Your First EAS Workflow in a Rork Repo, and the Alert That Goes Missing Exactly When You Need It

Putting two files into .eas/workflows in a repo exported from Rork, and why a notification wired with needs stays silent on exactly the nights it fails — with the output of a small local checker I actually ran.

Those 14 Days of Closed Testing Are for Gathering What the Production Form Asks

Google Play production access starts from a closed test with 12 testers opted in continuously for 14 days. Here is how the count actually works, the order the tracks open in, what the application form asks, and the records worth keeping during those two weeks.

A Share Button Is Not a Social Media Capability. A Feed Makes 13+ Your Floor

The App Store age rating questionnaire now asks whether your app has social media capabilities, and answers become required in September 2026. Here is where Apple drew the line, why the under-13 escape hatch obliges you to read age ranges, and how that looks in an Expo app.

Whether You Need Rork Max Is Answered by Your Permissions, Not the Price Page

When I cannot decide between standard Rork and Rork Max, I stop reading the price page. Instead I pull every OS capability my app actually asks for out of app.json and Info.plist, then sort them into what Expo covers, what a config plugin covers, and what truly needs native Swift.

Adding .easignore stops EAS from reading .gitignore — count what actually ships to the build

EAS Build decides what to upload from .gitignore, and the moment you add .easignore the two swap places. Here is how I count the bundled files before sending, plus a measured result: once a parent directory is excluded, an exclamation mark cannot bring a file back.

Your Blended eCPM Dropped and Revenue Went Up: Splitting the Change Into Country Mix and Rate

Blended eCPM is a weighted average, not a price. Here is how I split a month-over-month change into a country-mix effect and a rate effect that reconcile exactly to the total, plus what to check before you cut a low-eCPM country.

Rork's Free Tier Gives You 35 Credits a Month, but the Number That Shapes Your Work Is 5 a Day

Rork's free plan is 35 credits per month with a 5-credit daily cap. The daily cap, not the monthly total, decides how you work. Here is how I spend those five, what I verify off-credit, and where the free tier stops.

Your Widget Extension Can Submit a BGTaskScheduler Request. It Just Cannot Register the Handler

Calling BGTaskScheduler from a widget extension compiles, submits, and returns true — and then nothing runs. Here is why registration belongs to the host app only, and how I moved refresh ownership back where it belongs across my wallpaper apps.

A Screen That Runs in Rork Companion Is Not Yet a Finished Screen

There is a gap between the app you hold in your hand through Rork Companion and the build that eventually reaches the App Store.
