A personal finance app that never asks who you are. No sign-up, no server, no ads — just fast expense tracking, real balances and insights that are calculated on your phone.
Most finance apps ask for a login before they show you a single number. This one opens straight into your balance.
This isn't a privacy policy promise — it's an architectural fact. Sollus has no backend. Your transactions live in your device's own storage and never travel anywhere you didn't send them.
There's nothing to sign up for. Install the app and start tracking — no email, no phone number, no OAuth.
No Firebase, no Amplitude, no ad networks. The app ships without a single tracking dependency.
Android's automatic backup is explicitly disabled, so your finances are never copied to Google's servers behind your back.
Your spending is never sent to an AI service. Every score and observation is computed locally.
The app makes no network requests at all. Every screen, translation and calculation is bundled in the install, so a plane, a basement or a dead SIM changes nothing.

Waiting for a server
Pick any period and see where the money actually went. Totals, category breakdowns and trends update instantly because there's nothing to fetch.
A numeric keypad, your recent categories and a single tap to save. No modal stack, no mandatory fields, no spinner.
Income is a first-class entry type, not an expense with a minus sign. Track multiple sources and see what's actually arriving each month.
Hold accounts in different currencies, record a transaction in the one you actually paid in, and still see a single meaningful total.
Start from sensible defaults and reshape them. Categories, subcategories, icons and colours — all editable, all yours.
A financial-health score, a plain-language summary and observations about your spending — all derived on your device from your own data.
From the Latin sollus — whole, complete, unbroken. Your finances, all in one place, with nothing split off to a server you don't control. The name is the promise.
Figures describe version 1.0.0 of the Android app.
No trial, no paywall, no ads. Version 1.0.0 is out on Android — install it and your first transaction is about five seconds away.
The app is already cross-platform under the hood. An iOS build is in the roadmap, and it will land with the same rule: nothing leaves your device.
Everything you use today remains free and ad-free. Premium will add optional power features for people who want them — and it will never hold your existing data hostage.
The short answers. The full list lives on the FAQ page.
One short email a month: a practical budgeting idea, a product update, and nothing else. No tracking pixels, no partner offers.

Install it, add one expense, and see whether it sticks. There's no account to delete if it doesn't.
