Quill: Diary & Journal
Private notes with a lock
Only for iPhone
Free · In‑App Purchases
iPhone
Your diary, locked, on this iPhone and nowhere else. No ads, no account, no server — nothing between you and the page. Import old entries, export to PDF.
Quill keeps what you write on this iPhone. No account, no sign-up, and no server of ours — so there is no company that could read your diary, and that includes us.
LOCK IT
A four-digit PIN and Face ID. Quill asks when it opens, and again after thirty seconds away. Forget the PIN and a recovery code lets you back in. The preview in the App Switcher is covered.
WRITE
Bold, italic, underline, colour, links, bullets, numbers and checklists. Three photos in an entry — twenty with Pro. A mood, in words rather than stickers. Tags. Write up a day you missed, however far back. Your draft is saved while you type, so a crash or a flat battery takes nothing with it.
FIND IT AGAIN
Full-text search across every entry, on the device, in milliseconds. Filter by tag, mood, photos, favourites or a range of dates. A month calendar shows the days you wrote on. On this day brings back the same date from earlier years, and stays quiet when there is nothing to show.
BRING AN OLD DIARY OVER
Import from Day One, Apple Journal, a folder of Markdown, or plain text and CSV. You see how many entries and photos were found before anything is written. Import the same file twice and nothing is duplicated.
TAKE EVERYTHING OUT AGAIN
Export to PDF, to a book with a cover and contents by month, or to Markdown with your photos in a folder. With or without Pro, and after you stop using Quill.
BACKED UP TO YOUR OWN iCLOUD
Entries and photos travel through your private iCloud database. Not ours. Turn it off and Quill still works, entirely on the phone.
QUILL PRO
Draw a page by hand with a finger or a Pencil, and open it later to carry on. Record a voice note — five a page, five minutes each — kept inside the entry. Scan a page of a paper notebook and have the writing read into it, shown to you to correct before anything is added. Share an entry as a card that starts with no words at all, only the date, and lets you choose how much more to include. More than one mood a day. Twenty photos an entry, reading fonts and sizes, more notebooks, your streak on the home-screen widget, advanced search filters, and the place and weather noted with each entry.
Not a subscription. The lock, iCloud backup, import, export, search, memories from past years and the daily reminder are not behind Pro and never will be.
English, Tiếng Việt, 日本語, 한국어, 繁體中文, Deutsch, Français, Español, Italiano, Nederlands, Português, Türkçe and العربية — changed inside the app, without touching your iPhone's own language.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixes, from a careful read of the whole app.
Bringing in a long diary, and the first iCloud sync on a new iPhone, both arrive in batches — and Quill was rebuilding the whole calendar once for every batch. Now the batches are gathered up and the work happens once, so importing and syncing stay out of your way. Search also notices entries as they arrive from iCloud, instead of waiting until the next time you open the app.
An entry that is only a voice note used to show up in the list as "(photos only)", with no sign of what was inside. It now says what it holds, and the card counts recordings the way it counts photos.
A share card set to "Date only" no longer carries the mood out with it — date only means date only.
Your notebooks now survive the round trip: export your diary, import it back, and every entry returns to the notebook it was in. Imports from Apple Journal bring their photos again. An entry with only a mood or a tag can be saved instead of being treated as empty. And when an import cannot finish, it says so and says how far it got, rather than reporting success.
Some damaged or hand-made files could close the app on the import preview screen. They cannot any more.
