Calc vs Captured!

Calc-U-59 is a TI-59, TI-58, and TI-58C emulator for iPhone, iPad, and Mac. It runs the original ROM, so every program, module, and quirk works exactly as it did on the real hardware — with virtual magnetic cards, a PC-100C printer, all fourteen Solid State Software modules, and a CPU-level debugger for anyone who wants to look under the hood. CYCLE-ACCURATE EMULATION The TMC0501 processor is emulated at the cycle level, reproducing the exact behaviour of the original hardware — including the TI-58C's constant memory, preserved across restarts. The Master Library ROM and many more modules are included. INTEGRATED DEBUGGER Inspect program memory, data registers, CPU state, and internal SCOM registers live as the machine runs. Step through instructions one at a time, or let the emulator run and freeze it at any point. You can even run your own assembly programs! Available on iPad (landscape) and Mac. PAPER TAPE PRINTER A functional recreation of the PC-100C thermal printer with dot-matrix font rendering. Trace exactly what programs print and why. Copy output as plain text or as a high-resolution bitmap. MAGNETIC CARD READER Load and save programs and data registers as card files, stored on your device and synced via iCloud. Bring old listings back to life and run them under the debugger. STATE FILES Load .ti59 and .ti58(c) state files to instantly configure the machine with a program, registers, and flags — ideal for sharing reproducible scenarios or revisiting known machine states. SOLID STATE MODULES Select a Solid State Module and run programs from there. Whether you're bringing an old program back to life, running the Master Library modules, or exploring how these machines actually worked under the hood, Calc-U-59 gives you a faithful TI-59 in your pocket.

Tired of losing links, photos, videos, audio, files or texts shared from your apps? Captured is your universal clipboard. Tap Share from any app and choose Captured — everything is instantly saved, previewed and enriched, on-device by default. UNIVERSAL CAPTURE Accepts URLs, photos, videos, audio, files and text from any app. Automatic source detection (Safari, YouTube, Instagram, X, Photos...). AUTO-GENERATED PREVIEWS Every item gets a thumbnail: web pages via live browser, photos/videos from first frame, files via QuickLook, audio as waveform, text as typographic render. Thumbnail gallery with on-demand regeneration. AI DESCRIPTION, OCR & TRANSCRIPTION AI image/video description: Apple Vision (free, on-device), OpenAI GPT-4 Vision or Anthropic Claude. Built-in OCR on photos and videos. Audio speech-to-text transcription — all on-device by default, no cloud required. SMART ORGANIZATION Folders with batch move/delete and drag-and-drop reorder. Smart Views: All, Recent (7 days), Unread, With Location, With AI. Configurable sort: manual, newest, oldest, title, source. Filter by type: URL, file, photo, video, audio, text. FULL-TEXT SEARCH & SPOTLIGHT Instant search across titles, URLs, notes, AI descriptions and transcriptions. All items indexed in system Spotlight — searchable from the home screen. RICH METADATA Auto-fetch of web page title and last-modified date (bold title signals updated content). Reverse geocoding of GPS coordinates in photos. WIDGET WidgetKit widget in small, medium and large sizes showing unread items in real time. BACKUP & RESTORE Full JSON export/import (items, folders, settings, thumbnails) with Replace or Merge mode. PRIVACY All your data stays on your device. No account, no server, no ads. Network calls only when you explicitly enable web fetching or AI description via your own API key. iCloud sync, folder by folder Choose exactly which folders you want to find on your other devices. A long press on a folder offers "Sync with iCloud": its photos, videos, files and links — including previews — automatically appear on your iPhone, iPad and Mac linked to the same Apple account. Folders that are not synced remain strictly local. A "Resync iCloud" option lets you reconcile state across devices in one gesture. Link previews: lock, zoom, crop You can now lock a link's preview so it never changes, or enlarge the preview by a factor of 2 to better see thumbnails from your favorite sites. A new setting automatically crops the white or black bands surrounding some previews. Organization: everything by drag-and-drop Reorganize your folders by dragging them in the sidebar. Move an item from one folder to another simply by dragging it onto the destination folder. No more drop-down menus. Paste a link from the clipboard A new menu entry lets you directly add the currently copied link, without going through another app's "Share" menu. Manage your space better The info panel now shows the space used in iCloud when sync is active. A long press on each line gives access to quick actions. The "Delete local data only" option frees up space while keeping your synced folders intact.
