Audio to Text for WhatsApp is an iOS application designed to transcribe voice messages from WhatsApp and Telegram into text. This feature is particularly beneficial for users in situations where listening to audio messages isn't feasible, such as during meetings or in noisy environments. The transcription process occurs entirely on the device, eliminating reliance on servers or third-party APIs, which helps maintain a cost-effective structure. The app supports several languages and has garnered a dedicated international user base since its inception in 2017. In December 2024, new owners transitioned the app from a paid download model to a subscription-based model using specialized paywalls, which improved revenue predictability and scalability. Since the shift, monthly proceeds from the App Store have averaged around $2,500. The app benefits from high ratings and steady organic discovery, while operating costs remain low, primarily involving the subscription fee for the paywall service used. Marketing investments include approximately $116 monthly on targeted ads, yielding a 2–3x return on investment. Significant development costs occurred in February 2026 to introduce a credit system for user trials, reflected in the financials as a non-recurring expense spread over a year. The app appeals to a diverse audience, including professionals, people with hearing impairments, multilingual households, and travelers, supporting consistent organic growth. The sale of the app includes transfer of all assets such as source code, paywall configurations, a website, and accounts. The seller offers comprehensive transition support to ensure continuity, presenting this as a low-maintenance, profitable investment opportunity with a well-established history.
