Measuring Apple Search Ads ROAS with Adapty, RevenueCat, and Superwall

How to tie subscription revenue back to keywords with Adapty, RevenueCat, or Superwall, and the attribution gaps to watch.

Updated June 2026 · 6 min read

The short answer

Apple Search Ads tells you about taps and installs, but not whether those users subscribed. Adapty, RevenueCat, and Superwall track the subscription side: trials, conversions, renewals, and the revenue each user brings. To measure true ROAS you connect the two, so spend on a keyword can be matched to the subscription revenue it produced. Each tool can attribute revenue back to Apple Search Ads, and the real work is keeping that link clean so you judge keywords on money, not installs.

What the ad platform can and cannot tell you

Apple Search Ads reports impressions, taps, installs, and what they cost. That is the spend side, and it is honest as far as it goes. What it does not know is what happened after the install: whether the user started a trial, paid, stayed, or refunded. Stop at the install and every keyword looks like a cost with no return, because the return has not been connected yet.

The revenue layer

Adapty, RevenueCat, and Superwall sit on the other side of the install. They manage the subscription and record what each user actually does:

  • Trials started and whether they converted to paid.
  • Renewals over time, which is where most subscription revenue actually lives.
  • Refunds and cancellations, which pull revenue back out.

That record is the missing half. It is the revenue that the ad platform cannot see, attached to the individual users your ads brought in.

Connecting spend to subscriptions

Measuring ROAS means joining the two sides: the keyword and cost from Apple Search Ads, and the revenue from your subscription tool, for the same users. When that link is in place, you stop asking what an install cost and start asking what a keyword returned. A term that looked expensive at the tap can turn out to be your best earner, and a cheap one can turn out to be dead weight. The join is what reveals it.

The gaps to watch

The connection is easy to set up loosely and hard to keep honest:

  • Delayed revenue. A subscription pays out over weeks and renewals, so a keyword judged on day one always looks like a loss. You have to measure over a window.
  • Refunds. Revenue that appeared can reverse. Real return is what survives refunds, not what briefly showed up.
  • Broken attribution. If the link between an install and its later payments is fragile, revenue lands with no keyword attached and your ROAS quietly understates the truth.

From measurement to decisions

Measuring ROAS is only worth it if the number then drives the account. The point of connecting revenue to keywords is to bid more on what pays, pull back on what does not, and do it before a losing keyword drains the budget. Clean measurement that nobody acts on is just a nicer report. The revenue has to steer the spend, continuously, which is the part worth automating once you trust the pipeline.
