■ Developer Message

Tongda is an app created by a developer who has long struggled with pain due to a herniated disc. It was developed to address the challenges of verbalizing pain, the inability to accurately communicate symptoms in hospital settings, and the frustration of not being able to remember which treatments were effective.

We hope Tongda will be helpful to those who are experiencing similar pain on their pain management journey.
