SickSlip is an online service that connects people seeking absence documentation with a physician for a medical evaluation. Customers complete a short intake describing their situation, and Dr. Adam Z.

Notes are designed for work or school absences and may address situations such as illness, travel, jury duty, or a mental-health day. Each note includes a QR code and unique document ID so employers or schools can verify its authenticity, while medical details remain private. SickSlip charges a flat $29.
