Do more and plan less. Get things off your mind and into a trusted system. Get things done without stress. Manage your commitments as Next Actions and Projects. DoNext helps you to pick what to do next. No need to constantly rethink your tasks. DoNext assists you in two things: (1) Add and (2) Do. (1) Add - Decide your Project and Next Action Whenever you think of something e.g. "Rome vacation" enter the idea into DoNext. Later decide 2 things: • PROJECT: Desired outcome - How does success looks like, e.g. "Have fight ticket to Paris". • NEXT-ACTION: Physical next step - The next thing you can do towards the project, e.g. "search flight to Paris" with the context "online". A context is the location, situation or person required to do the next-action. (2) Do - Select your List Whenever you decide what to do next, filter in DoNext by context e.g. „market“, „online“, „team-meeting“, or „partner“ then pick a Next Action. STANDARD FEATURES • Tap a Next Action in the list to mark it as completed. • Completed items disappear the next day. You can still find all the actions in the search screen. • Decide the Next Action without moving your fingers from your keyboard. Swipe down in a list to create a Next Action for it. • Jot down ideas on the go: See Actions which need a context in the inbox. • Dynamic filters: Switching the context of an Action takes only 3 taps. • Go to links, edit or delete items by swiping them left. • Use Siri Shortcuts in iOS 12 to quickly go to a list. • Pull down in a list to create a similar Next Action. • End the next-action with "," to create an additional Next Action with the same Context. HERE IS WHY YOU WILL LOVE IT Benefits of (1) Add: Experience a great sense of clarity and perspective. Decided the Next Action for all your open loops. Splitting up all your desired outcomes in tiny Projects gives you great perspective. Since you only focus on the immediate Next Action you won‘t spend a lot of time on planing each Project. DoNext makes it feasible to have hundreds of Next Actions at the same time. If you don't have a system for your smaller commitments your head attempts to do it for you. If you don’t write a thought down and decide on it, you probably will be stressed about it again later without making progress on it. Benefits of (2) Do: Experience a great sense of focus, instead of rethinking your options all the time. Free your head from rethinking all your tasks. Working from your lists keeps your lists of To-Dos actionable and relevant. No need for manual task order, subsequent actions, "today view" or due reminders. Items are automatically sorted. HOW DONEXT FITS IN YOUR EXISTING WORKFLOW Ensure every item in DoNext could be done by you right now. Plan complex Projects where you need to track more than the Next Action on a separate document or system. Add the actions to DoNext as they become Next Actions. Create a tag PROJECTS and fill it with all your desired end results with multiple steps, e.g. "Organise flight to Italy". Decide the Next Action for each item in your inbox. Schedule time specific actions in your calendar. For all ASAP tasks use DoNext. Make DoNext your major source of todos for deciding what to do next.

TrackStack Time Management is a habit-forming time management tool designed to encourage and reward the intentional expenditure of time To use TrackStack, you simply create a category and press the screen to set a timer - with a duration based on how long you pressed. Once the timer ends (or you end it early) a 'Block' is dropped onto your daily stack, representing the time spent. Each day, as you consider how to spend your time, you'll steadily build a 'Stack' representing how often you considered your time, and what you decided to do with it. Over time, you can look over past days and weeks to gain perspective on your habits, and insight towards your goals.
