WhenWho WhenWho v1.0

Download WhenWho

WhenWho is the first mobile app that predicts your forthcoming calls using a lightweight but performant predictive model.

WhenWho is the next revolution in mobile predictive analytics. It gives you a clear insight of your upcoming call activities. WhenWho helps you discovering the hidden patterns behind your incoming and outgoing call. WhenWho helps you responding to the following questions (and even more):

Who is gonna call you in the upcoming period
What are the odds that a given contact calls you now
When will be the next call of a given contact
How often a contact calls you
Who should have called me

WhenWho responds to those questions and generate predictions for calls in both ways:
Incoming calls : to bring you all the knowledge you need about your future incoming calls which gives you the control and limits the element of surprise
Outgoing calls : to give you an incredible insight of your call activity and habits.
If you are indifferent about who is calling who you can analyse data using the conversation menu.

WhenWho is an accurate predictive application. Meanwhile, it has a small foot print and all the processing is easily handled by any mobile phone.

WhenWho uses the data that is already in your android call logs. Consequently, WhenWho doesn't need too much space to save data. In fact, no calls are saved by the app, just the predictions to present to you are saved. Even then you have all the control over the reports that are shown to you and you can erase from your phone any contact that you don't want to analyse.

If you are satisfied with WhenWho, you can easily migrate towards the paid app which gives you more accurate predictions, great performances and is obviously ad-free. The paid version will be released soon after a final test and improvement phase.
