Hi DoreenMichele, Thank you !! And I greet you for your self learning. Yes you are right, we are based in Tunisia. Really, we don't have a critical issues to access electricity compared to other african countries. With 50$ (120 Dt) in average, you can buy smartphone and tablets, most are chineese brands either with their names or under white labeled 'Tunisian' brands, and some known brands (huwaiey, sumsing, ZTE) that provide some low-cost of their products dedicated to developing countries. We first thought about tablets because it's provide large screen and they gave us the possibilities to develop the system. The smartphone is a great choice also but we need to adapt our apps in a responsive way so can be rendered in multiple screen sizes.
