EnvelopeOS
EnvelopeOS is a pacing planner for people with ME/CFS or long COVID, built around post-exertional malaise. It records what a day contained alongside how you were one and two days later, because that is where the cost of a day shows up. It sits alongside your specialist service, not in place of it.
Direct, no marketplace fee. A matching mini-planner is offered at checkout.

WHAT YOU GET
- Activity & Payback - One row per day. Fill in the top half on the day, then come back after 24 and 48 hours and complete the bottom half. That is the whole design.
- PEM Symptoms - Which symptoms came back, how strong, and when they started relative to what set them off. The delay is the defining feature, so it gets its own field.
- Medications - What you take, what each one is for, and what you noticed. Most of what is used here treats an individual symptom rather than the condition.
- Works fully offline. Nothing leaves your device. JSON export and import.
