DreamCalc — Calculator

DreamCalc is a precise calculator with scientific functions (sin, cos, tan, log, ln, √, x², n!, π, e), percent and calculation history. No account, no subscription. EXACT ARITHMETIC 0.1 + 0.2 = 0.3, not 0.30000000000000004. 1 ÷ 3 × 3 = 1. Large whole numbers keep every digit. Percent works like a shop calculator: 200 + 10% = 220. SEE THE ANSWER WHILE YOU TYPE The result appears under the expression before you press “=”. Press it, and the answer grows into place. Operators are highlighted, parentheses close themselves, and a second operator simply replaces the first. SCIENTIFIC WHEN YOU NEED IT One arrow opens sin, cos, tan and their inverses, ln, log, eˣ, 10ˣ, √, x², powers, factorial, π and e — in degrees or radians. Turn the phone sideways and every function sits right next to the keypad. HISTORY Every calculation is saved by day. Tap one to bring its result back. The history stays on your phone. LITTLE THINGS • long-press the display to copy or paste a number • long-press ⌫ to clear everything • your expression survives a restart • the decimal comma or point and digit grouping follow your phone’s language • key vibration that you can turn off DESIGN Pure black with orange accents: dimensional graphite keys, a glowing equals key, and a black that simply switches pixels off on AMOLED screens. PRIVACY Everything is calculated on the phone itself, and your history stays there too. Available in 30 languages. Part of the Dream Apps family.
