MVP development

- Background

Waveflow is a community-driven platform that helps people cultivate gratitude in their daily lives.

The company’s goal is to promote mindfulness, presence, and connection among its users through gratitude circles, both in-person and virtual, and a gratitude mobile app.

Waveflow’s Founder and CEO, Kyla Hilboldt, approached WeaveLines to help create an MVP version of the app, which would serve as a focused tool for gratitude journaling.

Scoping the MVP


The challenge for Waveflow was to develop an MVP that would effectively convey their unique value proposition to potential users.

The ideation phase required extensive efforts to identify the key features and functionalities that would support people in practicing gratitude every day.

The team needed to prioritize features that would differentiate their app from competitors and create a user experience that would be engaging and easy to navigate.

Product Discovery

Our team of experts followed a structured approach to ensure that Waveflow’s app was user-friendly and met their unique needs.

Through extensive research and analysis, we were able to ideate and create a prototype, which was then evaluated and refined to ensure the final product was optimized for a seamless user experience.

Included in this phase

  • Research.

    We began by conducting extensive research on gratitude journaling apps to understand the current market landscape. We also conducted user research to understand the target audience's needs and pain points.

  • Analysis.

    Based on the research findings, our team analyzed the data to identify key trends and user insights that could inform the development of Waveflow's unique value proposition.

  • Ideation.

    Our team then engaged in brainstorming sessions to generate ideas for Waveflow's features and functionality. We worked closely with Waveflow's team to ensure that the ideation process aligned with their vision and goals.

  • Prototype.

    Once we had a solid idea of the features and functionality, we moved on to creating a prototype. This involved designing wireframes and user flows to visualize the app's user interface and experience.

  • Evaluation.

    Finally, we conducted usability testing and gathered feedback from beta testers to evaluate the app's overall performance and user satisfaction. Based on the feedback, we made necessary changes and improvements as needed to ensure success.


Defining the taget audience

User Personas

WeaveLines conducted comprehensive research to understand the preferences and needs of Waveflow’s target audience.

Our team developed detailed user personas based on the research insights, providing valuable information about user demographics, behavior, and motivation. The user personas we created helped us to design an app with a user-centered approach that resonates with the intended audience, ultimately driving engagement with the app.


Mapping user journeys


During the wireframing phase of the Waveflow app, our team used Sketch for design and InVision for prototyping.

The primary objective of this phase was to validate user journeys and refine the MVP scope.

This process helped us to visualize the app’s structure and flow, test its usability, and make necessary adjustments before moving to the next phase of development.


Crafting the look and feel of the app


WeaveLines created a distinctive and memorable brand for Waveflow by designing a unique logo and applying it to the app’s wireframes.

  • The logo.

    The logo is simple, minimalist, and elegant.

  • The sun.

    The sun symbolism represents life, energy, positivity, clarity, confidence, and more.

  • The waves.

    The waves logo design represents an influx of fresh ideas.


Crafting a consistent and intuitive User Interface

UI Design

We applied the Waveflow branding to our wireframes, creating a polished and visually appealing UI design. Our team selected color schemes, typography, and graphics that aligned with the app’s brand identity.

With Sketch for design and Invision for prototyping, we created interactive prototypes, allowing the client to experience the app’s look and feel. This approach helped us to refine the design and ensure that it met the client’s expectations.


Bringing Waveflow to every hand

Mobile App Development

React Native with Expo was our chosen framework for the Waveflow mobile app, allowing us to seamlessly launch on both iOS and Android platforms. The benefits of using React Native with Expo include:

  • Cross-Platform Compatibility.

    One codebase serves both iOS and Android, ensuring consistency and reducing development time.

  • Rapid Development & Iteration.

    Expo provides a suite of tools that streamline the app development process, allowing for quicker testing and deployment.

  • Community Support.

    With a vast community of developers, solutions and updates are readily available, ensuring the app remains cutting-edge.

  • Enhanced Reliability with TypeScript.

    By integrating TypeScript, we ensured a more reliable codebase, catching potential issues early and improving code readability.

A robust and scalable backend solution

Backend Development

For the backend of Waveflow, we opted for Nest.js, enhanced with the power of GraphQL for data management and retrieval. Our choice was influenced by the following advantages:

  • Modularity.

    Nest.js offers a modular architecture that allows for easy organization and scalability as Waveflow grows.

  • Versatility.

    It integrates seamlessly with various libraries, ensuring flexibility in our development process.

  • Developer Productivity.

    Nest.js provides tools and features that streamline the development process, allowing our team to build more efficiently.

  • Optimized Data Fetching with GraphQL.

    GraphQL ensures efficient data retrieval, fetching only the data the app needs. This results in faster load times and a smoother user experience, while also offering flexibility in data requests.
