## What is Caliper?

Caliper is a pocket precision toolbox — the measuring tools you reach for around the house, in one clean app.

FOUR INSTRUMENTS
• Bubble Level — 1-axis and surface. A real glycerin vial that turns true at 0.0°.
• Ruler — an on-screen scale in mm, cm, or inches.
• Angle Finder — a protractor and a tilt clinometer, with roof pitch and grade.
• Sound — a quick decibel check of the room.

GUIDED JOBS
Do not just read a number — get the job done. Hang a Picture, Level a Shelf, Roof Pitch, Level Furniture: each walks you through it and saves the result.

A MEASUREMENT LOG
Keep every reading and group them into projects — the kitchen shelf, the living-room frames.

PRECISION
Calibrate the level and ruler with a fine tilt offset, and feel a firm haptic tick the moment a reading is true.

HONEST BY DESIGN
No ads. No tracking. No accounts. Everything is measured on your device and stays there — Caliper collects no data.

The four instruments are free, and the log keeps your most recent 25 readings. Caliper Pro unlocks every guided Job, the unlimited log with projects, and precision calibration.

Note: readings depend on your device sensors and are intended for everyday use, not certified measurement.

Caliper Pro is an auto-renewing subscription, offered monthly or yearly with a 7-day free trial. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the current period ends; manage or cancel in Settings > Apple Account > Subscriptions.
