Formulary+ vs NewtonDesk

Formulary+ is not another formula list. It is a complete computational reference — 4,727 formulas across 16 disciplines, each with an interactive solver, evaluator, or worked example that lets you compute, verify, and learn, not just look things up. Every equation is rendered in real-time LaTeX (KaTeX), not screenshots. Every variable is defined with its SI unit. And every formula you open is one you can actually use. WHAT MAKES IT DIFFERENT Interactive Solver — Pick any variable, enter the rest, get the answer with full step-by-step solution. Covers 1,500+ formulas across all 16 disciplines. Evaluator — For identities, bounds, and series: plug in numbers and see both sides computed side by side. You see not just that a claim holds, but by how much. Worked Examples — For complex equations (tensors, PDEs, procedures): a real computation with real numbers, showing every substitution step. Personal Notes — Write directly on any formula. Export all notes as Markdown — your work is never locked in. 4,727 FORMULAS · 16 DISCIPLINES · 150 SUBCATEGORIES Mathematics — 356 formulas Algebra · Calculus · Linear Algebra · Differential Equations · Statistics & Probability · Number Theory · Discrete Math Physics — 448 formulas Classical Mechanics · Thermodynamics · Electromagnetism · Optics · Waves · Quantum Mechanics · Relativity · Fluid Mechanics Chemistry — 241 formulas Stoichiometry · Thermochemistry · Kinetics · Equilibrium · Electrochemistry · Quantum Chemistry Geometry — 229 formulas Euclidean · Analytic · Differential · Topology Mechanical Engineering — 342 formulas Computer Science — 355 formulas Electrical Engineering — 319 formulas Civil Engineering — 343 formulas Biology & Biomedical — 203 formulas Environmental Engineering — 311 formulas Geological Engineering — 271 formulas Geochemistry — 204 formulas Geophysics — 215 formulas Chemical Engineering — 325 formulas Meteorology & Atmospheric Science — 296 formulas Astronomy & Astrophysics — 269 formulas BUILT FOR REAL WORK Real LaTeX rendering — KaTeX, not static images Full variable definitions with SI units Smart search across 4,727 entries Favorites — build your personal formula collection Related formulas — discover connected equations Share as LaTeX, plain text, or rendered image Export notes as Markdown Backup & restore your favorites and notes Dark mode · All iPhone & iPad sizes FREE TO TRY, FAIR TO BUY Browse the entire catalog for free — every category, every search result, every title.
