How to Make Money with an App: A Practical Path to First Revenue

How to make money with an app: pick a buyer who already pays, charge from week one, choose web or store payments, and other ways to earn by building apps.

To make money with an app, build something that solves a costly, recurring problem for a group of people who already spend money on it, charge them from the first version, and choose a payment route (web payments or in-app store billing) that fits where they use it. Downloads and likes don't pay; a small number of paying users with a real problem does. This guide is the practical side: how to pick a market that pays, how to get the first payments, and what else you can earn from apps besides selling your own.

For a full rundown of business models such as subscriptions, freemium, ads and marketplaces, read our companion guide, how to make money from an app. This page assumes you've seen the options and want to get to revenue.

Start with who will pay, not with the app

Most apps that fail to earn anything were built first and priced later. Turn the order around.

Look for existing spending

The best sign that people will pay for your app is that they already pay for something worse: a clunky tool, a part-time assistant, hours of their own time, or a spreadsheet consultant. A physiotherapy clinic that pays a receptionist to phone patients about appointments will pay for a reminder and booking tool.

Prefer businesses for your first app

Businesses pay for tools that save time or bring in customers, and they decide quickly. Consumers can pay too, but usually in smaller amounts and in larger numbers, which means more marketing. If you're starting out, a narrow business niche is the shorter road. Our micro-SaaS ideas and app ideas for small businesses are full of examples.

Check the maths before building

Write it down: "If 40 clinics pay 39 USD a month, that's 1,560 USD a month." Then ask whether you can realistically find 40 clinics. If the answer needs 40,000 users, you're in a different business: one that depends on marketing at scale.

Build the smallest version someone would pay for

You don't need every feature, only the one that removes the pain. For the clinic: patients book online, get an automatic reminder, and can cancel with a tap. Staff see the day's schedule. That's it.

An AI app builder makes this cheap to try. A first prompt could be:

Build a booking app for a physiotherapy clinic. Patients pick a therapist and a free 45-minute slot, enter their name, phone and email, and get a confirmation email. They get a reminder email the day before with a link to cancel. Staff log in to see each therapist's schedule for the day and mark no-shows. Clean, calm design that works on phones.

You can build it in the Mythex app builder, publish it to a public URL, and show it to a clinic owner the same week. When an owner says "I'd use that", your next question is "would you pay for it?"

Charge from the first week

It feels polite to give the first version away. It's usually a mistake, because free users tell you what they'd like while paying users tell you what they need.

• Offer a founding price. "39 USD a month, locked in for as long as you stay, because you're helping shape it."
• Ask for payment before custom work. If a customer wants a feature, ask them to commit to a paid plan first.
• Start with simple pricing. One plan, monthly, cancel any time. Tiers can come later; see how to price a SaaS product.
• Use a real checkout. Stripe handles cards, receipts and subscriptions. Our guide to adding subscriptions with Stripe shows the setup.

Web payments or store payments?

Where your users are decides how you take money.

Web app with web payments

If people use your app in a browser, you take payments through a processor like Stripe and pay only its fees. You set your own prices, run trials as you like and change them without anyone's approval. Most business tools work this way.

Phone app in the stores

If you publish on the App Store or Google Play and sell digital features or content inside the app, the store rules apply. Apple's guideline 3.1.1 requires in-app purchase for unlocking features or content in the app, and both stores take a commission on those sales. As of November 2026, Apple's Small Business Program rate is 15% for qualifying developers; check each store's current terms.

In return you get easier buying (one tap, no card entry) and the trust people place in the stores. Consumer apps often find this worthwhile.

Doing both

Plenty of apps sell subscriptions on their website and offer in-app purchase in the phone app. Mythex Pro, for example, turns a published web app into an Android app for Google Play and an iPhone app sent to TestFlight, so one project can serve both channels. See the Mythex mobile app builder page, and our publishing guides for Google Play and the App Store.

Get your first ten paying users

Ten paying users is the milestone that proves the app can make money. Ways to reach them without a marketing budget:

• Go where they already talk. Industry forums, local business groups, Facebook groups for clinic owners, subreddits for your niche. Help first; mention the app when it fits.
• Contact them directly. A short, personal message to 30 well-chosen businesses beats a broad ad campaign at this stage.
• Offer to set it up for them. Importing their existing data for them removes the biggest reason to say no.
• Ask every customer for one referral. Business owners know others in their trade.

Our guide on how to launch an app and get your first users goes deeper on each channel.

Keep the money you make

Revenue that leaks away doesn't count. Watch three things:

1. Churn. If customers cancel after two months, ask each one why. Fixing the top reason is usually worth more than finding new users.
2. Running costs. Hosting, database, email, payment fees and any paid APIs such as AI models. Set a budget per user. On Mythex, hosting, databases and storage come from monthly Cloud credits included in the plan.
3. Your time. Support requests grow with users. Write a help page for the five questions everyone asks.

Other ways to make money with apps

Selling your own app isn't the only route.

Build apps for clients

Small businesses need booking pages, client portals, order forms and internal dashboards, and many can't hire a developer. With an AI builder, one person can deliver these in days. Charge a setup fee plus a monthly fee for hosting and changes. Our guide to starting a web design agency covers pricing and finding clients.

Build once, sell to a niche

Make one strong app for one trade, for example a booking app for dog groomers, and sell it to groomer after groomer with their own logo and colours.

Sell the app itself

An app with steady revenue can be sold. Buyers look at monthly revenue, churn and how much work it needs to run. See how to sell a side project.

Turn your own process into a product

If you run a business and built an internal tool that saves you hours, other businesses like yours may pay for it.

Mistakes that keep apps from earning

• Building for months before talking to a buyer.
• Pricing so low that a single support request wipes out a customer's yearly value.
• Depending on ads with a few hundred users. Ad income needs very large, very active audiences.
• Adding features instead of fixing why people leave.
• Ignoring store rules, then getting rejected for selling digital content outside in-app purchase.

The short version

Find people who already pay to solve a problem, build the smallest thing that solves it, charge them early, and listen hard to the first ten. You can build and publish the first version on Mythex's Free plan with no credit card, and move to Pro at 25 USD a month when you need a custom domain, code export or phone apps.
