I disliked the work flow to make a call in Windows Phone 8 (too many buttons to press navigating from the address book to the dialer, or to add a new contact).
How it works
It adds the T9 feature to a custom dialer, automatically recognizing known numbers showing the name of the contact mathing or allowing to add the new number to a new contact with a single step.
Challenges I ran into
To develop my first app for Windows Phone 8.
Accomplishments that I'm proud of
I was able to implement the T9 and to make a dialer faster and smarter than the native one.
What I learned
To develop a Windows Phone 8 app.
What's next for Turbo Call
It will be provided with customizable dialer and calls history.
