ShelfNote
Read full descriptionHide full description
ShelfNote is a personal smart shelf designed to help you remember what you want to watch, read, listen to, play, or discover later. Instead of adding a movie, series, book, album, podcast, or game to an ordinary list, you place it on a shelf of your own. Create its label, edit the text, adjust its size and position, then leave it in its place on your shelf. With ShelfNote, you can: • Keep everything you want to watch, read, listen to, and play in one place. • Add completed items to your collection. • Create shelves for Movies & TV, Books, Music, Podcasts, and Games. • Design a custom label for every item. • Arrange and reorder the objects on your shelf. • Share your shelf and show your collection to others. • Quickly open supported platforms and stores related to your saved items. ShelfNote turns digital lists into a more personal and visible experience. Your saved items do not disappear into another folder; they take their place on a shelf that feels like yours. No account is required. Your data stays on your device. An optional Style Pack lets you personalize your shelf with alternative shelf themes and object designs.

Verdict
The clearest difference is ads: ShelfNote at none against Simple Clock's shown. Simple Clock's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 17.0). On price and in-app purchases there is nothing between them.
