We've been covering African and diaspora tech for years at OkayAfrica and it only seems to get more exciting every year. Young African developers both on and off the continent continue to adapt to the times, designing and building new apps, online businesses and unique pieces of hardware for a wide range of uniquely African experiences.

For Silicon Africa month, we've taken a look back at seven tech stories that have brought us here. Here are some of our favorites:

Tress

Tress, is a mobile app that helps black women around the world find hair inspiration, and high quality stylists and products. It was founded by three female software entrepreneurs from Ghana and Nigeria—Priscilla Hazel, Esther Olatunde and Cassandra Sarfo.

AfroEmoji

The world communicates through emojis, digital stickers inserted into texts and chats. Africans deserve these visual symbols to reflect their own reality. This is the view of AfroEmoji boss Ayoola Daramola who has created pan-African emojis for you to use in your smartphone conversations.

“Mobile is king in Africa/Globally—it is the tool for communication and media consumption, so we expect the Afro Emoji to become a key component in how Africans message and chat, in much the same way as emoji Stickers have become so popular in the East & West."

Look Up

Ekene Ijeoma has created an app for the walking internet browser—those of you fiddling on your phone as you walk down the busy sidewalk. Look Up uses GPS to detect when you're near an intersection and give you an alert—vibrations and an eyeball animation to tell you to look up before crossing the street. But more than just a useful safety app, Ijeoma has suffused it with an artistic purpose.

Teemoji

Teemoji allows users to express themselves using custom Toyin Aimakhu inspired images and Yoruba sayings. Check out more here:
