The True ROI Playbook: what your apps actually earn.

01Why platform-reported ROAS lies to you

Every ad platform grades its own homework. Google Ads reports the conversions Google can attribute. Meta reports what Meta can see. Apple Search Ads reports Apple's view of Apple's traffic. Not one of them knows what the others spent — and not one of them knows what your apps earned outside their walls.

For ad-monetized publishers, the blind spot is enormous: your UA platform counts purchase conversions, but it has no idea what those users earn you in ad impressions — which for many portfolios is the majority of revenue. A campaign can look like a 0.4x failure in Google Ads while quietly printing money in AdMob.

Three structural gaps cause this:

• Revenue blindness. UA platforms don't see ad revenue, cross-store IAP, or subscriptions. They judge campaigns on a fraction of the money.
• Spend blindness. Each platform sees only its own spend. Nobody holds the whole cost line.
• Time blindness. Apple proceeds report on a T-2 delay while spend lands same-day — so any same-window comparison flatters or damns campaigns unfairly.

The fix isn't a better dashboard inside any one platform. It's moving the judgment outside all of them — to a ledger where every revenue stream meets every spend line. That ledger is what this playbook builds.

02The True ROI equation

The math is deliberately boring. That's the point — the difficulty was never the formula, it was assembling honest inputs.

03Level 1 — App: which apps deserve to exist?

The portfolio question. Once a month, put every app on one line: total revenue (all streams), total spend, net, True ROAS. Sort by net. The table does the arguing for you.

Read net first, ROAS second. High Rise's 20.2x isn't a triumph — it's near-zero spend making the ratio meaningless (that asterisk matters). Its real story is healthy organic net. Meanwhile TV Regional ES at 1.9x is the app that deserves your attention: profitable, but its spend works half as hard as the portfolio's.

The decisions this level powers: sunset apps net-negative for 90 days with a flat trend, fix monetization on apps with revenue but weak eCPM, and identify which apps have earned more UA budget.

04Level 2 — Campaign: where scale / hold / kill lives

Blended ROAS is an average, and averages are hiding places. A portfolio-level 4.57x can contain a 6x winner quietly subsidizing a 0.8x leak — and the blend will keep both running forever.

Per-campaign True ROAS puts each campaign's spend against the revenue of the users it actually delivered. Then the thresholds turn numbers into verdicts:

Attribution of ad revenue to campaigns is honest-approximate everywhere in this industry — install-cohort revenue is the cleanest practical proxy. Approximate and consistent beats precise and imaginary.

05Level 3 — Country: the hidden profit map

eCPMs vary by 10x or more across geos. So do install costs. Which means a campaign that's profitable in aggregate is almost always a mix: a US winner funding a leak somewhere else. Country-level True ROI is where that mix becomes visible.

Two moves this level unlocks:

• Shift, don't just spend. When ES revenue runs +22% against baseline for two weeks, the answer isn't "the campaign is fine" — it's move budget toward the geo that's outperforming while the window is open.
• Cap the leaks. A geo that persistently returns under 1x inside an otherwise healthy campaign gets a bid cap or an exclusion — surgical, instead of killing the whole campaign.

06The operating cadence

True ROI isn't a project; it's a rhythm. The publishers who run profitably do three reviews at three altitudes:

• Daily — 4 minutes. Net profit, anomalies, top movers. You're not analyzing; you're checking nothing is on fire and nothing is taking off without you.
• Weekly — 30 minutes. The campaign pass: every campaign against the thresholds, verdicts enforced, one experiment queued.
• Monthly — one hour. The app-level portfolio table. Sunset decisions, budget reallocation, monetization-mix review.

If the daily check takes more than a few minutes, the problem isn't discipline — it's that your data is still fragmented across six dashboards. Fix the ledger first; the cadence becomes almost free.

07Five traps that corrupt the math

1. Mixing gross with net. Store fees (15–30%) mean gross IAP next to net ad revenue overstates reality every day. One basis, everywhere.
2. Ignoring T-2. Apple proceeds arrive two days late. Compare like windows — trailing 7 days ending T-2 — or Apple-heavy portfolios will look mysteriously sick every Monday.
3. Same-day judgment. Spend lands instantly; revenue accrues over days or weeks. Judging a day-old campaign by day-old revenue kills winners early. Use cohort windows matched to your payback curve.
4. Currency mixing. Six platforms, multiple currencies, shifting FX. Normalize to one reporting currency at consistent rates or country-level ROI becomes fiction.
5. Survivor blending. Killing losers and then judging the blended average of what survived flatters the whole operation. Verdicts apply per campaign, per geo — the average is a summary, never a verdict.

08Try this Monday

Here's the honest close: you can run this entire playbook in a spreadsheet. Publishers did exactly that for years — the math doesn't care what tool computes it. What a spreadsheet costs is the 17 hours a week of pulling, pasting, and reconciling before the math can even start. AppRevBooster exists to make the ledger automatic so the decisions become the whole job. The playbook works either way — we'd just rather you spend your time on the verdicts.
