Client Reviews and References: Look for reviews and testimonials from previous clients. Positive feedback and successful project completions are good indicators of a reliable developer.

Post-Launch Support: Ensure the developer offers post-launch support for bug fixes, updates, and potential upgrades. An app requires continuous improvement and maintenance to stay relevant.
