Caliperly
Utilities
Free · Designed for iPad
The unit converter that feels like a precision instrument. Swipe the caliper jaws to adjust. Native fractions for workshops. Widget-first design.
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.

DESIGNED WITH INTENT
No ads. No clutter. No generic calculator aesthetic. Caliperly draws inspiration from precision instruments—the kind you'd find in a watchmaker's workshop. Brushed metal textures, jewel-red accents, and typography that feels engraved, not printed.
