From the developer:
Hashr is a unique and innovative mobile application that can generate secure, unique, and theft-resistant passwords for every website. It creates highly secure and strong passwords for all the websites you log into and keeps them safely stored on your mobile device. The password generated by the app will never be stored on a server or somewhere else so you can have peace of mind that all your passwords are safe.
