Hey Product Hunt! 👋

I built the Expense Matrix Splitter because I was frustrated with how most expense apps fragment the data. You usually have to click through multiple screens just to see who owes what, losing the "big picture" in the process.

I wanted everything centralized in one structured, powerful table. While 'simple' apps are great for a coffee run, they often fail when things get complicated, like needing a precise percentage split for one bill, but a fixed dollar-amount split for the next. This app handles those edge cases with ease while keeping the workflow intuitive.

I’m also a big believer in the Local-First movement. Most tools demand your email and your data before you can even begin. This tool wants neither.

Key features include:

Advanced Matrix Logic: Visualize every person and every expense for the whole trip on one screen.

Custom Split Logic: Total control with exact $ or % splits per person.

File-Based Saves: Export your plan as a .json file and reload it whenever you want. No servers, no accounts, 100% privacy.

I’d love your feedback—specifically on the Matrix UI. Does this layout make sense for your workflow? If you find any bugs, let me know and I’ll get them into the lab for a fix!

Happy inventing, Manic Inventor
