Buying an App - A Guide to Acquiring Mobile Apps

The mobile app market is booming – this concise guide shows you how to get a piece of the action.

A no-fluff guide to spotting good apps, closing the deal, and running one properly once it's yours.

If you're reading this, you're either buying your first app or adding to a portfolio you already own. Either way, the fundamentals are the same. This guide covers what you actually need to know before you buy a mobile app – from reading the market to closing the negotiation.

Whether you're a side hustler or a seasoned Indiemaker, the aim here is simple: give you enough to make a sound decision and run the thing profitably afterwards. Buying is often faster than building from scratch, and much of what follows assumes you'd rather acquire something with traction than start cold.

Understanding the mobile app market

Market overview

The app market is large and still growing. Global app revenue has been projected to reach roughly $613 billion by 2025, and the longer arc points higher still – we walk through where the numbers are heading in the mobile app economy, 2025 to 2027 outlook. The short version: there is plenty of demand, millions of apps, and billions in downloads. For a disciplined buyer, that's opportunity.

Types of apps

Match the app to your skills, your network, or your existing business.

• Utility apps: calculators, weather, converters
• Games: strong growth, but crowded and hit-driven
• Productivity tools: note-taking, habit trackers, schedulers
• Other niches: health, fitness, education, AR/VR

If you're a developer, dev tools or games play to your strengths. If you're a marketer, content, productivity, social or lifestyle apps are usually the easier lift.

Market trends

Popular categories

Keep an eye on where attention is moving. Buying late in a trend can still make sense if you're bolting the app onto something you already run, but go in with your eyes open.

• Current winners: gaming, business, and education
• Fast movers: AI tools, wellness, mindfulness, financial literacy
• Watch out: what's hot now can cool quickly

Pokémon GO made AR apps briefly unavoidable. Today it's AI and machine-learning apps pulling the attention.

Emerging technologies

As the underlying tech shifts, so does an app's earning potential. Apps built around these areas tend to have more room to grow.

• AI and machine learning
• AR/VR
• Blockchain

Market analysis tools

App store analytics

App store analytics let you see behind the listing – downloads, engagement, and revenue signals. Useful tools include:

• Data.ai
• SimilarWeb
• Sensor Tower

Say you find an app on Indiemaker with high engagement but modest downloads. Dig into the analytics and you might see strong retention and positive reviews. That tells you the product works and the real gap is marketing – a very different buy from one where users try it once and leave.

Identifying potential apps for purchase

Finding apps for sale

Two main routes: curated platforms and private sales.

Curated platforms

A curated platform like Indiemaker gives you a spread of listings in one place, with the transaction and asset transfer handled in a structured way rather than left to a stranger and a spreadsheet. That structure is the edge over cold self-sourcing – you spend your time evaluating apps instead of chasing sellers.

• Indiemaker

One buyer picked up a utility app with a loyal user base through Indiemaker, tidied up the interface, and doubled its active users within six months.

Private sales

Some deals never reach a listing. You can approach app owners directly, or watch niche communities where builders talk shop. It can work, but the burden of vetting, paperwork, and transfer sits entirely on you, so weigh the effort against buying somewhere the process is already handled. Whichever route you take, use a third-party escrow service such as Escrow.com to hold funds and document every step of the handover.

Evaluating app quality

User reviews

App store ratings tell you a lot if you read them properly. Look at three things: the overall star rating, the pattern of bug and crash complaints, and whether quality has held up over time.

Consistent crash complaints usually mean real work ahead, or a product that was never solid. A steady 4.5-star rating with reviews praising usability is a stronger bet – though it's still no substitute for looking under the bonnet yourself.

Technical analysis

Use analytics tools to check the fundamentals, and ask:

• Is it built on current, supported technology?
• How does it perform under real use?
• Does it lean on third-party services that could disappear or raise prices?
• Is there recent activity in the code repository?

An app with great features on outdated tech might need a costly rebuild – a real cost to factor in. If you're a developer and everything else stacks up, that same app can be a good buy at the right price. When the technical side gets serious, follow a proper process; our guide to technical due diligence without getting duped covers what to check before you commit.

Business model

How an app makes money is the whole game. Ads, subscriptions, in-app purchases – understand the model and whether it holds up as you scale.

• Ads
• Subscriptions
• In-app purchases

An app living purely on ad revenue is exposed if ad rates fall. A solid subscription model tends to deliver steadier, recurring income and usually the better long-term return.

Due diligence

Financial records

Ask for:

• Monthly revenue and expenses
• Profit margins
• Access to the payment processor (Stripe, PayPal)

If revenue is rising but so are costs, find out why before you get excited. Temporary spend is one thing; a structural cost problem is another.

Legal and compliance

Confirm the app is legally clean. Nobody wants to inherit a lawsuit.

• Intellectual property ownership
• User data compliance (GDPR, CCPA)
• Any history of app store policy violations

Steer clear of apps with unlicensed or scraped content, or undisclosed partnerships that could unravel later.

Negotiating the purchase

Setting the price

Anchor your offer to what comparable apps have actually sold for. Curated and listing platforms keep archives of past sales – use them.

Price on trailing profit, not on projections. For apps and small software tools, a common range is roughly 3–5× annual profit, measured on the last twelve months. Content-style apps that behave more like publications sit lower, nearer 2–3×. If the app is under about six months old with little trading history, don't price it on a multiple at all – value the assets themselves (the code, the users, the intellectual property) and expect a discount. Forecasts and "future potential" are where buyers overpay, so leave them out of the number.

Illustrative example: a comparable app nets about $6,000 a year in profit and changed hands at 4× – around $24,000. The one you're eyeing has stronger retention and cleaner books, so the top of the range is defensible. Weaker numbers, and you'd anchor lower.

Weigh:

• Trailing profit and margins
• Retention and real traction
• How clean and complete the books are

Negotiation strategies

• Counter the opening ask – almost always
• Be genuinely willing to walk
• Bring in an advisor or mediator on bigger deals

Seller wants $50k? Counter at $35k. You might land near $42,500 with a short post-sale support window included.

Contract terms

Asset sale agreement

An asset sale agreement sets out exactly what you're buying, fixes the terms, and keeps both sides out of a dispute later. It spells out the detail – from the transfer of intellectual property to who is responsible for what – so nothing is left to assumption. Skip it and you're buying ambiguity, which is how a promising acquisition turns into a legal headache before it earns a penny.

Detail:

• All intellectual property
• Codebase and data
• Transfer schedule
• Liabilities and warranties

Include clawbacks or conditions covering false claims by the seller.

Escrow and transfer

For deals above pocket-change size, run the money through a third-party escrow service such as Escrow.com so funds and assets change hands in the right order. Indiemaker supports the handover itself and can help facilitate the transfer, even when the deal originated elsewhere. Getting the mechanics right matters more than people expect – our guide on how to transfer digital assets like a pro walks through the steps that trip buyers up.

Post-purchase steps

Integration and testing

Once the app is yours, get it working inside your existing setup and confirm everything runs as expected. Put it in front of real users before you go live – they'll surface issues you'd miss and give you feedback worth having.

• Connect the app to your CRM, analytics, and push tools
• Run QA across every OS version
• Onboard your team, if you have one

Your new app should slot in with tools like Mixpanel, Firebase, or HelpScout.

Marketing and promotion

App store optimisation (ASO)

Help the app get found in a crowded store. Keywords, descriptions, and visuals all pull weight on visibility.

• Use App Radar or Keyword Tool
• Refresh your listing visuals and keywords
• Localise the listing if you have international traffic

Use keyword research to find the terms worth targeting, and make sure your screenshots and icon earn the tap.

Launch campaigns

Run targeted campaigns to drive downloads – paid social, creator partnerships, and email all have a place.

• Social media
• Influencer partnerships
• Email and affiliate promotion

Work with niche creators to demo the app in exchange for an affiliate revenue share.

Ongoing support and maintenance

Customer support

Set up a proper support system. Users who feel looked after stay, and a good response can turn a complaint into loyalty.

• Helpdesk via Freshdesk or Zendesk
• A dedicated support email
• Self-service documentation

Regular updates

Keep the app current with a steady release rhythm. Bug fixes, new features, and security patches are what keep it alive over the long run.

• Bug fixes
• Security patches
• User-requested features

A biweekly or monthly update cycle is a sensible default.

Conclusion

Buying a mobile app isn't just a transaction – it's a launchpad. Do it well and a straightforward acquisition becomes a profitable, ongoing business.

Stay sharp, do the homework, and don't skip the boring steps. You're not buying an app. You're buying a business.
