Apple Journal vs MoodKit (iOS 27): Diary or Mood Data?

Apple’s Journal app gets its most useful update yet in iOS 27, which lands on September 14: streaks you can switch between daily and weekly, iCloud sync status, bigger attachment limits, timestamps on entries, prompts generated from what you’ve written, and edge-to-edge photos, per 9to5Mac’s rundown. It’s free, it’s private, and it now runs on iPhone, iPad, and Mac.

So here’s the fair question for anyone paying for a mood tracker: does a free Apple app that logs your State of Mind make the paid one redundant? Mostly no, but the reasons are specific, and there’s a version of this where you use both. (Disclosure: we build MoodKit, so read the verdict with that in mind. Facts checked September 2026; feature sets drift, so re-check before you decide.)

What Journal is for

Journal is a diary with excellent raw material. It suggests moments from your day (photos, workouts, places, music) and asks you to write about them. The iOS 27 prompts go a step further by reacting to what you’ve already written. Entries are end-to-end encrypted in iCloud, and there’s no account beyond your Apple ID.

Since iOS 18 it can also log a State of Mind entry inside a journal entry: drag a slider from very unpleasant to very pleasant, pick the words that fit, pick what’s having the biggest impact. That entry lands in the Health app, where its history lives.

For reflective writing, with photos, at zero cost, Journal is now the obvious default on iPhone. We wouldn’t argue with anyone who uses it for exactly that.

Where Journal stops

Journal collects, and that’s about where it ends.

• Analysis lives elsewhere, and it’s thin. The new Insights tab is about streaks and entry stats. Mood history is in Health, where State of Mind gets charts and simple side-by-side views with sleep and exercise. We’ve covered what State of Mind can and can’t tell you; the short version is that it shows you the shape of your moods, not their causes.
• No ranking of what drives you. Nothing in Journal or Health will tell you that time outdoors lifts your score by half a point and late nights cost you a full one. You can log a hundred entries and still be guessing.
• No experiments. “Does the morning walk actually help?” is a question you answer by reading back through entries and squinting.
• Writing is the unit. A journal entry is a paragraph. Some days you don’t have a paragraph in you, and on those days the log goes quiet, which are usually the days that mattered.

Use both: write in Journal, measure in MoodKit

The two apps aren’t really competing for the same minute of your day. Journal wants the story; MoodKit wants the number and the tags. The pairing that works:

1. Check in with MoodKit through the day, fifteen seconds at a time. Turn on Apple Health so sleep, exercise, and steps rank alongside your tags, and so each check-in is saved to Health as a State of Mind entry (iOS 18 and later). Your Health mood chart stays complete without double logging.
2. Write in Journal when there’s something to write, with the photos.
3. Once a month, read MoodKit’s leaderboard and Weekly Rhythms next to Journal’s entries. The numbers tell you what moved; the entries usually tell you why.

The Apple Health setup guide covers the toggle, and it’s one toggle.

Which to open first

• You want to remember your life, with pictures: Journal, and it’s free. Stop reading.
• You want to know what’s driving your mood: MoodKit, because that question needs numbers and Journal doesn’t produce them.
• You want both: the pairing above. Journal for the paragraph days, MoodKit for every day.

MoodKit’s honest shortfalls next to Journal: no photos or audio, no Mac app, no dark mode, no permanent free tier, and it’s a young app next to something Apple ships to every iPhone. Journal’s shortfall next to MoodKit is the one it’s least likely to fix: it will always ask how you feel and never tell you why.
