Time, meet money.

Product: Solo — money & time for freelancers
Role: My concept — product thinking → UX/UI → brand
Scope: Concept · iOS design · Visual language · Data viz
Status: In development — design complete

1/ Context

Solo is my own concept, currently in development: an iOS tracker for freelancers and hourly workers — mostly young people juggling shifts, gigs and the occasional side income. They know their hourly rate; what they don't know is their real number: what today actually earned once tax is set aside and the coffee, transport and groceries are subtracted.

The ambition behind the app is bigger than tracking. It's a tool for a conscious relationship with time and money: see what an hour is really worth, watch the day's net build in real time, and learn to think in two horizons at once — today, and the long run.

2/ The concept

One number to rule the day. The home screen joins a running work timer and today's spending into a single live metric — net today: earned, minus tax, minus spent. Not the optimistic gross; the money that is actually yours.
Tax is not a footnote. A flat-rate preset is applied to every euro as it's earned, so the tax share is set aside before it ever feels spendable. The nasty spring surprise, designed away.
Friction where it teaches. No bank link — on purpose. Logging €4.80 for a coffee in two taps is the product: the small act of typing it is what builds awareness. Everything else — category chips, project rates, one-off income — is tuned to stay out of the way.
Two horizons. The same data reads as a day pulse and as a Day / Week / Month picture — where the money went, what stayed — so short-term choices and long-term habits meet in one place.
A brand that isn't a bank. Warm paper, bold geometric shapes, a lime accent and mono numerals — bookkeeping that feels like a habit tracker, not accounting software. Built for people who'd never open a finance app.

3/ Screens

Solo onboarding screen: 'Know what your hour is really worth' headline over playful geometric shapes, with a Get started button — The pitch in one line — hours, tax and spending in one place; see your real net every single day.

Solo Today screen: a running work timer, a net-today summary showing earned minus tax minus spent, quick expense entry with category chips, and today's expense list — The core loop — timer running on a project rate, net today recalculating live, and a two-tap expense entry.

Solo statistics screen: a monthly spending donut by category with earned and net totals, category breakdown and an operations list — The long view — Day / Week / Month lenses over the same data: earned, net, and where the spending actually went.

Setup that fits on one screen — hourly rate, flat tax preset, and per-project rates. Nothing to configure beyond honesty.

4/ Outcome

Solo is in development, with the concept and design complete — the brand, the interaction model and every screen are mine end to end. It's the kind of product thinking I bring to client work, pointed at a problem I care about: helping people who trade hours for money treat both as something worth counting.
