OceanCaller

The first decentralised Caller Id app.

Identify unknown numbers, spam, or companies calling numbers.

Centralized apps like truecaller help us get the owner of unknown mobile numbers. They do it by collecting contacts of people who have there apps installed, and then the apps serves the information to the one who requires this information

But in this case the data published gets no benifit as well as the collected data gets shared with everyone hence hampering privacy.

Our mobile app

Welcome screens

User can import his wallet with his private key

App will read all his contacts and create a data set from it to publish on ocean marketplace. If another user buys his dataset then publisher will be rewarded.

Now if someone wants to search for unknown spam calls, he can search the phone number in dataset.

In future We will also be adding a Mark as Spam option for spammers on the mobile app and when the user has got a significantly collected data then he can publish this dataset too for others to buy and improve their experience with spam calls by purchasing these datasets to oceancaller.
