GOOD TO KNOW

A few useful answers.

Where do I use Chat?

In the iPhone, Mac or Android app. The website is for discovering cases, downloading the apps, creating your account and managing Pro.

What counts as one question?

A new question and each follow-up count separately. Free accounts receive 30 questions each month; Pro removes this question limit.

Can I keep my existing account?

Yes. Sign in with your existing username and password. If your Google email already belongs to an account, sign in to that account first, then link Google so your existing membership stays with you.

Do I need Pro to read the archives?

No. Free accounts can search and read the complete archives in the apps. Each blog also publishes its latest 300 cases for anyone to read without signing in.

How do I manage a subscription?

For a subscription purchased on this website, use your account’s subscription page. If you subscribed through Apple, manage renewal in your Apple account.
