Pairpurse
Ours, mine and a fair rule in between — money for two, without the awkward talk.
Shared money for couples: a joint ‘ours’ budget next to private ‘mine’ spaces, fair-split rules and goal jars you fund together.
A self-initiated concept, designed like a real product.
The brief we set ourselves
Design shared finances for a couple that keeps one joint «ours» budget and two private «mine» spaces — with a split rule both partners agreed on and goals they fill together.
Who it is for
Couples aged 25–40 moving in together, planning a wedding or a flat; dual-income households where «50/50» stopped feeling fair.
What we designed
Home with the Ours / Mine split, a shared goal jar with both partners' contributions, the split-rule setup with its error state, and a transaction with «who paid» and a comment thread.
Design facts from the concept files — not business results.
02ResearchMoney apps for couples are useful. They are rarely warm.
We sized the niche, looked at how the functional leaders split bills, and set out to design the part they skip: privacy inside the couple and a feeling of building something together.

- Market
One report puts joint-finance apps for couples at $0.92B in 2025, growing to $2.67B by 2034 (CAGR 12.4%). The same page also lists much lower figures, so we treat it as a direction, not a forecast.
DecisionDesign a focused product for two — not a family budget suite and not a bill-splitter for groups.
- Gap
The leaders of the niche — Honeydue for couples, Splitwise for splitting — are utilitarian: lists, balances, settle-up buttons.
DecisionKeep the utility, add warmth: shared goals as tangible 3D jars, two partner colours that meet in every chart, friendly copy instead of debt language.
- Privacy
Sharing money does not mean sharing everything: partners want a joint view and a space only they see.
DecisionA dual balance card — Ours on light indigo, Mine on solid indigo with «Only you see this» — and a one-tap «Move €18 to Mine» from a comment.
Patterns we borrowed
- Honeydue
- Only the scenario — one shared budget for a couple; no screens or visuals audited or reused
- Bill splitters
- «Who paid / who owes» on the transaction and a single Settle up action
- Savings apps
- Goals as jars with a progress bar and a contribution history
- Chat apps
- A comment thread on a transaction, so money talk happens next to the money
What we left out
Logos, screens, copy and illustrations of Honeydue, Splitwise or any bank. Pairpurse has its own name, mark, palette and 3D renders.
Moodboard references
From a balance sheet to something you build together.
Every «before» is generated from the very same screen markup, reduced to outlines, readable labels and grey word-bars — no colour, 3D or glass. Drag a handle to compare.

Hierarchy
Ours vs Mine first, then how the month is going, then the nearest goal — the three questions a couple actually asks.
- 02
Two colours, two people
Sam is indigo, Alex is coral — in contributions, the split slider and every chart, so «who» is readable without a legend.
- 03
States
Mine hidden / shown, the split slider while dragging, an empty income field that disables Save with «Add Alex's income», settled and unsettled debts.
- 04
Assets
Three 3D renders made for the concept — the home scene of two jars and coins, the travel jar, the flat jar. No stock photos of happy couples.
- 05
Glass, measured
White 58% glass with 32 px blur over the scene; muted text darkened to #3A374E on glass. Worst pixel under any text: 4.77:1.

Real-looking data
Rent split 57/43 by income, round-ups from Mine, a grocery receipt and a thread about who pays for the wine — tested with real lengths.
Indigo for trust, coral for the two of you.
Indigo carries every action (8.4:1 with white text) and stands for the steady, shared part; coral is the warm partner colour at 2.13:1 — for fills, the second person and the FAB, never for text. Bricolage Grotesque gives headlines character, Figtree keeps numbers calm.
A purse dome built from two halves — indigo and coral — with a clasp of two rings: «purse» and «pair» without a single letter. Picked from four sketched directions; reads at 24 px.

Four screens about money, written like a conversation.
Home · glass
The Ours / Mine card, glass cards for spending together over the last 12 weeks and the Lisbon goal, a glass tab capsule and a coral «Add money» button over the 3D scene.
Shared goal jar
The travel jar on a coral gradient, progress split by partner, the auto-adds and round-ups that fill it, and the next goal waiting below.
Split rule · error state
50/50, by income or custom: the slider shows 57/43 with an example on the rent — and refuses to save until Alex's income is filled in.
Transaction
Who paid, each share, «You owe Alex €49.25 · Settle up» and a comment thread that can move part of the bill to Mine.
Split slider
Two partner colours meet at the thumb; the example under it makes the rule concrete.
Money talk in place
A comment becomes an action: «Move €18 to Mine» edits the split.
Component sheet
Logo, dual balance card (default / Mine hidden), goal jar as a row and as glass over 3D, split slider in three modes plus dragging, monthly bar chart, avatar pair and balance chips, buttons, inputs with error and the segmented control.

Questions & answers
Is Pairpurse a real product?
No. Pairpurse is a self-initiated concept by Omnisense — a brief we set ourselves, with no client and no business metrics. All people, amounts and shops in the screens are sample data.
Who is Pairpurse for?
Couples aged 25–40 moving in together, planning a wedding or a flat, and dual-income households where «50/50» stopped feeling fair.
How does the Ours / Mine split work?
A couple keeps one joint «ours» budget and two private «mine» spaces. A split rule both partners agreed on — 50/50, by income or custom — divides shared costs, and the balance card shows Ours next to a Mine that only you see.
What did you design?
Four key screens: home with the Ours / Mine split, a shared goal jar with both partners' contributions, the split-rule setup with its error state, and a transaction with «who paid» and a comment thread — plus a component sheet, logo, palette and type system.
Is it based on an existing couples app?
Only the scenario of the niche. No logos, screens, copy or illustrations of Honeydue, Splitwise or any bank were used. Pairpurse has its own name, mark, palette and 3D renders.
