In general, video games are considered to be dopamine-releasing products. When you're happy or excited, the chemical is released into your system. To make a non-gaming app more enticing to users, you must provide them with a cause to return and compete with one another regularly. Therefore, it is safe to assume that incorporating this experience into any of your applications makes them more joyful for your customers to use.
Having to rewrite your website or app is the least appealing aspect of this solution. The addition of gamification to your program does nothing to improve its performance; rather, it just enriches the user experience by making it more entertaining and rewarding for the user. The inclusion of gamification elements directly influences the number of downloads of an app.
