Application refactoring

Application refactoring is tidying up the code inside an app without changing what it does. Users see the same screens, but behind them the code is clearer, faster, and easier to change. It's a bit like reorganising a storeroom. Nothing new comes in, but you can find things again. For a small business, refactoring matters most when an app was built quickly, perhaps with AI tools, and now every small change breaks something else. Tidying it up first makes later changes cheaper and safer. The trade-off is that refactoring costs time without adding features you can see, so it only makes sense when you plan to keep using and changing the app.
