PatchMap is the fast, structured way for Eurorack players to document, search, and recreate their patches. Stop relying on blurry phone photos and scattered notes — capture every connection in seconds and find any patch later. Fast Patch Recording Pick a module, mark an output and an input, and save the connection. Logging a full patch takes seconds, not minutes, so you can document a great sound before it slips away. Your Module Library Build a library of your rack's modules once and reuse it for every patch. Add modules with their HP, type, and I/O so your records stay accurate and consistent. Powerful Search Search your entire patch history by module name, tag, or date. The good patch you made last month is always one tap away. Signal Flow Visualization See each patch as a clean connection diagram — modules laid out with color-coded cables — so you can understand the routing at a glance and recreate it exactly. Tags & Notes Organize patches with tags like ambient, percussion, or drone, and add text notes to capture settings, knob positions, and ideas. Shareable Patch Cards Generate a clean patch card image and share it to Instagram, Reddit, or with friends in one tap. Privacy First PatchMap works completely offline. No account, no cloud, no data collection. Everything stays on your device. Built for modular synth players with mid-to-large systems who patch often and want to remember every great sound.

Coil is a spring reverb built from the ground up around the thing that makes real spring tanks so good: they're physical. The springs stretch, resonate, build up energy, and get hit, and when you kick the tank, you hear it. There are no impulse responses inside Coil. The springs themselves are simulated while you play. Change the physics and you change the sound. TWO TANKS, TWO PERSONALITIES • LONG — big, slow, heavy springs. More depth, more wobble, more of that surf-era drip. • SHORT — tighter springs with a brighter, immediate response. Less wash, more snap. KRAANG! Hit the pedal and the springs respond with a burst of metallic chaos. Because they're physically simulated, what comes back depends on where the springs are in their motion when you land. Try it while the reverb is already ringing. It's ridiculous. It's also extremely useful. THREE KNOBS, NO MYSTERY • MIX — how much spring you want. • TONE — how fast the top end dies in the steel. Not an EQ: you're changing the behaviour of the spring itself. • DWELL — how long the springs keep moving. AND THE JEWEL Tap it and the whole thing goes through a measured amp stage — presence, grit and all. Nobody will tell you this is there. WORKS EVERYWHERE • AUv3 for GarageBand, Logic Pro, AUM and any Audio Unit host • Standalone app — plug in and play, no DAW needed • MIDI learn on every control • One purchase: Mac, iPad and iPhone No giant metal tank. No springs to break. No road case. A spring you don't have to haul around.

Verdict

The call

The clearest difference is price: PatchMap at Free against Coil's $0.99. Coil's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 17.0). On ads and in-app purchases there is nothing between them.
