Financial features built for human coexistence
Equal & Exact Splitting
Split evenly across everyone, or assign precise rupee amounts to specific individuals. Every calculation is verified down to the exact minor unit so totals always match.
Communal Kitty
Maintain a dedicated shared reserve fund for household staples like cooking gas, cleaning supplies, and groceries without tracking every tiny individual purchase.
Debt Simplification
Our greedy two-pointer debt simplifier eliminates circular debts. If Alice owes Bob ₹500 and Bob owes Charlie ₹500, Alice simply pays Charlie directly.
Immutable Corrections
Mistakes happen. SplitNest voids incorrect records non-destructively and creates clean audit-linked replacement expenses, maintaining a pristine accounting ledger.
Settlement Invariants
Housemates cannot leave or be removed from a Nest if they have an unsettled balance. Clean mathematical closure ensures nobody is left shortchanged.
Zero Floating Point Math
Financial state is maintained as 64-bit integer minor units (BIGINT). Never lose or gain a fractional paisa to JavaScript rounding bugs.
Unified Cross-Platform Engine
One account. Native Android and desktop web.
Register once and log in anywhere. Your financial state, balances, and household history live on the single authoritative Spring Boot backend and PostgreSQL engine.
