Publishing an App on the Play Store: Passive Income or Waste of Time?

Before I published my first app on the Play Store, I did some income projections. I estimated about 500 downloads in the first month. At an average of 50 daily active users, with AdMob running, I worked out something like Rs 800 to Rs 1,200 per month.

The actual first month: 23 downloads. Zero active users by week four.

I don't know what I expected to happen differently. In retrospect, there were about 400 nearly identical apps already in that category. But the projections had felt reasonable at the time.

What the submission process actually looks like

The technical side is genuinely straightforward, and the tutorials that cover it are accurate. Create a Google Play developer account, pay the one-time $25 fee (roughly Rs 2,100), wait 2 to 3 business days for approval. Build your APK or Android App Bundle, write the store listing — screenshots, description, short description, category, content rating — and submit for review.

Review time is typically 24 to 72 hours for simple apps. Apps that request sensitive permissions (camera, contacts, precise location) get more scrutiny and sometimes take longer or ask for additional documentation.

The process is clean and well-documented. Google's developer console is usable. None of that is the problem.

The problem is what happens after you hit publish.

Organic discovery: how it actually works

Play Store search is not a level playing field for new apps.

Google's algorithm ranks results based on signals that new apps don't have: install history, ratings volume, review recency, and retention data. A freshly uploaded app competing against established apps in the same category starts with all of these at zero.

In a popular category — calculator, unit converter, to-do list, weather — the top results have been there for years and have hundreds of thousands of installs. The algorithm has every reason to show users those apps and no reason to take a chance on your new upload.

What creates organic visibility is specificity. An app called "Carpenter Measurement Converter" targeting woodworkers who search for that exact thing has a genuinely different competitive landscape than an app called "Unit Converter." The niche search query might have fewer people searching for it, but the competition is thin enough that a new app can actually rank.

Actually, that slightly overstates how easy it is. Even within niche searches, existing apps often dominate. Research before building is essential — search your intended niche on the Play Store and see who's there, how old those apps are, and whether their reviews suggest users are happy with them.

AdMob: the math behind the earnings

AdMob earns money when real users see real ads. In India, banner ad eCPM (earnings per thousand impressions) runs roughly Rs 6 to Rs 18 depending on app category and time of year. Interstitial ads (full-screen between actions) earn Rs 15 to Rs 40.

A simple calculation: 1,000 daily active users, average of 2.5 ad impressions per session, Rs 12 eCPM average = about Rs 30 per day = Rs 900 per month.

That math looks reasonable until you think about what it takes to get to 1,000 daily active users. That number represents people who installed the app, kept it, and open it regularly. For a generic utility app with no external promotion, getting to that user base organically can take years — if it ever happens.

My first app sat at under 40 daily active users six months after publication. At that level, AdMob earnings were genuinely negligible. The Rs 25 developer fee remained the most significant transaction I completed in connection with that app.

Maintenance: the part nobody mentions

"Publish once, earn forever" is the promise. The reality includes ongoing maintenance.

Android releases major updates annually. APIs get deprecated. Libraries need updating. Play Store policy changes happen. If your app hasn't been updated in 12 to 18 months, users on newer Android versions will leave one-star reviews saying the app crashes. Eventually, Play Store may add warnings to your listing or remove it from search results.

A simple app might need 2 to 4 hours of maintenance quarterly. That's not enormous, but it is not zero. The passive income framing is more accurate as "requires occasional attention" than "requires nothing."

When it actually makes sense

Publishing Play Store apps makes sense if you have an audience. YouTube subscribers, blog readers, newsletter recipients — people who trust your recommendation and will install something you tell them about. An audience of 5,000 engaged followers who install your app gives you a starting user base that pure organic search can't provide.

It makes sense if you do genuine competitive research first and find a niche where the existing apps are old, poorly rated, or missing obvious features. Those gaps exist. Finding them takes time, but they're real.

It doesn't make sense as a first experiment in passive income if you're planning to publish one general-category app, wait for organic installs, and collect AdMob revenue. That plan works for very few apps and not for reasons that are controllable.

The multiple-app approach is more commonly successful than the single-app approach. Developers who publish 8 to 12 niche apps and get two or three of them to meaningful install counts can build a real income base. It requires sustained effort and isn't passive in the way the income is usually described.

The Rs 25 developer fee is genuinely a low barrier to entry. That part of the promise is true.

But low barrier to entry means everyone who ever thought of this idea has tried it. The competition isn't people you can easily beat. It's established apps with years of install history and thousands of reviews, built by teams that have been doing this longer than you.

One app probably won't do it. Treating it as a skill-building process rather than a quick income stream is the framing that holds up over time.
