Compare Three MMPs for Four-Channel Revenue Attribution

Compares AppsFlyer, Singular, and Airbridge for four-channel subscription apps, recommending Airbridge when its listed channels and revenue paths fit.

Best fit for a four-channel subscription app

• For Google, Meta, Apple Ads, and TikTok, Airbridge Core lists all four for cost aggregation and includes subscription and mediation-based ad-revenue aggregation.
• AppsFlyer ROI360 fits teams that want campaign-level cost and revenue reporting across subscriptions, in-app purchases, and in-app ads, with net ROAS for subscriptions and purchases.
• Singular fits teams that want subscription events sent through an SDK, server API, or subscription-platform integration, and ad-revenue measurement through user-level or impression-level inputs.
• Before choosing any MMP, match each channel, revenue source, cost feed, and integration to the exact plan and reporting method your app will use.

If your team spends across four channels, the right MMP is the one that can connect each channel’s spend and attributed installs to the revenue your app actually earns. Airbridge Core is a strong shortlist choice when your channels are Google, Meta, Apple Ads, and TikTok: its pricing matrix names those four for cost aggregation and lists subscription revenue aggregation and mediation-based ad-revenue aggregation.

A subscription-led app needs paid subscription events, renewals, and costs tied to campaigns. An ad-supported app needs revenue from ads shown inside the app. A mixed model needs both paths, with definitions finance can reconcile.

Define the four channels and revenue paths first

Start with the names of the four acquisition partners, then write down what each one must contribute. A channel may need attributed installs, campaign or ad-group cost, and conversion value reporting. Cost aggregation means bringing the spend from the channel into a shared reporting view; it is a separate job from assigning credit for an install or purchase.

Airbridge’s plan comparison describes cost and ad-spend aggregation as consolidating connected-channel spend for ROAS analysis. Its Core row names Google, Meta, Apple Ads, and TikTok, while the plan notes that Growth supports all channels. This distinction makes the list of four channels a concrete qualification test: match the names in your ad accounts to the channels shown for the plan you are evaluating.

Subscription revenue comes from a billing or subscription platform, including trial starts, paid conversions, or renewals that your setup sends into measurement. In-app purchase revenue comes from individual purchases. Mediated ad revenue comes from ads shown in the app and is typically passed from a mediation or ad-revenue source; it is not the same feed as subscription billing.

A team can have more than one revenue path. For example, a fitness app could earn recurring subscription revenue and also show a small number of rewarded ads to free users. A game or utility app could earn primarily from ads, with one optional paid upgrade. If finance expects one campaign ROAS number for the whole product, each required revenue path needs to enter the reporting system with clear source and event definitions.

Before looking at vendor claims, write a one-line requirement such as: “Google, Meta, Apple Ads, and TikTok costs; subscription revenue from RevenueCat; and impression-level revenue from our mediation setup.” This names the inputs rather than a vague goal like “revenue attribution.” Use the same one-line requirement in vendor evaluations, implementation tickets, and the first report review.

AppsFlyer: ROI360 combines cost and revenue workflows

AppsFlyer positions ROI360 as a combined cost-aggregation and revenue-measurement suite. In its ROI360 launch announcement, AppsFlyer says cost aggregation draws from up to 90 sources and that campaign reporting can place attribution-linked cost and revenue side by side across in-app ads, purchases, subscriptions, or a hybrid model. This makes ROI360 relevant for a subscription app that also earns through purchases or advertising.

For subscription and in-app purchase reporting, the same announcement describes receipt validation and a net ROAS view. AppsFlyer defines that net view as subscription and in-app purchase revenue with tax and commissions subtracted. That treatment can help a growth lead compare acquisition cost against revenue closer to the amount retained by the business, especially when gross store proceeds overstate the value available after fees.

AppsFlyer also describes an ad-revenue workflow. Its announcement says ad-revenue data can be available from day zero and identifies server-to-server integrations as part of data refinement. Its current ROI measurement overview also describes automated seven-day cost backfills and longer on-demand backfills. Those details matter when a team wants historical cost data filled during onboarding or needs to restore a cost series after a data interruption.

AppsFlyer’s ROI360 cost aggregation overview links to a Google Ads cost and ad-revenue guide.

The ROI360 cost overview describes three ways to record cost: through an API, a CSV Cost Import, or a cost value attached to an attribution link. It also lists cost and LTV measures such as ROAS, clicks, impressions, campaign ROI, and effective cost per install. That gives a team a practical fallback for a channel without an automatic feed and a defined set of fields to compare against its finance or BI export.

AppsFlyer’s ROI360 cost and revenue guide lists more than 80 API integrations for global and local ad networks and an option to include agency-fee calculations in cost. It also lists Cost ETL in the Advanced package, which sends campaign cost data to an AWS S3 or GCS bucket four times daily for a BI system. That Advanced condition matters when a team needs a warehouse feed for finance reporting.

Shortlist AppsFlyer when the central need is one view of costs and mixed revenue, particularly if its net subscription and purchase ROAS definition matches the number finance wants to review.

Singular: flexible event paths for subscriptions and ad revenue

Singular documents more than one way to send subscription events. Its Subscription Event Technical Implementation Guide describes three routes: custom revenue methods in the Singular SDK, events sent from a backend to the Singular REST API, or an integration with a subscription platform such as RevenueCat, Adapty, or Superwall. That flexibility can suit a small engineering team that already has a billing platform or prefers to send verified events from its own backend.

Its Android example separates a new subscription event from a renewal event, passes an amount and currency, and includes subscription and order identifiers and a purchase time. A team can use the same concepts when documenting its own event contract: name the event type, preserve the transaction identifier, and send the value and currency used by the billing system. Those fields help a growth report distinguish a new paid subscriber from later recurring revenue.

Singular recommends verifying purchases on a secure backend, filtering restored purchases to avoid duplicate revenue reporting, and sending subscription events without store receipts. For an Android implementation, it also recommends checking for renewals when the app resumes. These steps help keep subscription revenue events tied to verified purchases and reduce duplicate or missed renewal events.

Its ad-revenue onboarding guide walks through ad monetization connectors and an event associated with an ad being served, such as an ad-impression event, as input to its ad-revenue setup. The guide says the resulting report combines ad revenue with user-acquisition cost and attribution data, and that data updates hourly for the SDK Events setup.

For the SDK Events setup, reports show Android and iOS users who opted in to share IDFA; revenue for iOS users who did not opt in is treated as organic. For the user-level API route, Singular’s onboarding guide says reports combine ad revenue with acquisition cost and attribution, support ad ROI breakdowns, and can send user-level data to destinations. Data is available for up to two days prior; teams using multiple mediators can break reports down by mediation source.

Singular’s Android ad-revenue tracking overview explains that mediation data may arrive at either user level or impression level. Its ad-spend overview describes cost collection through more than 1,000 partner integrations and analysis across channels. Together, these pages make Singular worth evaluating when a team values multiple integration paths and wants to define whether its ad-revenue data enters at the user or impression level.

Singular also documents an estimation route for ad revenue. It uses average revenue per event in an existing SDK integration and recommends an event tied to an ad being served, such as ad_impression; teams without a custom impression event can use session. The onboarding guide describes enabling the feature and adding Ad Monetization data connectors. This route provides aggregate reporting with up to two days of prior data, making it a fit when event-based estimates meet the team’s needs and user-level output or SKAdNetwork revenue models are not required.

Shortlist Singular when its subscription-event path fits your stack and the ad-revenue method matches your app’s mediation data and iOS reporting needs.

Compare the documented revenue and cost paths

Airbridge’s mediation guide and third-party integration guide give the implementation context behind its two revenue rows: impression-level ad revenue enters through mediation, while subscription revenue connects through an external subscription platform. Airbridge Core permits up to two third-party integrations, with RevenueCat, Adapty, and Superwall given as examples. For a team using a subscription platform plus one mediation connection, that allowance gives a straightforward integration count; count every third-party system your intended setup needs before selecting the plan.

Airbridge documents a manual route for a cost source without a systematic ad-network integration. The ad-spend upload documentation describes uploading spend through an API when an ad network does not provide systematic cost integration. That path can preserve a cost record for a channel with a nonstandard feed, while an automatically connected source remains easier to maintain as daily spend changes.

Airbridge Core price and commitment

Airbridge’s pricing page lists a 30-day free trial, then $40+/mo, 500K data points included, and no annual contract. For a small team budgeting paid acquisition month to month, those terms make Core’s entry cost clear; the separate two-integration allowance determines whether the required subscription and mediation connections fit.

Let the revenue model change the shortlist

A subscription-led model puts subscription events first. Airbridge Core is a natural candidate when the four named channels are its listed set and its two-integration limit covers the subscription and other external systems you plan to connect. Singular also deserves a shortlist when the team prefers its SDK, backend API, or subscription-platform route. AppsFlyer is relevant when the subscription net ROAS view with tax and commissions removed matches the finance definition.

An ad-supported model changes the critical input from billing events to ad revenue. Airbridge’s pricing materials describe impression-level revenue through mediation. Singular documents both user-level and impression-level sources, and its onboarding guide gives different implementation and reporting details by route. AppsFlyer positions ROI360 to include in-app ads alongside purchases and subscriptions, with ad revenue available from day zero according to its announcement.

A mixed-revenue model requires two distinct data paths. One path must capture subscription or purchase revenue; the other must capture ad revenue.

A RevenueCat connection and a mediation connection consume two external integrations if both are configured as third-party connections. That makes Airbridge Core’s two-integration allowance a concrete fit check for a small stack; if you need a third system for a distinct required data path, include that in the plan comparison before implementation.

For teams buying traffic from four channels, avoid choosing on the basis of revenue-path breadth alone. A sound shortlist joins cost from each acquisition channel with every subscription or mediated-ad revenue stream the app earns. The shortlist should clear both tests before the team compares user interface, export, or support workflows.

Align the numbers before comparing ROAS

Finance and growth can read different ROAS values even when they use the same campaign data, because they may be dividing different revenue definitions by different cost periods. AppsFlyer’s ROI360 materials make one such definition visible: its stated net ROAS subtracts tax and commissions from subscription and in-app purchase revenue. Write that treatment beside any vendor report that uses gross proceeds so the two numbers are not presented as competing versions of the same metric.

Attribution windows also change which events are credited to an ad. Google Ads guidance says conversion windows can range from 1 to 90 days, depending on the source, and that Search and Display use a 30-day default when the advertiser has not customized the window. Google also notes that changing conversion and attribution windows can help maintain consistency and reduce discrepancies. This is a useful reminder to record each window: a 7-day report and a 30-day report include different sets of later subscription events.

Google Ads API documentation describes report segments that compare original, unadjusted conversion values with adjusted values. For an MMP evaluation, decide whether the team needs original purchase value, adjusted or refunded value, or net proceeds, then check that every candidate and the finance export apply the chosen definition consistently.

Attribution and incrementality answer different questions. Attribution assigns a conversion to one or more ad exposures under a selected model and window. The Media Rating Council’s outcomes and data-quality guidance describes randomized control experiments that compare results with control groups to assess incrementality. An MMP revenue report helps the team understand credited performance; a holdout or controlled experiment helps answer whether the advertising caused additional outcomes.

Assume a campaign spent $100 and generated $200 in gross subscription receipts, with $60 in tax and store commissions subtracted under the reporting definition. Gross ROAS is 200%, while net ROAS is 140% using $140 in net revenue divided by $100 in spend. Both calculations are correct for their stated inputs, but a weekly growth meeting needs one agreed definition before it decides whether to increase budget.

Use this short comparison checklist before interpreting vendor reports:

• Revenue source: Identify subscription platform, purchase receipt, or mediation source for each value.
• Revenue grain: Record whether ad revenue is user-level or impression-level, and whether subscription events distinguish trial, conversion, and renewal.
• Net or gross: State whether tax, store commissions, refunds, and cancellations change the reported value.
• Currency: Choose the report currency and record any conversion method used for source currencies.
• Attribution window: Record the click or view window and the date range in which late conversions can arrive.
• Cost source: Match each channel to an automatic cost integration or documented upload route.
• Reporting period: Keep the timezone, spend period, and revenue-event period consistent when you compare the same campaign.

Which MMP should a four-channel team shortlist?

The final rule is straightforward: choose the candidate whose documented cost connections cover all four actual channels and whose revenue inputs match every way the app earns money. Compare reports only after the team agrees on revenue basis, attribution window, currency, and reporting period. That gives a small growth team a defensible shortlist before it commits engineering time or reallocates paid spend.
