Cashbook — cash management
A deliberately minimal mobile app: record every bit of money in and out in seconds, and know where the cash stands at any moment.
The context
Keeping day-to-day cash does not call for accounting software: what you need is a reliable place to note money in and money out, with no friction — including offline.
Our answer
We cut the app down to the essentials: two taps to record a movement, customisable categories, a balance that is always visible, and local storage that works without a network. Everything else — history, filters, export — stays in the background so entry never gets heavier.
Key features
- Money in and out recorded in two taps
- Running balance always on screen
- Customisable categories
- History filterable by period
- Local storage, usable offline
What it changes
- Cash kept up to date as it happens, effortlessly
- No dependency on the network
- An interface anyone can use
