Level Money (2013–2017)
Level Money is the one people still miss. You connected your bank, it worked out your income and your bills, and it showed you a single number it called Spendable: for today, this week, this month. Nothing to set up, nothing to maintain. You opened it for four seconds, saw whether brunch was fine, and got on with your day.
Capital One bought the company in 2015 and shut the app down in September 2017. Some of the thinking resurfaced in Capital One's own tools, but the app itself never came back. People are still asking for a replacement in forum threads years later, and for most of that time the honest answer was nothing.
Simple and Safe-to-Spend (2012–2021)
Simple went further than anyone, because it wasn't an app sitting on top of your bank. It was the bank. Safe-to-Spend took your actual balance and subtracted upcoming bills and your goals, right on the card you were paying with. The number wasn't an estimate in some companion app. It was your account telling you the truth.
That depth is also what killed it. BBVA bought Simple in 2014, then agreed to sell its US business to PNC, and Simple got wound down in the middle of that deal. In May 2021 the accounts were migrated to a standard checking product and the budgeting features just vanished. Safe-to-Spend didn't fail. It was collateral in a bank merger, and no bank since has rebuilt it properly.
Mint (2007–2024)
Mint was the biggest of the three and lived the longest, though it was a different philosophy: categories, trends, the whole dashboard. For millions of people it was the first thing that made their money legible at all, and it was free. The revenue came from referrals and ads. Intuit bought it in 2009.
Mint didn't die because users left. Intuit closed it in early 2024 and pointed everyone at Credit Karma, which doesn't do the budgeting Mint people actually relied on. You could have used Mint faithfully for fifteen years and it made no difference, because you were never the customer. Advertisers were.
The pattern: you weren't the customer
None of these products died of bad reviews or shrinking usage. In every case, the person using the app wasn't the person paying for it. Level was paid for by an acquirer. Safe-to-Spend was paid for by a bank's strategy. Mint was paid for by ad budgets. When the payer lost interest, the product went with it, and how much users loved it never entered the equation.
The apps that survived the decade all charge money: YNAB, Monarch, Copilot. That's probably the right lesson. When users pay, the incentives point at the users. But they're also all category-first budgeting suites, built for people who treat budgeting as an active practice. Assign categories, true up envelopes, read the reports. Plenty of people genuinely like that. The Level crowd never did. What they wanted was the opposite: do the work for me and hand me the number.
Why the one number is hard to keep alive
Part of it is that the one number is expensive to compute honestly. It has to know your real income rhythm, which bills are actually fixed, what you've already spent this month, what you're saving toward, and what a normal month's surprises tend to cost you. Then it has to stay right while all of that drifts. A category tracker can be a little wrong everywhere and still feel useful. A safe-to-spend number that's wrong is worse than no number at all, because you'll act on it.
So the idea kept getting built by teams who could afford to subsidize it, and it kept dying when whoever owned the subsidy changed direction. The idea never failed. The business models it lived on did.
Where the idea lives now
Bablo exists because of this history. It picks up where Level and Simple left off, with one safe-to-spend number and the full math a tap away, plus the parts they never got to build: a month-end forecast and a coach that catches drift early. It's subscription-funded, with no ads and no selling of data, so the person using the app is the person paying for it. If Level or Simple was your app, Bablo was built for you, and it's free while in beta.
Comparing the survivors first is a fair instinct too. There are head-to-heads with Copilot, Monarch, and YNAB.
