CALCSLATE LITE: FULL CALCULATION POWER. THREE PERSONAL SHEETS.
CalcSlate Lite includes the complete calculation engine without functional restrictions: every operation, variable, reference, annotation, precision setting, learning example and device experience is available.
The Lite edition limits only the number of personal saved sheets to three. Quick Sheet and read-only learning previews do not count. A one-time Full Version purchase removes this sheet limit — no subscription.
WHERE NUMBERS BECOME CONNECTIONS
CalcSlate is the calculator for calculation paths you can understand later. Build a calculation sheet line by line: enter values, link earlier results, reuse saved variables and label every step. The Calculation Rail keeps formula, explanation and result together.
CALCULATE WHAT YOU NEED
• Arithmetic, parentheses, percentages and modulo
• Powers, direct squares x², square roots and nth roots
• Reciprocal 1/x, absolute value, π and e
• sin, cos, tan plus asin, acos and atan — clearly in DEG or RAD
• ln, log₁₀ and exp
• Factorial, combinations nCr, permutations nPr, GCD and LCM
• Floor and ceiling
PRECISE AND CLEAR
Work with decimal values and choose your display precision. Where appropriate, fraction origins are retained internally while you see a clear result. Rounded values are visibly marked as approximations.
LINK AND EXPLAIN
Reuse results from earlier rows, save values as variables, and place names or annotations directly alongside the mathematics. Localized Quick Start and learning examples make it easy to begin. iPhone, iPad and Apple Watch can each calculate, save and edit; private iCloud sync keeps your sheets available across your devices when iCloud is enabled.
