The iOS app, a noise decibel meter, is a profitable and low-maintenance tool available on the App Store since 2024. Generating approximately $2,400 monthly in revenue, with around $1,500 net profit, it offers a viable investment at $21,000, priced at about 1.2 times the annual net profit. This utility app transforms iPhones into precise decibel meters, attracting a diverse user base from hobbyists to professionals, providing both free and premium features to enhance user experience and remove ads. The subscription-based monetization includes weekly, monthly, and lifetime options managed through a transfer-ready platform. The app benefits from consistent income, minimal maintenance, and automated paid acquisition campaigns. The independent developer and entrepreneur behind the app, based in Spain, has been responsible for its development and marketing strategies, ensuring stable performance but highlighting several untapped growth opportunities. These include optimizing the app store presence, revamping advertising strategies, enhancing user onboarding processes, and introducing new premium features to increase the lifetime value. Included in the sale are the app’s source code, all intellectual property rights, the transfer of the App Store listing, and the Adapty account along with subscriber data. The seller intends to focus on other business ventures and seeks a new owner who can actively exploit the app's potential for growth. A complete post-sale support package is offered to facilitate a seamless transition for the new owner, who can benefit from further developing a cash-flowing asset.
