I've shipped 6 iOS apps to the App Store: ChatterCards (IELTS speaking prep), LingoDuel (competitive language learning), Serenight (sleep tracker), TrueHue (color perception test), Subscriptionly (subscription tracker), and WDTG — Where Did The Time Go (visual time tracker). All live. All with real users. None of them took more than a weekend to get from zero to "submitted for review." This guide is the distilled playbook from those 6 launches.
