When should you choose .app?
.app can bring together an app’s introduction, instructions and sign-in page. A short address is useful on small screens and in promotional materials.
A practical example
For a mobile app, keep FAQs, a privacy policy and official app store links on your website so users can verify they are downloading the right application.
Before you register
.app uses HSTS preloading: set up a valid HTTPS certificate before publishing. Domain registration alone does not include hosting, development or a configured certificate.
Before confirming registration
A search does not reserve a name. Check spelling, registrant details and the registration period. Registration is confirmed when the provider completes the operation. Read the terms of service and the privacy notice.
If you already own the domain, review how to prepare a transfer. For help choosing a name, read our practical guide.
