Do You Need an MMP? A Decision Guide for Early-Stage App Teams
An MMP is an arbitration layer for competing ad-network attribution claims. If you run one paid channel — or none — you probably need something else. A decision guide.
A Mobile Measurement Partner is an arbitration layer for competing ad-network attribution claims. That is the job. Everything else an MMP sells is built around it — which means the question is not "is my app big enough for an MMP" but "does anything in my acquisition mix actually need arbitrating."
You need an MMP when two or more ad networks are independently claiming credit for the same app installs and someone neutral has to settle it. That is what an MMP is for.
You do not need one for deep linking, deferred deep linking, sending one URL to the right app store, running a referral programme, or attributing installs to a blog post or creator link. Those are jobs MMPs happen to bundle, not jobs that require an MMP. Teams buy MMPs for those jobs because for years no one else sold them separately.
If you are running paid media across several networks at scale, an MMP is the right answer and this article will say so plainly. If you are not, you are likely about to pay per-install pricing for a referee at a match with one team.
What is an MMP?
A third party that decides which marketing source gets credit for an app install, and reconciles competing claims between ad networks. AppsFlyer, Adjust, Branch, Singular, Kochava and Airbridge are the main ones.
The reason they exist is not obvious until you understand one thing about how app-install ads work.
The problem MMPs solve
When you create an app-install campaign on Meta, you don't supply a tracking URL. You supply the app — a store ID or package name. Meta's own infrastructure generates and owns the click through to the App Store or Play Store. A link exists. You never see it, and it never touches your servers.
This makes Meta what the industry calls a self-reporting network (SRN), sometimes a self-attributing network. Google Ads, TikTok, Snap, X and Apple Search Ads work the same way. The consequence is that attribution runs backwards from what you would expect:
Rather than matching a click you observed to an install you observed, you report the install and ask the network whether it claims it.
AppsFlyer describes their own side of this plainly: on first app launch they check whether traffic is expected from any self-reporting network, then query the relevant networks using the new install's device ID — where a device ID is available and ATT consent has been granted on iOS — through APIs the networks themselves define.
Every network answers that question using only its own data. Adjust gives a clean illustration of what goes wrong: a user views a Facebook ad, then clicks a Snapchat ad, then installs. A neutral arbiter credits Snapchat. Meta credits Facebook. Both are answering honestly; neither can see the other.
Run three networks and their self-reported install counts will sum to more than your actual installs. That is not fraud. It is arithmetic.
The framing that makes the decision easy. An MMP is an arbitration layer, not a measurement layer. Everything else it sells — dashboards, cohorts, deep linking, fraud scoring — is built around that core function. Hold on to this and the buying question answers itself.
When do you need an MMP?
These are genuine hard requirements. If any apply, buy one.
| Situation | Why an MMP is required |
|---|---|
| You run two or more paid ad networks | Self-reported claims overlap and over-count. Nothing else deduplicates them |
| You need row-level Meta attribution data in your own warehouse | Meta's Advanced Mobile Measurement programme is delivered exclusively through approved MMPs. No direct-to-advertiser route exists |
| You need user-level attribution on iOS | The self-reporting network query API is available only to certified MMPs |
| You buy from long-tail or incentivised networks | Install fraud filtering is not something you will build |
| You need SKAdNetwork conversion-value management across networks | One schema has to serve every network. Coordinating that manually is a full-time job |
On the second row: Meta paused Advanced Mobile Measurement (AMM) in 2021 and re-enabled it on 17 June 2025, now covering both iOS and Android. By default Meta does not permit distribution of device-level data with unrestricted attribution information; accepting the AMM Terms removes that restriction.
Two things about AMM catch teams out. It is not retroactive — full attribution visibility applies only to devices attributed after the terms are signed, and in-app events inherit the restriction status of the conversion they attribute to. And its onward-sharing terms are restrictive: row-level Meta data received via an MMP is meant for your own servers, not third-party ones.
Do this today if you run Meta app campaigns. Sign the AMM terms now, regardless of whether you have chosen an MMP. It costs nothing, and the cohort you lose while deciding is not recoverable.
When do you not need an MMP?
You run one paid channel
Meta's own SDK plus its Conversions API will give you campaign-level installs and purchase ROAS in Ads Manager. You do not need a third party to arbitrate between one claimant.
The gap is that these are Meta's numbers, marking Meta's homework, on Meta's windows. That is an acceptable trade at one channel and an unacceptable one at three.
You are Android-only or Android-heavy and want user-level data
The Google Play Install Referrer API is public. The Play Store app exposes it on-device and returns the referrer URL of the installed package plus client- and server-side timestamps for both the referrer click and the start of installation.
You can read that on first launch, POST it to your backend, and join it to your user ID at signup — no MMP in the path. This is roughly a week of work.
One caveat we would rather state than gloss. Meta encrypts its campaign metadata inside that referrer string, and every source we could find describes handing the decryption key to an MMP rather than decrypting it yourself. We have not found documentation of advertiser-side decryption.
Until that is confirmed, budget for "this install came from Meta" rather than "this install came from ad variant B in campaign X."
Your traffic source is a link you minted yourself
This is the big one, and it is where most of the overspending happens.
A referral link, a creator link, a newsletter link, a QR code on a poster — these are URLs you created and control. There is no walled garden. You observe the click directly. The entire self-reporting-network inversion described above simply does not apply, because there is no network to ask.
None of these require arbitration, because there is nothing to arbitrate.
The four jobs people wrongly buy an MMP for
| Job | What you are actually trying to do | Needs an MMP? |
|---|---|---|
| Deep linking | A link opens the right in-app screen when the app is installed | No |
| Deferred deep linking | The same link survives the install — user lands on that screen after downloading | No |
| Dynamic store routing | One URL sends iOS users to the App Store, Android to Play, everyone else to a web fallback | No |
| Referral attribution | Credit the right referrer for an install, and do not pay out on a guess | No |
| Content and creator attribution | Attribute installs to a specific blog post, creator, community post or partnership | No |
Every one of these is a feature MMPs offer. None of them is a feature that requires an MMP. They are bundled because MMPs were, for a long time, the only vendors building link infrastructure that survived an app-store install.
This is what LinkTrace is for. Two plain HTTPS calls — POST /api/v1/referral-links to mint a link, POST /api/v1/attributions on first launch to resolve it. No SDK.

}Pricing is flat: a free Starter tier with 100 links and 1,000 attributed installs, then $9.99/month and $29.99/month, with no per-install charge. The full plan-by-plan breakdown is on the LinkTrace pricing page, and the integration is documented in the developer documentation.
How LinkTrace attributes, stated plainly
LinkTrace uses probabilistic matching within a 24-hour window on both platforms. It returns attributed: false rather than guessing when there is no confident match.
We are specific about this because the alternative is worse. A referral system that always returns a referrer will hand out rewards for installs it guessed at. If you are paying ₹200 or $5 per successful referral, a confident-sounding guess is a direct cost. An honest false lets you decide what to do about the ambiguous cases instead of silently paying for them.
The same 24-hour probabilistic window applies to deferred deep linking and content attribution. Anyone promising guaranteed post-install destination fidelity on iOS is describing something the platform does not support.
What does an MMP actually cost?
Pricing verified against the vendors' own pricing pages on 24 August 2026.
AppsFlyer publishes rates. The Growth plan includes a Welcome Package of 12,000 free conversions to be used within the first 12 months; after that, conversions are priced at $0.07 each. Raw Data API access, custom dashboards and the API analytics suite are premium add-ons available on a 30-day trial, after which continued access requires a separate subscription.
Run that arithmetic for a small app. At 5,000 non-organic installs a month, the 12,000-conversion welcome allowance is gone before the end of month three. From month four you are at roughly $350/month. At 10,000 installs a month, roughly $700. Note also that if you wanted row-level Meta data via AMM, you would need the raw data add-on on top.
Branch does not publish prices. Its pricing page lists three tiers — Basics, Essentials, Enterprise — with a detailed feature comparison and no dollar figures anywhere; Essentials and Enterprise both route to "Request a demo." We are stating it that way rather than quoting a number because third-party sources currently report Branch's entry price at $59, $199, $499 and $500-plus per month. A spread that wide is evidence that none of those figures should be repeated.
Branch's own feature matrix does tell you something useful about who each tier is for: the Basics tier caps ad partners, data partner webhooks and ad partner postbacks at three each. The entry tier is built for a team running a handful of ad networks — which is to say, for the arbitration job. We have written that up in full, source by source, in LinkTrace vs Branch and LinkTrace vs AppsFlyer.
The honest comparison. LinkTrace's $29.99/month and AppsFlyer's $0.07/conversion are not measuring the same thing, and we are not going to pretend otherwise. That $0.07 buys self-reporting-network arbitration, SKAdNetwork conversion-value management, fraud detection and cohort analytics. LinkTrace does none of those.
The argument is narrower and, we think, harder to dismiss: if you are paying per-conversion pricing while using none of the arbitration functions, you are buying a referee you do not need. Check your own usage before renewing. If your MMP dashboard is mostly showing you referral and organic-link data, that is the signal.
When LinkTrace is the wrong answer
Stated by name, because roundups that always conclude "we win" deserve to be discounted.
Buy an MMP instead of LinkTrace if:
- You run paid acquisition on two or more networks and need the numbers to reconcile
- You need row-level Meta attribution in your warehouse — AMM is MMP-only, full stop
- You need iOS user-level attribution from ad networks
- You need SKAdNetwork or AdAttributionKit conversion-value schema management
- You need install fraud detection
- You need ad-network postbacks, ROAS modelling or multi-touch attribution
We do not do any of that, we are not planning to, and pretending otherwise would waste your evaluation time.
Build it yourself instead of using LinkTrace if:
- You are Android-only, you have engineering capacity, and Play Install Referrer plus your own matcher covers your needs. This is genuinely the largest alternative to us and we would rather you knew that up front.
- You need only basic direct deep linking with no install-survival requirement. Universal Links and App Links are free and built into both platforms. If a user always has your app installed before they click, you do not need us either.
The case for LinkTrace is narrow on purpose: link infrastructure that survives an app-store install, for teams whose traffic comes from links they own rather than ad networks they rent.
A four-question decision checklist
- How many paid ad networks are you running? Two or more → MMP. One or zero → keep going.
- Do you need attribution rows inside your own database, or is a dashboard enough? Dashboard is enough → Meta's SDK plus Conversions API covers it.
- What share of your installs is iOS? Heavily Android → much of this is buildable in-house. Heavily iOS with paid media → MMP.
- Where does your traffic actually come from? Referrals, creators, newsletters, communities, your own website → you need link infrastructure, not arbitration.
If you answered "one network," "rows in my database," "mostly Android" and "links I own," you are the case this product was built for.

Method note
Vendor pricing in this article was read from AppsFlyer's and Branch's own pricing pages on 24 August 2026 and is stated as of that date; MMP pricing decays quickly, so verify before making a decision on it. Platform mechanics are sourced to Meta's, Apple's and Google's own developer documentation where available. Claims about Meta's internal behaviour that are sourced to MMP documentation rather than Meta's own are second-hand: Meta's MMP API specification is not public. Where we could not verify something — advertiser-side decryption of the Meta install referrer, in particular — we have said so in the text rather than filling the gap.
