Banks and traditional financial institutions are facing significant challenges in the digital finance world, with fintechs growing rapidly and gaining popularity. The mobile revolution has completely redefined banking habits, with online transactions now preferred over traditional methods. Fintech competitors have eclipsed traditional banks in mobile app user growth, with a 337% increase between 2020 and 2021. These newer fintechs are attaining higher rates of user satisfaction, releasing updates nearly twice as often as older banking institutions. The cost of competition for traditional financial institutions is steep, with up to 40% of bank revenues at risk by 2025. To cope, banks must understand why fintech apps are flourishing and improve their mobile performance, which is critical to maintaining app users and positive ratings. Improving an app store rating requires a comprehensive approach focused on enhancing app quality, with six key principles: testing, user feedback, stability, monitoring, security, and development. Robust tools capable of detecting performance anomalies can help achieve perfection, and investing in app performance tools is the fastest way to make progress toward improving app quality and overall ratings.
