Before launching an app in beta, ensure that it is stable enough for use, with critical issues or data loss absent, and core functionalities available. Prepare beta testing tools, on-boarding processes, documentation, a detailed test plan, a defined beta team, relevant metrics to track, and a clear understanding of the roles of each stakeholder. Align your beta testers with the goals of the test, ensure they are familiar with feedback channels and tools, and have signed non-disclosure agreements. Implement blogging and beta landing page strategies to recruit users and generate buzz around the app. Identify industry influencers to validate pricing and positioning before the actual launch.
