Spread Planner is a planner that shows your week and your handwritten notes as a two-page spread. - Opens like an A6 planner The inner display of iPhone Duo has almost the same proportions as A-series paper. Open it and your week sits on the left page and your notes on the right, just like an open A6 planner. Half-open it and the fold becomes the spine. Close it to see just today's page. - Your week on the left, handwriting on the right Type your plans for each day on the week page. Events from your iOS Calendar appear right on the lines (read only, never changed). Write by hand on the note page. - Choose your paper Lined and grid paper are free. Pro adds dot, blank, timeline and two-column paper, and you can pick a different paper for every week. - Monthly spread (Pro) See the whole month across two pages. Like a paper planner, the seven days span both pages, with monthly notes at the far right. Tap a day to jump to that week. - Works on regular iPhone and iPad On iPhone, flip between Today, Week, Notes and Month with the switcher at the top. Turn iPad sideways for the spread. - Night paper In Dark Mode the page turns to a softer "night paper". - Your writing stays on your device No account needed. Everything you write is stored only on your device and never sent anywhere. No ads. - Pricing Week pages, handwritten notes, lined and grid paper and calendar events are free. Spread Planner Pro (one-time purchase) unlocks the monthly spread and every paper type.
