How an email list became a 15-year safety net for a solo app developer

Teleprompter Pro, an app initially created by Joe Allen out of necessity during a freelance gig in 2010, evolved into a successful business without the initial aid of market research. Allen developed the app as a simple solution to a videography problem he encountered and uploaded it to the App Store, where it gained unexpected traction. Embracing the unpredictability of the App Store, Allen focused on product reliability rather than constantly chasing algorithm changes, leading to consistent revenue. Transitioning to full-time indie development, he prioritized personal customer support, using feedback to drive feature improvements and foster user loyalty. Additionally, Allen emphasized the importance of building an email list to maintain direct communication with users, which proved invaluable when shifting business models and launching new products. Throughout his journey, Allen advocated for slow, steady growth and highlighted the benefits of engaging with users and attending industry events.
