Create beautiful vector artwork on your iPad with Inkpad. Draw with accuracy and speed. Quickly align new or existing objects either to a grid, points, or path edges. Alternatively draw freehand bezier paths using the brush tool. Select, scale and rotate hundreds of objects with high performance in real time. Cutout elements of artwork, photographs or patterns with masks. Flexible typography effects. Position text at any angle or to follow along paths. Apply multiple effects to text, with stroke, fill, shadow and opacity all dynamically adjustable. If the over seventy built in fonts don’t quite fit your design, you can import any of the millions of OpenType and TrueType fonts available. Take control with unlimited layers. Feel free to add as many or as few elements in each layer to organise your drawings. Rename, rearrange, delete, hide and lock layers as you draw. Isolate the active layer for easy editing. Adjust each layers transparency independently to get your ideal composition. Powerful editing at your fingertips. Easily manipulate single or multiple elements with powerful scale and rotate tools. Associate individual elements into groups. Interactively edit gradient fills on the canvas. Perform a range of Boolean operations on paths, including Unite, Intersect, Exclude and Subtract Front. Colors to match your imagination. Picking the perfect color is easy with the freedom of the expressive color wheel. Or modify colors using RGB and HSB sliders. Enter the hexadecimal value to precisely match existing artwork colors. Sample colors using the dropper. Store and recall colors from the swatch library. Import, export and sharing. Import drawings from desktop vector applications as SVG and include photos directly from your camera roll, or import PNG and JPEG images from cloud services. Export your drawings for sharing or importing into other apps as SVG, PDF, PNG and JPEG to all cloud storage services. Send drawings as photos directly to your camera roll. Light & dark modes. Light and dark mode system appearances with the option to override the system setting to light or dark mode for Inkpad. Apple Pencil. If you’ve got an iPad Pro or the 2018 iPad, Inkpad works great with the Apple Pencil. Praise for Inkpad. Some of the kind feedback received in emails and App Store reviews: “Works perfect on latest iPad Pro, Apple Pencil.” “It’s really beautiful to use with an iPad Pro.” “Inkpad is one of the killer apps for the iPad.” “Inkpad is my favorite graphics app on any platform. Inkpad is just the right balance of enough power without being too complicated.” “If you’ve worked with Illustrator or Inkscape, this is the vector drawing app to download for your iPad. Especially nice with the iPad Pro with Apple Pencil.” “I love this vector drawing app for its easy-to-use interface and pared-down tool bar. It covers the essentials perfectly and the developers are very responsive to questions.” “Inkpad is my main vector design tool for mobile. This is the app that Adobe Draw should be.” “Thank you guys, I use this app all the time.” “If you used to work with Inkpad in the past you should get this app to continue working with it.” Acknowledgements. Thank you to Martin Coffey, Rita Flores, Yve Müller, Armin Popp, David Rivera, Nicolas Saez, Erick Villagomez, Felipe Villela and Jason Wray for contributing artwork to the ‘Designed with Inkpad’ app preview video and screenshots.

I took over development because my wife Lindsay uses Inkpad and I wanted to ensure the continued development and support of a product we and others enjoy so much.

Features
Read full description

3DGS Viewer is a fast, private, fully offline viewer for 3D Gaussian Splatting scenes. Open your captures straight from your device and explore them in crisp, real-time 3D — no account, no cloud, no internet connection required. Built as a native rendering engine (not a web wrapper), it reads raw splat files directly from memory for instant loading and smooth navigation, even on scenes with millions of splats. WHY YOU'LL LOVE IT • Truly offline & private — no servers, no sign-in, no tracking, no data collection. Your 3D files never leave your device. • Broad format support — uncompressed .ply and .splat, plus compressed .spz (versions 1–4) and .sog. • Fast GPU rendering — WebGPU compute accelerates splat sorting where available, with automatic WebGL2 fallback on older devices. • Crisp, artifact-free edges — a custom viewing system removes the spiky shapes that ruin straight lines on balconies, railings and buildings. • Handles huge scenes — open multi‑million‑splat models with an adjustable Splat Limit to balance detail and performance. • View-dependent color — optional spherical-harmonics rendering (SPZ v4) for richer reflections and highlights. • Walk mode — move through your scene in first person. • Capture & share — save high-resolution photos, or record turntable and cinematic flythrough videos (MP4/H.264) straight to your Photos library. • Level & orientation tools — straighten a tilted scene or flip it right-side up in one tap. • Battery & thermal aware — the render loop eases off during static viewing to reduce power draw. OPEN FILES THE EASY WAY (iOS) Tap Open File and pick from Apple's Files screen — it shows every provider you have (On My iPhone/iPad, iCloud Drive, Google Drive, Dropbox, and more). ONE-TIME PURCHASE — NO SUBSCRIPTIONS, NO ADS Pay once and own it. Every feature is included — no subscriptions, no ads, no in-app purchases, and no data collection. PERFECT FOR Photogrammetry and 3D-scanning enthusiasts, real-estate and architecture visualization, VFX and research workflows, and anyone who wants to view Gaussian Splat captures on the go — completely offline.
