App Maintenance Cost

App maintenance cost is what you pay every year to keep an app working after it is launched. Most people budget for the build and stop there, and that is the mistake. Over five years the build is usually the smaller number, because an app that nobody touches does not stay fine on its own. It breaks slowly at first, and then all at once.

Start with the two stores, because they are the easiest to forget. Apple charges for a developer account every year, so if that payment stops your app leaves the iPhone store. Google charges only once, when you open the account. Both stores review the app again with every update, and both change their rules several times a year. That is why a rule you ignored in March can pull your app down in November.

Then come the phones themselves, because Apple and Google each release a new phone system once a year, usually in autumn. Millions of people install it within weeks, and something in your app almost always behaves differently afterwards. It might be a screen that will not scroll, a camera that will not open, or a login that goes round in circles. None of that is a new feature, yet you pay for it anyway. So Linkysoft tests every app it looks after on the new system before the public gets it, which is cheaper than reading about it in your store reviews.

An app also talks to a server, and that server brings a monthly bill, backups and a security certificate that expires. Someone has to answer when it stops responding at nine in the morning. Then there is the human side, which people forget entirely, from reviews that need a reply to one customer who cannot sign in. Add the crash that only happens on one cheap phone in one country. Teams who would rather not run a machine themselves put that part on Hostrena so the bill stays predictable.

A fair yearly figure is fifteen to twenty percent of what the build cost. An app built for ten thousand needs about two thousand a year to stay alive. Ask any supplier what their number covers and, more useful still, what it does not. Linkysoft puts that yearly figure inside the mobile app development quote from the start, because an owner who is surprised in year two stops paying. An app that stops being maintained quietly stops working.
