Why We Decided to Build a Splitting App

BananaSplit started from a simple belief: shared money should feel fast, clear, flexible and human.

The best splitting app should not make a vacation feel like admin work.

But somehow, shared money still takes a lot of work.

I have been using splitting apps for a decade. Trips. Dinners. Rent. Subscriptions. Shared groceries. Random group plans. I split expenses several times a week, and after trying a lot of apps over the years, I kept running into the same problem: the experience never matched what I expected.

I want an expense sharing app that actually works for real life.

One that could handle:

  • Taking the work of adding expenses manually.
  • Settling debts with anyone, anywhere.
  • Spending metrics, totals, and exports when you need the grown-up stuff.
  • Web and mobile experiences that both feel good.
  • Dark mode for late-night trip accounting.
  • Subscriptions and recurring expenses, not just one-off dinners.
  • Expenses added from chat or natural language.
  • A product that feels fast, clear, and a little bit fun. 🍌

None of the apps do all of this.

Some had pieces. But even when the feature existed, the experience often felt like it was built around old rules. Too slow. Too stiff. Too much friction for something that should be simple.

So we decided to build our own

Even though it is a super crowded market, Leo and I decided to build the app we wanted for ourselves. That is when BananaSplit was born.

Over the last year, BananaSplit moved from an early TestFlight build to an official launch. Before launch, hundreds of people used the app, reported bugs, sent feedback, surfaced tiny annoyances and taught us a lot.

We made a bunch of improvements because of that loop. The "I wasn't expecting this" or "I really need that" comments made us move faster.

We officially launched a few weeks ago after a year of building, TestFlight feedback, and a lot of small improvements.

We do not have every feature yet. We're getting started, moving and listening.

But the direction is clear: shared money should be faster, clearer, more flexible, and much less awkward.
