Super simple planner without the fuss. Tweek feels as natural as pen and paper. It's a minimal weekly planner and to do list built around one clean week view, with no hourly slots and no clutter. Organise tasks, reminders and notes, share your week with your family or team, and sync it both ways with the calendars you already use. - Week, day and month views Tweek opens in the week view by default, with no hourly scheduling. We think it's the best way to organise your life and work without stress. You see the whole week at a glance and simply move things around. Zoom into a single day planner when you need focus, or switch to the month view for the bigger picture. Use it as a weekly planner, a shared family calendar, or a simple day planner. - To do list, notes, checklists and subtasks Note down your thoughts in a text editor, break big items into subtasks, and build checklists. Attach files to any task, so the document you need sits right where you'll look for it. Everything lives next to the day it belongs to. - Two-way sync with Google, Outlook, Apple Calendar and Reminders Full two-way sync, not just import. Add or edit something in Tweek and it shows up in Google, Outlook and Apple, and anything you change there flows straight back into your week. - Web, iPad and Mac apps Tweek works on iPhone and iPad, on Mac, and in any browser. Start your week on your phone, plan it properly at your desk, tick things off on the go. Your calendar and your tasks are the same wherever you open them. - Colours and custom themes Paint any task any colour you like, and build your own colour theme for the whole calendar. A cosy highlighter and paper feel, in an aesthetic minimalist design. - Reminders and custom recurring tasks Get reminders by email or push notification so nothing slips. Set up recurring tasks on your own pattern: every few days, on specific weekdays, or whatever your routine actually looks like. Build it once and let it run. - Share and collaborate Share your whole weekly planner or just a single task, and work on it together with your team or family. A shared calendar that people actually read. - Your printable paper planner template Go beyond online planning. Print your week filled out or empty and do whatever you want with it: pin it to the wall, use it for a brainstorming session with your team, or hand your schedule to a client. Questions or ideas?
