What Does It Really Cost to Maintain an App After Launch? 🔧

Most founders spend weeks getting comfortable with what it costs to build an app. Then it launches, and a new set of bills shows up that nobody budgeted for. That isn't a sign something went wrong. It's just how software works: a successful app is never really finished, it's maintained over the longterm so your users can continue to enjoy it for years to come.

Why Launch Day Is Just the Start

Building an app and running an app are two different jobs with two different price tags. If you haven't seen it yet, our breakdown of what it typically costs to build a mobile app covers that first number. The maintenance cost is the second, separate budget. It covers keeping your app working, secure, and useful once real users start relying on it. Skipping this second budget is one of the most common, and most avoidable, surprises founders run into after launch.

A Simple Rule of Thumb for Budgeting

A question we hear often is how much founders should actually set aside for this. As a general rule of thumb, we recommend budgeting around 10% of your original project cost, annually, just to maintain the existing software. That covers things like keeping libraries up to date, patching server operating systems, and other routine upkeep that has nothing to do with adding new features. It's not a hard rule for every project, but it's a solid starting point for planning ahead instead of getting surprised later. If you are planning to be adding some additional features as time passes maybe budget an extra 30% of your original budget towards sustained future updates. Then for clients of ours that want to be rapidly improving their existing project its possible that the first version ends up being a small percentage of their overall spend because they consider expanding features, growing into a new platform like Web if they only did Mobile to start, or even changing all the original features based on clients feedback. It depends on how much work you need done.

Hosting and Infrastructure

For most of the projects we build, we host on DigitalOcean or AWS, depending on the app's scale and needs. DigitalOcean tends to be a great fit for straightforward apps that need predictable, affordable pricing. AWS makes more sense once you need more advanced services, like specialized storage, machine learning tools, or infrastructure that needs to scale quickly with demand. Either way, hosting isn't a one-time purchase. It's an ongoing monthly cost that scales with your traffic and usage, and it's the foundation everything else runs on. If you haven't locked in your stack yet, our guide to choosing the right technology stack for your project walks through how that decision affects hosting down the line.

Bug Fixes and Stability

Even a well-built app will hit bugs once real users start clicking around in ways your team didn't test for. Budgeting for ongoing QA and bug fixes means small issues get caught and resolved quickly, before they turn into bad reviews or lost customers. If you ever find yourself doing some of that troubleshooting on your own, our guide to troubleshooting mobile apps and websites walks through a calm, step-by-step way to track down what's actually going wrong.

Keeping Up with OS and Platform Updates

Apple, Google, and web browsers push updates constantly, and they don't wait for your schedule. An app that isn't kept current with these changes can slow down, break, or even get pulled from the app stores. Ongoing maintenance includes testing against these updates and making the small adjustments needed to stay compatible.

Feature Updates and Small Improvements

There's a difference between keeping the lights on and actually growing your app. Small, ongoing improvements based on real user feedback are what keep an app useful and competitive over time, rather than letting it quietly go stale.

Security and Data Privacy Upkeep

Security isn't something you set once and forget. Patching vulnerabilities, monitoring for unusual activity, and keeping dependencies up to date all protect both your users' data and your reputation. This way nothing falls through the cracks as time passes.

If you're planning a new app, or you already have one and aren't sure what ongoing maintenance should look like, we're happy to walk through it with you.
