You install a free app on your lunch break, and within a minute it has asked to use your location, send you notifications and track you across other apps. Nobody handed you a bill, yet somebody is clearly getting paid. This post explains how free apps make money, what each model asks of you, and a few habits that keep the trade on your terms. WhatsOnTech is not here to make you delete everything, only to show you the whole deal.
Someone is always paying
Building an app is expensive: developers, servers and updates, often for years. When the store says the price is zero, that cost has not vanished; it has moved somewhere you cannot see at the checkout.
That is not a scandal. Commercial radio has run on advertising for generations. The WhatsOnTech view is that “free” really means “paid for another way”, and the useful question is which way.
How free apps make money: the six main models
Most free apps rely on one or two of these:
- Advertising. The app shows you ads and is paid according to how many people see or tap them. Think news, weather and casual games.
- Freemium. The basic version is free, and you pay to unlock more: extra storage, advanced features, or no ads. A small share of paying users often covers the free majority.
- In-app purchases. Many games are free to play, but extra lives, cosmetic items or in-game currency cost real money, and a few big spenders often bring in much of it. If a child uses your phone, make the app store ask for a password before purchases.
- Subscriptions and upsells. A free tier or trial leads to a monthly or yearly plan. Many trials renew automatically, so set a reminder when you sign up.
- Commissions and affiliate fees. Shopping, travel and delivery apps can earn a cut when you book, order or buy through them. The sale pays for the app.
- Sharing data with partners. Many apps share some information with advertising and analytics partners, firms that measure app use and target ads. Some can also end up with data brokers, companies that buy and sell information about people. Not every app sells your data, but it is worth checking what each one shares.
Why your attention and data are worth so much
An ad shown to a random person is worth a little; one shown to someone likely to buy, because the advertiser knows their rough age, location and interests, is worth far more. That gap is why ad-funded apps care so much about keeping you scrolling and knowing who you are.
“Targeted advertising” means choosing which ad you see based on what is known or guessed about you. The guesses draw on the apps you use, what you tap, where your phone has been, and an advertising ID, a code that lets ad companies recognise the same phone across apps.
Much of it happens out of sight, through ad and analytics code built into the app. WhatsOnTech’s rule of thumb: the more an app wants to know about you, the more likely its business depends on knowing it.
“If you’re not paying, you’re the product” is only half true
You have probably heard the old line. As a summary of how free apps make money, it captures something real: when advertisers are the paying customers, the app is built to serve them.
But the missing half matters:
- Plenty of free apps earn from upgrades, not from tracking you. A freemium notes app may collect very little and simply hope you upgrade.
- Paying is not an automatic privacy shield. Some paid apps still collect data or show ads. The price tag alone tells you little.
- You are rarely “the product” literally. What usually gets sold is the chance to show you an ad, and sometimes information about you. That still matters, but it is narrower than the slogan suggests.
The WhatsOnTech version is more accurate: if you are not paying with money, you are paying with attention, data, or patience with upsells. It is the same bargain we described in our look at AI, smart homes and wearables: real convenience in exchange for something private.
How to keep the trade on your terms
None of this makes free apps bad; many are excellent. The goal is a trade you make on purpose:
- Read the privacy details before you install. On the Apple App Store, scroll to an app’s App Privacy section. On Google Play, look for Data safety. Both are the developer’s own declarations, so treat them as a guide, not a guarantee.
- Review permissions now and then. Your phone’s settings list each app’s access to location, camera, microphone and contacts. Allow location only while using the app, and switch off anything an app does not clearly need.
- Limit ad tracking. On an iPhone, go to Settings, then Privacy & Security, then Tracking, and turn off Allow Apps to Request to Track. On Android, look for Ads in your settings, often under Privacy or Google, and delete your advertising ID. You will still see ads, just less tailored ones.
- Delete what you no longer use. An app you never open can keep the permissions you gave it. Removing it takes those away, but it does not cancel a subscription or delete your account, so do those first.
When paying is the better deal
For the few apps you open every day, paying can be the calmer choice. A small subscription or one-off upgrade often removes ads and nagging upsells, and supports the people who make it. Keep that list short, because small monthly fees add up, as our guide to saving money on streaming subscriptions explains. The WhatsOnTech approach: pay for what you rely on, and let the rest stay free.
The takeaway
Once you know how free apps make money, a vague unease becomes a clear choice. Most of these models are reasonable ways to fund software, and each asks something different of you. Free apps are not evil and paid ones are not saints, so check the privacy details, trim permissions, limit tracking, and pay for the few apps that earn it. WhatsOnTech’s job is to lay that bargain out in plain English before you tap install.
