The Problem
Writing checks in the Philippines requires precise formatting — converting amounts to words in Pesos and Centavos, managing payee details, and avoiding costly errors. Many existing tools are desktop-only or not tailored to Philippine banking standards.
The Solution
Philippine Check Writer is an Android app that streamlines check preparation for individuals and businesses. It automatically converts numbers to words, saves payee details locally, and formats every field to Philippine banking conventions.
Key Features
- Automatic number-to-words conversion (Pesos and Centavos)
- Payee management with search for faster check preparation
- Drafts, bounced check calculator, and report generation
- Print scale control and font selection
- All data stored locally on-device for privacy
Lessons Learned
Building a finance tool for Philippine users meant prioritizing offline reliability and zero data collection. Cross-platform development with Expo and React Native let me ship quickly while keeping the interface consistent across devices.
