The Ultimate Reference for Guitar Technicians and DIY Builders. Whether you’re upgrading a boutique humbucker or repairing a vintage classic, CoilSense eliminates the frustration of "mystery wires." Built by a professional guitar technician with over 15 years of experience, this is the most comprehensive pickup wiring resource on the App Store. BROWSE A MASSIVE DATABASE Stop searching forums for blurry diagrams. Access a curated, searchable library of 80+ manufacturers, from global giants to boutique builders. Detailed Specs: View wiring codes, coil polarity, and wind direction for every pickup. Multi-Format Support: Covers 4-core humbuckers, single-coil shielded wires, and multi-voice active systems. Live Updates: New manufacturers are added via Firestore—no app update required. PRO-GRADE WIRING LOGIC Most diagrams assume one type of component. CoilSense adapts to your actual hardware. Alpha vs. CTS: Instantly switch between the two most common pot types. They are wired differently—CoilSense shows you exactly how. Advanced Switching: Visualize complex layouts for Coil-Splitting (Inner/Outer coil), Phase Switching, and Series/Parallel configurations. Side-By-Side Compare Mode (Pro) The industry’s first "Visual Translator" for guitar pickups. Upgrading from one brand to another? Moving a build from a budget guitar to a premium one? Compare Mode allows you to put two different manufacturers or component types side-by-side to see exactly how the wiring changes. Real-Time Translation: Compare a Seymour Duncan to a Bare Knuckle instantly. No more cross-referencing static charts or manual note-taking. The "Link" Feature: Keep your settings in sync. Change the wiring to "Series/Parallel" on one side, and the other side updates automatically to show you the equivalent layout for the second manufacturer. The "Override" Logic: Turn off the Link to compare hardware variations. Want to see how an Alpha Pot layout differs from a CTS Pot layout for the exact same pickup? Simply override the link and toggle the hardware on one side. iPad Optimized: On the iPad, Compare Mode utilizes the full screen width to give you a massive, clear view of both schematics—perfect for having your device on the workbench while you solder. DESIGNED FOR THE WORKBENCH iPad Optimized: A unified notes field and side-by-side Compare Mode take full advantage of the larger screen. No Subscription Fatigue: Get lifetime access to the full suite of features with a one-time Pro purchase. CoilSense: Accuracy you can trust, right at your soldering station.

Verdict

The call

The clearest difference is price: Marker Player at Free against CoilSense's $9.99. Marker Player also leads on iOS requirement (15.6 vs 17.2). CoilSense's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
