Sentra
What it is
A finance app for blind and low-vision users, from opening an account to paying with QRIS.
Who it's for
Visually impaired adults who cannot finish a standard e-KYC step without borrowing someone else's eyes.
How it works
Voice guidance leads every step, the camera recognises banknotes, and each screen uses large targets with spoken feedback.
The problem
Context
Around 22.97 million Indonesians live with disabilities. For visually impaired users, most banking apps fail at the first step: e-KYC flows need someone else's eyes, so independence ends before the account exists.
What we learned first
Users didn't ask for more features. They asked not to need help: to verify identity, recognise banknotes and pay by QRIS without handing their phone to someone.
Constraints
- One month, student team
- Every screen must work with a screen reader and voice first

Project skills
- Scrum
- Scope control
As product manager
- Ran 7 stakeholder interviews and used them to set the scope
- Designed the accessible flows and the design system
- Kept the MVP to the four moments users need most
As project manager
- Led the build in Scrum sprints inside a one-month competition
- Held the team to four flows that fully worked end to end
Not my role
- Backend and ML were built by the engineers; I owned what and why
The work
Key decisions & trade-offs
- Decision 01
Scope the MVP to the moments people need help
We built voice-guided e-KYC, money detection, voice budgeting and QRIS payment, the flows where users currently depend on someone else. Hands-free AI navigation across the whole app went to the roadmap.
Trade-off A less ambitious demo, but every flow in it worked for the people it was for.
How it was built
Accessible design system (large targets, high contrast, spoken feedback), a sustainable business model for affordability, and an MVP built with the engineering team in Scrum sprints.
- Open by voiceScreen-reader first
- e-KYCSpoken camera guidance
- Know the moneyBanknote detection
- PayQRIS with audio confirmation
From the work itself
The result
- 1st
- place in a national software competition
- 4
- core flows built: e-KYC, money detection, budgeting, QRIS
- 7
- stakeholder interviews shaped the scope
What I'd do differently
Designing for screen readers made me a better designer for everyone: clear hierarchy, fewer steps, honest labels.
