I kept running into the same planning problem: a monthly budget doesn’t line up neatly with weekly or fortnightly pay, especially when annual and quarterly bills are mixed in.

The method I’m building around is:

1. Map income and recurring commitments to their actual dates.

2. Work out what needs to be set aside on the next payday.

3. Look ahead across 13 weeks for bills that are underfunded.

4. Keep savings, debt payments and “safe to spend” visible in the same plan.

I’m building Harbourline for Australian households. It’s AUD-first, account-based, and includes household sync, exports and optional one-way Google Calendar sync. It does not use bank credentials or provide financial advice.

I’m running a small A$1/week early-access beta and would value feedback from other Australian builders on the onboarding and product direction.

Founder here — I’m excited to finally launch Harbourline.

After a rough stretch financially and changing employment, I realised I couldn’t find a simple, visual planner that worked with the way my ADHD brain handles money. Most budgeting tools I tried felt like spreadsheets or reports. I wanted something that answered a more practical question: after the bills, savings and debt are accounted for, what can I safely spend before the next payday?

So I built Harbourline, a visual payday planner for Australian households. It lets you plan around weekly or fortnightly income, see upcoming bills on a 13-week forecast, set aside savings and debt repayments, and share a household plan. It defaults to AUD, with other currencies on my list if there’s enough interest.

It’s live now at A$1/week as an introductory price. Anyone who signs up and stays active keeps that price even if it changes later.

I’m proud of getting this out the door and would really value feedback from other founders:

\- Does the value proposition make sense in the first few seconds?

\- Which part of the planning flow would you want to see explained better?

\- What would make you trust a new personal-finance tool?

I’m the founder, and this is my product. It’s a planning tool, not personalised financial advice.

Hi everyone, I’m Grant, the person behind Harbourline.

I’ve just launched it after a rough stretch financially and a change in employment. I kept looking for a simple, visual way to see what was happening between paydays, but most of what I found either felt too complicated or didn’t suit the way my ADHD brain works.

So I built the thing I wanted, and I’m genuinely proud to have it live.

Harbourline is made for households paid weekly or fortnightly. It defaults to AUD and helps lay out bills, spending, savings and debt across a 13-week view, then shows what’s planned before the next payday.

It’s live now at an introductory price of A$1 per week. Anyone who signs up at that price and remains active keeps it, even if the price changes later.

If you’ve built or launched a side project, I’d love feedback on the landing page and first-run experience. What would you want to understand before trying a planner like this?
