How I framed the project at the start: the goal, the people it serves, and the limits to design within.
Working assumptions, based on the product's purpose and its screens.Evoca mobile banking app
A mobile banking app where the balance, the everyday actions and every other service each have a clear place.

- Home, services, transfers, accounts, history, contacts
A banking app is opened many times a day for small jobs: check the balance, send some money, find an old payment. So the first screen answers the common question fast, and everything else is easy to find without being in the way.
The brief.
Make everyday banking on a phone fast: see the balance, send money, find past operations and get help.
Bank customers who open the app several times a day for small jobs.
Many services to organize. Money and privacy matter. Small screens leave little room.
Who it's for.
Two proto-personas show the kinds of people the design is built for: what they want, what gets in their way, and what they need from the product.
Proto-personas come from assumptions about the audience, not from interviews. They are meant to be checked with real users.Nare, 26

Follow the journey.
The journey follows one person from start to finish. For each stage it notes what they do, what they might be thinking, and how the design answers it.

Principles behind the decisions
Privacy and control
The balance can be hidden with an eye icon, and the amounts stay blurred until the person chooses to show them.
Recognition over recall
Every service has an icon and a label, and the same icons appear on Home, Services and Accounts.
Progressive disclosure
Home shows four quick actions. Everything else lives in Services, where the Transfers group can be collapsed.
Sensible defaults
Payment details are prefilled, the balance and commission are on the form, and one switch saves a template for repeat transfers.
From problems to answers.
Each assumed problem has a specific answer in the design. The screens that follow show them in detail.
A home for the everyday, a list for the rest.
The balance leads. The available balance sits at the top with a currency switch and an eye icon to hide the amount. Four quick actions follow: My templates, Transfer to Account, Transfer to Card and Evoca Share.
Switch what you're looking at. Cards, Accounts, Deposits and Loans are four tabs on the same screen, so the list below changes without leaving Home. A promo banner and shortcuts for Rates and Crypto sit underneath.
Services for everything else. The Services screen groups all the actions as icon tiles, with nine transfer types in one collapsible group. Templates and Group payment sit at the top, and a search icon and a grid or list switch help people who know what they want.
A bottom bar that stays put. Home, Transactions, History and Contacts are always one tap away, with a round QR button in the center.


Transfers in one short form.
A sheet that rises from the bottom. Each transfer opens as a sheet with its own icon and title, so it's always clear which service you're in, and the Home screen stays right behind it.
Only what's needed. The form asks for the source account, the receiver, the sum and a short description. The account shows its balance right in the field, and the sum field shows the currency symbol before anything is typed.
Fast for repeat use. The description is prefilled, and two switches, Save the receiver and Save the template, turn a one-off transfer into a shortcut. Evoca Share sends money using a phone number, with a contacts icon in the field.
One strong button. A single full-width Transfer button sits at the bottom of the sheet.


Accounts and money tools.
Actions next to the money. Each account is a card with its name, balance and number. Right under it, Replenish, Transfer and Cash out are large icon buttons, with Details and Applications as quieter options.
An empty state that helps. With no transactions yet, the screen shows a friendly illustration and the words "No data available", and a View all link stays in place for later.
Rates and a calculator together. A Cash and Non-cash switch sits above a table of Buy, Sell and central bank rates, with a flag for each currency. Below, a currency calculator turns "I have" into "I want" and states the rate in one line.


Find it later, ask for help.
History you can filter. Past requests are listed as simple cards with a date, a name and a colored status: green for Confirmed, red for Refused and Cancelled. A search icon and a filter icon sit at the top, and a label says the list covers the last 31 days.
Help is a tab, not a hunt. The Contacts screen gives three big options, Call us, Find us and Chat with us, plus the messengers people already use. Below them, a short form lets a person send a message or request a callback, with example text in the fields to show what to write.


How I'd validate it.
These are planned tests, not results. They show how the design would be checked with real users, and what would be measured.
Task test
Ask people to send money to a phone number, and time it.
Tree test
Ask where they would look for a given service in Services.
Usage tracking
Track how often templates and saved receivers are used.
Interviews
Ask whether people hide their balance, and when.
