An iOS developer and marketer created a unique app in 2014 aimed at improving the quality of fake call prank applications available. The app allows users to simulate receiving calls from various characters, including celebrities and fictional characters. It features nine different call screens, the ability to record custom voice messages, and offers 99 ringtones. Since its launch, the app has amassed 799,804 installations and achieved notable user engagement, with a retention rate of 25% on day one and 8,609 monthly active users. The app operates with no ongoing costs aside from updates necessary for new iOS versions, as it uses a simple business model without a server backend. Revenue is generated through a combination of in-app purchases and video advertisements, with a free version contributing to its primary download figures. Despite this, there is room to enhance monetization strategies and increase revenue generation. There have been no significant marketing efforts beyond initial cross-promotions with other apps, and the app has organically grown. Reasons for selling include the desire to focus on other business ventures. Included in the sale are all code rights, photo licenses, and any relevant walkthrough materials. The app shows potential for further development through features such as a texting bot, celebrity licensing, and more engaging content, suggesting opportunities for increased user engagement and revenue.
