Paywalls get free personalization · Google Play set memory rules

Google Play is enforcing new thresholds for dynamic memory and bitmap usage to prevent app terminations. Developers can now use on-device foundation models to personalize paywall copy for free, while Apple scheduled its next iPhone launch event for September 9.

🎙 Podcast Mobile Dev Memo Podcast Season 7, Episode 30: MDM Mailbag #8 (with Thomas Petit)

Key takeaway: Thomas Petit claims 80% of MMM vendors are simply repackaging open-source tools like Google’s Meridian or Meta’s Robyn rather than building original models.

• Ad networks require deterministic user-level data for auctions, meaning incrementality testing cannot fully replace traditional attribution methods.

• Technical "blunders" like duplicate events or incorrect optimization signals are found in 99% of client accounts during initial audits.

• TikTok organic distribution is the most effective starting point for spends under $5,000 to identify winning creative angles before moving to paid Meta campaigns.

• Web-to-app flows are best suited for high-complexity categories like health or fintech, while gaming and photo editors should stay direct-to-store.

• Chargeback rates exceeding 20% will trigger enforcement actions from payment providers and platform owners.

• Meta's algorithm identifies interested users faster than Google or AppLovin for early-stage paid testing.

Why it matters: This provides a framework for auditing data flow and scaling user acquisition from zero for subscription apps.

• ▶ YouTube My First Million $5B founder: How I automate my entire work with AI (3 tutorials)

  Key takeaway: Zapier CEO Wade Foster maintains a $5 billion valuation with only 730 employees by using "deterministic" AI agents to handle business logic and executive administration.

  • $5 billion valuation was reached after raising only $1.3 million in primary capital total.

  • Deterministic workflows using code logic are preferred over purely "agentic" guessing to ensure AI reliability and prevent token waste.

  • The "Scout" agent summarizes calendar and email priorities at 6:00 AM to identify the single most important task for the day.

  • End-of-day admin tasks were reduced from 2 hours to 15 minutes by using AI to summarize meeting notes and draft follow-up emails.

  • A "7-person War Council" of AI personas, including a "Wartime COO" and "Ruthless CFO," is used to scrutinize every job offer and major decision.

  • System prompts are configured to demand direct honesty and disagreement to avoid the "CEO echo chamber."

  • Hiring filters are simplified to two criteria: evidence of exceptional ability and creative chemistry.

  Why it matters: It demonstrates a blueprint for scaling revenue without the traditional overhead of a massive headcount.
