The seller, a software engineer, is offering a portfolio of 25 music apps. These apps have rapidly grown to 50,000 monthly users within six months and are poised for further growth. Features include official song videos, lyrics, chat rooms, optimized AdMob ads, and news about artists, available in English and Spanish. The apps are based on consistent source code with each targeting different user segments. Monetized primarily through AdMob, the apps have generated $6,700 in profits over the past eight months, with an average monthly profit of $1,150 recently. The seller suggests potential for revenue increase through additional advertising networks, in-app purchases, or merchandise sales. The current reserve price for the portfolio is set above $10,000, with minimal monthly maintenance required. No social media accounts are linked, but the sale includes the source codes and multimedia content. The portfolio's main challenge is updating the apps, though only ten contribute significantly to the revenue. The seller highlights potential growth opportunities, estimating profits of up to $30,000 over 24 months with unchanged metrics. Additional income could stem from monetizing the young, music-loving user base through affiliate programs or in-app purchases. The seller, who has developed numerous apps through an Android engine, is selling to focus on building new portfolios. Post-sale support of one month is offered, with future use of the source code not intended. The seller is open to transferring 55 additional apps or unpublishing them after the sale.
