Mobile Google Contacts Alternative

For some reason, Google doesn't offer a mobile interface for Google Contacts. Sure, you can use the autocomplete feature from Gmail to find an email address or sync your contacts using CardDav or Exchange, but there's no mobile app for Google Contacts.

I've tried to use the standard desktop interface available at google.com/contacts, but it's slow and hard to use on a mobile phone. Fortunately, Google still offers the old version of the Google Contacts site at google.com/contacts_v1 and it works a lot better on a smartphone.

Update: There's another option - https://mail.google.com/mail/h/?v=cl (thanks, Alexandre).
