App Development
NIDDO APP
NIDDO is a mobile app designed to help separated parents manage aspects of co-parenting in one place. As the product designer, I designed the app's screens and collaborated with the founding and technical teams to refine the experience, validate functionality and prioritise product improvements.

Discovery & key challenge: understanding users
Listening to users to identify friction
We gathered feedback through direct messages on social media and user surveys. Parents shared features they found confusing, issues they encountered and improvements they wanted to see.
I used this feedback to identify areas where the product experience needed to be clearer, particularly in messaging and navigation.
Rather than relying only on assumptions, I considered users' questions and reported difficulties when reviewing the experience.
—————————————————————
Making messaging easier to understand
The challenge
The messaging feature included too many subcategories and message types, making it difficult for users to understand which option to choose.
My approach
I reviewed the existing structure and helped rethink how messages were grouped. We simplified the categories into broader, clearer options to reduce unnecessary complexity and make the feature easier to navigate.
The outcome
The revised structure was better received in subsequent user feedback. This reinforced the importance of using clear, familiar categories rather than exposing users to unnecessary complexity.
Key learning
More options do not necessarily create a better experience. Clear information architecture helps users understand what to do and make decisions with less friction.
—————————————————————
Making everyday tasks more intuitive
I also reviewed navigation flows for features such as the calendar and expenses.
Based on user feedback and the issues we identified, we adjusted parts of these flows to make the available actions and information easier to understand.
I worked on refining the user journeys and interface so that key tasks felt clearer and more straightforward, while coordinating with the technical team to review functionality and implement improvements.
—————————————————————
Focusing on the features that added value
As the product evolved, I collaborated with the team to review feature relevance, usage and overall product coherence.
One example was the community feature. We identified that users did not fully understand its purpose and that it did not fit naturally with the app's core functionality. The team decided to remove it and focus on features that better supported parents' everyday needs.
This experience taught me to look beyond individual features and consider how each one contributes to the overall product experience.
Testing, iteration & launch
Before and after the app launch, I carried out performance testing and stayed close to user feedback to identify issues and opportunities for improvement.
I collaborated with the technical team through regular meetings to review feedback, prioritise fixes and improvements, and refine the product across successive releases.
Although the developer handled the app's publication, I contributed to the preparation and ongoing improvement of the product experience by reviewing functionality and supporting iterative updates.
—————————————————————
Monitoring product performance
I reviewed available product metrics alongside user feedback to help the team understand the app's performance and identify areas for improvement.
This included monitoring downloads, active users, store ratings and technical stability through the available app-store reporting tools. These signals complemented qualitative feedback when discussing priorities with the team.
My focus was to connect what we observed in the product with practical next steps for improving the experience.
Outcomes & Key learnings
What I contributed
Designed the app's screens and refined key user flows.
Simplified the messaging structure in response to user confusion.
Improved navigation across calendar and expenses features.
Contributed to feature prioritisation by considering user understanding, usage and product coherence.
Supported iterative improvements through performance testing, user feedback and collaboration with developers.
What I learned
Designing a digital product is not just about creating interfaces. It also means listening to users, challenging existing assumptions, making trade-offs and working closely with developers to deliver a coherent experience over time.
