Challenge

Harp is an app that improves, mends, and jumpstarts relationships.

The client approached us with an idea to build a couples-oriented app on iOS that will have a scalable infrastructure and get users' attention from Day 1 after launch. Besides development, the client was interested in the design and GTM strategy.

Solution

1. Planning

Applica conducted competitor and category research to understand the best practices for features, content, and user flow. Based on that, Applica suggested the infrastructure and MVP version.

The app was built on Swift UI following the best practices or scalability since the dev team had to make sure that the app would function on a 5X, 10X, and 1000X user scale. Along with the development, Applica contributed to user-friendly design and product flows to ensure the leading product KPIs would perform according to benchmarks in the Tier 1 market.

2. Execution

Once the development stage was over, Applica supported the app after launch by building a convenient customer support system and product backlog.

Results

Applica has successfully launched the app for the client, who now sees excellent user metrics related to engagement, session duration, and daily activity.
