A digital journal is still usable a year from now if you do five things in the first week: choose an app you can leave (Day 1), write a short first entry (Day 1), set a handful of tags with one naming rule (Day 2), tie a reminder to something you already do (Day 3), add a photo without bloating the app (Day 5), and export the whole thing to plain text and put the copy somewhere else (Day 7). AI insights, mood graphs and templates can wait, and most of them can wait forever.
In The Art of Journaling, chapter 9, I argue that the tool serves the practice, and that the most feature-rich app is often not the one you will write in consistently. My own journaling was done during executive roles, around business objectives, mostly on paper and later digital, weekly and more often when things were on fire. I have not kept a journal in fifteen years; the sequence below is what I would set up now, given what I know about how apps come and go. Where I quote a feature, it is checked against the vendor's current documentation.
Quick Answer: Day 1: pick an app that exports to plain text or Markdown, works offline, searches every entry, encrypts at rest behind a passcode, and does not trap your photos; then write a 60-word first entry (date and time, one thing you are carrying, one specific moment, the emotion). Day 2: eight tag categories, one naming style. Day 3: a reminder tied to coffee or bedtime. Day 5: one compressed, named photo. Day 7: export, open the file in a text editor, copy it elsewhere, and set a repeating note for the next export.
Definition: Digital journaling is a dated, searchable record of what you noticed, kept in software you can leave without losing the record.
Key Evidence: Day One's own export guide lists Plain Text / Markdown and JSON exports (with a note that photos are not included in the text export), and its encryption FAQ states that end-to-end encryption is on by default for new journals. Obsidian states that it stores notes locally as plain-text Markdown files and works offline. Those are the features the checklist is built on.
Key Takeaways
- Pick the app on export first: TXT or Markdown out, offline use, search across the whole journal, a passcode with encryption at rest, and photos you can get back. Obsidian, Day One and Joplin pass on their current documentation.
- Write the first entry on Day 1, about 60 words: date and time, one thing you are carrying, one moment, the emotion.
- Eight tag categories at most, one naming style, dates as YYYY-MM-DD; merge duplicate tags monthly.
- One reminder, tied to coffee or bedtime; after four dismissals, move it to another time.
- Day 7: export the whole journal, open the file in a text editor, copy it somewhere the app does not control, and put the next export in the calendar. Daily writers export weekly; everyone else monthly.
Day 1: choose an app you can leave, then write 60 words
Apps change their pricing, drop features, or close, and the entries go with them. So the first selection criterion is whether you can get everything out.
Five must-haves
- Exports to TXT or Markdown. A plain-text file opens on any device; a proprietary archive opens only in the app that made it.
- Works offline. If the entry cannot be written on a plane or in a dead spot, the habit breaks on the first travel week.
- Search across all entries. The reason to go digital at all is finding the entry from last March. If search is per-journal or per-month, it is not search.
- Encryption at rest with a passcode. Honest writing needs a lock on it. For the most sensitive entries, The Art of Journaling recommends keeping them on the device only.
- No lock-in on photos. Check that the export includes media or that photos stay in your camera roll. Day One's guide, for instance, says its Plain Text / Markdown export does not include photos; the JSON export can.
Three apps that pass, as of their current documentation: Obsidian (notes are local Markdown files; offline by design; open formats, so no lock-in), Day One (Plain Text / Markdown and JSON exports on iOS and macOS, end-to-end encryption on by default for new journals) and Joplin (open source, end-to-end encryption on every platform, exports to HTML, PDF and a one-file-per-note raw format). Notion, Evernote and OneNote are general note tools and are off the list because their exports are not plain-text-first.
The first entry
Write it the day you install the app, before you touch a setting. Four parts: the date and time, one thing you are carrying, one specific moment from today, and the emotion that came with it. About 60 words. An illustrative entry:
Tue 14 Oct, 9:40 pm. Carrying: the supplier contract I said I would read by Friday and have not opened. Moment: the kitchen at 6, my daughter reading the cereal box aloud in a newsreader voice while I stood there thinking about the contract. Emotion: guilt, mostly, with some relief that she did not notice.
The first prompt I was ever given came from a teacher at school, "What I learned today ..." as the opening line of an entry, and it still works as a first line if the four-part format feels like a form.
Day 2: set the tags
Eight tag categories cover almost everything a personal journal holds:
| Tag category | Example tags |
|---|---|
| Time | #Q1, #Winter |
| Activity | #Meetings, #Exercise |
| Emotion | #Anxious, #Calm |
| Subject | #Sleep, #Family |
| Project | #Essays, #Painting |
| Location | #Home, #Cafe |
| Event | #Birthday, #DoctorVisit |
| Source | #BookTitle, #PersonName |
Naming rules matter more than the categories, because inconsistent tags are the same as no tags:
- Pick one style (singular or plural, upper or lower case) and keep it.
- Spell tags out in full: Work. An abbreviation such as W will mean nothing in a year.
- Keep tags short: Fitness. A tag like PhysicalHealthAndFitnessActivities will never be typed twice.
- Do not keep synonyms: Work, Job and Employment collapse into Work.
- Use CamelCase or underscores for multi-word tags, such as MorningRoutine or Work_LifeBalance.
- Write dates as YYYY-MM-DD so they sort correctly.
- Avoid special characters.
Hierarchical tags such as Work/Projects keep related entries together without multiplying top-level tags. Merge duplicates monthly, delete unused tags quarterly, and reread the whole list twice a year. Tag for the search you will actually run: mine was a year-end review, on a calendar-year, fiscal-year or mid-year cycle, so the only tags that would have earned their keep were the ones that grouped a year's entries by objective. Meeting notes, board preparation and conversations never went into my journal; those lived in minutes and task lists, and the journal was for thinking. That is a tagging rule as well: tag what you will think about again, and leave the record-keeping to the tools built for it.
Day 3: set the reminder
A reminder works when it is tied to a trigger you already have. Pick one:
- Visual: the journal app on the home screen, first row.
- Time-based: one recurring alert at the time you chose on Day 1.
- Action-based: pair the entry with coffee or with plugging the phone in at night.
- Environmental: leave the app open on the device you already use at that hour.
One reminder. If you dismiss it four days running, move it to another time.
Day 5: add the first photo
Choose the everyday shot; the photo that holds the mood of a moment serves an entry better than a polished one. One rule: compress it before it goes in (any image-compression tool will do) and name it the way you tag entries, so a dinner picture saved as FamilyDinner_Jul.jpg and tagged Family and Food is findable in a year. Photos are where lock-in hides, which is why the Day 7 export check includes them.
Day 7: export it and put the copy somewhere else
The 3-2-1 rule is the whole backup plan: three copies of the journal, on two kinds of storage, with one copy somewhere other than your home. For most people that means the app's own data, an export on your computer or an external drive, and a copy in a cloud folder. Lock the copies the way you lock the app; our guide to digital journal privacy covers that.
Which format
- TXT or Markdown: opens anywhere; the copy you keep for the long term.
- JSON: the app's own re-import format, and often the only export that carries photos; keep it as the second copy.
- PDF: fixes the layout; good for reading, useless for re-importing.
The ten-minute export test
- Export the whole journal as plain text or Markdown (and as JSON if the app offers it).
- Open the text file in a plain text editor such as TextEdit or Notepad.
- Confirm the dates and the entry text are readable and in order. If the photos matter, open the JSON or media folder and confirm they are there.
- Copy the export to a second location: a different device, a drive, or a cloud folder that the app does not control.
- Put a repeating note in your calendar for the next export.
| If you write | Export |
|---|---|
| Daily | Weekly |
| Weekly or less | Monthly |
To restore: find the most recent full copy, import it into the app (or simply open the text file), skim for gaps, and if a file looks damaged, go back to the copy in the other location. I no longer have my own journals; I discarded them when I retired and downsized, deliberately, and I do not regret it. That is the point of the export: whether the record survives should be your decision.
When this setup does not work
- You never search back. Skip tags entirely. Keep the date in the first line and nothing else; the search box finds words without help.
- Photos dominate. You are keeping a photo log, which is fine, but use the camera roll's own dates and captions and stop paying for journal storage.
- The app is the obstacle. Dictate into your phone's voice notes and paste the transcripts into the journal once a week. The record matters more than the medium, and The Art of Journaling makes the same case for a hybrid of paper and digital.
The mistake that outlasts the first week
Building a system you have to maintain. An over-built setup eats the writing time in tweaking, buries last week's entry under categories, and becomes the reason you stop. Keep a handful of broad tags, format entries the same way each time, and clear out anything that is gathering dust at the twice-yearly tag review. The other mistake, depending on one app, is handled on Day 1 and Day 7; if you skipped the export test, go back and do it.
Why Digital Journaling Matters
The reason to keep a journal in software is search. A year of dated entries becomes a record you can query: every entry tagged Anxious, every mention of one project, every Sunday evening. The setup above exists to keep that advantage: consistent tags so the search returns something, and an export that keeps the record yours when the app changes hands. A digital journal with no export is a rented record; the Day 7 test makes it owned.
