Free. Coming to iPhone and Android.
The budget tracker you'll actually keep using.
Three seconds per expense. No sign-up, no bank login.
Every budgeting app dies the same way. You log everything for nine days, you miss one, and you never open it again. Wumbi takes three seconds, so there's nothing to fall behind on. Type the amount, tap Income or Expense, done. No sign-up, no bank login, and it works with no internet at all.
One email on launch day. No newsletter, no spam.

Built for one thing
Log an expense in under three seconds.
You're standing at the till with your phone in one hand. Open Wumbi, type the amount, tap Expense. It's saved, and the screen is already waiting for the next one. No confirmation screen, no category picker, no “are you sure”.
1
A numpad that answers before you lift your finger
The haptic fires when you touch the key, not when you let go. It sounds like a detail until you've typed twenty of them.
2
One tap and it's saved
Income, Expense or Transfer saves immediately. There's no Save button because there's nothing left to confirm.
3
Type in any currency, pay from any wallet
Type an amount in euros, pay from a dollar wallet. Wumbi converts it and keeps both numbers, so your history doesn't rewrite itself next month.
What's in the free app
Eight things your finance app should have done years ago.
One tap to log
Income, Expense or Transfer saves instantly and the screen stays open. The fields clear themselves, your wallet and currency stay exactly where you left them.
Tags instead of categories
Type #coffee #trip #work as you go and the tags create themselves. Nobody has ever enjoyed maintaining a category tree, so Wumbi doesn't have one.
64 currencies, crypto included
Sixty-four currencies, plus Bitcoin, Ethereum and USDT down to 8 decimals. Every wallet keeps its own, and your total converts to whichever one you want to think in.
Your money stays on your phone
Nothing to sign up for and nothing uploaded. Your transactions sit in an AES-256 encrypted database on the phone itself, with the key in secure storage. One tap wipes all of it.
Subscriptions you forgot about
Set anything to repeat daily, weekly, monthly or yearly and it becomes a subscription you can pause, edit or kill. The monthly total sits at the top, which is usually the uncomfortable part.
Charts you'll actually read
Income against expense by month or by year, a trend line, and your spending broken down by tag. Look at everything at once or narrow it to one wallet.
Search every transaction
Find anything by description, amount, wallet or tag, then filter and sort the whole history.
Works with no internet
Rates are cached on the phone for 12 hours and every transaction remembers the rate it was made with. Planes, metros, foreign SIM cards, none of it matters.

Tag map
See which tags are quietly eating your month.
Every tag becomes a bubble. The bigger it is, the more money went through it, and a line means those two tags keep showing up on the same transaction. Pinch it, drag it around, tap one to open it.
The map arranges itself
The bubbles find their own positions. Push one and the rest get out of the way.
Spent, earned and net for every tag
Open any bubble to see its transactions across every wallet you have.
Try it. Drag a bubble on the phone.
Your monthly budget, in one screen
See where the month actually went. No spreadsheet, no formulas.
Income against expense for the last six months or the last six years, this period next to the one before it, a trend line, and your spending split by tag. Point it at one wallet or all of them. You get the monthly and weekly view a budget planner spreadsheet gives you, without opening a spreadsheet.

FAQ
What you're probably about to ask.
Account, price, privacy, offline, currencies. All of it answered before you download anything.
Do I need an account or a bank connection?
No. There's no sign-up, no email and no password, and the free app never asks about your bank. If you'd rather have automation, premium can connect your bank so transactions arrive on their own, but that's a switch you flip, not a step you're forced through.
Where is my financial data stored?
On your phone, in an AES-256 encrypted database whose key lives in the device's secure storage. On the free plan nothing is uploaded anywhere, because there's nowhere to upload it to. If you turn on premium backup, that's the only time anything syncs, and it's encrypted on the way. One tap wipes everything either way.
Does Wumbi work offline, with no internet at all?
Yes, fully. Exchange rates are cached on the phone for 12 hours and every transaction stores the rate it was created with, so your history never shifts when rates change later.
Which currencies does Wumbi support?
64 currencies, plus Bitcoin, Ethereum and USDT down to 8 decimals. Every wallet keeps its own, you can type an amount in any of them, and your total converts to whichever one you want to think in.
How is Wumbi different from other budget apps?
You type free-form #tags as you go instead of maintaining a category tree, and a transaction saves with one tap. About three seconds, and the screen stays open for the next one. Then the tag map shows you which tags keep moving money together, which is the part a category list can never tell you.
When does Wumbi launch, and is it on iPhone and Android?
Wumbi is coming to both iPhone and Android. Join the early access list and you get one email on launch day, no newsletter, no spam.
Which languages does Wumbi support?
Seven: English, French, German, Dutch, Turkish, Russian and Arabic, with full right-to-left layout for Arabic.
Is Wumbi free?
Yes. Everything you need to track your budget is free and stays free, with no ads. There's a premium plan at launch for backups, bank sync, savings goals, widgets and deeper analytics, but the basics aren't behind it.
Can I use Wumbi without giving it my bank details?
That's the default. No bank connection, no Plaid, no card number, nothing to authorise. You type your own transactions in, which takes three seconds, and that's the whole mechanism. Bank sync exists in premium only for people who'd rather not type.
Is Wumbi better than a budget planner spreadsheet?
For daily logging, yes, because a spreadsheet needs you to be at a computer and Wumbi needs three seconds at the till. For annual planning a spreadsheet is still fine. Wumbi gives you the monthly and weekly breakdown a budget planner template gives you, with the charts already drawn.
