## What is Penalgo?

Penalgo is a powerful formula calculator designed to simplify recurring calculations.
Instead of entering the same formula again and again, you define it once and reuse it anytime.
Create your own custom formulas using two flexible inputs (X and Y), rename fields, and adapt the calculator to your exact workflow — whether for daily calculations, productivity, planning, or personal projects.
Key Features
• Create and reuse custom formula with X and Y
• Save results automatically in a clear history
• Rename input fields and customize labels
• Fully offline usage – no account required
• Fast and minimal interface focused on efficiency
Penalgo also includes two integrated timers that help you track time-based values and processes directly inside your calculation workflow.
Designed for Repeated Calculations
Penalgo is built for anyone who regularly performs the same calculations and wants a faster, more flexible alternative to standard calculator apps.
Use it for:
• Personal calculations
• Productivity workflows
• Study and learning
• Work-related formulas
• Everyday problem solving
Widgets & Notifications (Premium)
