Forward-looking cashflow planner
See what your money does next.
A forward-looking cashflow app that starts with your real bank balance, applies upcoming income, bills and debt, and shows what is actually available before the next decision.
No forced bank connection. Start with your numbers and see the math yourself.
Observe less. Decide earlier.
Most budgeting apps are good at showing what already happened. Automatic transaction tracking is useful for understanding the past. Wiggle takes the opposite direction: enter what matters, see the future consequence, then decide.
A bank balance tells you what has cleared. It does not tell you how much of that money already belongs to rent, debt, utilities, subscriptions or expenses due before the next paycheck.
Wiggle Budget starts from the real amount in your account and places upcoming income and expenses on a timeline. Every entry changes the balances that follow it, making timing visible instead of hiding everything inside one monthly total.
Your balance is not your answer.
A cleared bank balance can look healthy while a large bill is due tomorrow.
A paycheck can make an account look temporarily rich even though most of it is already committed.
A purchase can technically fit inside today's cash and still create a problem three days later.
Wiggle Budget exists to expose that timing.
Interactive Demo
Try the model before using your own money.
Wiggle has a public guided demo that uses sample data and walks through budgeting workflow, cash projections and debt tools before account creation. See how the model behaves first.
| Demo | Setup | Conflict | Action | Result | Point |
|---|---|---|---|---|---|
| What can I actually spend? | Bank $2,480, seven scheduled entries | Current cash does not show what is already committed | Skip the $220 Credit Card payment | Plan and running balances react | The bank is only the starting point. |
| What survives payday? | $2,480 before payday | $1,650 paycheck makes balance $4,130 | Run the waiting bills underneath it | $2,235 survives | The peak balance was temporary. |
| Is next payday paying old spending? | $900 cash, $1,220 card balance | Current cash cannot clear the old card | Put paycheck, card and rent on one timeline | Only $130 remains | Next payday is paying yesterday. |
| What happens if I buy this? | Normal month | $2,200 trip appears affordable from bank cash | Add it as a what-if entry | Lowest point falls from $2,235 to $35 | Possible is not comfortable. |
| What changed in real life? | Known bank $2,160 | Actual bank is $2,075 | Replace one balance | End projection moves $4,105 → $4,020 | Reset reality, not the budget. |
| What happened today? | $320 Car Loan is planned | Planned does not mean paid | Mark it Done | Bank and debt move together; future does not double-count it | Mark what happened. Check what remains. Leave. |
Core Concept
Your bank balance is not what you can safely spend.
Safe to Spend asks a different question: If I spend money today, what is the lowest balance my known future reaches afterward?
That low point matters more than the current account balance because a future rent payment or debt payment may be the actual constraint. Calculated from the lowest future balance, not just today's bank account.
Future cash projection
See the balance after upcoming income and expenses.
Safe to Spend
Use the lowest future balance, not simply today's cash.
What-if decisions
Test a purchase before committing it.
Linked debt
Connect payments with the debt they reduce.
Account resets
Correct the real balance without rebuilding the plan.
Manual-first
No required bank sync. Start with the balance you choose.
Architecture
One state. Several useful questions.
The same cashflow model can answer: What will I have after the month? Where is the lowest point? What can I safely spend? Does this purchase fit? What happens if this payment moves?

Privacy & Trust
You should not need to hand over a bank login just to understand your cashflow.
Wiggle is publicly positioned as manual-first and does not require a bank connection. Start with the balance you choose to enter. Public-site analytics are consent-gated. The budgeting workspace itself is not recorded by that analytics tooling.
Real product. Real feedback.
The interactive demo shows what Wiggle is designed to do. Reviews show whether that actually matters to people using it. Positive, negative or mixed. Useful feedback is better than polished praise.

"my wife and i used to low-key argue about money all the time. not big blowup fights, just this constant low hum of 'wait did you pay that' and 'i thought you had it' and neither of us really knew where we stood. we have a joint account, my income fluctuates because of my side work, and then there's all the kid stuff that comes out of nowhere. wiggle made it so we're both looking at the same picture. the bill splitter thing is almost embarrassingly simple but it just ends the math arguments. and setting up the recurring stuff once and not having to re enter daycare and rent every single month i didn't know i needed that until i had it. our money conversations went from an hour of stress to like 15 minutes of just making sure we're good. that's real"
"I used to stress over bills constantly. Wiggle Budget helped me see the whole month before it happened. I cut back on Uber, cooked more, started saving, and even began investing. Seeing my progress made me feel more stable and confident."
"After using Wiggle Budget for a couple of months, I know exactly where my money goes and can easily spot my financial black holes. While these features are on other platforms, Wiggle Budget comes in so clutch when I need it most. I used to work constantly stressing over bills, but the dashboard projection helps me plan the entire month. I can actually budget for eating out and having fun. I am way more locked in now. I stopped taking Uber by waking up early, cut down ordering food to just once every few weeks, and try to cook as much as possible. I even started investing the money I saved. The UI is actually pretty easy to learn after a bit. Most importantly, seeing my progress gave me a huge confidence boost. I started believing in myself and appreciating my own growth."
"Amazing app! A bit of time to navigate all features and get used to it but the debt calculator really helped me see a clear picture and tackling my debt!"
