Organize your PDFs, set custom covers, and choose from several theme colors and icons, for a pleasant reading experience just the way you want it. • Create folders and folder groups to keep your PDFs organized however you prefer. Rename and rearrange things as the mood takes you. Name every single book and folder the same thing, if you really want to! (I don’t recommend doing that, but nonetheless, that’s the sort of awesome power that you wield if you use BookFolder.) • Set custom cover images for every book (or stick with a book’s default cover, of course). Your library will look the way that you want it to! (And the underlying files remain pristine, so if you begin to regret choosing a photo of your cat for every book in your collection, you can always restore the originals and no one will know. Except your cat, who is judging you now.) • Get wild on an iPad with split-screen multitasking support. Read two books at once (or the same book twice)! If that’s something that you want to do. • Swap between five theme colors, for an interface that works best for you. (Dark Mode support, too, of course!) • Choose from a dozen icons, from solid colors to subdued platinum to a retro rainbow look, to fit your mood and to ensure a harmonious home screen layout with your other apps. (I’m not the only one who arranges my icons by color and design… am I?) • You can use it to actually read the PDFs, too, of course. Mustn’t forget that part. • Plus bookmarks, searching, and table-of-contents support, as one would expect. • Also, it’s free, no in-app purchases, no tracking… just a nice PDF reader and library manager. I hope that you’ll enjoy it!
Grimoire
Read full descriptionHide full description
Fifty dark and beautiful stories, written for the quiet hours after the world goes to sleep. Grimoire is a collection of gothic fables — lantern-lit tales of courage and loss, of strange bargains and small wonders, told in the tradition of the folklore that has always been a little frightening and a little wise. Each story is a self-contained world: a lighthouse that goes dark after a hundred years, a clockmaker who steals hours, a girl who plants a door in the earth and waits to see what walks through. They are the kind of stories meant to be read slowly, alone, by whatever light you have. If you love dark fantasy, gothic atmosphere, and short fiction with real weight — the mood of old fairy tales before they were softened — this is a book made for you. WHAT'S INSIDE - 50 original stories, each a complete tale in three chapters - Around ten minutes a story — perfect before sleep, on a commute, or whenever you need to slip somewhere else for a while - Four levels of depth, from short and haunting to long and layered - Hand-crafted cover art for every single story, in a dark ink-and-shadow style - A reader built for the night: warm type on a deep background, easy on the eyes BUILT FOR READING Grimoire isn't a feed and it isn't a game. There are no timers, no streaks, no noise. Just a quiet shelf of stories and a reading experience designed to get out of the way. Mark your favorites, pick up exactly where you left off, and let one tale lead into the next. The whole collection lives in a single dark, distraction-free space — the kind of app you open when you want to disappear into a story instead of scrolling. START FREE Three stories are yours to read right away, at no cost. Unlock the full grimoire — all fifty tales — with Grimoire Pro, available monthly or annually with a free trial. One purchase, the entire collection, always yours to return to. Open the book. Light a lamp. See what's waiting inside. https://app.notion.com/p/Grimoire-Privacy-Policy-EULA-3c72f13e5f7d80dea134d6ef542fe560?source=copy_link
