CTV Advertising for Mobile Apps: Measure the Living Room Like Mobile

Every mobile marketer has a number they'd defend in a budget meeting: CPI, D7 ROAS, cost per payer. Ask the same team what their TV ads earned, and you'll usually get a reach figure, a frequency cap and a brand-lift study.

Those numbers say how many people might have seen the ad. None of them says whether anyone opened the app.

That gap is the biggest thing holding back CTV advertising for mobile apps, and it gets more expensive every quarter, because the audience already lives on both screens. In AppsFlyer's cross-platform data, the most common non-gaming journey bounces between phone and TV at nearly every step, with nearly 57% of volume moving from mobile to CTV at step two. And the money is following: the IAB expects US digital video ad spend to pass $80 billion in 2026, more than 60% of all TV and video spend for the first time.

In the video below, RZR CEO Aman Sareen, who built one of the first CTV platforms in the US, explains what changes when you bring mobile performance discipline to the living room.

TV is still graded on attendance

TV budgets have always lived at the top of the funnel, so TV measurement grew up around reach, frequency and brand lift. As Aman says in the video, there is "no direct correlation" between brand lift, reach or frequency and financial outcomes.

For a brand buying awareness, that's tolerable. For an app marketer judged on installs, payers and ROAS, it's a non-starter. So CTV stays in the "brand" column, even for teams that suspect it's working.

Three ways mobile yardsticks misread CTV

Teams that do test CTV often bolt it onto their mobile measurement and get the wrong answer. Three reasons:

1. There's no click. The ad plays in the living room. The install happens hours later on a phone, often after a search or a mobile ad that takes the last-touch credit. AppsFlyer frames this as the difference between attribution and contribution.
2. TV reaches households, not devices. One impression can lead to installs on two phones. MMPs match the TV impression to the install by household IP inside a view-through window, and the default settings were built for clicks.
3. CPI parity is a false benchmark. A view-through channel bought on CPMs isn't built to beat a click-based mobile CPI. Judge it on what it adds: incremental installs, payers and revenue.

What "measured like mobile" means at RZR

• Your MMP is the source of truth. CTV results land in AppsFlyer, Adjust or Singular next to every other channel, not in a separate TV dashboard.
• Decide windows and priority before launch. Agree on the view-through window, and on how CTV ranks against mobile touchpoints, before the first impression, not after the first readout.
• Bid on predicted value, not flat CPMs. We score each TV impression on what that household is likely to be worth on mobile, using what our mobile campaigns already know, so CTV doesn't start cold.
• Prove lift by geography. Household-level identity makes user-level holdouts unreliable on TV, so we measure incremental lift with geo holdouts.

Where RZR fits

Aman's description of the job is plain: help advertisers understand "what a television impression was able to bring financially to their ecosystem." RZR runs user acquisition, retargeting and connected TV advertising on one platform. TV viewing informs who we reach on mobile, and mobile behavior sharpens who we reach on TV. Our partnership with LG Ad Solutions adds first-party viewing data from US households to how we pick audiences and set bids, and our models draw on more than 10 years of mobile performance data.

One example: for a US sports app, shifting part of the mobile budget into CTV meant TV took 14% of spend but drove 56% of first-time deposits, and blended CPA across TV and mobile fell from $133 to $100. RZR Performance CTV was also a finalist for Most Innovative Use of CTV Technology in the 2026 AdExchanger Awards.

A number you'd defend

Aman's goal is to "attach exact business value to each impression a brand is buying across all types of media," not just performance media on mobile. The teams that get there first won't have the biggest TV budgets. They'll be the ones who can tell their CFO what each impression earned.

The living room doesn't need a click to perform. It needs a number you'd defend.
