Duobench: Duo Split Screen

Split your screen into real tools: notes beside a PDF, a browser beside your tasks, the clipboard beside your snippets. Up to four panes on one screen, on iPhone, iPad and Mac. No account, no ads, no tracking. Your data stays in your own iCloud. Duobench puts the small tools you reach for all day in one workspace. Make a workspace for each kind of work and it remembers its layout, rearranging itself to fit whatever screen you're on: one pane on a phone, two or three on a larger screen, four on a big display. ONE SCREEN, MANY PANES • Panes reflow by themselves when you rotate, resize a window or use iPad multitasking • Switch the tool in any pane from the header, or drag a tool from the rail onto a pane • Open two copies of the same tool: compare two PDFs, or keep two notes open side by side • Hide the header and rail to give your panes the full screen START FROM A TEMPLATE Blank, Developer, Study, Creator, Meeting or Research. Each starts with the right tools already in place, and you can change everything later. TWELVE TOOLS IN ONE APP • Notes: folders, and empty notes clean themselves up • Tasks: Today, Upcoming, All, Flagged and Done lists with due dates, edited right in the list • Clipboard history: links, emails, phone numbers, hex colors and JSON are recognized, each with matching actions. Pin what you keep • PDF Reader: search, night and sepia themes, a full-screen reading mode and Capture Text • Browser: type an address or search privately with DuckDuckGo; your bookmarks are on the start page • Bookmarks: paste a link and Duobench fetches the page title • Snippets: reusable text with fill-in blanks like {name}; {date} and {time} fill themselves • Focus Timer: focus sessions with short and long breaks, a daily session count, an alert when each phase ends, and a Live Activity • Calculator • Unit Converter: length, weight, temperature, volume, area, speed, time, data, energy, pressure and angle, starting with units that fit your region • Dev Toolbox (Pro): format JSON without reordering keys, sort keys, Base64 and URL encode/decode, decode JWTs • Scanner (Pro): scan documents with the camera or pick a photo, and get the text on device CAPTURE TEXT, EVEN FROM SCANS Draw around any part of a PDF page to copy its text. On scanned PDFs with no text layer, Duobench reads the page on device to pull out the words. SEND BETWEEN TOOLS Send text from one tool to another: a link to Bookmarks, a line to Tasks, a quote to Notes, a token to the Dev Toolbox, any text to your clipboard history or Snippets.
