Support

We usually reply within a few business days.

For questions, bug reports or content corrections, email sidtchang@gmail.com. To report an error in a specific topic, the quickest way is the Feedback on this topic box at the bottom of that topic in the app, because it tells us exactly which topic and content version you were viewing.

Frequently asked questions

Does the app work without an internet connection?

Yes. All content is stored on your device, so search and every topic work offline. Sending feedback is the only feature that needs a connection.

How is the content kept up to date?

The content is written and reviewed by the editor and updated through app updates. The content version is shown on the About screen. Keep automatic updates on to get the latest content.

I found an outdated dose or a mistake. What should I do?

Use the feedback box at the bottom of that topic, or email us. Please do not include any patient information.

Where are my saved topics stored?

Only on your device. We don't have accounts, so saved topics don't sync between devices and are removed if you delete the app.

The feedback form says "Not sent." What now?

Check your internet connection and try again. You can also tap "Email it instead" to send the same message from your email app.
