01

Product / System Purpose

Flow reimagines personal finance by replacing tedious spreadsheets with a real-time fluid pool simulation. As expenses are logged, dynamic liquid levels drop with responsive particle waves. Its mathematical projection engine forecasts liquidity 60 days in advance to prevent shortfalls.

02

Problem Being Solved

Rendering 60 FPS real-time fluid dynamics on low-power mobile GPUs without battery drain while safeguarding all transaction data locally with biometric and encrypted secure-enclave storage.

03

Engineering Approach

Engineered custom trigonometric wave algorithms utilizing SwiftUI Canvas API. Encrypted local storage with SQLCipher and integrated a Decoy PIN security vault that renders dummy balances under duress.

Technical Modules

Liquid Pool Visualization

Interactive fluid interface with responsive particle waves reflecting real-time income and expense ratio.

60-Day Predictive Sandbox

Algorithmic forecasting sandbox mapping recurring subscriptions and anticipated revenue to predict future runway.

Biometrics & Decoy-PIN Vault

Face ID/Touch ID gating paired with a secondary decoy PIN vault displaying isolated dummy balances.
