Depends on the app features you want to develop:
If you want to learn how Kuika works and create a Web/Mobile (Native Android only) application, you can get started with the STARTER package for free.
If you want to develop Web/Mobile (including Native Android and Native iOS) apps that one/Many departments or end users can use, PRO is probably best for you.
You should choose the ENTERPRISE subscription package to create an application portfolio, have enterprise-scale features, and move your institution to digital.
