Pin Head is a simple but powerful tool to calculate the pinning of a cylinder.

Calculate 2, 3, or 4 keys at a time with pin lengths of 4, 5, 6, or 7.

Easy to use interface: Every text field "autotabs" so there is no need to tap on every box.

All master pins are displayed just as a cylinder would be pinned.

Picking calculator measures the difficulty from a range of zero (easiest) to ten (hardest) on every chart created.

System selector provides the appropriate driver/top pins, checks for any MACS and pin violations by highlighting the offending cuts, grants ability to convert bittings into pin sizes for 3-thousandths and 5-thousandths pin kits, and calibrates the picking calculator.

Ability to change the value of zero to equal 10 when not utilizing a system (automatically selects the appropriate value for each system).

Landscape mode for a larger readout.

Most popular pinning charts are readily available, providing both bottom and top pin sizes as well as key depths.

Compatibility: iPhone / iPod touch on iOS 8.0 or later and iPad on iOS 12.0 or later.
