How to earn from your app: ads, donations, subscriptions

You built a game or a useful app and people are using it — naturally you ask: can this also make some money? It can, but not every model fits every app. Here are three realistic ways, with examples and when each makes sense.

1. Ads (AdSense) — for fun apps with lots of traffic

The easiest to start with: a small ad shows on the app and you earn per impression and click. It makes sense when you have plenty of visitors and content they linger on — games, quizzes, calculators, daily-use tools.

• Pro: the user pays nothing, easy entry.
• Con: small sums until traffic is big; too many ads ruin the experience.
• Rule: one discreet ad, at the bottom, after the main content.

2. Donations — for useful, “from the heart” tools

A “Buy me a coffee” button (PayPal) works surprisingly well for tools that make someone's life easier: a converter, a planner, an educational app for kids. People happily give a little when something genuinely helped, and you don't have to introduce billing or accounts.

• Pro: no friction, no obligation to the user.
• Con: unpredictable — some months good, some empty.

3. Subscription / premium — for apps that solve a real problem

If your app saves someone time or money (salon bookings, records for a small business, a tool for a profession), charging a subscription is the healthiest model. Basic version free, advanced features (more users, reports, no ads) behind a small monthly price.

• Pro: predictable, stable income.
• Con: you must keep delivering value for the user to stay.

Which to choose?

The biggest mistake is smothering the app with ads too early. First build something people actually use and return to — revenue comes later, and more easily, once you already have an audience.
