Start with Local
Use Free Local when you want one-device symptom logging, rescue inhaler logging, medication routine tracking, user-entered peak flow or pulse ox records, and a basic 30-day review after sign-in without checkout.
Add Plus for a 90-day window
Plus is the practical step when you want a 90-day history/trend window, Cloud Backup & Sync when enabled and eligible, and no mobile banner ads, but do not need Premium reports, Premium insights, pollen detail, or 180-day and 365-day review ranges.
Choose Premium for the bigger picture
Premium includes Plus and is the natural upgrade when you want cloud backup/sync when enabled and eligible, 90-day, 180-day, and 365-day review ranges, compare periods, richer reports, Google Pollen detail when available, and more complete pattern review while keeping claims cautious.
Use Care Access when invited
Care Access is the discounted full-feature Premium-level partner path for participating clinics, groups, employers, schools, or organizations. It includes Cloud Backup & Sync when enabled and eligible and is not sold through public checkout.
