CalcSpace

Give every calculation a place - and keep the useful ones connected. CalcSpace turns your iPhone or iPad into a personal workspace for numbers. Compare everyday choices, explore a graph, keep project calculations together, or take a quick math-puzzle break without losing your work. BUILD YOUR OWN WORKSPACE Put 1-4 different calculators on one screen and organize up to 8 saved tabs. Mix a scientific calculator with a graph, compare two shopping options, or keep a converter beside your running total. Search the tool picker, choose Math, Everyday, or Fun, and name tabs for your projects. NEED MORE ROOM? PINCH TO EXPAND Spread two fingers on a calculator to fill the workspace with that panel. Pinch closed to return to the same grid with your calculation intact. Responsive text, larger mathematical symbols, and a tactile keypad make work easier to follow at different panel sizes. LET RESULTS WORK TOGETHER Basic and Scientific show live results as you type. Revisit calculation history, edit expressions with the keyboard, and save useful results as named variables. Reuse those values in Basic, Scientific, Graph, and Calculus; the Variables tool lets you manage them in one place. EXPLORE MORE THAN AN ANSWER Graph explicit, polar, parametric, and implicit relationships, including inequalities. Explore parameters with sliders and animation, inspect points of interest and function tables, and share graph images or table CSVs. Matrix, Statistics, numerical Calculus, and Probability tools make room for deeper questions. 26 TOOLS, ONE PLACE Math: Basic, Scientific, Graph, Matrix, Statistics, Calculus, Variables, and Probability. Everyday: Tip, Running Total, Unit Converter, Currency, Discount, Age & Date, Unit Price, Recipe Scaler, Hourly/Salary, and Cost Per Use. Fun: Dog / Cat Age, Life in Numbers, Life in Weeks, Pizza Value, Birthday Countdown, Decision Picker, How Long Will It Take?, and Lottery Reality Check. MAKE EVERYDAY MATH PERSONAL Compare pizza sizes by value. See how repeated use changes the cost of something you bought. Turn progress toward a goal into an estimated completion date. Explore birthday countdowns and life milestones. Lottery Reality Check explains probabilities; it does not sell tickets, offer prizes, or predict winning numbers. Optional, clearly marked Chaos Mode adds playful variation only to Fun calculators and is off by default. A LITTLE SOMETHING FOR YOUR BRAIN Visit Play for a daily math challenge with hints and an explained solution. In Make the Number, use all four number tiles exactly once to reach a target. Discover 25 local achievements as you explore, and return to your saved workspace when you are ready. MAKE IT YOURS Choose color skins, system/light/dark appearance, high contrast, and reduced motion. VoiceOver labels and accessible alternatives support navigation.
