    Context Switching: Keep Tasks, Notes and Email Together

    The task in one app, the email in another, the note in a third. What switching costs, and how to keep everything about one thing in one place.

    By Shekib AzizPublished Updated 9 min read

    The task is on your board, the email about it is in your inbox, the notes are in another app, and the decision was made in a chat you can't find. Every time you pick the task up, you spend the first few minutes rebuilding the context.

    That rebuilding is context switching, and it costs more than it seems. This guide covers why switching between tasks and apps wears you out, what research says it costs, and a simple fix: link everything about one piece of work together, so picking it up means opening one thing, not four.

    What is context switching, and why does it tire you out?

    Context switching is moving your attention from one task, or one tool, to another. Reading an email halfway through a report is a switch. So is leaving your task list to look for a note, then opening a chat to find what you decided.

    Each switch looks free: you are only gone for a moment. The trouble is that your mind does not come back all at once. Sophie Leroy, a professor of management and dean of the UW Bothell School of Business, calls what stays behind attention residue. Part of your attention is still on the thing you left while you try to start the next one.

    That is one reason for what people call context switching fatigue: a day of constant switching can feel draining even when little got done, because so much of it went on restarting. Leroy's own advice includes writing things down, which helps the brain let go and return more easily. Hold on to that: it is half of the fix.

    If the switches are to your phone rather than between work apps, see how to stop getting distracted.

    How much time does switching between apps cost?

    More than it feels like. For a study in Harvard Business Review, researchers followed 137 people on 20 teams at three Fortune 500 companies for up to five weeks, and counted how often they toggled between apps and websites.

    About 1,200 a day

    They found workers toggled roughly 1,200 times each day, which adds up to just under four hours each week reorienting themselves after toggling

    Each switch cost a little over two seconds to get back on track. Tiny on its own. Over a week it came to about 9 percent of their time at work, spent finding their place again.

    The same sums run outside work. Paying one bill can mean the email with the amount, the note with the account number and the calendar for the due date. The real context switching cost is not the seconds. It is starting over, again and again.

    Is one app better than many?

    Having too many productivity apps is a real problem, and the usual answer is an all-in-one productivity app. Fewer places to look does help. But one app is only half the fix if the email, the note and the task still sit in three different corners of it.

    What matters is that everything about one piece of work can be found from one place. The searching is what wears you down: in Microsoft's 2023 survey of 31,000 workers in 31 markets, 62% said they struggle with too much time spent searching for information in their workday. So the goal is not one app for everything. It is one starting point for each thing you are working on.

    Four places to look

    1. Open the taskTax return
    2. Search your inboxfor the accountant's email
    3. Find the notein another app
    4. Scroll back through chatsfor what you decided

    One place to start

    1. Open the taskTax return
    2. Tap what is linkedthe email, the note, the chat
    3. Back to the worknothing to rebuild
    IllustrationThe same task, picked up twice. Linked, there is nothing to hunt for.

    Two ways to pick up the task Tax return. On the left, four places to look: open the task, search your inbox for the accountant's email, find the note in another app, scroll back through old chats. On the right, open the task, tap what is linked to it, and get back to the work.

    How do I keep the email, the note and the tasks for one project together?

    Link them. Choose the thing you will come back to most, usually the task, and attach the rest to it: the email that started it, the note with the details, the chat where you worked it out.

    In Ranya, tasks, notes, emails and chats can all be linked to each other, and every link goes both ways. Link a note to a task and the note shows on the task, and the task shows on the note. On your board, the card carries small icons for what it is linked to. Open the task, and a tap on the link icons at the top of it shows them all.

    So it does not matter which end you pick up. Some work starts as an email, some as a task, some as a thought you wrote down. Whichever you open next, the rest is there.

    How linking works in Ranya, and why links go both ways

    Ranya keeps your tasks, your notes, your Gmail and your chats with Ranya in one app, and links are the thread between them. We made links two-way because work does not start in one place, and you should not have to remember where it did. There are three ways to make one:

    • From an email. Gmail triage sorts your inbox into Reply, Do and Skim, and changes nothing until you approve. Approve a Do and Ranya creates a task linked to that email. More on that in how email triage works.
    • From anything open. A task, note, chat or email has a link button at the top. Pick Task, Chat, Email or Note, search, and choose.
    • On a call. Ask Ranya to link a note to a task. She reads the change back and waits for your yes before making it. By voice you can link tasks and notes; emails and chats are linked with the link button, or, for an email, by approving a Do.

    Example email from the accountant, Documents for your return, sorted by triage as Do, with Approve, Label, Why and Change. After you approve it, the Done today list reads: Created a task linked to this email, and it shows in your Inbox list. The new task Tax return shows one linked email.

    For the few things you keep coming back to this week, there is the pinned strip along the bottom of every page: tasks, notes, emails and chats in one row, most recently pinned first, with Ranya at the end of it.

    Linking a project together, step by step

    One example project, start to finish: a tax return, an email from the accountant, a note and a chat.

    1. Start from the email

      In your Gmail inbox, triage marks the accountant's email Do, or you change it to Do. Approve it. Ranya creates a task linked to the email, and it shows in your Inbox list. Here it is called Tax return.

    2. Link the note with the details

      Open the task and tap the link icons at the top. The accountant's email is already there. Choose Link note (on a narrow panel, Link, then Note), search for Tax notes and pick it, or choose New note to start one from the same screen.

    3. Link the chat where you worked it out

      Same panel, then Link chat. Pick the conversation with Ranya where you sorted out which receipts count. The chat now shows the task too.

    4. Or link the note on a call

      Instead of step 2, say "Link my tax notes to the tax return task." She finds both, reads the link back, and makes it when you say yes.

      You: Link my tax notes to the tax return task.

      Ranya: Link Tax notes to Tax return?

      You: Yes.

      Ranya: Done. Each one now shows the other.

      Example callShe reads the link back first, and links them only after your yes.
    5. Pin it while it is active

      Tap Pin task at the top of the task, or say "Pin the tax return." It joins the pinned strip, so it is on every page until you are done. Pin the note the same way if you will keep going back to it.

    6. Open any of them

      Open the note from the strip and the task is linked at the top of it. Open the task and the email is a tap or two away. Wherever you start, the rest comes with you.

    Example stripPin what you are working on this week. Every pin is one tap from any page.

    Example pinned strip at the bottom of a page, with four pins from left to right: the task Tax return, the note Tax notes, the email Documents for your return and the chat Which receipts count?, then Ranya at the right end.

    How can I reduce context switching day to day?

    • Finish the thought before you switch. Before you leave a task, write one line in its linked note about where you stopped.
    • Check email in sittings. Triage marks what needs doing as Do; approve it and it becomes a linked task, so the inbox can wait while the work stays in view.
    • Stay where you are. With the Mac or Windows app running, you can call Ranya from any app without switching windows.
    • Clear up when it is done. Complete the task and unpin it; the note and its links stay where they are. Anything you do delete (tasks, notes and chats) waits in one Trash for 30 days.

    Frequently asked questions

    What is context switching?

    Context switching is moving your attention from one task or tool to another. Each switch costs a little time to reorient, and part of your mind stays on the thing you just left, so a day of constant switching feels tiring even when little got done.

    How much time does switching between apps cost?

    More than it feels like. Each switch is short, but they add up across a day of moving between email, chat, documents and task lists. Keeping the things that belong together in one place cuts down how often you have to switch.

    Is one app better than many?

    Not always, but fewer places to look is better. What matters most is that everything about one piece of work can be found from one place, which you can get by linking the task, the email, the note and the conversation together.

    How do I keep the email, the note and the tasks for one project together?

    Link them. In Ranya, tasks, notes, email threads and chats can be linked to each other, and each linked item shows on the others, so the email and the note are a tap or two away from the task.

    Can I link things by voice?

    Yes, for tasks and notes: say something like "link the budget note to the tax return task" and Ranya asks before linking them. Chats and emails are linked with the link button at the top of them, and an email also by turning it into a task.
