The headline

In 2026, attribution is no longer “pick an MMP and you’re done”. On iOS, you live with aggregated, delayed signal and threshold effects. On Android, you still get more deterministic signal, but it’s a mistake to assume that will last.

The practical takeaway is boring (and correct): build a layered measurement stack so one platform announcement does not nuke your ability to steer budgets.

What Moburst argues changed

Key claims and framing from the piece:

• iOS: SKAN got superseded by AdAttributionKit (AAK). Whether you call it SKAN or AAK internally, the operational reality is the same: postbacks, windows, and privacy tiers, plus more knobs and edge cases.

• Volume thresholds are the hidden tax. If you run lots of small “test” campaigns on iOS, you can fall below the privacy thresholds and get weak or suppressed conversion signals. Their point is blunt: low-volume iOS tests can be directionally wrong.

• Android: Privacy Sandbox is dead, GAID is still around (for now). They treat that as a temporary window: don’t waste it. Use Android’s richer signal to learn faster, but build privacy-first measurement at the same time.

Why this matters (for app growth teams)

A few practical implications worth pulling out:

• Optimization loops slow down when signal is delayed and capped. If the data comes back late, in aggregate, and only above thresholds, you need to adapt pacing, experiment design, and expectations. “Tiny budget test” is often just paying for uncertainty.

• Your ‘single source of truth’ has to reconcile multiple imperfect streams. Platform postbacks (iOS), deterministic Android events, MMP modeled outputs, and backend revenue often disagree. You need a reconciliation habit, not a perfect dashboard.

• Incrementality becomes the adult in the room. When user-level paths are noisy, you win by answering: “Did this spend change outcomes?” rather than “Which click caused this install?”

A simple checklist you can steal

If you want a minimal, non-overengineered 2026 stack:

1. Implement AAK/SKAN cleanly on iOS, then stop pretending you can do micro-tests at tiny volume.
2. Use an MMP as a reconciliation layer, not as a magical truth machine.
3. Instrument first-party events server-side (activation, paywall view, trial start, renewal, refund), so you can sanity-check “modeled” numbers.
4. Run at least one incrementality test per quarter on your largest channel.
