Remember When You Knew What Everything Did?
You know the feeling. You're three hours deep into a patch on your Eurorack (or Buchla, or Serge, or 5U rig), riding that creative flow, when you can't remember if that switch toggles the quantizer or unlocks some hidden LFO mode you discovered last month at 2 AM.
Or worse, you finally saved up for that complex module everyone raves about. The manual is 87 pages of dense tables. There's a switch upper left. And three knobs. A mysterious LED that blinks in morse code. You patch something, it sounds incredible... then forget how you got there.
RackDocs was born from exactly these moments. Built by someone staring at their rack, trying to remember what switch position enables through-zero FM.
YOUR RACK, ACTUALLY DOCUMENTED
Forget dusty manuals and half-remembered forum posts. Take a photo of your module, mark it up with everything you discover, build your own personal wiki. Every hidden feature. Every switch position. Every "wait, what does this input do when you mult it?" moment.
Documentation on your terms. As weird and specific as your patches.
Works with Eurorack, 1U, 5U/MU, Serge, Buchla, and more. Your format doesn't matter.
BUILT FOR EXPLORATION
• Photo-based—faceplates are already the perfect reference
• Smart image editing (crop that cluttered desk out)
• Import specs from ModularGrid (why type HP and mA manually?)
• Multi-format support (3U, 1U, 5U, Serge, Buchla—we don't discriminate)
• Annotation tools that make sense
DOCUMENT EVERYTHING YOU DISCOVER
• 12 annotation types for every control (not just "knob goes brr")
• Multi-context documentation (Normal Mode vs. Secret Alt Firmware Mode)
• LED behavior tracking (solid/blinking/pulsing/existential crisis)
• Switch position guides (up = quantized, down = chaos, center = ???)
• Multi-step operation notes (tap this while holding that)
• Copy/paste annotations
COMMUNITY LIBRARY
• Many modules documented by fellow patch nerds
• Share your discoveries
• Vote on documentation (yay or meh)
• Verified accounts prevent random chaos
SYNC EVERYWHERE, WORK OFFLINE
• iCloud sync across iPhone, iPad, and Mac (patching happens everywhere)
• Full offline mode (studio has no WiFi anyway)
• Your data stays yours (unless you decide different)
ORGANIZE THE BEAUTIFUL CHAOS
• Search by name, manufacturer, or custom tags
• Sort however your brain works
• Export cheat sheets as PDFs or images (print them, share them, flex on Instagram)
PRICING
Start free with 5 modules, 5 community downloads and 5 exports. Try it, see if it fits your workflow.
If you like it:
• Monthly - No commitment. Cancel anytime.
• Yearly - Best value. Less than a patch cable.
• Yearly Supporter - Locks your price forever. New features, same rate. For people who hate price increases and want to accelerate the development. Supporter badge!
• Lifetime - Pay once, own forever. No subscriptions, no renewals. Support indie development, not investors.
Why subscriptions? Servers cost money. Development costs time. This keeps the lights on and lets me build what you need.
WHO MADE THIS?
A modular enthusiast tired of scribbling notes at 3 AM. Someone who's bought complex modules, discovered secrets over weeks, then forgot everything after a creative break.
Not some corporation's idea of what modular users need. One of us built this because the struggle was real.
PERFECT FOR:
• Beginners drowning in manuals and tutorials
• Live performers needing instant reference (no PDFs on stage)
• Collectors managing systems too big to memorize
• Gear heads who RTFM and want to share knowledge
• Anyone who's thought "this module did something cool last week"
Download RackDocs. Document your discoveries. Patch with confidence.
Your rack is unique. Your documentation should be too.

- Added unsaved changes warning when exiting edit mode to prevent accidental loss of annotation modifications.
- Added local edit tracking for community-downloaded modules to enable safer update workflow and later prevent accidental data loss. This is not tracking edits you did before this app version. Please make a small edit to modules you want to mark as changed.
- Some old code prevented that you delete the last context of a module. This is now possible again.
- Combinations can now be rearranged in the "manage" list. No more random order by time of creation.
- Added a "Rate RackDocs" link in the "Help & Support" section of the settings. Would be happy if you people use it to drop some nice comments and good ratings. This can really make the difference for a solo developer like me. Thank you!
