Three bugs came out before we had a green run, and all three were in our own tooling. What they were and what we changed.https://shipvo.dev/blog/ota-updates-and-the-app-store-rules/https://shipvo.dev/blog/ota-updates-and-the-app-store-rules/Sat, 31 Oct 2026 12:00:00 GMTBoth Apple and Google allow some code to change after review, and neither allows all of it.

The numbers, the 28-day window that makes a bad release expensive, and what a simulator can and cannot do about it.https://shipvo.dev/blog/slow-brittle-expensive/https://shipvo.dev/blog/slow-brittle-expensive/Sat, 31 Oct 2026 12:00:00 GMTMartin Fowler's test pyramid says to run few tests through the UI because they are slow, brittle and expensive. That advice still holds. Here is how to use a simulator without breaking it.https://shipvo.dev/blog/accessibility-is-your-test-interface/https://shipvo.dev/blog/accessibility-is-your-test-interface/Sat, 31 Oct 2026 12:00:00 GMTThe labels that let a screen reader user find your button are the same ones a test, or an AI assistant, uses to find it. Why that is a good thing to build on, and what it cannot replace.https://shipvo.dev/blog/wait-do-not-sleep/https://shipvo.dev/blog/wait-do-not-sleep/Sat, 31 Oct 2026 12:00:00 GMTA test that sleeps for a second is a test that fails on a slow day. Wait for what you expect to see instead, and make the failure message tell you what the screen actually showed.https://shipvo.dev/blog/mobile-money-is-the-checkout/https://shipvo.dev/blog/mobile-money-is-the-checkout/Sat, 31 Oct 2026 12:00:00 GMTMobile money moved more than two trillion dollars in 2025, and most of the growth came from Sub-Saharan Africa. If your app takes payments there, the failed payment is not an edge case. How to test it without moving real money.https://shipvo.dev/blog/building-for-the-2gb-phone/https://shipvo.dev/blog/building-for-the-2gb-phone/Sat, 31 Oct 2026 12:00:00 GMTEntry-level Android phones are the default in much of the world, and Google builds a whole edition of Android for them. What an over-the-air update costs on one, in kilobytes and milliseconds, measured on a real phone in Douala.https://shipvo.dev/blog/staged-rollouts/https://shipvo.dev/blog/staged-rollouts/Sat, 31 Oct 2026 12:00:00 GMTApple and Google both let you release to a fraction of users first, and they do it differently. What each gives you, and how Shipvo's cohorts apply the same idea to over-the-air updates.https://shipvo.dev/blog/who-signs-your-updates/https://shipvo.dev/blog/who-signs-your-updates/Sat, 31 Oct 2026 12:00:00 GMTAn over-the-air update is code arriving from a server. Code signing is what lets a phone refuse it if it was tampered with. How Expo's code signing works, how Shipvo does it, and the trade-offs of each.https://shipvo.dev/blog/what-mcp-is-and-why-your-app-might-speak-it/https://shipvo.dev/blog/what-mcp-is-and-why-your-app-might-speak-it/Sat, 31 Oct 2026 12:00:00 GMTThe Model Context Protocol lets AI assistants use tools and data in a standard way.

How to test the no path before your users find it.https://shipvo.dev/blog/test-airplane-mode/https://shipvo.dev/blog/test-airplane-mode/Sat, 31 Oct 2026 12:00:00 GMTAndroid's guidance on offline-first apps starts from a plain fact: connectivity comes and goes. How to test the moments your app has no network, and what a simulator can and cannot show.https://shipvo.dev/blog/a-codepush-alternative-after-app-center/https://shipvo.dev/blog/a-codepush-alternative-after-app-center/Sat, 31 Oct 2026 12:00:00 GMTMicrosoft App Center shut down on March 31, 2025, and CodePush went with it.
