Creating Personas

I - Quantitative metrics from our user's behaviours

We leveraged user and purchase data we had, by December 2022, to guide features and shape a vision tailored to similar profiles, while creating personas to understand current users and assess their potential to convert from free to paying customers.

71,377

iOs App* downloads solely from the United States of America (who are also 74% of our total buyers).

19%

of the iOs total annual downloads in 2022 was Christmas-time, followed by 7.5% for Black Friday.

*The Android App was only launched in February 2023.

II - Out of the box customer insights

Customer service offered valuable insights into our personas through direct user interactions.

Interesting Fact

These watch bands are frequently bought by parents for their children.

Analysis

A portion of our target audience falls below the age data we can legally collect, as users must be over 13 to use the app or shop online.

Additionally

Parents reached out to share their kids’ experiences, request new collections, and ask about app features.

Strategic Approach

To validate our ideas before investing in a full redesign AND introduction of new features, we did the following:

I - Market and seasonal research:

Analyzed competitors' sales models (subscriptions vs one-offs)

Identified download trends from app stores and shopify to plan when to launch collection

Data and insight were used to shape content themes and push notifications

II - Testing two new monetization models*

In-app purchases for digital watch face bundles (iOs and Android)

Weekly subscription to time-limited collections tied to holidays and fan events (iOs)

*Teasers of features adapted to the new UI I designed

III - KPIs and insights

Conversion Rate: number of new subscriptions and sale after each release

Subscription Engagement: with weekly content (activation, cancellations, renewals)

User Segmentation: Free-only, Paid-only, Transitioned users from free to paid

Quick Measurable Success

Even though the new UI never saw the day on Google Play and the Apple Store we were able to know that our approach towards monetization was on the right path.

Features that were added to the legacy app gave us the following data and numbers

In-App purchase collections

13%

of our users have purchased at least 1 in-app collection

$44,700

generated from sold collections between
11/2022 - 11/2023

generated from sold collections between 11/2022 - 11/2023

Weekly Subscription
(Launched October 1st)

65

(14%) organic individual acquired subscriptions in the first month post-launch

$165.17

has been generated organically in the first 2 months post-launch

Seeing users engage with in-app purchases inspired several new feature ideas that, while never tested, we believe would have resonated well with our audience:

Bundle of collections from the same umbrella brand. Think everything under the DC Universe in one big collection of collections!

Premium subscription for users that will exclusive collections to brands they are fan of and that free users on the app will not even know about them

“Time-bomb” products like limited-time or limited-quantity watch faces, paired with previews of upcoming drops to build anticipation.

A basic design system was created for this project, but I build robust, documented systems. I’ll add a project showcasing that to my portfolio soon.
