About

A budgeting app built to calm, not to rush.

Sereno is an independent project. No marketing team, no ad model, no hidden paid plan. Just an app that answers one precise anxiety: not knowing where the money goes.

The manifesto

Manual, on purpose.

Every budgeting app promises the same thing: “connect your bank, we’ll handle the rest.” Sereno bets the opposite — by design, not as a missing feature.

Anxiety doesn’t come from lack of money

It comes from not knowing. The overdraft you discover too late, the “where did my paycheck go?” on the 20th, the banking app you dread opening. The information existed — somewhere in an automatic feed nobody looks at.

Full automation has a blind spot: what you don’t do yourself, you don’t feel. A charge imported silently at 3 a.m. teaches you nothing. The same expense logged by you, in five seconds, leaves a trace — in the app and in your head.

Five seconds that change your relationship with money

Logging a purchase by hand is short. But in those five seconds you know what you just spent, you choose its category, you watch it join the month. That repeated micro-gesture does what no algorithm can do for you: it puts you back in charge.

Manual entry isn’t the price of using Sereno. It’s the treatment.

What Sereno does so it sticks

  • The gesture is reduced to essentials. Amount, category, saved. Templates for what comes back often, recurring rules for what is truly mechanical (rent, subscriptions).
  • The reward is immediate. Every entry feeds the dashboard and statistics. You literally watch your money take shape.
  • No punishment. An exceeded budget shows in coral, with a calm statement. Missing three days of logging erases nothing, breaks no “streak.” You pick up again — that’s it.

Free, no trap

Everything is free forever — guest mode and sync account. No quotas, no AI, no Plus plan. If you want to support the project, it’s voluntary: a coffee, a sandwich, a boost via theSupport page.

What that implies — honestly

Sereno won’t suit everyone. If you want an aggregator that categorizes three bank accounts without lifting a finger, excellent apps exist for that. Sereno is for people who already tried — and noticed that watching imported lines scroll by never changed how they spend.
