I need a lightweight Android app called “Daily Ledger” that lets office workers and seniors quickly log daily expenses without the complexity of a full finance app. The flow should be simple: type an amount, pick a category from chips, and save; show entries in a chronological list. Keep the UI clean with an attractive header and a gradient FloatingActionButton. The app must work offline and store data locally (use Room). Amounts and currencies must display correctly for the user’s locale, and all labels and category names should be fully translated into zh-CN and ru-RU. Build it in Kotlin using an MVVM approach, XML layouts, and RecyclerView, targeting Android (min SDK 31, target SDK 32).
