Spacebar Counter vs Dioptra

The iOS Spacebar Counter App (also known as the Counter Clicker App) that you can download from the App Store, was inspired by our popular online Spacebar Counter and molded to perfection with suggestions by our web visitors. Our visitors wanted a standalone application that does not require an Internet connection (unlike the online version), and they wanted to be able to count many things at the same time. We were happy to comply with visitors' requests. This app does not require the Internet after it has been installed on your device, and you can count up to four things at the same time. Its potential uses are endless. For example, use it to keep track of and count sports scores, family card games, board games, accomplishments, knitting progress, crochet tally, and so much more. We hope the Spacebar Counter App will become your go-to app for keeping track of and counting different fun activities in your life.

A 3D model viewer for iPhone and iPad that takes measurement seriously. Open a file, turn it over, and tap two points on the surface to get a real distance. FORMATS • glTF — .glb and .gltf • USD — .usdz, .usdc, .usda and .usd • STL — 3D prints and CAD exports, read in millimetres and turned upright • PLY — scans and photogrammetry, with per-vertex colour • VRM • Interactive pages — an .html export keeps its own controls and runs as it was built MEASURE • Tap two points for a true distance • Take as many measurements as you need; they stay listed with the model • Switch between metric and imperial whenever you like • Set what one file unit means: metres, centimetres, millimetres, inches or feet INSPECT • Orbit, pan and zoom, or leave it turning on its own • Wireframe, to see how a mesh is built • Studio, light and dark backgrounds • Play embedded animations, one clip at a time • Model info: width, height and depth, plus triangles, vertices, meshes, materials, textures, nodes and animations • Share a snapshot of the view ORGANISE • Folders, which appear in the Files app exactly as they do here • Search, sort by name, type or date, and switch between a list and a grid • Rename, drag a model onto a folder to file it, or delete it • Bring models in with the picker, from another app's share sheet, or by dropping them into the Dioptra folder in Files SAMPLES Six models come with the app, one for each kind of file it opens, all built to real-world scale: the ancient sighting instrument the app is named for, a Roman surveyor's groma, a sundial's gnomon, a tripod foot in millimetres, a surveyed patch of terrain, and an interactive plan of sight lines.
