About this app

Prime Kit turns your phone into a precision toolbox — instruments with the feel of real workshop hardware, and more on the way.

LEVEL — A machined bullseye level plus edge and plumb vials. Calibrate against any surface, get live angles and slope, and hear a soft chime the moment you hit level. On iPad, landscape mode shows all three vials at once, workbench style.

ANGLE — A rotating protractor. Align your phone's edge with one line, tap Start, rotate to the second line — the swept angle reads out live, clockwise or counterclockwise, powered by the gyroscope for magnet-proof accuracy.

COMPASS — A weighted dial with true-north headings, live accuracy grading, and built-in calibration guidance when the magnetic environment misbehaves.

RULER — Measure small objects directly against your screen with draggable markers, in centimeters or inches, from either edge and in either direction.

LOCATE — Your position at a glance: GPS coordinates, altitude, speed, and signal quality, plus your country and nearest city. Great for hikes, road trips, or just knowing exactly where you stand.

No account. No sign-up. Sensor data never leaves your device — location is shown to you and never stored or shared. A single small ad banner keeps it free.
