The author has tested over 20 read-it-later apps and recommends four of them as the best options: Pocket, Instapaper, Omnivore, and Safari Reading List. The author evaluates apps based on their ability to save articles for offline reading, offer custom typography and color schemes, make it easy to organize archives, work on multiple platforms, and provide a good user experience. Pocket is considered the most feature-complete app, but has some drawbacks such as clutter. Instapaper offers speed reading features and can send articles to Kindle devices, while Omnivore is a free and open-source option that can pull in newsletters automatically and offer webhooks integrations. Safari Reading List is a great option for Apple loyalists who want a built-in reading list that syncs across devices. Other alternatives include note-taking apps like OneNote and Evernote, and bookmarking tools like Pinboard and Google Bookmarks.
