Do you read your bookmarks? Most of us have aspirations to read them, but few of us ever do. Ephemera makes sure you read everything you save while it's still relevant. Unlike other apps that save bookmarks that stay unread forever, Ephemera sets you a deadline that the bookmark must be read by. Don't worry, you'll be reminded before the deadline expires — but miss it, and that bookmark is gone. It couldn't have been important anyway, right? Anything that you do read is kept around for future reference, too. Expiring bookmarks are what makes Ephemera so special — because it encourages you to read what was important enough to bookmark in the first place, instead of letting it sit in a list that never gets looked at. Long lists of unread bookmarks create anxiety where it has no place, and Ephemera prevents that from happening. Features include: - Configurable default expiration dates for your bookmarks. - Configurable notification reminders so you'll always know before a bookmark expires. - Reading statistics that show how much you're reading and how often bookmarks go unread. - Widgets to put your bookmarks on your Home screen. - Bookmarks that sync across iPhone and iPad. - Keyboard shortcuts for easier bookmark navigation. - Quick and easy saving of bookmarks from within Safari and other apps. - Open Ephemera with a URL on your clipboard and save it as a bookmark with a tap. You can use Ephemera on your iPhone and iPad so your bookmarks are always with you no matter where you are or which device you are using. Ephemera is free to download with an optional Ephemera Premium purchase. Ephemera can be used without it, but a default expiration date will be applied to all bookmarks and notifications will be restricted. We take your privacy very seriously and believe that your data is your own. That’s why Ephemera doesn’t collect any of your personal data whatsoever.
