Branch and AppsFlyer serve different primary purposes: Branch specialises in deep linking and user experience continuity, while AppsFlyer focuses on mobile attribution and ad performance measurement. For most apps, they are not direct competitors but complementary tools. The choice depends on whether your priority is routing users to the right in-app destination or accurately attributing installs and events to the right marketing channel. This article breaks down the key differences across deep linking, attribution, integration, and use cases so you can make an informed decision.
What makes deep linking different from standard app linking?
Deep linking sends a user directly to a specific screen or piece of content inside your app, rather than just opening the app’s home screen. Standard app linking simply opens the app. Deep linking carries context, so if a user taps an ad for a specific product, a well-configured deep link opens that exact product page inside the app, not the homepage. This directly reduces app onboarding drop-off and prevents users from losing their place after reopening an app.
There are three types of deep links worth knowing:
- Standard deep links: Work only if the app is already installed. If it is not, the user hits a dead end.
- Deferred deep links: Carry context through the install process. A user clicks a link, installs the app, and lands on the intended screen after first launch. This is what prevents lost users after install.
- Universal links and App Links: Native iOS and Android mechanisms that open the app directly if installed, or fall back to the web if not.
Without proper deep linking, common problems appear: a retargeting ad opens the wrong page, users disappear after install because they land on a generic screen and disengage, or a cart is lost after reopening the app. These are not minor UX issues. They directly affect conversion rates and retention.
How does Branch handle deep linking compared to AppsFlyer?
Branch is purpose-built for deep linking and user journey continuity. AppsFlyer offers deep linking as a supporting feature within its broader attribution platform. Branch’s core strength is ensuring that every link, whether shared on social media, in an email, via SMS, or from a paid ad, routes the user to exactly the right in-app destination, even across installs. AppsFlyer’s deep linking works well within its own attribution ecosystem but is secondary to its measurement capabilities.
Branch handles cross-platform link management with a centralised dashboard where you can create, test, and monitor links across every channel. It also manages edge cases well, such as users on unusual devices or those who have uninstalled and reinstalled the app. For teams where the wrong screen after an ad click is a recurring complaint, Branch’s dedicated focus on this problem makes it the stronger tool.
AppsFlyer’s OneLink product provides deep linking functionality tied directly to its attribution data. This is convenient if you are already using AppsFlyer for measurement, but it is not as flexible or feature-rich as Branch’s standalone deep linking infrastructure.
Which platform offers better mobile attribution accuracy?
AppsFlyer offers stronger mobile attribution capabilities than Branch. Attribution is AppsFlyer’s core product, and it is one of the most widely adopted mobile measurement partners (MMPs) globally. It integrates directly with hundreds of ad networks, including Apple Search Ads, Google, Meta, and TikTok, and provides granular data on which campaigns, creatives, and channels drive installs and in-app events. Branch provides attribution, but it is secondary to its deep linking functionality.
AppsFlyer’s attribution covers:
- Install attribution across paid, organic, and owned channels
- In-app event tracking tied to specific campaigns
- Retargeting attribution, including re-engagement and re-attribution
- Fraud protection through its Protect360 product
- SKAdNetwork support and probabilistic modelling for iOS privacy constraints
Branch does offer attribution reporting, but marketers who need campaign-level accuracy across multiple paid channels typically rely on AppsFlyer or a comparable MMP as their primary source of truth. Branch’s attribution data is most useful as a supplement, particularly for owned and organic channels.
What are the integration and setup differences between Branch and AppsFlyer?
Both platforms require SDK integration into your iOS and Android app, but they differ in complexity and setup time. AppsFlyer’s SDK is focused on event tracking and attribution, which means the initial setup involves mapping your key in-app events to the correct campaign goals. Branch’s SDK setup centres on configuring link routing, handling deferred deep link logic, and setting up fallback behaviour for edge cases.
AppsFlyer integrates directly with most major ad networks as a certified MMP, which simplifies postback configuration. Branch requires more deliberate link architecture planning, particularly if you are managing links across multiple channels simultaneously. For teams without a dedicated mobile developer, Branch’s link configuration can take more upfront time to get right.
That said, both platforms have solid documentation and support. The more important factor is usually internal: do you have someone who understands mobile attribution logic for AppsFlyer, and someone who understands URL scheme and routing logic for Branch?
Can Branch and AppsFlyer be used together in the same app?
Yes, Branch and AppsFlyer can run simultaneously in the same app, and this is a common setup for growth-focused teams. In this configuration, AppsFlyer handles attribution and campaign performance measurement, while Branch manages deep link routing and user journey continuity. The two SDKs do not conflict when implemented correctly, and each handles a distinct part of the mobile growth stack.
A typical combined setup works like this: a user clicks a Branch link from a retargeting campaign, Branch routes them to the correct in-app screen after install or reopen, and AppsFlyer records the attribution data for that install or event. Both tools receive the signal they need without duplication or conflict.
Running both does add SDK weight and maintenance overhead, so it is worth evaluating whether your current scale justifies the complexity. For apps with significant paid acquisition budgets and active retargeting campaigns, the combination is well worth it.
Which tool should you choose for your app’s growth stack?
Choose AppsFlyer if your primary need is accurate campaign attribution and paid channel performance measurement. Choose Branch if your primary need is deep link routing, reducing users’ don’t-open-the-app-again rates, or fixing broken user journeys after ad clicks. For most scaling apps, the right answer is both, used together for their respective strengths.
A practical way to decide:
- If users disappear after install or land on the wrong screen after clicking an ad, Branch’s deferred deep linking solves this directly.
- If you cannot tell which campaigns drive valuable users, AppsFlyer’s attribution gives you that visibility.
- If you are running retargeting campaigns and a retargeting ad opens the wrong page, you need Branch’s link routing alongside AppsFlyer’s re-attribution tracking.
- If budget is limited, start with AppsFlyer as your MMP and add Branch when deep linking issues become a measurable problem.
Getting this configuration right takes experience with both platforms and a clear understanding of your app’s user journey.

Frequently Asked Questions
How do I know if my app's deep linking is broken or misconfigured?
The clearest signs are users landing on your app’s home screen instead of the intended content after clicking an ad or shared link, a high drop-off rate immediately after install, or complaints about lost cart or session state after reopening the app. You can test this directly by clicking your own campaign links on a device with and without the app installed and verifying the destination screen. Tools like Branch’s link tester or AppsFlyer’s OneLink test mode can help you validate routing behaviour before campaigns go live.
What is the difference between deferred deep linking and retargeting, and do I need both?
Deferred deep linking handles the new user journey — it carries context through the install process so a first-time user lands on the right screen after downloading your app. Retargeting, on the other hand, re-engages existing users who have already installed the app but have become inactive. You need both if you are running acquisition and re-engagement campaigns simultaneously: deferred deep linking (via Branch) ensures new users are not lost after install, while retargeting attribution (via AppsFlyer) tells you which re-engagement campaigns are actually bringing users back and driving valuable in-app events.
Does adding both the Branch and AppsFlyer SDKs significantly affect my app's performance or load time?
Each SDK does add some weight to your app binary and a small amount of initialisation time at launch, but in practice the performance impact is minimal for most apps when both SDKs are implemented correctly. The more important consideration is maintenance overhead — two SDKs mean two sets of updates, two integration points to monitor, and two dashboards to manage. To minimise performance impact, ensure you initialise both SDKs asynchronously and only track the events that are genuinely useful to each platform rather than duplicating every event across both.
Can I use Branch or AppsFlyer for web-to-app flows, such as from a mobile website or email campaign?
Yes, both platforms support web-to-app flows, and this is one of the most valuable use cases for deep linking. Branch’s links can be embedded in emails, SMS messages, QR codes, and mobile web pages, routing users directly to the correct in-app screen whether the app is installed or not. AppsFlyer’s OneLink also supports this for attribution purposes. For email campaigns specifically, Branch is particularly strong at handling the redirect logic across different email clients and devices, which is notoriously inconsistent without a dedicated deep linking solution.
What happens to my attribution data when Apple's SKAdNetwork or Android's Privacy Sandbox limits tracking?
Privacy frameworks like Apple’s SKAdNetwork and Google’s Privacy Sandbox restrict user-level tracking, which means you receive aggregated, delayed, and sometimes incomplete attribution signals rather than deterministic install-level data. AppsFlyer has invested heavily in this area through its SKAdNetwork support, probabilistic modelling, and incrementality measurement tools, which help you make sense of campaign performance even with limited signals. Branch is less focused on this layer, so if iOS privacy attribution accuracy is a priority for your paid acquisition strategy, AppsFlyer is the more capable tool for navigating these constraints.
Is there a recommended order for implementing these tools if I am starting from scratch?
If you are starting fresh with a limited budget or team, implement AppsFlyer first. Getting accurate attribution in place early means you can make informed decisions about which channels and campaigns are worth scaling from day one. Once you have a paid acquisition strategy running and you start noticing deep linking issues — such as users landing on the wrong screen or dropping off after install — add Branch to address those routing problems. Trying to implement both simultaneously without a dedicated mobile developer can slow down your launch and introduce integration errors that are harder to debug later.
How do Branch and AppsFlyer handle users who uninstall and reinstall the app?
Both platforms have mechanisms to handle reinstall scenarios, but they approach it differently. AppsFlyer can identify reinstalls and distinguish them from new installs in your attribution data, which is important for avoiding inflated acquisition numbers and correctly attributing re-engagement campaigns. Branch focuses on the user experience side: it can carry deep link context through a reinstall so the user lands on the correct screen even after reinstalling the app. For a complete picture, you need both — AppsFlyer to correctly classify and attribute the reinstall event, and Branch to ensure the user journey continues seamlessly from where it left off.
