An implementation note from running six Rork-built iOS wallpaper apps in parallel and rebalancing interstitial fatigue with a three-layer frequency cap powered by Crashlytics non-fatal signals and Remote Config thresholds. Swift code, Cloudflare Workers config, and measured eCPM / D1 retention numbers from a four-week phased rollout.

How I added iPhone Air (420×912), 17 Pro (402×874), and 17 Pro Max (440×956) support across six apps in parallel — 29 ternary branches, a 6-app diff script, and a phased rollout that landed at zero resolution-related crashes in 14 days.
The Day I Walked Away From $730/Month — Pulling AppLovin From 5 Apps After 11 Years of Crash Data
On 2026-05-26 I paused AppLovin and AppLovinMax Bidding + Waterfall across my entire iOS/Android catalogue (50M+ cumulative downloads) for INT, RWD, and RWI. This is the full record of the three lines of evidence I used to justify walking away from $730/month and the four-week evaluation framework I set up afterwards.
Two Months of Rork × Hermes in Production — Cold Start and Memory in Real Numbers
What actually happens to cold start, memory, and crash rates after running Rork-generated apps with Hermes enabled in production for two months. Field notes from an indie developer with 50 million cumulative downloads.
Making Silent Failures Visible Across 6 Rork Apps: An Early-Warning Design Note for Non-Crash Degradation
Notes from running 6 wallpaper apps in parallel and the layer I built in 3 weeks to make Crashlytics-invisible failures observable. Beacons, timeouts, and a small Cloudflare Worker for cross-app aggregation.

A hands-on note on adding a WidgetKit Extension to a Rork-generated iOS app, with operational lessons from rolling out widgets to six wallpaper apps at once — App Group plumbing, Timeline Provider choices, memory ceilings, and ASO side effects.
iOS Foreground Notifications Disappear in Expo — A Practical Fix Guide
A focused walkthrough of why iOS silently drops push notifications when the app is in the foreground, and how to wire setNotificationHandler correctly for iOS 14+ with expo-notifications.
Two Weeks Tightening Up iPad Support for a Rork-Generated Wallpaper App
Notes from spending two weeks tightening up iPad support for a wallpaper app I scaffolded with Rork. Coming from an iPhone-centric indie practice since 2014, I cover where Rork's defaults stopped, how the AdMob adaptive banner misbehaved on iPad, and what changed in retention afterwards.
Aggregating App Store Connect, RevenueCat, and AdMob into One Morning Digest with Cloudflare Workers — A Six-App Indie Architecture
A practical architecture for indie developers running multiple Rork apps: aggregate App Store Connect API, RevenueCat REST, and AdMob Reporting API in a Cloudflare Workers Cron job and ship a single daily Slack digest each morning.

After redesigning Rewarded, Interstitial, and App Open as a coordinated 3-layer system with strict role separation and an exclusion gate, ARPDAU climbed 1.4× over nine weeks. The full playbook, code, and weekly numbers.
