DesignoQuiz – Full Application iOS Android Web


We chose React Native because first of all it’s developed and supported by Facebook, and is moreover used by them in their biggest products. Furthermore react native is built on top of JSX/Javascript which means we don’t have to use extra languages and avoid more headaches with switching things up. And lastly we want one codebase for every deployment type – so we have one source code and 3 different (major) channels including; Web, Android, iOS. The only thing we have done is distinguish some designs for each of those, so because Android has a different status bar to iOS, we’ve opted to have conditional styling so both operating systems look and function well with the app.


Why Node js, express, postgres (PERN stack)?


We’ve chosen node and express as the back-end due to it’s powerful middleware design, allowing us to dissect and organise routes as well as add middleware (conditional too!) to have powerful functionality, as well as being minimal by design. Postgres is also a good choice for this application because of its performance and capabilities. Express is good because it allows us to combine our middleware, controllers, routers and reduce coding/development time significantly.




The front-end (client) is the main app, which can be exported to web, ios and/or android. Using Expo we can easily deploy either as a full-apk, or a bundled (and more efficient) apk to release on the store.


The whole client is a single-page (SPA) too, which means better performance, more user-friendliness and fluid pages. Users will be playing on the client, with their progress, attempts, levels saved

while they are actively engaged in the app. The client will load data from the backend and respond accordingly. We feature adverts for Google Admob, which can be configured in the admin dashboard, among other things. Easily enable/disable adverts, change advert providers, ID, etc.
