One thing I have learned from building products for users in Africa is that an application can work perfectly on a developer’s laptop and still fail badly in the real world. The engineer tests it with stable Wi-Fi. The API responds in milliseconds. Images load immediately. Forms submit without issues. Everything feels fast. Then the product reaches an actual user. They are connected through mobile data. Their network keeps switching between 3G, 4G, and nothing at all. They open a form, spend several minutes entering information, and tap submit.
The loading indicator appears. The request times out. The application clears the form. Their work is gone. From the developer’s side, this may look like a simple failed API request. From the user’s side, the product cannot be trusted. That difference matters.
I have seen development teams treat poor connectivity as something outside their control. They add an offline banner, increase the request timeout, and assume the problem has been handled. But telling someone that their internet is bad does not help them complete the task. The user already knows the network is bad. What they need is software that expects it.
A merchant should be able to record an order even when the network disappears. A field worker should be able to complete an inspection without waiting for the server. A driver should not lose a completed trip because one request failed. A user filling a long form should never have to start again because the connection dropped at the wrong moment.
