Does Ollara Studio support full 4,096-level stylus pressure sensitivity?

Yes. Ollara Studio reads unquantized 32-bit floating-point pressure and historical motion samples directly from Android MotionEvents (and Web PointerEvents), supporting 4,096 and 8,192 pressure levels on Samsung S-Pen, Wacom EMR, USI 2.0, and Pixel Tablet styluses.

How does True Hand Lock palm rejection work when my hand rests on the glass?

Ollara Studio scans all active pointers in every touch frame to isolate TOOL_TYPE_STYLUS and TOOL_TYPE_ERASER even while your palm rests on the screen, automatically engaging Hand Lock with an 1,800ms pen-lift grace window so resting hands never leave stray marks.

Is Ollara Studio Pro a subscription or a one-time purchase?

Ollara Studio Pro is a one-time $7.99 lifetime unlock with zero ads and zero mandatory subscriptions. Optional cloud sync, AI photo-to-coloring conversion, and printed hardcover keepsake books are available separately.

WHY ARTISTS & FAMILIES SWITCH

Everything Wacom Bamboo Paper left out—without the subscription trap.

Legacy notebook apps lock basic brushes behind microtransactions and lack layers or symmetry, while kids' coloring apps charge $7.99/week and bombard tablets with ads. Ollara Studio unites both worlds.

ENGINEERED FOR 120HZ / 240Hz DISPLAYS

Precision ink physics meets effortless family creativity.

Every stroke in Ollara Studio is stored in normalized 1000×1000 vector studio coordinates, preserving hairline-to-bold calligraphy from phone screens to print-ready PDFs.

STYLUS ARCHITECTURE · v1.1.1

Zero-Recomposition 120Hz/240Hz Ink Pipeline

Traditional Android Compose drawing apps lag because every stylus movement triggers a UI tree recomposition and redraws hundreds of past strokes. Ollara Studio v1.1.1 caches committed layers and paper grids into an offscreen hardware bitmap, coalesces quadratic Bezier pressure paths within 0.45px, and renders only the active tip in real time.

PALM REJECTION · HAND LOCK

True Multi-Pointer Stylus Isolation

Rest your hand naturally on the glass before your pen even touches down. Ollara Studio scans every pointer in the touch frame to extract TOOL_TYPE_STYLUS and TOOL_TYPE_ERASER while locking out stray palm contacts with an automatic 1,800ms pen-lift grace window.

FREQUENTLY ASKED QUESTIONS

Everything you need to know about Ollara Studio.

Does Ollara Studio truly support 4,096 levels of stylus pressure sensitivity? ＋

Yes. Ollara Studio reads unquantized 32-bit IEEE 754 floating-point pressure values directly from Android's MotionEvent.getPressure() and historical batch samples (getHistoricalPressure()), supporting 4,096 and 8,192 pressure levels across Samsung S-Pen, Wacom EMR, USI 2.0 Chromebooks, and Pixel Tablet styluses. Both stroke width (0.22x to 2.25x) and pigment opacity respond dynamically to your pressure and stroke velocity.

How does True Hand Lock prevent my resting palm from drawing or moving the page? ＋

When your palm touches the screen before or during stylus contact, standard touch listeners get confused by pointer index 0. Ollara Studio's findStylusPointerIndex() scans all pointers in every frame to isolate TOOL_TYPE_STYLUS and TOOL_TYPE_ERASER, automatically engages 🔒 Hand Lock, and maintains an 1,800ms pen-lift grace window so resting hands never cause stray marks.

Can kids color inside templates without painting over the black line art? ＋

Yes! Built-in vector coloring overlays (like Royal Unicorn & Castle, Bamboo Forest Panda, Galactic Space Rocket, and Sacred Lotus Mandala) render crisp above your paint layers, so watercolor washes, crayon shading, and neon glow stay cleanly underneath the line art.

How do I install Ollara Studio on my Android tablet or phone right now? ＋

Tap Download Android APK (v1.1.1) at the top or bottom of this page to install directly, or open Brannan App Hub on any family device for 1-tap OTA installation and updates. You can also launch the companion Web Studio immediately in any browser at /studio/app.
