How to Safely Buy a Mobile App Using Escrow: Verify Source Code, User Metrics, and Monetization

Why Buying a Mobile App Requires Caution

A mobile app’s value is tied to three intertwined assets: the source code that drives functionality, the active user base that generates engagement, and the monetization mechanisms that turn usage into revenue. If any of these pillars is misrepresented, the buyer can inherit hidden technical debt, face copyright infringement claims, or discover that the advertised audience consists largely of bots or incentivized installs.

Unlike a static website, an app often relies on platform‑specific SDKs, push‑notification services, and backend APIs that may be tied to the seller’s developer accounts. Transferring ownership therefore requires more than a file hand‑over; it demands coordination with Apple App Store Connect, Google Play Console, and any third‑party ad or analytics providers.

Escrow mitigates these risks by linking the release of funds to verifiable proof that the code repository is complete and licensable, that analytics dashboards show genuine user activity, and that all revenue‑generating contracts are current and transferable. This creates a neutral checkpoint where both parties can confirm that the asset matches the description before money changes hands.

Preparing for the Purchase: Documents and Access

Start by requesting a complete copy of the app’s source code, preferably hosted in a private Git repository with full commit history. Ask for a README that details build instructions, required development environments (Xcode, Android Studio, specific SDK versions), and any third‑party libraries or plugins used.

Next, secure access to performance data. For iOS apps, request a read‑only role in App Store Connect that lets you view analytics; for Android, request access to Google Play Console or a linked Firebase project. Export reports covering daily active users (DAU), monthly active users (MAU), retention curves (day‑1, day‑7, day‑30), crash‑free users, and average session length for at least the last three months.

Finally, gather all monetization paperwork: ad network contracts (AdMob, Unity Ads, IronSource), in‑app purchase configurations, subscription terms, affiliate agreements, and any sponsorship deals. Having these documents ready before the escrow deposit reduces back‑and‑forth and lets you focus on verification rather than chasing missing pieces.

Verifying Source Code and Intellectual Property

Open the repository and look for a LICENSE file at the root. Confirm that the license covers all custom code and that any open‑source components are used under compatible terms (MIT, Apache 2.0, GPL, etc.). If you find components under restrictive licenses (e.g., GPLv3) that would require you to open‑source your own modifications, flag this early.

Run a quick grep for trademarked names, logos, or copyrighted assets that are not owned by the seller (for example, using “Firebase” in the app name without permission). Verify that the app’s bundle identifier, package name, and associated domains can be transferred to your own developer accounts.

If the app depends on a backend service, ensure that API keys, service accounts, and database credentials can be re‑issued or rotated. Ask the seller to provide documentation on how to create new credentials and to confirm that existing keys will be revoked after transfer. Our platform treats software listings similarly to other digital goods, so you can reference the what we escrow page to see typical code‑based assets held in escrow.

Analyzing User Metrics and Engagement

Break down installs by source: organic, paid search, social ads, referral, or cross‑promotion. Calculate the effective cost per install (CPI) for any paid campaigns and compare it to industry benchmarks for the app’s category to gauge whether the acquisition strategy is sustainable.

Examine retention curves. A healthy app typically shows day‑1 retention around 40‑60 % for casual games and 20‑30 % for utility apps, with day‑30 retention above 5‑10 %. Sharp drops or unusually flat curves can signal botted installs or low‑quality traffic.

Look for anomalies such as sudden spikes in installs that are not matched by increases in session count or revenue. Request raw event logs (e.g., Firebase Analytics export) or use third‑party verification tools like Adjust or Appsflyer to validate that active users are real people performing meaningful actions within the app.

Additionally, review crash‑free users and average session length; high crash rates or very short sessions often indicate poor user experience, which can undermine future monetization efforts.

Reviewing Monetization and Revenue Streams

Ask for revenue reports broken down by source: banner ads, interstitial ads, rewarded video, native ads, in‑app purchases (consumables, non‑consumables), and subscriptions. Request the corresponding payout statements from Google Play or Apple App Store to ensure the reported numbers match the platform’s actual disbursements.

Check the timing of revenue recognition. Some ad networks report earnings with a ‑‑‑day lag; verify that the seller is not inflating recent figures by counting pending payments as realized revenue.

Confirm that each monetization contract is transferable. AdMob, for example, allows a simple API‑key update once the new owner is verified in the AdMob account, while certain mediation platforms may require re‑approval of the app. Subscription revenues often hinge on the seller’s merchant account; you may need to establish a new merchant identifier and migrate existing subscribers, which can involve communicating with Apple or Google about subscription transfers.

If the app includes a backend that serves ads or stores user data, ensure that any associated server costs, domain registrations, and SSL certificates can be transferred or re‑issued without service interruption.

Closing the Deal and Post‑Sale Steps

Once you have verified that the source code, analytics, and contracts match the agreed description, notify the escrow provider to release the funds. The seller then transfers ownership of the repository (by adding you as an admin or transferring the entire account), updates the developer console accounts to reflect your email or business entity, and hands over any associated domains, mailing lists, or social‑media profiles tied to the app.

After the transfer, update the app’s privacy policy and terms of service to reflect the new owner, and push a version bump if required by platform policies. Notify users of the change if the app’s data handling practices will change, as both Apple and Google may require disclosure.

Monitor key performance indicators for the first 4‑6 weeks: DAU/MAU ratio, crash‑free users, and revenue trends. If you negotiated a holdback, keep a agreed‑upon percentage of the purchase price in escrow for that period to cover any undisclosed issues that surface post‑transfer.

Consider setting up automated alerts for revenue drops or spikes in crash rates so you can react quickly. A smooth handover not only protects your investment but also preserves the app’s reputation with its existing user base.

Legal, Tax, and Transfer Considerations

Before closing, verify that the seller has the legal right to sell the app. This includes confirming that any employment or contractor agreements assign intellectual property rights to the seller, and that no third‑party claims (e.g., from a former co‑founder) exist.

Determine whether the sale constitutes an asset purchase or a stock purchase, as this affects liability exposure. In an asset purchase, you acquire the code, domains, and contracts but not the seller’s liabilities; in a stock purchase, you may inherit undisclosed debts. Most mobile‑app transactions are structured as asset purchases for simplicity.

Consult a tax professional about the treatment of the purchase price. In many jurisdictions, the acquisition of intangible assets like software and user bases may be amortized over a useful life, while any goodwill component may be subject to different rules. If the transaction crosses borders, be aware of withholding taxes on royalties or licensing fees that could apply to ongoing ad‑network payouts.

Finally, ensure that any data‑privacy obligations (GDPR, CCPA, etc.) are honored. Verify that the seller has proper user consent records and that you will assume responsibility for maintaining those records after transfer.

Using Escrows Click Dashboard – A Practical Walkthrough

After signing up, create a new transaction and select “Mobile App” as the asset type. The dashboard will prompt you to upload the purchase agreement, which should outline the escrow timeline, verification windows, and any holdback terms.

Invite the seller to the transaction via their email; they’ll receive a secure link to deposit the source‑code repository access (as a collaborator), add analytics‑dashboard viewers, and upload contracts. All file exchanges are logged with timestamps, making it easy to prove what was shared and when.

Use the built‑in checklist to tick off each verification step: code review completed, analytics validated, contracts confirmed. Once every item is marked, the “Release Funds” button becomes active. Clicking it triggers the escrow provider to send the payment to the seller’s linked bank or wallet, completing the sale.

Should a dispute arise, either party can open a ticket from the dashboard. The funds remain locked while the platform mediates, reviewing the submitted evidence against the original agreement. This process protects both buyer and seller without needing to involve external legal counsel unless the issue escalates.
