Personal Accounting & Investment Tracking

Hevseng - Personal Accounting

A personal accounting app that shows income, expenses, and investments month by month on a single screen, with the same experience on web and mobile.

Hevseng is a personal accounting app built for people who keep their income and expenses as a monthly table in Excel or a notebook. Without breaking the familiar monthly layout, it calculates the totals, carries installments into the following months, and splits a credit card statement into its sub-expenses; it compares purchase cost with current value across gold, currency, stocks, and crypto to show profit and loss. It delivers the same experience on web and mobile.

Month summary updated

A single screen that takes over the manual work of the monthly table

Each month presents its Expense, Income, Investment, and Asset blocks with total rows at a glance; total expense, total income, net, and asset value are calculated automatically.

A credit card statement is split into its sub-expenses, installment and loan plans carry into later months on their own, and recurring items are suggested every month; purchase cost is compared with current value across gold, currency, BIST stocks/funds, and crypto to show profit and loss.

Value delivered

  • The monthly table kept by hand in Excel and notebooks was moved into a single app that does the calculations itself.
  • Automating installments, loans, and recurring items reduced the data entry repeated every month.
  • The cost, current value, and profit/loss of assets and investments became trackable in one place.
  • Web and mobile clients deliver an equal experience by sharing the same design system and the same backend.
