The brutal truth
You have a visibility problem.
You've seen the pay go in. You've felt the panic when it's gone. You just don't know exactly where it disappears — and that's the gap GYST closes.
Upload your bank statement. See every pattern, every leak, every bad habit — quantified. Not estimated. Exact.
The GYST philosophy
Most people manage their money on feelings. GYST forces you to manage it on facts. There's a difference — and it shows up in your account balance.
Not estimates. Not averages. Exact numbers from your actual transactions — automatically.
Drop your CSV bank statement and GYST processes every transaction automatically. No manual entry. No spreadsheet. Full picture in under a minute.
CommBank · ANZ · NAB · Westpac · INGEvery transaction is automatically mapped to a category. Add your own keyword rules and GYST applies them instantly — retroactively across all uploads.
Learns your habitsGYST surfaces the money that slips through the cracks — subscriptions you forgot, habits you underestimate, big purchases you rationalised.
The $4k the average user findsMonthly tabs, year views, category filters. See exactly how your drinking spend trended over 12 months. How your dining habits compound into real money.

Keyword rules · custom categories · recategorise on the fly“I've used every budgeting app going. GYST is the only one that made me genuinely uncomfortable with my own patterns. Three months in, I'm saving more than ever.”
“When I saw my 'subscriptions I forgot about' category I was genuinely ashamed. Cancelled 9 things in one sitting. That's $220/mo I just got back.”
“I knew I was spending too much on dining out. I didn't know it was $780 last month. Seeing the exact number is a completely different experience from knowing it's 'a lot'.”
The cost of GYST is nothing compared to another year of not knowing where your money goes.
Every month you don't know where your money goes is a month your future self is paying for.
