BallCal -Balloon Calculator-

The calculator that keeps your answers on screen — that's BallCal. A regular calculator wipes the answer the moment it appears. BallCal is different. Every result stays on screen as a "balloon." Compare them, stack them up, reuse them as many times as you want. —— Sound familiar? —— "Wait, what was that number again?" — checking history over and over Mixing addition and multiplication in your head feels like too much You want to compare numbers, but a calculator only shows one at a time One typo, and you start the whole calculation over… BallCal solves all of it. —— Example: shopping —— "Spend $X to get a voucher… how do I combine items?" Line up your balloons, add and subtract, try every combo you want. Find the optimal way to clear the threshold. Background color is fully customizable. Match it to your fave's color job. Mood up. —— What BallCal can do —— Keep results on screen as "balloons" Like sticky notes on a whiteboard. Compare, total up, reference instantly — no need to open a history panel. Swipe a balloon down to reuse the number No more typing the same number twice. Pull it into your equation with one swipe. Add notes to balloons Tag them: "Person A's share," "transit fee," whatever. Even with lots of balloons on screen, you'll know what each one is. Lock frequent numbers Tax rate, base salary, unit price — pin numbers you use repeatedly. No more re-entering. Locks persist after you close the app, so you don't have to set them up again. Rewind to undo mistakes Built-in rewind. Misclicked? Snap right back to the previous state. Swipe digit keys to enter +−×÷ at the same time Once you get used to this, your input speed jumps. +×÷ swipe directions follow the standard iOS keyboard. Two-way copy/paste with other apps Equations with mixed full-width and half-width characters? Auto-converted on the fly. Even works with operators written as emoji or asterisks. Copy from Mail or messaging apps, paste straight in. Fine-grained settings Decimal precision, rounding, toggling features you don't need — tweak it to fit how you actually use a calculator. —— Where it shines —— Picking the optimal combo of fan goods Splitting tricky bar tabs Comparing "which one's the better deal?" while shopping Scaling recipes to a different number of people Converting to local currency while traveling Quick price simulations for estimates Trying combinations to fit a budget A simple register for flea markets and event stalls With a normal calculator, you end up nesting parentheses, mixing operators, and second-guessing whether the formula's even right. With BallCal, calculate in small chunks and pull them back in to keep going. No need to engineer a complex expression. Make your daily quick calculations faster and easier. Give BallCal a try. —— All this for free? Surely the paid stuff is expensive? —— Don't worry. You can use 2 balloons for free, with no limits. This alone is enough for everyday use.
