How To Use Splync — Add Your Expenses

Let's Start Adding Your Expenses

Once you’ve created a new project, you can start adding expenses immediately. Each entry is automatically shared with your project members, and the project page updates in real time. There’s no manual syncing, no exporting, no sending screenshots. Everyone sees the exact same dates, categories, amounts, memos, and shared balance the moment a cost is recorded. Splync is built on a simple idea: “Split + Sync + Link.” When you enter something, it feels as if the entire project breathes with you. And, naturally, the same applies the other way around — you can also see your project members’ entries as soon as they add them. This sense of transparency is what makes collaborative budgeting surprisingly smooth.

Enter an Expense in Five Seconds

Splync aims to be the simplest budget-tracking app. Entering an expense should feel effortless — almost instantaneous. Unlike typical AI-powered budget trackers, Splync doesn’t require you to take photos of receipts. In fact, you can enter your expense faster than the time it takes for a receipt to print. Imagine this: you finish lunch at a cafeteria. The staff asks whether you need a receipt. You say yes. Ten seconds later, the cashier finishes printing, and the rolled receipt is handed to you. Then you point your phone at it, wait for autofocus, take the picture, and let the app “interpret” the numbers. All together, you’ve spent 15–30 seconds — and in exchange, the app may still extract inaccurate details. And a photo of your receipt, full of sensitive information, is now stored on your device and on a server somewhere. Splync takes a different approach. By the time the staff asks if you need a receipt, you’ve already tapped the category, entered the amount, and added a short memo — all within a few quick gestures. Many users say it becomes muscle memory after a week of use. You simply say “No” to the receipt and walk out, saving time, paper, and privacy.

No Worries About Expense Entries

Once you enter an expense, the details are visible only to your project members. And even if you notice a mistake afterward, there’s nothing to worry about — just tap the record and edit it. Fixing an entry is simpler than creating one. Even when adding a new expense, the payment date automatically starts as today’s date. In most cases, you won’t even have to touch it. If the expense was from another day, just tap the date and choose the correct one from the pop-up calendar. The memo field is optional, so most entries follow the same simple flow: pick a category with a clear icon, type the amount, and save. That’s it. Once you get used to it, you won’t even need five seconds. And you can edit your expenses whenever you need — unless the project has already been finalized and settled.

Expense Analysis and Settlement

You don’t have to wait for the project to be finalized to start reviewing your expenses. At any moment, you can see how much of your budget has been used in each category through clear numbers and bar graphs. Colored pie charts for category spending are available as well. With Splync, everything becomes transparent — who spent what, how much each person owes, how the balance shifts over time, and which categories tend to exceed their budgets. If needed, you can adjust category settings or update budget allocations during the project. All data updates instantly, and every member sees the exact same information in real time. When it’s time to settle up, the full analysis is always just one tap away. You can also export your project data, allowing you to review or analyze it in any format you prefer.

Trials and Errors Are Expected For Developers and Users

Think of each project as going through its own PDCA cycle — Plan, Do, Check, Act. A shared budget isn’t a one-time event. There’s always something to learn from how your group spends, saves, or balances costs together. That learning process is part of what makes Splync meaningful. As Splync grows, these tools will keep evolving — making analysis clearer and settlement even smoother. We’re improving the app step by step, and your feedback, ideas, and everyday use naturally become part of that process. In the meantime, we hope you enjoy sharing expenses and managing budgets with your project members, almost like a small collaborative game. It’s a cooperative experience where everyone wins together. Once you get used to the flow, it brings a surprising amount of joy to managing money as a team — a joy that comes not only from saving money, but from working together.
