How can you build a WhiteHat Jr. like app?

If all those figures have charged you enough to learn how to develop WhiteHat Jr. like application, here is a quick guide for whitehat jr app development cost.

Plan the business monetization model

Every business needs money to sustain itself; an app like WhiteHat Jr. is no exception. You can start planning how to build the app by considering the revenue model first. Here are some plausible monetization models suitable to this kind of app:

business monetization model of whitehat jr app

Paid membership

You can offer monthly or yearly paid subscriptions to the users. After a free trial class, the users need to pay a subscription fee to unlock all features, classes, and courses included in the app. WhiteHat Jr. differentiates various plans based on the number of classes included. You can also think on similar lines while planning a launch of the app.

Affiliate Model

In this business model, the app ties up with the books and other tools providers. The learner will require these free resources to complete the course provided by the app. So, when the user purchases any of these resources, the app gets paid an affiliate fee.

Paid certificates

In this earnings model, the app will provide the paid certificates on completion of the course. The apps partner with the reputed institutes or universities to use their brand’s name on the certificate. Users like to go for these certificates to color their resumes with something beneficial for their careers.

In-app advertisements and purchases

You may offer free registration to the app users. However, the app may be used as an advertising space. Businesses can pay the app for displaying their ads. The app can also offer certain features possible to use only on the payment of a fee. 

If you are a user of an OTT platform, you can understand this model much easier. Some OTTs offer movies or shows for viewing only on payment of a subscription amount. This is how you can plan the revenue generation model for your business app to make it an income source.

These are some of the target audience’s features of WhiteHat Jr. If you are planning to develop its clone, you must assess your audience on the above-mentioned points.

You may need people who are conversant with technologies that help accomplish faster-to-market rollouts.

While planning to recruit the development experts, the users can give a proficiency test. They can further probe the experts’ knowledge and expertise by designing a questionnaire. Also, a small development or testing-related assignment can be given to check the candidate’s comfort level with the process.
