About this app

Track your thyroid health with ease – fully offline and private.

Papillon is a simple yet powerful app designed to help you log and track your thyroid lab test results over time. Whether you're managing hypothyroidism, hyperthyroidism, Hashimoto's, or other thyroid conditions, Papillon gives you the tools to understand your lab values and spot trends you can discuss with your doctor.

Key features:

Log and track your lab results (TSH, FT3, FT4, and more).

Visual percentage view of values for quick and easy interpretation.

Log the dose taken at the time of each lab result.

Offline-first: All data is stored locally on your phone — no internet needed, and your data stays private.

Export your data: Create and share CSV or PDF reports with your doctor or save them as backups.

Restore from backup: Easily import your past results via CSV.

Advanced filtering: View your data by date range, specific test, or custom filters.

Customizable test names: Rename existing tests or add new ones to fit your personal thyroid health journey.

Light & dark mode support for comfortable viewing at all times.

Smart suggestions when adding new entries — the app remembers your previous inputs (like date, test ranges, etc.) to speed up logging.
