The Best Apps for ME/CFS and Long COVID (2026)

Which ME/CFS or long COVID app is best for what?

With ME/CFS and long COVID, the app’s main job is to help you pace. That means noticing what costs you energy and what follows a day or two later. The apps below do that in different ways.

Prices are standard US prices. Ratings are from each app’s US App Store listing on 6 October 2026. [1] [2] [3] [4]

Who is Visible best for?

Best for: People with ME/CFS or long COVID who want heart-rate data to guide pacing and are happy to wear a band. If that is you, Visible is the specialist tool.

What stands out: Visible is designed for people with long COVID, ME/CFS, POTS, fibromyalgia and EDS. [5] The free app measures heart rate and heart rate variability with your phone camera each morning and gives you a Stability Score. You add evening check-ins for symptoms and a monthly check-in, then view Trends and create a Health Report PDF. With a paid membership and the Visible Band 2.0, you get all-day heart rate, heart-rate zones and PacePoints to help you manage daily exertion. [6] Visible says the app notifies you on your phone when you are over-exerting. [5]

Things to know: Membership is only available in the US and the UK, and prices are shown at checkout. Membership features work with Visible Band 2.0 or Polar Verity Sense, not an Apple Watch or Garmin. [7] [8] The Health Report needs 30 days of morning check-ins, and it leaves out all-day heart rate and PacePoints. [9] It runs on iPhone and Android, and is rated 4.8 from more than 3,500 ratings. [1] [10] We compare it with Juno in Visible vs Juno.

Who is Juno best for?

Best for: People who find typing or forms hard on bad days, and anyone who wants help planning a day around limited energy without buying a band.

What stands out: You can log a crash in one sentence, by voice or text: “I crashed after the school run and spent the afternoon in bed.” Juno logs the symptoms on the right day. [11] For pacing, Juno puts your planned activities, their estimated spoon costs and your symptom notes side by side, so you can compare options before you commit. [12] It also looks at your entries next to sleep, activity and data from 20+ wearables and health platforms. Before an appointment, it turns the last few months into a one-page summary. [11] If you already use Visible, you can import your Visible symptom history from its CSV export. [13] [14] See how Juno helps with ME/CFS.

Things to know: Spoon estimates are a rough planning aid, not a safe limit, and your own sense of your body comes first. The free plan has a monthly limit on AI chat; the optional Juno Pro plan removes that limit (check the app for the current price in your region). Juno needs an internet connection. [16] It runs on iPhone and Android, and is rated 4.8 from more than 10,000 App Store ratings. [2] [17]

Who is Bearable best for?

Best for: People who like rating their energy and symptoms each day and looking for what drains them.

What stands out: Bearable says it was built with people living with ME/CFS and long COVID. You can log flare-ups, crashes and good days, and work out which activities drain you or give you energy. It syncs steps, sleep and heart rate from Apple Health and Fitbit. [3] The free plan includes unlimited energy, mood, sleep and symptom tracking with 30-day trend and comparison graphs. [18]

Things to know: Correlation reports and longer report periods need Premium, at $6.99 a month or $34.99 a year. [18] [19] Post-exertional malaise is often delayed by hours or days, [20] so look beyond same-day links when you read any chart. It runs on iPhone and Android, and is rated 4.8 from more than 6,400 ratings. [3] [21]

Who is Guava best for?

Best for: People in the US with complex, multi-system illness who want medical records, lab results and device data next to their symptoms.

What stands out: Guava names ME/CFS and long COVID among the conditions it supports. It syncs records from US patient portals, pulls in data from wearables and health apps, and finds correlations between symptoms, medicines and lifestyle. [4] Its free plan includes symptom tracking, trends and correlations. [22]

Things to know: Symptom logging uses forms with severity, tags, notes, photos and a body map. [23] Automatic insights and the Guava Assistant need Premium, at $8 a month or $78 a year. It runs on iPhone, Android and the web, and is rated 4.8 from more than 900 ratings. [22] [4]

What if any screen is too much?

On some days, or with severe ME/CFS, even a phone is too much. That is fine. A paper sheet, or a few words someone else writes down for you, still counts.

Our free energy and fatigue tracker is a printable week with room for next-day symptoms, so delayed crashes show up. If a phone is fine but an app feels like too much, the free symptom tracker on our site takes a few taps and needs no account. For the reasoning behind that, read how to spot your PEM window.

Do pacing apps prevent crashes?

Not reliably, as far as current evidence shows. In a randomised trial of 250 adults with long COVID, one group used a pacing app with a wearable that sent messages at 50%, 75% and 100% of their daily activity allowance. The other group used the app with data entry only. After six months, post-exertional malaise was no different between the groups. The authors note that natural recovery in long COVID may have hidden an effect, and suggest testing the approach in ME/CFS. [24]

NICE describes energy management for ME/CFS as a strategy led by you, covering mental, physical, emotional and social activity. It says each person’s energy limit is different and changes, and that people are the experts in judging their own limits. [20] An app’s numbers can help you notice and plan. They shouldn’t overrule how you feel.

How did we choose these apps?

We picked apps that name ME/CFS or long COVID on their own listing or website, have a current US App Store listing, and offer a free plan or free app. We put Visible first because it is the specialist tool for heart-rate pacing.

Every fact about another app comes from its own website, help pages or store listing, checked on 6 October 2026. For Juno we used only what our own site says. This compares published features, prices and ratings. It is not a hands-on test of every paid plan, and no app here treats ME/CFS or long COVID.
