Hey PH! I'm Rupesh, a solo dev from India. I built CalcBook because I kept losing track of freelance invoices in my notes app. It's fully offline, free to try, and I'd love your honest feedback. What calculation would you test first?

CalcBook is a natural language calculator for Android. Type like you think: coffee $4.50 + muffin $3.00 → $7.50. Works fully offline.
Freelancers, travelers, students: stop switching between Notes and Calculator. CalcBook merges them.
