New OS versions every year – what does it require?

An app isn’t a product you build once and finish. iOS and Android release new versions every year, and the ground under the app keeps shifting. Many buyers budget for the build but forget the ongoing upkeep needed just to keep the app working. Here’s the annual cycle you need to plan for, and why it deserves its own line in the budget.

The stores’ target-version requirements – and what happens if you fall behind

Both Apple and Google require new uploads to be built against a reasonably recent OS version. On Android that’s expressed as a minimum target API level, on iOS as an equivalent SDK requirement. The requirement rises every year, roughly a year after a new OS version ships.

The consequence of staying on old versions is concrete and unglamorous: if the app doesn’t meet the requirement, you can no longer publish updates. You can’t fix bugs, can’t patch security holes, can’t add anything. Existing users may keep the app for a while, but it becomes a frozen ship you can no longer steer. Getting out of that situation usually requires a bigger technical overhaul, more expensive than if the app had been kept current all along.

An annual cycle for technical compliance

Maintenance becomes manageable if it’s planned as a recurring cycle rather than a surprise every fall. Roughly, the year looks like this:

The core is summer testing. Once the beta versions are out, the team can run the app against them and catch what would otherwise have hit all at once as millions of users update in October. That turns the fall release from a fire drill into a planned item on the calendar.

A worked example

Say you launched an app two years ago and then left it alone. It still works, until a user with a new phone reports that login crashes. You look into it and discover that the authentication library is no longer supported, that the app also falls below this year’s target-version requirement, and that you therefore can’t even upload a fix without first upgrading several underlying pieces. What could have been a few hours a year has become a multi-week project. The point: technical compliance is cheap when ongoing and expensive when postponed.

Its own budget line, separate from new development

The most common mistake is lumping maintenance and new development into the same pot. Maintenance then loses every time, because new features always feel more urgent than keeping what already exists running. The result is an app that slowly falls behind until it suddenly can’t be updated at all.

So keep two things separate in the budget. Technical compliance keeps the app working on new OS versions and devices, the user rarely notices anything, and that’s the whole point. New development adds value on top. A common rule of thumb is to budget 15-25 percent of the original development cost per year for ongoing maintenance, of which compliance is a part. Giving it its own line makes sure it actually gets done.

What actually stops working if you wait

The abstract idea of “the app falling behind” gets clearer with examples of what actually breaks. Permissions and privacy rules tighten almost every year, a new OS version might require the app to request access in a new way, and if it doesn’t, a feature stops working. Third-party services for payment, maps, or login update their libraries, and an app that doesn’t keep up loses that functionality. New screen sizes and devices can break the layout if the app was built against yesterday’s formats.

None of this happens on launch day. It creeps in, piece by piece, until enough has broken that a user reaches out, and by then the issues are often several at once. That’s exactly why steady, planned compliance is cheaper than waiting until something forces a big overhaul.
