A monthly plan, not a locked report

02See the remaining amount

Frequently Asked Questions

Everything you need to know about calculating with FlexiCalc

How is FlexiCalc different from traditional budgeting apps like YNAB or Mint?
Unlike automated apps that require linking bank accounts and force you into rigid transaction rules, FlexiCalc is an open calculation pad where you draft and simulate budgets freely without bank-login requirements.
Can I reuse the same budget layout for next month?
Yes. You can duplicate any calculation page in one tap or save it to your Templates collection so you never have to retype categories.
Can I budget offline while traveling?
Everyday budget pages can be edited locally without a continuous connection. If you enable account or cloud-sync features, review their current behavior before traveling.
Does FlexiCalc support custom currencies?
Yes. You can switch between USD ($), CNY (¥), EUR (€), GBP (£), JPY (¥) and more in settings or per page.
