Why Does Every Simple Phone App Want a Subscription Now?
You need to merge two PDFs. You download something, it merges them, and then it puts a watermark across both pages and offers to remove it for £49.99 a year.
Or the flashlight. A flashlight is a switch. It turns on an LED that is already in your phone. And it wants a monthly plan.
This is not imagination and it is not a few bad actors. It is a structural shift in how phone software is paid for, and it happened for reasons that are more interesting than pure greed. Worth understanding, because once you can see the mechanism you can spot which kind of app you are installing in about ten seconds.
How we got here
The app stores launched into a price war that nobody could win. Paid-up-front apps competed against free ones, and free won, every time, on every chart. Within a few years the expected price of a piece of phone software had collapsed to zero, and "premium app" became a niche.
But an app is not a one-off cost to the person who made it. Both mobile platforms ship a major OS release every year, and each one can break things. Store policies change and require rework — new privacy declarations, new target API levels, new consent flows. Devices keep appearing with new screen shapes. Support requests arrive forever. Someone has to keep paying for all of that, and a purchase made once in 2019 does not.
Subscriptions solved that, and they solved it well enough that they became the default even where they do not fit. They produce predictable recurring revenue, they make a business easy to value, and both stores have actively encouraged them — including cutting their commission on subscriptions that pass a year, which is a direct financial nudge toward renting rather than selling.
So the drift was not a conspiracy. It was a rational answer to a real problem. The trouble is that the answer got applied to everything, including the flashlight.
The five ways a "free" app actually makes money
Every free app is monetised somehow. There is no exception, and the ones that appear to have no model usually have the least visible one. The honest taxonomy:
1. Advertising. You see ads; the developer gets a fraction of a penny per impression. Transparent and usually harmless, though it can involve tracking, and it pushes developers toward designs that maximise time in the app rather than getting you out quickly.
2. Subscription. Recurring payment for continued access. Fair for things with genuinely recurring costs — anything with servers, a content library, syncing. Much harder to justify for a self-contained tool that runs entirely on your phone.
3. One-time purchase. Pay once, own it. Increasingly rare, because it is harder to build a business on, but it is the model that best matches a tool whose costs do not meaningfully recur.
4. Freemium limits. Free tier with a cap — a number of uses, a watermark, an export restriction — and a payment to lift it. Honest when the cap is stated up front. Dishonest when the app advertises itself as free and only reveals the wall after you have done twenty minutes of work.
5. Data. Your usage, location, contacts or behaviour packaged and sold. This is the one that funds the apps which appear to have no business model at all. It is also the only one on this list where the price is invisible.
None of these is automatically evil. What matters is whether the app tells you which one it is before you have invested effort in it.
The ten-second check, before you install
You can identify the model from the store page without installing anything.
- Read the line under the install button. Google Play states "Contains ads", "In-app purchases", both, or neither. That single line rules out most guessing.
- Open the Data safety section. It lists what is collected and what is shared with third parties. An app with no ads, no purchases and a long collection list is telling you exactly what it sells.
- If it says in-app purchases, look at the price range. Play shows it. A range like "£2.49 per item" reads very differently from "£0.99 – £89.99 per item".
- Check the permissions against the job. A flashlight needs camera-flash access. If it also wants location and your contacts, the flashlight is not the product.
- Ask whether it needs a connection to do its job. A tool that works fully offline cannot be quietly sending your files anywhere. This is the single most useful property for anything handling documents or photos.
Those five checks take longer to read than to do, and they will save you most of the bad experiences described at the top of this article.
What a fair model looks like for a small tool
There is a reasonable middle ground that gets used less than it should: keep every feature available to everyone, charge nothing to look at your own files, and put the cost on the expensive part rather than behind a wall labelled Pro.
We build small Android tools, so it is only fair to say plainly how ours work rather than gesturing at other people's pricing.
Most of them — SafeMap, TrueLabel, Deep Calm, SOS Torch and the games — are free and ad-supported, with no account and no subscription. That is model one on the list above, stated plainly.
PDF Fox is the one with a paid tier, so it deserves the detail rather than a vague "free". Every tool in it is open to everyone — nothing is hidden behind a Pro wall. Reading, viewing and printing are always free. Saving a file you have created costs one credit, or two for a heavy conversion; you start with five and top up for free by watching a short ad. Credits live on your phone and spend offline, so you can stock up on wifi and then work with no signal. A single one-time purchase removes the ads and the credits permanently. There is no subscription, and there never will be.
That is a freemium credit system, which is model four, and we would rather describe it in a paragraph than call the app "free" and let you discover the credit prompt on your sixth save. An earlier version of that store listing said "no limits", which stopped being true the day the credit system shipped, and it got rewritten for exactly that reason.
The common thread across all of them is that they run on your phone. No account, no upload, no server holding your documents. That is not a marketing position so much as a consequence of being small: we cannot afford to run infrastructure for your files, which conveniently means we never have them.
The part worth remembering
Subscription creep is not going to reverse. It works, and the platforms encourage it. But the model an app uses is disclosed on its store page before you install, and reading that line is a habit worth ten seconds.
And when something is free, has no ads, and never asks for money — that is the moment to open the Data safety section and find out what the actual price is.
Prices and in-app purchase amounts vary by country and change over time — always check the current figure on the store page rather than trusting any article, including this one.
