App monetization is how a publisher earns revenue from a mobile app after it is built and installed. The download itself is usually free, so the money comes from what happens inside the app: ads shown to users, purchases they make, subscriptions they pay for, and offers they complete. The goal is to earn from the whole user base, not only the small share who spend directly.

How it works

Every monetization method converts some kind of user activity into revenue. Ad-based models pay you for attention, so revenue scales with impressions and engagement. Purchase-based models pay you when a user buys something, so revenue depends on how many users convert and how much they spend. Most publishers track a blended figure like ARPDAU to see what the average user is worth per day across all sources combined.

The main monetization models

• In-app advertising. You show ads such as banners, interstitials, and rewarded video, and earn based on impressions and engagement. This reaches every user, including those who never spend.

• In-app purchases. Users buy items, currency, or upgrades. A plan built on IAP alone often concentrates revenue in a small group of high spenders.

• Subscriptions. Users pay a recurring fee for access or premium features, which produces steadier, more predictable income.

• Offerwalls. Users complete offers in exchange for in-app rewards, and the publisher earns on each completion.

Why a hybrid mix wins

Relying on one model leaves money on the table. Pure advertising ignores users willing to pay for a cleaner experience, while pure IAP earns nothing from the majority who never open their wallet. A hybrid mix layers methods so each user is monetized in the way that fits them, which is why most top-grossing apps run ads, purchases, and reward-based formats side by side. The practical question is not which single model to pick, but how to combine them without one cannibalizing another. A rewarded format that hands a non-payer some currency, for instance, should be tuned so it does not undercut the purchase store that payers rely on.

Where offerwalls fit

An offerwall is one of the few formats that earns from users who will never make a purchase. It presents a menu of offers, sign-ups, surveys, and game trials, and pays the user in your in-app currency when they finish one. Because it targets the non-paying majority, an offerwall usually adds incremental revenue on top of existing ads and IAP rather than competing with them. RevU is an offerwall platform built for this role, giving publishers a way to monetize users who otherwise generate little direct income.

Common mistakes to avoid

• Monetizing only payers. Building a plan around purchases alone ignores the large non-paying base that ad and offer formats can still earn from.

• Overloading the experience with ads. Cramming in placements can lift short-term earnings while driving the churn that costs more over time.

• Skipping measurement. Without per-source and per-user metrics you cannot tell which methods actually add revenue and which just shift it around.
