8 Best Long COVID Apps for Apple Watch, Ranked

Body Insights is the best Apple Watch app for long COVID. Its Pacing mode learns your limits from your own Watch data and forecasts today's energy. It also flags a run of busy days before the crash. Download Body Insights to see today's forecast from data your watch already records.

Long COVID often punishes a good day. You feel well, do more, and pay for it a day or two later. A plan built from your own history helps you stop before that point, not after it.

Here is how that works in practice. Say you walked more than usual for three days in a row. Body Insights flags the extra load before you plan a fourth busy day. Your Apple Watch records heart rate, HRV, sleep, and steps in Apple Health. Each app below reads those records for one job.

The other seven apps earn their own awards. MindfulPacer comes from long COVID researchers in Zurich. Trackuility links your crashes to the days before them. TachyMon watches for sudden heart-rate spikes. Pace by Athlytic sums up your day in plain English.

All eight apps run on Apple Watch. We checked every listing on the US App Store on October 1, 2026. For pacing basics, start with our chronic illness and Apple Watch guide hub.

Our picks

1. Body Insights: Best overall for long COVID pacing

Body Insights has a Pacing mode built for energy-limiting illness. Turn on Manage a Chronic Condition, and it learns your usual activity range from your own Watch history. Each day it forecasts the energy you have. It flags days that run close to your ceiling. It also flags the day after three days above your norm.

Pacing also spots days when light movement costs your heart more than usual. Step counts miss that signal. One question about post-exertional malaise (PEM) sets the advice.

The daily check-in takes a few taps. Rate the day from Very rough to Good. Tag symptoms such as brain fog or dizziness on standing, and add a note. You can also mark a day that got worse after activity. Symptoms like fatigue and headache save to Apple Health, next to your heart and sleep data.

Its Body Battery, built for variable energy, is free on iPhone. So are the stress, HRV, and sleep scores. Premium unlocks Pacing, the Watch app, and an illness alert. That alert reads seven signals, such as HRV, temperature, and heart rate. It aims to flag illness risk two to three days early.

Pacing lives on iPhone.

Our verdict: Install Body Insights first. It learns your limits from your own data, then warns you before a busy streak turns into a crash.

2. MindfulPacer: Best free pacing alerts from long COVID researchers

MindfulPacer comes from researchers at the University of Zurich. The Long Covid Switzerland association supports the project. You set your own limits for heart rate and steps, over time windows you choose. When you pass one, your Apple Watch or iPhone notifies you.

Each alert saves as a "Reflection" in a journal. Link it to what you were doing, and add symptoms or a comment. Over a few weeks, the charts show which activities drain you most. Say every alert lands during grocery runs. You can then split the shop into two short trips.

Your data stays in the app on your device, and you can export it any time. MindfulPacer is free. It's new, with no ratings yet on the US App Store.

Our verdict: The best free alert app built with the long COVID community.

3. Trackuility: Best for crash (PEM) reports

Trackuility is made for people who pace ME/CFS, POTS, and long COVID. You set a pacing profile for the day from your energy budget. Then you set your own limits, with a notification when you go over. It tracks 17 metrics, including heart rate, HRV, steps, and walking speed.

Each limit runs across windows from 15 minutes to three days. A calendar shows each day you went over. You can log symptoms and notes on any day.

Its PEM reports stand out. Pick a crash, and Trackuility lines it up with your health data from the days before. That helps you spot the push that came first. Trackuility is free to download and has 5 ratings.

Our verdict: Our pick for tracing a crash back to what caused it.

4. PaceME: Best for rating how much energy you feel

PaceME is designed for ME/CFS, and its developer lists long COVID and POTS as fits too. Each day you rate your capacity on a scale from 1 to 5. Your own rating outweighs the sensor data. The app shows HRV, resting heart rate, sleep, and steps beside it.

Before an activity, check your readiness. A cautious three-day forecast helps you plan the week. On Apple Watch, you can log capacity from your wrist and start a Live Pacing session. Alerts are based on your personal HRV baseline.

PaceME also shows a Weather Load from air pressure and temperature. That helps if your symptoms shift with the weather. You can export a PDF report or CSV file. Health data stays on your devices. PaceME costs $9.99 and has 2 ratings.

Our verdict: The best fit if how you feel should count more than what the sensors say.

5. Pace by Athlytic: Best plain-English daily summary

Pace is a new app from the team behind Athlytic. It reads more than 35 signals from your Apple Watch. These include HRV, resting heart rate, sleep, and walking speed. You don't need to enter anything.

Pace learns your baselines over 60 days. Then it speaks up only when something shifts, in a sentence like "Your heart rate variability is lower than usual." It also tells you when a concern clears. Premium adds an AI assistant you can ask about your data, weekly summaries, and PDF reports.

Pace needs iOS 26. It has a 4.5 rating from 56 reviews.

Our verdict: The calmest way to notice a change without reading charts on a foggy day.

6. TachyMon: Best for heart-rate spike alerts

If your heart races when you stand, TachyMon taps your wrist when your heart rate crosses a line you set. You can set upper and lower limits. You can also set a limit for change from your recent average.

Each alert saves with its start time, length, and peak or lowest heart rate. A triple tap silences alerts for a while. The core alerts are free. Premium adds notes and symptoms on each alert, PDF reports, and CSV export.

Our verdict: The best free alarm for sudden heart-rate spikes on Apple Watch.

7. Gentler Streak: Best for gentle movement on good days

Gentler Streak suggests each day's activity from your readiness, from rest to hard exercise. The Watch app lets you scale a workout's length or effort up or down. Rest days keep your streak alive. When you're ill, you can set your status to match.

Its step view shows a 14-day trend without pushing a step goal. Gentler Streak won the 2024 Apple Design Award for Social Impact. Advanced features need Premium.

Our verdict: The kindest way to move on good days without chasing rings.

8. HeartWatch: Best for detailed heart charts

HeartWatch charts the heart data your Apple Watch records. It splits your heart rate into daytime, sedentary, sleeping, waking, and workout views. It sends background heart-rate alerts on the Watch, with context. You can add notes and readings from your wrist, like blood pressure or temperature.

Every metric exports, so you can bring a clear chart to your next visit. HeartWatch runs without ads or user tracking. It costs $8.99.

Our verdict: The richest heart charts on this list, for a one-time price.

Why Body Insights wins for long COVID

Each of the other seven apps does one job well. MindfulPacer and Trackuility alert on limits you set. TachyMon watches for spikes. Pace and HeartWatch explain your data. Body Insights answers the question that comes first: how much can you do today?

Its Pacing mode answers from your own history instead of a generic step goal. It learns your ceiling, forecasts your day, and flags extra load from the last three days. Its check-in then saves how the day felt to Apple Health. Body Battery and the core scores stay free on iPhone.

We recommend a different first app in two cases. If heart-rate spikes on standing are your main problem, start with TachyMon. If you want a free alert on a number you pick, start with MindfulPacer.

Many people use two apps. Pair Body Insights with TachyMon for live alerts or Trackuility for crash reports.

Where Visible fits

Visible is a popular pacing app for long COVID, but it has no Apple Watch app. It measures HRV and resting heart rate each morning with your phone's camera. All-day pacing alerts need the Visible band, which is sold in the US and UK. Visible explains why it doesn't use Apple Watch data.
