Using four buy-once apps instead of four subscription equivalents at an average of $5/month each saves roughly $240–600 over five years, depending on the specific apps.
App Store buy-once apps receive updates at the developer's discretion. Most developers release regular updates because the App Store review process favours actively maintained apps.
Subscriptions make sense when an app requires significant server infrastructure — cloud sync across many devices, AI processing, or real-time collaboration. For solo use cases like voice notes, habit tracking or resume editing, the server cost is minimal, so a buy-once model is more consumer-friendly.
All apps below are by the same independent developer. Subscription cost estimates are approximate averages from publicly listed prices at time of writing — verify directly with each app before purchasing.
