Pomodoro AI vs Dioptra

Pomodoro AI is a calm, exact timer for deep work, with intelligence that runs entirely on your device. Run clean Pomodoro cycles: 25/5 by default, or build your own. A Live Activity keeps the timer on the Lock Screen and in the Dynamic Island, notifications land exactly when a phase ends, and a paused or closed session picks up right where you left it. Then it goes further. From your own session history, on your device, Pomodoro AI plans your day and tells you what you cannot see yourself: which hours you really focus, which days you drift, and what to change. DESIGNED FOR IPHONE DUO A glanceable, one-hand timer on the cover display. Unfold it and the timer, today's plan and your insights sit side by side on the inner display. Folding never interrupts a running session. Just as careful on every iPhone and on iPad. FREE • Unlimited Pomodoro cycles • Custom focus and break lengths • Today's plan: how many blocks to run and your best window, from your own history • Live Activity, Lock Screen and Dynamic Island • Today's history PRO — one-time unlock, no subscription • Weekly review written on your device, with three concrete recommendations • Analytics across weeks and months, by kind of work • A suggestion for every break • Optional reminder for your best focus window • Preset cycles: Deep Work 50/10, Study 45/15, ADHD-friendly 15/5 • Home Screen widgets, themes and sounds Private by design. Every number comes from your own sessions and is computed on your device. Nothing is uploaded. No account. No tracking. Requires iOS 26. On-device intelligence features use the system's on-device model when it is available and fall back to clear, fixed text when it is not.

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.
