Long COVID and everyday memory

Long COVID brain fog: keeping track of everyday tasks

If Long COVID brain fog makes it hard to keep track of everyday tasks, try putting the details in one place and using a reminder to return to them. Name a small, specific action and keep flexible tasks easy to move. An alert can bring something back to your attention; it cannot tell you whether you have the energy to do it.

We build Poko, a WhatsApp reminder service. Below are practical examples you can edit, alongside options such as paper notes and phone reminders. This is a guide to keeping track of tasks, not a treatment for Long COVID or a plan for increasing your activity.

Why keeping track can feel different after COVID

Brain fog can involve difficulty concentrating, slower thinking, short-term memory problems, or trouble finding words and organising tasks. University College London Hospitals (UCLH) explains that these symptoms can fluctuate, even within a day. A routine that felt manageable yesterday may feel harder today.

UCLH suggests external aids such as notes and alarms, and reducing how much information you handle at once. These are ways to support a task. They do not establish that a particular reminder app improves brain fog.

Make room for rest before adding more prompts

Some people with Long COVID experience post-exertional malaise (PEM): symptoms worsen after physical or mental effort. The CDC notes that this worsening often appears 12 to 48 hours after activity and can last days or weeks. Feeling able to do more in the moment does not always tell you how you will feel afterwards.

UCLH's fatigue guidance treats thinking and emotional demands as part of activity too. It recommends individual pacing, planning, and prioritising, including deciding what can wait or where someone else could help. Work with your healthcare professional on a plan that fits your symptoms, especially if activity leads to a crash.

A reminder can support that plan. It should not become a reason to push through worsening symptoms or keep extending a work session. The example times in this article are editable placeholders, not recommended work or rest intervals.

Save enough context to find your place again

Choose somewhere comfortable to keep the details: a notebook, a note on your phone, or a calendar entry. A reminder can then point you back to it. For example, returning a parcel may involve finding an email, checking the return instructions, and arranging a collection. You do not need to hold that sequence in your head.

  1. Write down where things stand

    A note such as “Return requested; instructions are in the shop's email” gives you a place to restart.

  2. Name the next action

    A prompt to find the returns email tells you what to open. Add the shop's name if that will help you identify it.

  3. Keep the deadline separate

    Record the actual return deadline in your calendar. Moving a reminder does not extend a shop's return window.

Try one ordinary reminder on WhatsApp

If WhatsApp is comfortable to use, the button below lets you try the reminder flow. It opens Poko with a message already typed. Edit it if needed, press Send, and check the task and time in Poko's confirmation. Check the timezone in its welcome message too. Opening the button alone does not schedule a reminder.

Keep your phone connected, enable WhatsApp notifications, and leave the Poko chat unmuted if you want an alert. See whether the message is easy to notice and understand. If using your phone is tiring or distracting, a visible note or another aid may fit better.

These examples send reminders to your own WhatsApp number. Poko's first 7 days are free, with no card required. A paid subscription is needed afterwards to keep reminders running.

Return to one piece of unfinished admin

For the parcel example, start with finding the email. Change the time and wording below to match your task. If someone is helping with the return, agree who will do the next step so the reminder does not duplicate their work.

Once it is done, update your note. Poko does not read your email, check the return deadline, or detect whether the task was completed. The message simply brings you back to the action you named.

Keep a reply without committing to a conversation now

If you need time before answering a message, save who it is from and what needs an answer. You might send a brief acknowledgement yourself, then choose a later time to reconsider the reply. You can change the plan if that time no longer suits you.

In the example below, replace Maya and Saturday with the details you need. This creates a reminder for you; it does not send Maya a reply, read her messages, or commit you to meeting up. If a response has a deadline, keep that in your notes too.

Keep a few notes for your healthcare professional

Speak with a healthcare professional if you think you may have Long COVID, or if memory and concentration difficulties are new, changing, or affecting daily life. A reminder app cannot identify the cause. The NHS describes personalised support, which can include help with fatigue and cognitive rehabilitation.

The NHS also suggests a symptom diary. If it is manageable for you, a brief note can record what happened, its effect on an everyday activity, and anything you noticed beforehand or afterwards. If keeping notes is too demanding, ask about a simpler approach or help recording them.

The button is a prompt to open your own diary. You do not need to send medical details to Poko, and Poko does not assess symptoms or share updates with your care team. Do not wait for a reminder to seek help with a concern.

Take your questions into the appointment

The CDC's appointment checklist recommends preparing questions and describing how symptoms affect everyday activities. Choose the questions that matter most to you. For example: “I lose track while reading instructions. What support could help?” or “I feel worse the day after concentrating on paperwork. How should I manage that?”

Set a preparation reminder before your actual appointment, if useful. You can ask for written instructions or an appointment summary afterwards. If you want a trusted person to help remember the conversation, discuss that with them beforehand.

Make reminders easy to change or stop

If a flexible task no longer fits your day, move it or cancel the prompt. In Poko, send “list” to see pending reminders, then ask to change the relevant one. To remove it, use “cancel N” with its number from the latest list. If a one-off reminder has already arrived, send a new request if you want another prompt later.

Repeating reminders follow the schedule you set while your trial or subscription is active, until cancelled. They do not stop automatically when the task is done or adapt to your symptoms. More notifications are not necessarily more useful; keep the prompts that help you find what you need.

Questions, answered

Can a reminder app help me keep track of tasks with Long COVID brain fog?
A reminder can bring a specific task back to your attention. A note can hold the details you need when you return. Try a setup you can comfortably use, and change it if it adds more effort. A reminder app does not treat brain fog or tell you when an activity is manageable for you.
Can thinking and concentrating make Long COVID symptoms worse later?
Some people experience post-exertional malaise after mental as well as physical effort. The CDC describes symptom worsening that often appears 12 to 48 hours afterwards and can last days or weeks. Discuss this pattern with your healthcare professional rather than using alerts to push through it.
What if I cannot manage the task when the reminder arrives?
For a flexible everyday task, you can move it, cancel the prompt, or ask someone for help. Keep actual deadlines and appointments visible separately. Poko does not assess your symptoms or change your schedule automatically; a message arriving is not an instruction to keep going.
Will Poko send the reply or update my symptom diary for me?
These examples create reminders to do those things yourself. They do not read or reply to another person's messages, update a diary in another app, or send information to your healthcare professional. You can keep the personal details in your own notes.
Do I need to pay or send a message to try an example?
The first 7 days are free, with no card required. Open an example, edit it, press Send in WhatsApp, and check the confirmation. Opening the button alone does not schedule anything. A paid subscription is needed afterwards to keep reminders running.
