See which exertion comes before a crash, even days later. Pace within your energy envelope and build a dated record you can show your doctor. Built for ME/CFS.
Mya is built for people living with ME/CFS (myalgic encephalomyelitis / chronic fatigue syndrome).
Living with ME/CFS means unpredictable crashes, symptoms that shift day to day, and constantly having to prove you're not "just tired" to doctors, employers, and family. Mya fixes that.
Log your day in seconds
Rate your functional level on the Bell Disability Scale, track brain fog, and note how you're pacing. Built for days when even typing is hard.
Track Crashes, not "flares"
Post-Exertional Malaise (PEM), the delayed crash after physical, cognitive, emotional, or social exertion, is the hallmark of ME/CFS. Mya calls it what patients call it: a Crash. Log its severity, how long it lasted, and what may have triggered it.
Pace with your Energy Envelope
Rate available energy against expended energy each day, using Leonard Jason's Energy Envelope model, the pacing approach the ME/CFS community actually uses.
Get warned before you overspend
Mya watches for the early signals that tend to precede a crash: an overspent envelope, rising brain fog, a declining functional trend. Rest before you crash, not after.
Connect your health data
Sync with Apple Health to capture steps, sleep, heart rate, HRV, and active calories automatically. See how your body's signals line up with your symptoms.
Get AI powered insights
Mya looks at your logged symptoms and health data together and surfaces patterns you might miss
Take the DSQ-SF
Complete the DePaul Symptom Questionnaire, Short Form (DSQ-SF), the validated clinical instrument developed by Leonard A. Jason, PhD, used in ME/CFS research and diagnosis.
Track your medications
Log what you take, including as needed medications, with reminders so nothing gets missed.
Share evidence with your doctor
Generate a clean PDF summary of your Crashes, functional trend, and DSQ-SF results. Ready for the appointment where you have fifteen minutes to make months of symptoms count.
