Review

We needed a reliable partner to handle quality testing for our iOS and Android applications, resolve bugs, and enhance features based on user input. DeviQA now supports three of our apps - two available on both iOS and Android, and one exclusively on Android. They ensure release candidates are rigorously tested and work closely with our development team to identify and resolve issues efficiently. In addition to QA, DeviQA oversees App Store and Play Store reviews, helping respond to user feedback and complaints. Their efforts have significantly improved the functionality of our apps, leading to increased stability and reliability. Users frequently praise the apps’ performance, and their consistently high ratings in the App and Play Stores are a direct result of DeviQA’s involvement. The team’s work ethic and expertise stand out. The two resources assigned to our projects have a deep understanding of our systems and processes, resulting in a smoother workflow and enhanced productivity. Their contributions have been instrumental in achieving our goals.
