Placing Native Ads in a Masonry Wallpaper Grid: Designing the Lifetime of an Ad Cell
One native ad in a masonry gallery pushed memory from 180 MB to 420 MB over twenty minutes of scrolling. Here is why cell recycling and ad object lifetime never line up, the pool-based implementation that fixed it, and how I picked the insertion interval from measured numbers.
When Your AdMob Earnings Suddenly Get Deducted: Preventing Invalid Traffic as a Solo Developer
Invalid traffic deductions in AdMob are unsettling because the cause is rarely obvious. From the perspective of running several apps solo, here is a minimal setup that prevents the most common accidents, plus how to respond when a deduction actually happens.
Protecting Ad eCPM in Your Rork Max App: Designing ATT Pre-Permission Priming
For iOS apps built with Rork Max, ad revenue swings heavily on your ATT opt-in rate. Here is how to design a pre-permission priming screen, implement it in SwiftUI, measure the opt-in rate, and order AdMob init correctly.
Don't Pay Out a Rewarded Ad on the Client's Word Alone — SSV Verification for a Rork (Expo) App on a Worker
Trusting the client-side 'reward earned' callback alone invites double-grants and spoofing. Here is how to wire AdMob server-side verification (SSV) into a Rork-generated Expo app, verify the signed callback on a Cloudflare Worker, and make payouts idempotent with transaction_id.
Monetizing a Rork-Built App — Choosing Between Ads, Subscriptions, and Freemium
How to monetize an app built with Rork — from choosing between ads, subscriptions, freemium, and one-time purchase to the implementation details. Phased AdMob formats, treating ad-free as a single source of truth, and price anchoring, written from the indie-developer trenches.
The App Privacy Section That Grows the Moment You Add Ads and Subscriptions — Notes on What I Actually Checked
How I filled out App Store Connect's App Privacy section for a Rork (Expo) app with AdMob, RevenueCat, and Crashlytics — including the tracking-to-ATT chain, written up as field notes from running six apps.
A Wallpaper App's Real Work Starts After Launch — Content, Retention, and Revenue Notes from Running One on Rork
A wallpaper app is decided less by its launch and more by how you tend it afterward. Building on a Rork implementation, here are field notes on scheduled publishing that keeps content fresh, onboarding that survives the first week, and a revenue setup whose per-download return doesn't thin out over time.
I Initialized Ads Before Restoring Purchases, and Paying Users Saw a Banner Flash — Cold-Start Ordering for Rork (Expo) Apps
Consent, ATT, ad SDK init, purchase restore, and remote config all try to run in the same few hundred milliseconds at launch. Get the order wrong and a paying user sees a banner flash, or measurement fires before consent in the EEA. Here is how I fold a Rork-generated Expo app's startup into a single orchestrator and kill the races by design.
The Day a Third Reason to Hide Ads Appeared — Folding Rork App Ad-Free Logic Into One Place
Ads show only on one screen for paying users, or ads never show for free users. The usual cause is that the condition for hiding ads is scattered across the code. Here is how I fold three reasons — subscription, lifetime purchase, and a timed reward unlock — into a single state and route every ad through one hook, written as an implementation note from running six apps as an indie developer.
Getting to the Real Revenue Number — A Pipeline that Reconciles AdMob, App Store, Google Play, and Stripe
Dashboard revenue and the money that actually lands in your account do not match. Here is an aggregation pipeline that absorbs currency, timezone, and the gap between estimated and finalized figures across four revenue sources — with the implementation and operating judgment from running six apps.
Building a Developer Debug Menu Into Your Rork App — Verify Ads, Purchases, and Remote Config Before Release
A production-safe developer debug menu for Rork apps — switch environments, force test ads, simulate entitlements, and override Remote Config, with working TypeScript code and the pitfalls I hit running six apps.
Expanding AdMob bidding demand without adding SDKs — what applying to 11 server-side partners taught me about 'enabled ≠ serving'
A working log of actually adding SDK-free, server-side bidding partners to AdMob's bidding sources: the difference between doc-type and form-type sign-up flows, how reCAPTCHA behaves, and the trap that 'partnership enabled' does not mean 'eligible to serve', told from a solo developer's point of view.
