About this app

Buffer Builder helps you build a starter emergency fund, a small safety net that means a surprise bill doesn't have to become debt.

Most of us are one unexpected cost away from the red. A car repair, a vet visit, a power bill that lands at the wrong time. Buffer Builder gives you a simple, automatic way to set a little aside, so when life happens you can reach for your buffer instead of a credit card or a loan.

HOW IT WORKS

Set your goal. We help you pick a realistic starter target based on your income and the essentials you need to cover.

Save automatically. Buffer Builder tops up your buffer on payday, or rounds up your everyday spending, whatever suits you best.

Watch it grow. A clear, calm view of your progress, built around your pay cycle rather than a confusing spreadsheet.

Reach your goal, then set the next one. When you hit your target we help you step up to a bigger safety net, at your own pace.

WHY A BUFFER

A buffer is self-insurance. It is the difference between a stressful month and a manageable one. Even a small amount set aside changes how secure you feel, and how easily you cope when something goes wrong.

BUILT AROUND YOUR REAL LIFE

Connects securely to your bank through Akahu, New Zealand's open banking provider.

Understands your income and spending so your plan fits your actual pay cycle.

Moves money only with your explicit consent, and only into your own buffer account.

Calm, supportive design. No jargon, no guilt, no pressure.

YOUR MONEY STAYS YOURS

Buffer Builder never holds your money. Your buffer lives in your own bank account. We use bank-level security and only ever move money with your permission.

Start small. A buffer of even a few hundred dollars can keep you out of debt the next time life surprises you. Buffer Builder makes getting there simple.
