    • Generating Ideas: Think carefully about the need for a language learning app before diving headfirst into app creation. The first step in developing an effective e-learning app is doing thorough research. After that, you may begin thinking about the e-learning app’s functionality, technological architecture, and other components.
    • App Platform: Several companies struggle when trying to design an educational app since they don’t know which platform is best. It is recommended that before beginning the development process, a specific development platform must be selected considering the target audience.
    • Tech Stack: Choose the technological stack in accordance with the app development platform you’ve decided on. Different platforms call for different solutions and technological stacks.
    • UI/UX: An uninstall will be the sole result of a poorly made e-learning application. If users have trouble navigating the app’s functions or find it unappealing, they will delete it. Thus, focus on making clear and engaging UI/UX.

    • QA: App development is not complete without app testing. Before releasing educational software in the market, it should be thoroughly tested to ensure that it is completely error and bug-free.
    • Launch: If you’ve followed the previous stages correctly, you’ll be ready for the last phase of your language learning app. Launching an app is only the first step in expanding your company.
