Challenge

Looking for experienced mobile app development services, the Customer turned to ScienceSoft and requested development of an offline Music Store for mobile phones. The store had to be different from many analogues: its unique feature should be provision of previews for audio tracks that could be bought afterwards.

Solution

ScienceSoft designed and developed an app that allows users to listen to the track before buying it as a ring-tone or a full version. The pre-listening is organized in a safe way which means that the application downloads the tracks to the secure Java storage from which they are not reachable for other purposes but for the use by the application.

As a JAVA application, Music Store provides user-friendly look-and-feel with highly customized design and convenient controls.

Music Store also provides user commercial information which is received from server, e.g. colorful promo banners, server alerts and browser links. Music Store is eligible for offline launch (user can browse the once loaded catalogs offline); it can maintain frequent connections via HTTP with server-side service engine, which controls the client's behavior in many ways.

Results

The result of the joint work of the Customer and ScienceSoft was a successful delivery of the product suite to operators and embed it for more than 100 java handsets. There was wide range of phone models, which contain this service: SonyEricsson, Sagem, LG, Motorola, Samsung, Nokia, etc. There is hundred thousand activations all over the world.
