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 y el privacy notice.
If you already own the domain, review how to prepare a transfer. For help choosing a name, read our practical guide.
