Buying an existing mobile app starts with understanding how the product works, who uses it, and what the new owner will need to maintain. A working app can offer an established audience and operational history, but those advantages should be checked rather than assumed.
Start with the product and its users
Install the app and follow its main user journeys. Review onboarding, subscriptions, purchase flows, support requests, store ratings, and recent releases. Compare the advertised audience with analytics that show active users and retention over time. A download count alone does not explain whether people continue to use the product.
Separate revenue from ongoing costs
Ask how income is generated and which expenses are needed to sustain it. Hosting, third-party services, customer support, advertising, and maintenance can all affect the operating picture. Look for consistent records rather than isolated screenshots, and investigate changes in revenue or acquisition channels.
Review the technical handover
A developer should be able to explain the codebase, build process, dependencies, backend infrastructure, and release workflow. Check which accounts and assets can be transferred, who owns the intellectual property, and whether important functionality relies on one person or an external service. Document the questions that remain unanswered before making a decision.
Plan the transition before agreeing the deal
Set out the responsibilities for source code delivery, store transfer, infrastructure access, documentation, and support. Keep a record of what must be verified at each step. For a broader framework, this app acquisition guide discusses evaluation, valuation, due diligence, and post-acquisition planning.
The aim is a clear understanding of the product and its risks. Professional technical, accounting, or legal review may be appropriate for a particular transaction; no checklist can guarantee future performance.
It is very full post.
