What should a Long COVID symptom tracker cover?
Long COVID can involve many symptoms that change week to week, so most trackers let you pick your own list and rate how strong each one is. Many people also log energy, sleep, food and medications, and mark crash days. Our guide on how to track Long COVID symptoms walks through a simple setup.
Do I need a wearable?
No. Long COVID Companion, Elara and The Good Tracker all work without one 147. Visible's free app uses your phone camera for a morning reading, and its band adds live pacing alerts 56. If post-exertional malaise is part of your picture, see how to track PEM.
Which apps let me log by voice?
Long COVID Companion has a voice diary: you record how you feel and can play it back later 4. In The Good Tracker, a voice note becomes that day's scores and notes, so you don't have to fill in a form afterwards 1. We didn't find voice logging stated for Visible or Elara 57.
Where does The Good Tracker fit?
GT is for people who want one low-effort log. You just say how you feel, and it keeps symptoms, food and meds on the same day 1, so you can see how they line up over time and bring a clear summary to your appointment. It doesn't read wearables, and it runs in your phone's browser until the iOS app arrives. More on our Long COVID symptom tracker page 3.
Who should choose which?
Long COVID Companion may suit you if: you want a free tracker made for Long COVID, with a broad symptom list, questionnaires and links to care networks (many in French) 4.
Visible may suit you if: you want heart-rate pacing and will wear a band (band features are US and UK only 5).
Elara may suit you if: you want a free pacing diary that brings in watch data, on iOS or Android now.
The Good Tracker may suit you if: talking is easier than tapping and you want food and meds next to symptoms. It isn't the right fit if you need wearable heart-rate pacing or a native app today.
