wtf is vellum-expense-tracker?

Vellum is a personal finance app for Android built around a clean, gesture based interface that is meant to make checking your spending feel fast and pleasant rather than like a chore. The main screen centers on a circular progress indicator that shows your available balance at a glance, so you can immediately see how much of your money is left to spend. The app includes a tracker screen with what it calls analytical lines and monthly filtering, which separates your all time balance from what you have spent so far in the current month, giving a clearer picture of short term spending habits versus your overall financial position. Navigation uses a minimal, icon only floating bar that sits above the rest of the interface to keep more of the screen available for content. One of the more distinct features is a home screen widget, built with Jetpack Glance, that lets you scroll through every expense from the current month without opening the app itself. The widget can be small, showing just your balance, or expanded into a fuller dashboard view. The app also supports Material You theming, meaning its colors can adapt to match your phone's wallpaper, and it offers a few custom app icon styles to choose from. According to the README, the interface design was created by one contributor while the underlying engineering, including data storage and monthly filtering logic, was built by another. The project is currently at version 26.0.1 and described as a beta release. This is a small personal finance tracking app for Android users who want a visually polished, at a glance way to watch their spending, and it currently has 2 stars. No programming language is listed for the repository.
