Read full descriptionHide full description
NextPaper is a Zotero companion that turns your library into a reading queue. Zotero is great for collecting papers, but it’s easy to lose track of what to read next. NextPaper gives your library a simple structure you can actually work through. Browse your collections, pick papers that matter, and add them to your NextPaper list. When you finish reading something, mark it as read and move on. Your progress is reflected directly in Zotero, so everything stays in sync. See the essentials at a glance — title, authors, abstract, and publication — without needing a desktop app. Designed for researchers who already use Zotero. There’s no new account to create. Just connect your library and start organizing your reading. Your data stays yours. NextPaper uses secure OAuth to connect to Zotero and doesn’t store your password or your library content.

A time tracker that splits your day into 15-minute blocks. That's the whole idea. 96 blocks a day, from when you wake up to when you go to sleep. You write down what you did in each one. Nothing more complicated than that. We promise it will change the way you work, the way you doomscroll, and the way you function. Not because it nags you, but because for the first time you'll see, in plain numbers, exactly where your time goes. This is a new way to be productive. You don't plan your day. You track it, fifteen minutes at a time. (4x 15 minute blocks make an hour. A day equals 96 blocks.) HOW IT WORKS 1. Open the app, no account, no sign-up. 2. Tap any 15-minute block and type what you just did, like "deep work," "lunch," or "doomscrolling." 3. Give the block a category, like Work, Gym, or Sleep, so you can see where your time goes. 4. Did one thing for hours? Fill the whole stretch with a single category in one step. 5. Open Stats and watch your real day show up in color. Five minutes of tracking a day. That's the entire commitment.
