Features

Everything you need to see clearly.

Sereno deliberately does less than the others: no bank connection, no pushy notifications, no score. What remains is carefully made.

Log, without friction

Two-tap entry
Amount, category, saved. Today’s date and your usual account are pre-filled. A note or a color marker if you want — nothing is mandatory.
Transaction templates
The morning coffee, the tank of fuel: pin your recurring expenses and replay them in one tap.
Receipts
Attach a photo of a receipt to a transaction to find it again later.
Transfers between accounts
A transfer is neither income nor an expense — Sereno handles it correctly, on both sides.

See, at a glance

The strata
Sereno’s signature: your month’s spending drawn as layers of sediment. The biggest expense forms the bedrock; each layer’s thickness is its share of the total.
Calm statistics
Category donuts, net-worth curve, cumulative balance, a heat calendar of your spending days. Facts, never judgment.
Month comparisons
“+€120 vs last month” — stated simply, so you can adjust without drama.
Calendar
Your transactions laid out over the month, connecting spending to the real days of your life.

Frame, without punishing yourself

Budgets per category or global
Weekly, monthly, quarterly, yearly, or a custom period. With an honest end-of-period projection, computed from your actual pace.
Overruns are amber, never red
“€50 over — it happens.” An overrun is a fact stated calmly, not a fault to atone for.
Automatic recurring rules
Rent, subscriptions, salary: recurring rules generate the transactions on their own — and even catch up on missed occurrences.
Installment plans
Paying in three installments? Sereno tracks each one and shows what’s left to pay.

Everywhere, at your pace

Works without an account
Guest mode is complete: transactions, budgets, statistics, calendar — everything, locally on your device, zero setup.
Optional free account
When you want to sync several devices: multiple accounts, custom categories, server-side recurring rules. Your local data migrates automatically, nothing lost.
Installable and offline
A real PWA: add it to your home screen, browse and log even without a network.
Export your data
Full backup and CSV export in one tap. Your data is yours — including the day you leave.
