Caliperly is a unit converter designed with precise movement—every detail serves a purpose. THE DIFFERENCE Most converters are calculators with a unit dropdown. Caliperly is a precision instrument. The interface features visual caliper jaws that respond to your touch. Swipe to adjust values and watch the jaws move. It's tactile, intuitive, and unlike anything else on the App Store. FRACTIONS MODE Woodworkers, machinists, and makers: this is for you. Toggle between decimal (5.25) and fractional display (5 ¼). Enter measurements the way your tape measure reads them. Supports 1/16" precision. No more mental math. WIDGET-FIRST Convert without opening the app. Add Caliperly to your home screen or lock screen. Glance at your last conversion or tap to open directly to a specific category. The widget shows the same precision instrument aesthetic as the full app. 10 CATEGORIES - Length — inches, feet, meters, centimeters, millimeters, yards, miles, kilometers - Mass — pounds, ounces, kilograms, grams, stones, tons (US/UK/metric labeled) - Temperature — Fahrenheit, Celsius, Kelvin - Volume — gallons (US/UK labeled), liters, fluid ounces, cups, pints, quarts - Area — square feet, square meters, acres, hectares - Speed — mph, km/h, knots, m/s - Time — seconds, minutes, hours, days, weeks - Data — bytes, KB, MB, GB, TB (binary/decimal toggle) - Pressure — psi, bar, pascal, atmosphere - Energy — joules, calories, BTU, kilowatt-hours DESIGNED WITH INTENT No ads.

Verdict
The clearest difference is in-app purchases: Caliperly at none against Smart Tools's 1. Caliperly also leads on ads (none vs shown). Smart Tools's advantage is iOS requirement (11.0 vs 15.1). On price and device support there is nothing between them.
