You can tweak this via the Settings. You have the option to either turn Journaling Suggestions off completely or pick and choose which ones you want to keep on including Activity (your workouts and exercises), Media (podcasts and music you listen to) Contact (people you message and call), Photos (library, memories, and shared photos) and Significant Locations (places where you spend time). Since I don't care to write about my phone calls or texts or my locations, I turned off Contacts and Significant Locations.
Journal is also included within the share sheet in all apps. So, if you're scrolling through content outside the app, you can tap the Share button and select Journal to send content right into the app. You can also write about new music you discovered on Spotify, a funny meme from Twitter, or an interesting TikTok.
What About Notes?
If I were using The Alignment System to describe the difference between Notes and Journal, I'd categorize the Notes app as Chaotic Good and the Journal app as Lawful Good. I still use my Notes app for fleeting thoughts: story ideas, grocery lists, passwords, packing checklists, email addresses, and recipes. If you were to scroll through each entry, you'd find a very wide range of things. There is no rhyme or reason to it. But the Journal app is strictly reserved for my memories and thoughts. There's a sense of order when you scroll through it.
Unlike the Notes app, the Journal app is passcode-protected. Depending on the iPhone model you have, you can either use a numerical passcode, Touch ID, or Face ID. So, you don't have to worry about people reading your deepest, darkest secrets.
However, there are some Notes-specific features I wish Apple would've incorporated into Journal. For starters, it'd be nice if there was a search bar to look up entries. Instead, you can only search based on categories: Photos, Videos, Reflections, Places, and Bookmarked (you'll have to bookmark entries for them to appear here manually). I can imagine it'll become fairly frustrating over time as you rack up entries.
I also wish Apple would've extended the app to the rest of...
