Keeping a virtual account is great way to forego cumbersome cash transfers or handing over physical money. Instead, you keep track how much money you have advanced for someone else until, finally, you settle the account after many transactions.

This app provides for such virtual account. It also adds some further funtions for convenience.

Note that the only purpose of this app is to keep track of transactions without having to settle the account after each of them. No measures of establishing trust (e.g., proofs) are included. Hence, only use the app when trust is pre-established.

Trivia

• Visual design: Heavily leans on the Commodore 64 with its fixed palette and fixed-width font. Still, some liberties have been taken:
  • The font is rounded, instead of being based on a 8x8 pixel array.
  • Small characters are averted as, back in the days, that meant that "drawing" characters were not available any more. However, they are still used occasionally (e.g., hints).
  • Visual elements are not placed within the block matrix, like the 40x25 matrix of the Standard Character Mode.
  • Dark green has been added as one further color (the 17th) for consistent coloring within the VIEW ALL ACTIVITIES screen.
• No permissions needed: As seldom as this might be in 2024, the app only needs the SharedPreferences (and nothing else).
