Built for financial accuracy,
designed for harmony.
Every feature in SplitNest is engineered to eliminate ambiguity and resentment in shared living arrangements.
1. Expense Tracking & Lifecycle
Record household expenses with detailed descriptions, split participants, and currency values. Expenses support full non-destructive voiding and replacement correction links, maintaining a complete, auditable ledger without altering historical settled records.
2. Equal & Exact Splitting
Choose between splitting evenly across all housemates or specifying exact rupee minor units for each member. Server-side validation guarantees that individual split shares sum to 100% of the total expense amount.
3. Communal Kitty (Shared Fund)
Housemates can contribute upfront to a collective household pool. When communal supplies like milk, cleaning products, or cooking oil are purchased, they are debited directly from the Kitty, eliminating the need to create micro-expenses between individuals.
4. Who-Owes-Who Debt Simplification
Our greedy two-pointer algorithm minimizes the total number of peer-to-peer money transfers required to settle the house. It collapses multi-hop obligations into direct, net transfers so you only pay what you truly owe.
5. Peer Settlements
Record direct repayments between housemates. Recording a settlement updates outstanding balances in real-time, closes debt obligations, and logs an immutable record in the household activity audit trail.
6. Nest Membership & Rosters
Create distinct Nests for different living spaces. Invite housemates using secure 10-character invitation codes. Enforce departure invariants: members cannot leave or be removed if they carry an outstanding balance.
7. Activity Audit Timeline
An immutable chronological activity feed recording who created an expense, who paid whom, who joined the flat, and when expenses were voided or corrected. Full transparency eliminates disputes.
8. Secure Authentication & Cross-Platform
Argon2id password hashing, native Google Sign-In on Android, and Google Identity Services for web. Stateless JWT access tokens paired with HttpOnly refresh cookies on web and Android Keystore on mobile.
Push Notifications
Native device alerts when a flatmate adds an expense, records a settlement, or invites you to a new space (M16).
Receipt Scanning & OCR
Automatic line-item parsing from supermarket receipts and utility bills using local machine intelligence.
Direct UPI Integration
Deep-linked UPI app intent triggers for instant one-tap settlement between Indian bank accounts.
