The facility is an offline Yellow Page, which is expected to bring about a meaningful difference to the way information is accessed and the consumer buying behaviour gets influenced, especially with many smartphone users in the city, he said.
Stating that search categories in the application include emergency services, classified, tourist and entertainment places, company listings, helpline and brands, he said the app allows to make direct calls, send SMS, e-mail, visit prospective sellers' website and view maps for location.
Once downloaded using Internet, it works without GPRS/3G connection and does not need a network connection as it enables people to carry mobile business directory on their phone free of cost, Chari said.
The company, which launched a facility in Dubai a fortnight ago, wants to make four lakh listings in another six months, and depending on the success, it would consider charging for the facility, he said.
With six lakh smartphones functioning in Coimbatore, Chari said the company plans to launch 'Call Bengaluru' next month.
