Bill Runway: See Exactly What's Due Before Payday

You know the feeling: it's three days before payday, your account has $180 in it, and somewhere in the back of your mind you're pretty sure your car insurance autopays this week. Maybe. Or was that last week? You open your banking app, scroll through transactions, do the math in your head, and still aren't sure. Bill Runway was built to end that specific anxiety.

Open the app and you see a monthly calendar with every recurring bill marked on its due day. A bold headline at the top tells you the total amount and number of bills landing before your next paycheck. That's the whole idea, and it works exactly as well as it sounds.

The gap that bigger apps keep missing

When Mint shut down, millions of people went looking for something simpler, and most of what they found was either another full budgeting suite with a steep learning curve or a bare-bones reminder app that just pinged them on due dates. Neither one answered the question that actually matters: given when I get paid, what's hitting my account in the next few days?

Bill Runway focuses entirely on that window. You set your payday once, and the app draws a clear line between what's already gone this cycle and what's still coming before your next deposit. There's no account linking, no net-worth dashboard, no investment tracking. Just your bills and the calendar they live on.

The app ships with believable sample data already loaded, so you can poke around the calendar and try the flows without entering anything. When you're ready, swap in your real bills. It takes about two minutes.

How the runway view actually works

Tap any day on the calendar and the bills due that day slide into view below. Each card shows the bill name, the amount, the category (utilities, subscriptions, loans, and so on), and a small badge if autopay is on. That autopay flag is important: it's the difference between a bill you need to remember and one that will just happen, whether your account is ready or not.

The headline figure at the top updates as you add or edit bills. If your payday is the 1st and today is the 24th, the app totals every bill with a due date between now and the 31st and shows you that number front and center. You can adjust your payday at any time if it shifts, and the math recalculates immediately.

Try tapping the Add Bill button in the live demo on this page. Fill in a name, pick a due day, and set an amount. Watch the calendar dot appear and the runway total change. That's the whole interaction loop, and it's deliberately fast, because adding friction to a tool like this means people stop using it.

Who keeps this app on their home screen

The people who get the most out of Bill Runway are the ones juggling a predictable but tight monthly cycle: rent on the 1st, car payment on the 8th, electric and internet somewhere in the middle, and a cluster of smaller subscriptions scattered across the last two weeks. That's a dozen line items with a dozen different due dates, and keeping them in your head while also watching your account balance is genuinely hard.

It's also useful if you've recently moved out on your own and are figuring out your first real bill calendar, or if you've just taken on a new recurring expense (a gym membership, a new insurance policy) and want to see how it fits into your existing schedule before it surprises you.

The no-signup, no-bank-link design matters for this audience. A lot of people are reluctant to hand a third-party app access to their financial accounts, and they shouldn't have to. Bill Runway keeps everything local. Your bill list stays on your device.

A tool built from one clear idea

Bill Runway started as a single sentence: show me what's due before payday. That constraint is visible in every decision the app makes. There's no social sharing, no AI spending analysis, no premium tier with extra features. The calendar is the feature. The runway number is the feature.

The live version embedded here is the real app, running in your browser. Swipe between months, add a bill, change the due day, toggle autopay on and off. The seeded data gives you something to work with right away, but the point is to replace it with your own. Once you've spent five minutes entering your actual recurring bills, the runway view stops being a demo and starts being genuinely useful.

If you find yourself wishing it did one more thing, that's a reasonable next step. The same idea-to-app pipeline that produced Bill Runway can produce your variation of it, or something built around a completely different problem you're trying to solve.
