DipSwitch

Set a DMX address on a dip-switch block without doing binary in your head, in the dark, up a ladder.

Type the address, read the switches. DipSwitch draws the block the way it looks on the back of the fixture, so you can hold your phone next to the real thing and compare it switch for switch.

It has been doing this job since 2008.

ON THE FIXTURE
• Enter an address and see the switch pattern immediately
• The block is drawn to match real hardware, with the ON marking and channel weights
• Set the number of switches to match your fixture, from 1 to 16
• Swap and mirror for blocks that are printed the other way round

PLANNING A RIG
• Set the offset to your fixture's channel footprint and step the whole rig one button at a time
• See how many fixtures fit a 512-channel universe, and the last address you can use
• Save fixtures you use often as profiles, so the channel count is one tap away
• Know two addresses and need the rest? Enter both and the spacing does the work
• Tick off fixtures as you patch them, and share the finished list as a PDF

ON APPLE WATCH
• The whole calculator on your wrist, for when one hand is holding the fixture
• Tap the switch block and the Digital Crown sets the address — one click per offset
• A complication puts the current address on your watch face
• Address, offset and fixture profiles stay in sync with your iPhone

PRIVACY
No account, no tracking, no advertising identifiers. The app collects anonymous counts only — which tabs get used, how many switches — never an address, never a fixture name, never a device identifier. You can switch it off in About.
