In-App Purchases vs Subscriptions
IAP earns one-time revenue; subscriptions earn it again and again. That difference in predictability is why subscription apps can outspend on UA.
Key takeaways
- In-app purchases earn one-time revenue per buy; subscriptions earn recurring revenue.
- Subscriptions give predictable LTV and a higher allowable CAC; IAP suits some categories better.
- Many apps blend both in a hybrid monetization model.
How you monetize shapes how you can acquire. The choice between in-app purchases and subscriptions is not just a revenue decision, it determines how predictable your LTV is and therefore how hard you can push on UA.
How each model works
IAP earns revenue each time a user chooses to buy something, from consumables to one-off unlocks. Subscriptions charge on a recurring schedule for ongoing access. One is episodic and user-driven; the other is continuous and predictable.
Why subscriptions favor UA
Recurring revenue makes LTV predictable, which lets you set payback targets and confidently pay more to acquire a user. That predictability is exactly why subscription apps can outbid one-time-revenue apps for the same install.
When IAP fits
Plenty of categories monetize better with purchases: many games, transactional apps, and products people use in bursts rather than continuously. Forcing a subscription onto the wrong model can suppress both revenue and goodwill.
Hybrid models
The two are not mutually exclusive. Many apps combine a subscription with in-app purchases, or ads with both, to capture different willingness to pay across the user base. Hybrid monetization can widen who you profitably acquire.
