Themed calculator and widget
$2.99
Six complete design systems, from dot-matrix to phosphor terminal to warm walnut. Plus a Home Screen widget whose keys actually work. No subscription, no ads. Pay once.
A calculator worth looking at.
Six complete design systems ship in the app. Pick one and every screen wears it — keys, type, spacing and finish, all redrawn.
NULL
Dot-matrix numerals on graph paper, one red accent.
ROOK
A phosphor terminal. Scanlines, screen glow, and eleven screens to pick from: Nostromo green, amber monochrome, cryo-bay teal, paper white and more.
LUMEN
Frosted glass, ten accent colors.
PANEL
Machined hardware around an inset display.
MIN
Flat and quiet. It gets out of the way.
RETRO
Cream keycaps on walnut, straight out of the seventies.
A REAL CALCULATOR
Type the whole line — 25% x 975 x 8 — and it solves it with proper precedence and parentheses, instead of running a total as you go. The math uses exact decimals, so 0.1 + 0.2 is 0.3, not 0.30000000000000004. Every result goes on a tape that keeps your last two hundred. Tap any line to bring it back.
SIX CALCULATORS IN ONE
Basic. Scientific, with trig, logs, powers, roots, factorials, degrees or radians. A converter for length, weight, temperature, volume, area, speed, data and time. Tip and split. Percentages. Days between dates.
A WIDGET THAT ACTUALLY WORKS
The large Home Screen widget is the full pad — all twenty keys. Medium has eighteen. Small shows your last result. Every key computes right there on the Home Screen; the app never opens. Long-press to choose which theme it wears.
BUILT FOR IPAD TOO
Not a stretched-up phone app. The iPad layout is its own, in both orientations, and one purchase covers both devices.
NOTHING LEAVES YOUR DEVICE
Coast Calc makes no network connections at all. No account, no analytics, no ads, no subscription. Your calculations, history and settings stay where you made them.
Pay once. Keep it.
