What's done.
What's next.

K-Id is built in public. This is the honest list — what exists, what is being built, and what will not happen in v1.

Financial calculator with PMT, algebra & currency

Inline expressions, loan instalments, equation solver, memory slots, live FX rates.

Budget charts & analysis (5 chart types)

Monthly evolution, budget vs actual, donut, balance sheet gauge, equity dynamic indicator — all with thumbnail preview.

Agenda, recurring payments & alarms

Monthly/annual scheduling, future-dated transactions, sound alarms, calendar with event markers.

Asset depreciation & inventory

Fixed asset register, linear depreciation, automatic accounting entries.

PDF / Print / Mail outputs

Financial summary & tools

Automatic daily backups

PT / EN language toggle

Full interface translation at runtime, no restart required.

Export to Excel or CSV

Download your transactions and reports as a spreadsheet or CSV file — ready to open in Excel or share with your accountant.

Account reconciliation

Match your ledger against bank statements.

Linux version

Native Linux build currently in development.


K-Id is built by one person, for people who want to understand their money — not be managed by an app that understands it for them. It will never do everything. It will never have a roadmap driven by investors. It will never show you ads or sell your data.

If that trade-off works for you — welcome.

— Built in the evenings. Tested on real money.
