How to make a budget tracker that doesn't judge you
~7 minutes · no code · free to start
Budget apps want to connect to your bank, harvest your transactions, and sell you a premium tier that makes the guilt graphs prettier. But budgeting that works is simpler: decide what each category gets, log what you spend, see what's left.
This one is private by design — your money data never leaves your device — and deliberately calm, because a budget you're afraid to open is a budget you'll abandon by February.
What you'll end up with
- ✓Envelopes for your categories with spent-vs-remaining bars
- ✓Three-tap expense logging
- ✓A safe-to-spend-per-day number — the one figure that changes behavior
- ✓A month-end picture of where it actually went
The five steps (same for every app)
- 1
Describe it
Type what you want in plain English — like you'd explain it to a friend. No technical words needed. Every guide below gives you a ready-made description you can use as-is or edit.

Check the plan
Kyntra replies with a short plan in plain English: what it understood and what it's about to build. If it got something wrong, just say so. Happy? Hit Approve. (You can switch on Auto later to skip this step.)

Watch it build
About a minute later your app appears in the preview panel — a real, working app, not a mockup. Click around in it right away.

Ask for changes
This is where Kyntra is different from hiring anyone: changes are just sentences. "Make it blue." "Add a delete button." "That chart is confusing, make it simpler." Each change takes about a minute, and every version gets a quality grade in the header — Kyntra checks its own work for the mistakes AI builders usually make.
- 5
Publish it
One click on Publish gives your app a real web address you can send to anyone or open on your phone. Change something later? Publish again — same address, new version.
Your ready-made description
This is the exact text the button below pastes for you — read it, edit anything, or use it as-is.
A monthly budget tracker using the envelope method. I set a monthly income and create category envelopes (rent, groceries, fun …) each with a budgeted amount. I log expenses fast: amount, category, optional note — three taps. Each envelope shows spent vs. remaining with a color bar that goes from green to amber to red as it fills. A dashboard shows total remaining this month, days left, and a safe-to-spend-per-day number. Month rolls over with one tap, keeping my categories. A simple pie chart shows where the month actually went. Calm, non-judgmental design — no red exclamation marks, money stress is bad enough.
Make it yours — things to say next
After the first build, changes are just sentences in the chat. For example:
You say: “Add recurring expenses that log themselves on the 1st (rent, subscriptions)”
→ The boring stuff, automated
You say: “Let me move leftover money between envelopes at month end”
→ Real envelope budgeting
You say: “Add a savings-goal envelope with a little plant that grows”
→ Motivation that isn't a red graph
You say: “Everything in euros, and the month starts on the 25th when I'm paid”
→ Your money's actual rhythm
Common questions
Is my financial data private?
Completely — everything stays in your browser on your device. No bank connection, no account, no server. That's more private than any budgeting app on the market.
Do I need to know how to code?
No. You describe, Kyntra builds. You never have to read or touch code — though it's all there if you're curious.
Is it really free?
Yes — free to start, no card. The free plan includes 5 apps and 25 builds a day, which is plenty to build and polish something real.
How do I know the app is any good?
Every version is audited by Kyntra's 17-check quality engine — the same kind of review a senior engineer would do — and stamped with a letter grade you can see in the workspace header.
Five minutes from now, this exists.
