Majority of low-income families access the internet through their smartphones. Mobile developers have the opportunity to reach marginalized communities through their smart phones and create tools to benefit these communities. I will talk about how developers (especially underrepresented developers) have created mobile tools for problems within our communities. I will discuss my app, We Read Too, as well as other mobile apps like Tala. My talk will also be a call-to-action to mobile developers to reach out and work with communities that could use mobile tools to make their lives better or provide them access to resources.
