It was really a great challenge. Got good practice. And I am getting 2-3 case studies out of it. Thnx Mastry team, Rohan, Rakshita & Himanshu. Not just this but all 3 challenges were just amazing.

My learning experience has been excellent. I’ve learned how to confidently explain UI changes to leads, stakeholders, or clients by connecting them directly to user needs and product benefits. I also learned the complete process of following heuristic principles, evaluating a product step by step, and running usability testing with real users. Most importantly, I now know how to present these findings clearly in a case study.

The community experience was great too; very interactive, supportive, and helpful in guiding me to do each task the right way.

This is my 4th challenge with Mastry, and it’s honestly been such a learning curve, in the best way possible. I can feel how much more confident I’ve become compared to when I first started. The live classes, the community sessions, and that little dopamine rush after submitting assignments on time… it all just keeps you going.

Huge thanks to the Mastry team, Rohan, Rakshita, and Himanshu, for putting together yet another amazing challenge. I’m genuinely excited for what’s next and can’t wait for more.

It was a great experience. This is my second challenge with Mastry. Got a clear road map to go through the redesign process. Now ask me all 10 heuristics in the middle of the night, I can tell it😂. The UX Audit has helped me understand the gaps in a design very conveniently. I got the opportunity to conduct Usability testing, which made one thing clear: 'Each user is different, their thought process is different.'

Coming to redesign, the weekend class was more effective for me, getting it cleared from Rohan that changing the look is not important, solving the problem is.

I used to struggle with the first case study that I had worked on; maybe it had taken a month or so. Got the reality check that I will have to work on it again 😫, because now I know what needs to be done, the story that needs to be told to the reader. Having completed 7 case studies in a week, case studies that make sense, that solve problems clearly, makes me proud of myself.

Thank you, Mastry team, for coming up with this challenge. Looking forward to more pocket-friendly challenges that help shape better designers and allow indulging in challenges to get rid of laziness, to polish, and get a better version of yourself.

This App redesign challenge has helped me a lot. It has helped me understand users more clearly. When I undertook this challenge, others shared useful resources, which gave me a clearer understanding of what app redesign entails in the real world. This experience has given me the confidence to understand and work on the app redesign from the user perspective. Thank you, Rohan and their entire team, for the complete support.

1. This is my first time joining this community and I will say It's was a great experience.
2. UX Audit, Usability testing and how to make case studies.
3. Very nice.
4. Learning is easy, language is clear and easy to understand.

My Experience is very good as i got to learn how to think of a product where the user is facing issue and able to redesign according to the user needs. Regular task helped me to understand this process Thanks to @Rohan @Rakshitha and @himanshu for constant support

Great

This 21-day App Redesign Challenge has been a truly transformative experience for me. Before starting, I had little understanding of how to conduct a UX audit or usability testing properly, or how to use those insights to improve designs and user flow for better usability and accessibility. But throughout this journey, I learned more than I ever expected.

Learning from Rohan and the entire Mastry team was not only educational but genuinely inspiring. Each day was thoughtfully structured so that everyone could learn something new, and the learning sessions were incredible. During the sessions, I cleared all my doubts about usability testing and redesign.

A very special thanks to Himanshu bhai. He was a true gem throughout all three challenges, including the UI and UX audit challenges. Whenever I had a doubt, no matter the time, day or night, he supported me without hesitation. His guidance made a huge difference in my learning.

I truly consider myself lucky to have learned from Rohan and the Mastry team. I’ve gained so much knowledge about UI and UX. Thank you to the entire Mastry team for creating such an amazing challenge, one that taught me more than a full UX/UI bootcamp ever could.

This 21-Day Redesign Challenge was fantastic! I truly appreciate the structure and drive provided by the Mastry team.

My biggest takeaways were:

Challenging Assumptions: I learned to move past the idea that certain design mistakes were "useless." The hands-on audit process showed me the true impact of errors, forcing a deeper, more empathetic approach to UX.

Building Consistency: The competitive ranking and rewards were a brilliant motivator! They taught me how to effectively manage consistency in quality design work, even while balancing a full-time job.

Process Mastery: The weekly structure—diving into Audits (Week 1), then structuring data with Excel (Week 2), and finally synthesizing into a Report (Week 3)—provided a clear and complete step-by-step framework for real-world redesign projects.

Thank you for organizing such a valuable and inspiring challenge!
