Calm personal budgeting

See your money clearly, without the anxiety.

You log your spending by hand, in two taps. Sereno shows you where your money goes — calmly, with no red alerts and no guilt. It works right away: no account, straight on your device.

Free. No sign-up. No bank connection.

Local first

Your data lives on your device. An account only matters if you want to sync several devices — and it's free.

Manual, on purpose

No bank connection. Logging an expense yourself takes five seconds — and that very gesture is what puts you back in charge.

Never an alarm

Going over budget isn't a fault. Sereno states it calmly, in amber, never in red — and helps you adjust next month.

Features

Everything you need to see clearly. Nothing to rush you.

  • Two-tap entry

    Amount, category, done. Reusable templates for the expenses that keep coming back.

  • The strata

    Your month's spending as layers of sediment: the biggest expense forms the bedrock. One glance is enough.

  • Gentle budgets

    Per category or global, weekly to yearly, with an honest end-of-month projection.

  • Calm statistics

    Net worth, month-over-month comparisons, spending days — facts, not judgments.

  • Recurring & installments

    Rent, subscriptions, payment plans: generated automatically, never forgotten.

  • Offline, installable

    A full PWA: on your phone like a native app, with or without a network.

The method
“Financial anxiety doesn't come from a lack of money — it comes from not knowing. Five seconds of mindful entry beat an automatic bank feed you no longer dare to open.”
