INTRODUCTION

Send Anywhere

Redesign

Send Anywhere is a file sharing application that takes an easy, quick, and unlimited approach to file sharing. Cloud sharing or storage services often offer a promise of unlimited file storing and sharing but their speeds and usability is compromised. Send Anywhere is for anyone wanting to share quality content, quickly, for free, from any device to anyone in the world.

Effort to Chunk

3. Unexpected event

Extra Eye Movement

When the user try to type the code,

the bar goes up and pops up ad instead
