What is Mobile Measurement Partner (MMP)?

Definition, examples, and more

Definition

A third-party tool - like Appsflyer, Branch, or Adjust - that attributes installs, measures campaign performance, and tracks in-app behavior across paid and organic channels. MMPs can be helpful for understanding CAC, LTV, and ROI in a privacy-compliant manner.

How to Calculate

MMP-Tracked Metrics: CPI = Campaign Spend / Attributed Installs. CPA = Campaign Spend / Attributed Actions (trials, subscriptions). ROAS = Attributed Revenue / Campaign Spend. These calculations are done per campaign, per ad set, and per creative for granular optimization.

Example

A wellness app uses AppsFlyer as their MMP, integrated with Botsi for subscription events. AppsFlyer tracks that their Apple Search Ads campaign drove 5,000 installs at $3.20 CPI. Botsi feeds back subscription data: 750 of those installs became paid subscribers. The MMP dashboard shows: $16,000 spend / 750 subscribers = $21.33 cost per subscriber, with projected 12-month ROAS of 2.8x.

Why Mobile Measurement Partner (MMP) Matters

An MMP is the single source of truth for your paid acquisition performance. Without one, you are relying on each ad network's self-reported data — which inevitably double-counts installs and inflates results. A dating app was spending $80K/month across 5 channels. Each channel's dashboard showed impressive results, but when they implemented an MMP, they discovered 30% of installs were being claimed by multiple networks. The MMP's deduplicated data helped them reallocate $24K/month from underperforming channels.

Frequently Asked Questions

Which MMP should I choose?

AppsFlyer is the market leader with the broadest integrations. Adjust is strong for privacy-focused measurement. Branch excels at deep linking alongside attribution. Singular combines MMP and ad analytics. For most subscription apps spending $10K+/month on paid UA, AppsFlyer or Adjust are solid choices. Consider Botsi's integrations when selecting — seamless subscription data flow is critical.

How much does an MMP cost?

Pricing is typically based on attributed install volume. Most MMPs offer free tiers for small apps (up to 10K installs/month). Paid plans start around $500-2,000/month for growing apps. At scale, enterprise plans can run $5K-20K+/month. The cost is usually 1-3% of your ad spend — a reasonable price for accurate measurement that prevents wasted budget.

How does an MMP work with Botsi?

Botsi sends subscription events (trial started, subscription purchased, renewed, churned) back to your MMP. The MMP then associates this revenue data with the original install source, giving you a complete picture: 'Users from Campaign X have a $45 LTV and 3.5x ROAS.' This integration is essential for optimizing acquisition spend toward high-value subscribers, not just installs.
