Calculators are boring. PopCalc isn't. Sculpted 3D numbers, keys that click back, and skins you'll actually want to look at.

Everything a calculator should do, done right, plus the parts that make you smile when you hit equals.
Every answer is a solid block of type that tilts with your phone and pops when you hit equals.
Decimal math, not floating point. 0.1 + 0.2 is 0.3, and 1 ÷ 3 × 3 is 1. Like it should be.
Tap any number or operator in your sum to change it. No clearing everything over one typo.
Trig in degrees or radians, powers, roots, logs, factorials and brackets. Turn the phone sideways for every key at once.
Length, weight, temperature, volume, area, speed, time, data, pressure and energy. Swipe to change units.
Three sound packs and tuned vibration for every key. Or switch them off, it's your calculator.
Three skins are free forever. Premium skins change the colours. Materials go further: each one has its own look, sound and feel, from soft Clay to clacky Mechanical.
Highlighted skins are free. The rest are one-time purchases, no subscription. Eight home-screen app icons are free too.


You can't buy it. The editor left a case file inside the app, five leads long. Crack them all and the skin is yours.
Yes. The calculator, scientific mode, unit converter, three skins and all app icons are free. Premium skins and materials are optional one-time purchases.
No ads, no account and no data collected. PopCalc works fully offline.
Not yet. PopCalc is Android only for now.
No. If you want it even lighter, Lite Effects Mode draws flat numerals with no 3D or tilt.
