Three dark phone screens side by side on a dark grey ground: Accounts with a balance and a pastel card, Activity with a spending ring and payments, and Send money with €120 and a keypad.

Three screens, all invented

A banking app drawn to show a finished mobile design in Polyform: Accounts, Activity and Send money, each a 393 × 852 frame, the size of an iPhone screen.

Every name, merchant and amount is made up. There is no real bank, card network or logo. The screens are frames, shapes and text in Inter, with no components.

  Accounts — 393 × 852

A dark phone screen greeting Maya Kowal. A total balance of €24,806.40, up €1,240.18 this month. A lilac-to-mint card shows €8,412.75 available. Below are Send, Request, Top up and Freeze buttons, and two pockets: Rainy day and Flat 4B.
Accounts: the total balance, its cents set smaller in the same text layer; the Everyday card on a pastel gradient; four quick actions and two pockets.

  Activity — 393 × 852

A dark phone screen titled Activity, with search and four filter chips. A card shows €1,842.30 spent in October and a four-colour ring reading −8 % against September. Below, today’s and yesterday’s payments with names and amounts.
Activity: filters as chips, October's spending as a ring built from ellipse arcs, and the day's payments.

  Send money — 393 × 852

A dark phone screen titled Send money. A round avatar with the initials LM, the name Leo Marsh and a large amount, €120, with a note: Concert tickets. Below, the account it comes from, a number keypad and a light button reading Send €120.
Send money: €120 to Leo Marsh for concert tickets, from the Everyday account, with a keypad and a Send button.
