OS & Browser Version Support,So New Releases Never Break Your App
Short answer: OS and browser version support is the ongoing work of keeping an app working correctly as iOS, iPadOS, Android and the major web browsers ship new versions. It covers testing against each new release, migrating away from deprecated APIs before they're removed, raising the app's minimum target SDK to stay store-compliant, and fixing layout or behavior that changes under a new OS. Left alone, apps crash on new phones, get delisted for outdated SDKs, or render wrong in the latest Safari or Chrome. Zen in Tech tracks the platform release calendars and tests ahead of each major version so your app is ready before your users update.
Staying compatible as platforms keep moving
Mobile operating systems and web browsers are moving targets. Apple and Google ship a major OS every year plus a steady stream of point releases; Chrome, Safari, Firefox and Edge update on their own fast cycles. Each release can deprecate an API you depend on, change how a layout renders, tighten a permission, or raise the minimum SDK the stores will accept. OS and browser version support is the work of staying ahead of all of that so a platform update never turns into a support fire.
The work is both proactive and reactive. Proactive means testing your app against beta and release-candidate builds before a new iOS or Android ships, and migrating off deprecated APIs while there's still a clean path. Reactive means fixing the layout that broke in the latest Safari or the crash that only shows up on the newest Android. The common failure is discovering all of this from one-star reviews the week after a major OS drops — or worse, getting an app pulled because its target SDK fell below the store's cutoff.
We track the platform release calendars for you and keep a device-and-version test matrix that reflects where your real users actually are. Because the same in-house engineers own your codebase, we can test against betas, fix deprecations, and ship a compatible build before the new version reaches the general public.
What we cover
What OS & browser version support covers
Android version support
Keeping the app working across the Android versions your users run and raising target SDK to stay within Google Play's cutoffs.
Cross-browser compatibility
Verifying the web app renders and behaves correctly across current Chrome, Safari, Firefox and Edge, on desktop and mobile.
Deprecation & API migration
Moving off APIs and methods marked deprecated before the platform removes them, so nothing breaks when they finally disappear.
Device & OS test matrix
A maintained matrix of the OS versions, browsers and devices your audience actually uses, so testing reflects reality, not guesswork.
Store compliance
Keeping target SDK, privacy manifests and platform requirements current so the app is never at risk of removal from the stores.

How we keep your app compatible
From building a real-world test matrix to shipping ahead of each major OS, here's how a version-support engagement works with us.
1. Compatibility baseline
We review current OS, browser and device usage from your analytics and define the versions the app must support today.
2. Test matrix & tooling
We stand up a device-and-version test matrix on real devices and emulators so every supported combination is actually exercised.
3. Beta & pre-release testing
Ahead of each major iOS or Android release, we test against betas and release candidates to catch breakage before it ships to users.
4. Deprecation migration
We identify deprecated APIs on the platform roadmap and migrate off them early, while there's still a clean, low-risk path.
5. Fix, verify & release
We fix what a new version breaks, verify across the matrix, and ship a compatible build — often before the OS reaches general release.
6. Store compliance upkeep
We keep target SDK, privacy declarations and platform requirements current so the app stays listed and installable.

FAQ
OS & browser version support: frequently asked questions
How much does OS and browser version support cost?
For most apps this is folded into a monthly care plan starting around $800/mo, which covers ongoing compatibility testing and fixes as platforms update. A one-off project — for example getting an app compatible with the latest iOS or clearing a target-SDK warning from Google Play — is scoped separately, typically from about $150/hr. We confirm pricing after reviewing your app and its supported versions.
What does OS and browser version support actually include?
It includes testing your app against new iOS, Android and browser releases, fixing anything a new version breaks, migrating off deprecated APIs before they're removed, and keeping the app's target SDK and privacy requirements current so it stays store-compliant. In short, it's everything needed to make sure a platform update never breaks your app or gets it delisted.
How far ahead of a new OS do you test?
We test against the public betas and release candidates that Apple and Google ship over the summer, usually a few months before the general release in the fall. That lead time lets us catch breakage and migrate off deprecated APIs before your users update, so the compatible build is ready by launch day rather than scrambled together afterward.
Which OS and browser versions do you support?
We base the supported list on your actual users, not a generic checklist — we read your analytics to see which iOS and Android versions and which browsers your audience really runs, then support that range. Typically that means the current and previous couple of major OS versions and the current release of each major browser, but we tune it to your data.
My app was pulled or flagged for an outdated target SDK — can you fix it?
Yes, this is a common rescue for us. Google Play and the App Store both enforce a minimum target SDK, and apps below it get flagged or removed. We raise the target SDK, fix whatever the newer SDK changes or requires, test across devices, and resubmit so the app is compliant and listed again.
Do you support apps outside Houston?
Yes. We're based in Houston but keep apps compatible across new OS and browser versions for clients throughout Texas, across the USA, and internationally. All the testing and fixing happens on the codebase and on cloud device labs, so your location makes no difference to how we support you.
Do you do this for Houston businesses?
Absolutely, it's our home market. Our office is at 9800 Richmond Ave in the Westchase / Energy Corridor area, and we keep local businesses' apps working across every new iOS, Android and browser release. We can meet in person to review your app and set up a compatibility plan.
Can you support an app your team didn't build?
Yes — we regularly take over apps other teams built. We start by reviewing the codebase and its dependencies, build a real-world test matrix, and get it compatible with current OS and browser versions. From there the same engineers keep it ready ahead of each new platform release.
Ready to make sure the next OS update doesn't break your app?
Book a free call and we'll review which OS and browser versions your users run, test your app against what's coming, and put a compatibility plan in place. Care plans start around $800/mo; one-off compatibility work is scoped after a quick review.
