Ooba · Financial App · Home Loan Calculator
Buying a home is one of the most significant financial decisions a person makes. The app needed to support that — not just calculate it.
The problem
The existing experience gave users a monthly repayment figure and nothing else. No context around what that number meant in practice, no way to model alternative scenarios, and no clear next step. Users left the tool and continued their research elsewhere — often returning multiple times without ever feeling ready to act.
The goal: Design a mobile app that builds genuine confidence through the home loan journey, from early affordability exploration through to pre-approval.
Survey
An online survey with 60 first-time buyers mapped the full research journey — where people started, what confused them, and how many tools and sources they moved between before feeling ready. Most were using four or five different resources across multiple sessions, which indicated that no single tool was doing the full job.
Usability testing
Remote usability testing on the existing calculator through Maze — 12 participants, unmoderated, with screen recordings — was the most revealing part of the research. Every participant retrieved their repayment figure and then navigated away. The tool was answering the calculation question, but not the underlying one: can I actually do this, and what should I do next.
A teardown of six comparable tools across local and international providers scored each on confidence-building, scenario flexibility, and clarity of next steps. That analysis defined the specific gaps to close.

Key features
Affordability calculator with real-time breakdown, deposit impact modelling, side-by-side scenario comparison, implementation cost estimates, and a single pre-approval CTA that closes the flow with a clear next step.
Numbers
A mobile app that takes someone from "I wonder if I could afford a home" to a pre-approval application, with enough clarity along the way that the decision feels considered rather than rushed.

Design system
Sliders over text fields wherever the input is a range — the interaction feels exploratory rather than prescriptive, which matters for users in an anxious decision-making state. Colour used with intention: green for a comfortable affordability range, amber as a stretch indicator. Advanced inputs — bond registration costs, transfer duty, insurance estimates — available behind a toggle for users who want the full picture, without cluttering the primary experience.
