Features
GetCalcMaster is built like a workstation: quick tools, consistent history, and a notebook that keeps everything connected.
Notebook-first workflow
Work in cells. Keep context. Re-run safely. Save locally.
Use text cells for derivations and math cells for evaluation. Keep your reasoning next to results.
Clean results with optional explanations where available — ideal for learning and review.
From calculators, graphs, conversions, and currency: capture what matters, then continue in the notebook.
Calculator modes (consistent UI)
Each mode shares the same core and history model, so you can switch without losing flow.
Fast input, clear results, and notebook export.
Angle modes and a workflow built for speed.
Conjugate, magnitude, phase, cis, and more.
Binary/hex/dec operations with clean formatting.
Work in realistic ranges and keep results consistent.
Open a starting notebook and iterate.
2D & 3D graphing
Visualize quickly, then push key points or equations into the notebook.
Unit conversion
Convert quickly and keep an audit trail (inputs + outputs) in history for later review.
Currency tools
Convert currency values and keep your calculation steps in one place.
Offline-first PWA
Install it. Use it on flights. Keep working even when the network disappears.
Data persists on-device (IndexedDB with safe fallback).
Core assets cache for quick startup and resilience.
Clean separation of markup and scripts.
Add-ons (specialized toolkits)
Expand GetCalcMaster without clutter: add domain calculators as modules. Finance tools are educational estimates — always verify.
Country + year selector, bracket breakdowns, notebook export.
Amortization, extra payments, PMI/escrow, ARM scenarios, CSV export.
Keep the workstation lean by moving niche tools into add-ons.
Templates and shared defaults (optional roadmap).
Developers: evaluation API
The compute core is exposed as a stable JSON API, ideal for automations or embedding.
