The WiWU Pencil S-04 is a versatile smart stylus engineered to be the only pen you need — combining a dedicated Apple mode for iPad with a Universal mode for Android tablets and other capacitive touch devices in a single stylus with palm rejection, tilt sensitivity, pressure sensitivity, magnetic attachment, and up to 10 hours of continuous battery life. Whether you're sketching on an iPad Pro, taking notes on an iPad Air, annotating on an Android tablet, or navigating any capacitive touchscreen, the S-04 switches seamlessly between modes for a consistent, natural pen-on-paper experience across every device you own.
SMART DUAL-SYSTEM — APPLE MODE + UNIVERSAL MODE
The defining feature of the WiWU Pencil S-04 is its innovative dual-system architecture — two distinct operating modes built into a single stylus:
Apple Mode: a dedicated, optimised connection protocol for compatible iPads — delivering pixel-perfect precision, zero-latency performance, palm rejection, tilt sensitivity, and pressure sensitivity that takes full advantage of the iPad's stylus input capabilities. Apple mode provides the responsive, natural writing experience that iPad users expect from a professional stylus — without the Apple Pencil's price premium.
Universal Mode: a capacitive stylus mode compatible with Android tablets, Samsung Galaxy Tab series, other Android touch devices, and any other capacitive touchscreen — covering the full spectrum of modern tablets and touch-enabled devices regardless of operating system. Universal mode enables the S-04 to function as a precision stylus on non-Apple devices, extending its utility across every touchscreen in a multi-device household or professional setup.
Switching between modes is seamless — a single hardware action activates the appropriate mode for the connected device, eliminating the need to carry a separate Apple stylus and a separate Android stylus.
PALM REJECTION — REST YOUR HAND NATURALLY ON THE SCREEN
Advanced palm rejection technology allows you to rest your hand naturally on the screen while writing or drawing — the device only registers input from the stylus tip, ignoring accidental palm and wrist contact completely. Palm rejection is the feature that separates professional stylus performance from basic capacitive pens — without it, resting your hand on the screen while writing creates unwanted marks, accidental gestures, and navigation errors that interrupt creative and productive workflow. With palm rejection, handwriting and sketching feel as natural as writing with a physical pen on paper.
TILT SENSITIVITY — EXPRESSIVE LINE VARIATION AND SHADING
Tilt sensitivity detects the angle of the stylus relative to the screen surface and adjusts line weight, opacity, and shading accordingly — replicating the natural variation of a physical pencil or brush. Tilting the stylus produces wider, softer strokes ideal for shading, hatching, and blending; holding it upright produces precise, thin lines for outlines, annotation, and fine detail. For digital artists and illustrators, tilt sensitivity is a fundamental tool for expressive, dynamic artwork that conveys depth, texture, and dimension.
PRESSURE SENSITIVITY — VARIABLE LINE WEIGHT ON TOUCH
Pressure sensitivity responds to the force applied to the stylus tip — lighter pressure produces thinner, lighter strokes while heavier pressure produces bolder, thicker lines. Combined with tilt sensitivity, pressure sensitivity enables the full range of traditional drawing and writing expression in digital form — from delicate hairlines to confident, weighted strokes — across compatible apps and devices that support pressure input.
PIXEL-PERFECT PRECISION — ZERO-LATENCY PERFORMANCE
The S-04 delivers pixel-perfect precision with zero-latency performance — every stroke is captured and rendered exactly where the stylus tip contacts the screen, without the cursor lag or position offset that affects basic capacitive styluses. Zero latency ensures that handwriting looks exactly as written, sketching lines appear exactly as drawn, and navigation feels immediately responsive — the precision standard required for professional-quality digital work.
MAGNETIC ATTACHMENT — ALWAYS AT HAND, NEVER LOST
The S-04 attaches magnetically to the side of compatible iPads — keeping the stylus securely fixed to the device between uses without requiring a case, clip, or separate storage solution. Magnetic attachment eliminates the risk of losing the stylus in a bag, and ensures it is always within reach when needed for a quick annotation, sketch, or note.
10-HOUR BATTERY LIFE — ALL-DAY CREATIVITY
Up to 10 hours of continuous use per charge provides battery coverage for full workdays and extended creative sessions without interruption. The long battery life means the S-04 is ready for use across multiple days of moderate use between charges — reducing the frequency of charge interruptions that disrupt workflow continuity.
