Solve any right triangle in seconds — no formulas, no calculator gymnastics. Right Triangle Calculator does the trigonometry for you. Enter any two values — two sides, a side and an angle — and it instantly computes everything else: the missing sides, both angles, and the hypotenuse. It's built for people who measure in the real world, so you can type the way you actually work: feet and inches, fractions, or metric. Whether you're framing a wall, cutting a rafter, laying out stairs, building a deck, or checking homework, the answer is one tap away. REAL-WORLD MEASUREMENTS • Mix feet, inches, and fractions — type "5 ft 3/8 in" directly • Work in metric too — meters and centimeters • Set fraction precision from whole numbers down to 1/64" • Control decimal places for clean, readable results SMART TRIANGLE SOLVER • Enter any 2 of 5 values (sides a, b, c or angles A, B) • Side c is always the hypotenuse, angle C is locked at 90° • Automatic conflict handling — change your mind and it keeps up • Powered by the Pythagorean theorem and trig, done instantly SEE IT, DON'T JUST SOLVE IT • Live diagram redraws as you type • Rotate the triangle to match your layout • Clean, labeled sides and angles you can actually read ARC & CHORD MODE • Switch to curves to solve chord, arc length, and segment height • Perfect for woodworking, masonry, and curved layouts MADE YOUR WAY • Choose label color, label size, and decimal precision • Optional tap sounds • Fast, offline, and distraction-free PERFECT FOR Carpenters • framers • woodworkers • DIY builders • roofers • machinists • students • teachers • engineers • anyone who needs a fast right-angle answer. Just measure, tap, and build.

Verdict
The clearest difference is in-app purchases: Right Calculator at none against Triangle Calculator's 2. Right Calculator also leads on update cadence (every 6 days vs every 4 months). Triangle Calculator's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
