Description

We built Rook Calculator because we were tired of RPN apps that looked like they were designed in the '90s.

If you've spent years with a quality scientific calculator, you know the feeling—the certainty of watching data move through the stack, the rhythm of a workflow you've internalized. Rook Calculator brings that RPN calculator experience to Android without the dated interface.

A STACK YOU CAN SEE WORKING
Most calculator apps treat the stack as an afterthought. Rook Calculator makes it the centerpiece. Watch your data push, pop, and roll with smooth animations that give you visual confirmation of every operation. It's not just eye candy—it's feedback that keeps you confident.

BUILT FOR THE FIELD
Surveyors, engineers, scientists—if your work demands precision, this RPN calculator delivers.
• Scientific Toolkit: Trigonometry, logs, powers, roots, and hyperbolic functions.
• Angle Modes: Degrees, radians, and gradians supported.
• Equation Solver: Quickly handle repetitive variable solving.

YOUR WORKSPACE, VISIBLE
No more guessing what's stored where.
• 26 Registers: Store variables in A–Z.
• Memory Viewer: See your entire workspace at a glance.
• Real-World Tools: Fractions, unit conversions, and full statistical analysis (linear regression, mean, std dev).

MULTIPLE LAYOUTS
Whether you prefer the classic 35s-style layout or a simplified scientific view, Rook Calculator adapts to your workflow. Switch layouts anytime without losing your stack or stored data.

MODERN ANDROID, CLASSIC PRINCIPLES
Material 3 design. Clean typography. Smooth animations. Rook Calculator feels like it belongs on your device—not like a '90s emulator skin stretched to fit your screen.

RESPECTS YOUR TIME & PRIVACY
• Zero Ads.
• Zero Tracking.
• Zero In-App Purchases.
• Offline-First.
• Buy it once, own it forever.

Try it risk-free. Google Play offers a 2-hour refund window. If the stack logic doesn't feel right, one tap gets your money back.

Great calculator to have in the field or office. Not bogged down by stupid UI and has a great "help" section to get used to the different tools
