Arctic Calculator (Science)

Touch any number: move it, change an old calculation, hold the answer to see the work. Solves, graphs and teaches. No account, no ads, no internet.

Scientific calculator, equation solver and graphing tool for iPhone and iPad. Touch any number: move it, change an old calculation, or hold the answer to see how it was worked out. No account, no ads, no subscription, no tracking. It works without internet.

CALC

• Hold a number and drag it: the answer follows, and is calculated for real when you let go
• A paper tape of your latest calculations: change an old one and the rows that carry on from it are recalculated
• Hold the answer for the work step by step, other forms (fraction, percent, hexadecimal) and how it was checked
• Type in words: "20% off 480", "5 km to mi", "15% tip on 845 split 4"
• Swipe the answer up to see 20, 40 or 60 checked digits

SOLVE

• Type the problem and the app figures out what kind it is
• Equations, inequalities, systems, derivatives, integrals and limits, step by step
• Steps in two levels, Simple or Advanced
• Every answer says how it was checked, and many come with a drawing

MORE IN SOLVE

• Probability, statistics, finance, chemistry, units and bits
• Complex numbers, matrices, vectors and differential equations
• Series, number theory and geometry

GRAPH

• 2D and 3D graphs: pan, zoom and rotate with your fingers
• Your graph saves itself; points, your own functions and derivatives
• Trace, Tangent and Table one tap away, with undo and redo
• Roots, maxima, minima and intersections with more digits
• 3D surfaces that move live with the sliders
• Jumps and asymptotes are drawn as breaks, with no fake lines

DATA

• Paste data from a spreadsheet and get a summary right away
• Mean, median, standard deviation, regression and confidence intervals
• A short explanation of what your results mean

LEARN AND LIB

• A question a day, practice that follows your mistakes and a daily goal you can see
• Formulas for algebra, geometry, physics, chemistry and more, sent to CALC, GRAPH or SOLVE with one tap

GEOMETRY

• Points, lines and circles you can move, with exact measures

MADE FOR YOUR SCREEN

• On iPad it uses the space with several panes at once
• Landscape layouts, and it respects the Dynamic Island
• Larger Text, VoiceOver, dark mode and five accent colors
• Runs well on phones that are a few years old

WIDGETS, SHORTCUTS AND SIRI

• Six widgets, including a calculator you can use from the Home Screen
• "Calculate in Arctic" with Siri and Shortcuts

IN YOUR LANGUAGE

• English and Spanish, following your device language
• Numbers in your region's format: 1,234.5, 1.234,5 or 1 234,5
