iPad and iPhone app product design


Snowflakes is the first app from my start-up, Hado Labs. The app is sort of like digital stamp art. It allows users to create art by tap, with custom background and color options. There are two modes; single which displays an isolated snowflake with over 9,000 shape combinations; and multi mode where you can layer different colored, and shaped snowflakes. Creations are saved to your photos and can be shared from the app via email, Facebook and Twitter.


Catherine is talented, extremely motivated,
and a pleasure to work with. She is always coming up with great new ideas and designs.

My Roles


Tools Used

Hado Labs team



To start, I researched the app market. I looked at reviews in the app store, posted online, and recommendations from friends. I evaluated their success with analytics from appannie. I downloaded dozens of apps, took screen grabs, and made notes of inspirational interfaces.

I worked closely with my developer to understand the constraints and resources we had available. Because of my background in design education, and the success with my earlier kaleidoscope app Annamika our focus was on creative apps. I came up with at least a dozen concepts. We decided to create Snowflakes first.

I used Photoshop to create high-fidelity wireframes and AppCooker to create a prototype of my vision.

For simplicity, I followed the iOS Human Interface Guidelines and used the standard design patterns created by Apple. I also created custom icons.

Once the framework was established, I created all the necessary assets in Photoshop. This included icons, illustrations, backgrounds, and loading screens.

I conducted a small focus group with moderated usability testing. From my findings the bugs were fixed, and I refined the user experience.



We started our project in September and launched 6 weeks later. We created two separate versions of the app, one for iPhone, and one for the iPad. Collectively we had thousands of downloads. A few months after Snowflakes, we released a separate app on the same engine called Hearts. The process itself was invaluable to transitioning my industrial product design knowledge into useful digital products.
