Humin: the iPhone app that ensures you never forget a name
A new app called Humin that remembers relationships and shows you the people that matter in any given situation could replace the iPhone's native Phone app
Humin, an app that reorganises the contacts on your iPhone based on 'human' factors such as relationships, location and time, is launching on the US App Store today, promising to replace the default phone app.
Humin works by cross-referencing data from the various apps residing on your phone – such as email, calendar, phone contacts, Facebook and LinkedIn – to bring context to your contacts list.
This means that, rather than having to remember contacts' names, users can search the way they think, using terms like "met last week", "lives in London" or "friends with Susan".
Humin can also identify which people are most relevant in a particular context, such as the person in your next meeting or your friend that is visiting town, and display them first.
“The goal is to remember someone the way you do,” Ankur Jain, Humin’s chief executive, told Bloomberg Businessweek.
The app is already being tested by 20,000 people, including Virgin head Richard Branson, will.i.am of the Black Eyed Peas, Angry Birds creator Peter Vesterbacka, and the US Chamber of Commerce.
Shakil Khan, head of special projects at Spotify said: “It’s changed how I make calls. I don’t have some Adam or Aaron at the top of the list who I haven’t seen in years.”
Humin is currently only available in the US, and only on iPhone, but Jain plans to launch in other countries over time – with a UK launch coming soon – and also plans to expand to Android.
The company said that it will never share or sell users' contact information, and all passwords are processed locally on the user's device, meaning that no sensitive information is stored in the cloud.
This is not the first attempt to replace the traditional alphabetised contact list on mobile phones.
LinkedIn, for example, recently launched a stand alone Contacts app, which is designed to act as a quick-reference directory for LinkedIn users, bringing together their address books, emails and calendars in one place.
Other previous efforts at smart address book apps include Addappt and Brewster.
