Manifest App

Product design

Content managing

As the lead Product Designer for Manifest App, an affirmations-based mobile application, I played a key role overcoming challenges and driving its success. To address insufficient conversion rates and low long-term retention, I conducted extensive research, including in-depth user interviews and Product-Market Fit (PMF) research involving 800+ users. This research laid out the foundation for a comprehensive product plan. 

With a cross-functional team, I led the planning and implementation process, leveraging data analysis from Amplitude and PMF Survey results. Through key hypotheses, we achieved game-changing results, increasing the onboarding conversion rate and paid subscriptions by 170%. 

In addition, I supervised the creation of compelling content for the app. By identifying popular categories and leveraging user insights, I ensured the app deeply resonates with the target audience. As the lead designer, I also mentored and supervised junior designers, enabling their growth and contributing to the team's success. 

Working on Manifest App taught me the power of leveraging data and purpose to drive organizational transformation. Through meaningful insights, I showcased the pivotal role a designer can play in achieving remarkable results and positively impacting user experience.

To the next project

Let’s create together!
