Frequently asked
What is the best way to track Long COVID?
Keep it low-effort and consistent: a daily energy/symptom rating, crash flags, and voice notes on hard days. Consistency matters more than detail.
How do I track post-exertional malaise (PEM)?
Flag crash days and log activity. Over time you can see whether crashes tend to follow higher-activity days.
The calm way to do all of this
The Good Tracker is a voice-first symptom tracker built for exactly this: log how you feel in seconds (talk, tap a slider, or snap a photo), then see what helps and what hurts over time.
