When choosing a tech stack for your mobile app, consider the user base, budget, timing, functionality, and expansion of the technology stack. A suitable tech stack should allow you to build an app that meets the needs of its target audience while also being cost-effective and scalable. You may want to consider no-code tools like Bubble, which offers a full-stack product development platform, or traditional technologies such as React Native or Flutter for cross-platform development. Additionally, consider tools like Google Analytics, PostHog, Postman, Zapier, Stripe, Usersnap, Mixpanel, Median, and other integrations that can help you understand your app's performance, analyze user behavior, test APIs, automate workflows, manage payments, collect user feedback, and monitor user retention. By choosing the right tech stack, you can build a robust and scalable mobile app that meets the needs of its users while also being efficient to develop and maintain.
