to a server, and you do not need to create an account.

How did Park Ji-won write the *Jehol Diary*?

During his journey to the Qing Dynasty, he recorded what he saw and felt on the spotโ€”on horseback, in lodgings, in markets. Thanks to this, the *Jehol Diary* captivates readers with its vivid sense of immediacy even 200 years later.

If he had waited until he returned from his trip to write it all at once, would such a vivid record have remained?

Our daily lives are no different. Sit down in the evening and reflect on your day. The taste of the coffee you drank in the morning, the conversations you had at lunch, the sunset you saw on your way home from workโ€”most of these memories have faded into hazy blurs.

However, things change if you write just one line at that moment. Short notes gather to form a daily diary, and as those days accumulate, your own *Jehol Diary* is completed. When you open the "View Daily" feature in the evening, you can experience the joy of seeing the short writings you jotted down in your spare moments come together to form one long story.

Spare-by-Spare Diary โ€” Writing in your spare moments completes your day. I have been writing a diary this way for over 10 years. It doesn't have to be grand, and it's okay if you don't write every day. Just writing in your spare moments is enough.

I created this app by capturing that experience exactly as it is. The developer uses it personally every day to identify inconveniences and continuously improves it.

Key Features

**Recording in Your Spare Moments**

Before you forget, take notes on this very moment in your spare time and save photos (up to 2). You can take photos directly with the camera or select from your album. Press the microphone button to speakโ€”what you say becomes text. You can freely change the date and time, allowing you to record past moments as well. Touching a photo allows you to view it in full screen, and you can save it directly to your gallery. If desired, you can enable "Things Eaten" and "Tags" in the settings to break down your records into smaller segments.

**Household Account Book**

You can record the money spent at that moment while writing your diary. If you write down the category (e.g., Food, Transportation, Shopping) along with the item name and amount, the category you've already entered will auto-complete, speeding up your next input. Today's total and the total from the 1st of this month to today are visible at a glance on the calendar screen, and opening "Details" allows you to switch between date and category to view all items. Tapping an item takes you directly to the corresponding entry. It also shows whether you spent more or less compared to the same period last month, allowing you to quickly check your spending habits for the month. Try organizing your expenses easily with your diary, without the need for a separate budgeting app.

View Daily

Gather your diary entries written in your spare time onto a single screen to complete the story of your day. Try adding a title that summarizes your day in a single phrase (the phrase you wrote is also displayed on the corresponding date in the calendar). You can also edit each memo immediately by tapping it. Entries with photos can be turned into sentimental cards with an instant photo feel that you can share on Instagram, etc. (The diary content is automatically copied, so you just need to paste it into the caption).

Building a Recording Habit

Writing consistently is the hardest part, isn't it? When you write your first diary entry, you can start the '3-Day Challenge,' and a gentle notification every evening helps you maintain the habit (you can turn it off or change the time in Settings). The calendar displays how many consecutive days you have written and how many days you have recorded so far, allowing you to experience both the fun of continuing and the sense of accomplishment as your entries grow.

Photo of the Day and Photos of the Week

Leave a photo that symbolizes your day. If you tap 'Set as Photo of the Day' on a photo attached to your diary, it will be set immediately, and a week's worth of photos will accumulate in 'Photos of the Week' below the weekly calendar. You can also fill in the blanks on the spot by tapping the + button. The collected week can be saved and shared as a single photo spread with an aspect ratio ideal for Instagram, and if you have two or more photos, you can create a vertical video (time-lapse) right away. You can select a specific period to group them together for a longer duration using 'Create Time-lapse with Different Periods,' and you can also create or rewatch time-lapses from the previous month or week directly on the calendar.

Word Cloud

Meet the word cloud created by your diary. Words that appear frequently in your diary are highlighted in size, allowing you to look back at what you filled your days over the past week, month, or three months at a glance. You can select the time period from 1 week, 1 month, 3 months, or all, or set your own start and end dates. When viewing past months or weeks on the calendar, a word cloud for that period also appears. Tapping a word immediately finds the diary entry containing it, and you can also save it as an image to share. All word analysis takes place within your phone, ensuring your diary entries do not leave your device.

Calendar

You can check the dates you wrote a diary at a glance. In the monthly calendar, you can preview the entries and scheduled notifications for each date, allowing you to see how the month has passed at a glance without having to open each page individually. The date you wrote a diary and today are clearly marked; tapping a date displays the entry for that day below, and tapping it again takes you directly to the "View All" section for that day. You can switch between Monthly, Weekly, List, and Photo views. In List view, you can collect only the days you wrote a diary in reverse chronological order, making it easy for even infrequent writers to find their records. In Photo View, you can view your saved photos organized by date and quickly skip to your desired time using the navigation bar. In Weekly View, "Message of the Day," scheduled notifications, and thumbnails of today's photos are displayed together, and you can add or change photos immediately by tapping the photo slot. If you keep a household budget, today's total and this month's cumulative total are displayed right below the calendar.

Weekly Review

Every Monday, you look back on the past week on a single screen. It gathers your diary entries, scheduled appointments, and expenses for the week at a glance, and also shows you how much things have changed compared to the previous week. You can also continue writing today's diary right there. You can also compile the "Photos of the Day" from that week into a time-lapse video to save or share. This small habit of organizing your week makes the next week clearer.

Notifications

"Appointment at 11 AM tomorrow," "Meeting next Tuesday"โ€”write a short one-line message to your future self and set a time to receive a push notification at that moment. You can repeat daily, weekly, monthly, or yearly, and set an end date or an unlimited duration. Missed notifications are grouped together when you open the app, allowing you to organize them by opening them one by one.

Search

"What did I eat back then?", "When was that appointment?" โ€” Enter a word you remember to find related diary entries immediately. Searched words are highlighted like a highlighter in the results for easy viewing, and the app quickly displays the past year first, followed by older records. You can also filter your records to view only what you want using "Food Only / Tags Only / Household Account Only" filters.

Backup and Restore

Keep your precious diary safe. You can select a specific period to export as a Word file or back up your entire data. Even if you change phones or reinstall the app, you can easily restore your data using the backup file. Save it wherever you prefer, such as Google Drive or email.

Save Daily Diary Instantly

Save just that day's diary directly from the calendar as a Word file, or select a specific period to export together. Store it conveniently in Google Drive.

D-Day

Check at a glance how many days are left until your important day. If you register important dates such as trips, exams, or anniversaries, a countdown like "Travel D-30" will appear every time you write a diary entry. You can register up to two entries.

App Lock

Keep your stories you don't want anyone to see safe in Tteumteum Diary. It is protected by a password, and on iOS, you can also use Face ID. Even if the app locks while you are writing or editing, the previous state is preserved once you unlock it.

Use with peace of mind

We do not collect any personal information, and all diary entries are stored only on your device. No separate registration or login is required. You can also check your storage space in Settings.

Start the habit of writing diary entries in your spare time by installing Tteumteum Diary and starting today.
