FileBox vs Aero Lab Suite

File Box brings file management, media playback, ebook and comic reading, and handy tools into one app, making it easy to organize, view and work with your files on iPhone and iPad. Store files in the app, lock it with Face ID or a password, or grant access to files in system folders. From work documents and photos to videos, music, ebooks and comics, keep everything in your own “Box,” ready whenever you need it. Keep your files organized • Use “On My iPhone/iPad” to browse, play and manage files in authorized system folders without importing them into the app. • Import, move, copy, rename, search and share files and folders with ease. • Customize folder colors, icons and images to make categories easy to spot. • Create ZIP archives and extract common formats such as ZIP and RAR, with support for password-protected archives. • View storage usage by file type, large files and duplicates, including in authorized system folders. • View and clear reading and thumbnail caches without affecting your files or reading history. Enjoy videos and music • Play common video formats including MP4, MOV, MKV, AVI and WebM, with audio track switching and Picture in Picture. • Press and hold the screen to speed up playback at your preferred rate. • Use dual subtitles, external subtitles and customizable subtitle styles, or cast videos to compatible TVs. • The new audio player shows artwork and lyrics, with playlists, shuffle and Lock Screen controls. Read ebooks and documents • The EPUB reader offers a table of contents, bookmarks, search and saved reading progress. • Adjust font size, layout and reading themes for comfortable reading. • View PDF and TXT documents, and add bookmarks to TXT files. Read and create comics • Read CBZ and CBR comics, or open image folders directly as comics. • Create your own CBZ comic files, with optional passwords and text watermarks. Redact images and share with confidence • Detect faces, QR codes and common sensitive details such as names, phone numbers and amounts on your device. Choose which categories to redact. • Select areas manually and choose from styles such as blur and pixelation, or add text watermarks. • Select “Redact Image” from the Photos share sheet and save the edited image directly to Photos. Keep useful tools close at hand • Browse and edit images, compress them in batches, and create long screenshots from web pages, multiple images or screen recordings. • Trim, split, join and convert audio, or extract audio from videos. • Edit audio artwork, song details and lyrics, including batch editing. • Crop and trim videos, and convert between MP4 and MOV formats. • Turn multiple images into a PDF, add watermarks or password-protect PDFs. Transfer files across devices • Use Nearby Transfer to easily send and receive files with nearby devices. • Upload, download, manage and preview files in your computer’s browser over your local Wi-Fi network. • Record audio on Apple Watch and sync recordings to iPhone. • Import files shared from other apps, with drag and drop and multitasking for browsing and playback.

Aero Lab Suite is a comprehensive, interactive pocket laboratory designed for aerospace enthusiasts, students, and engineers. Explore the fundamentals of orbital mechanics, atmospheric aerodynamics, and rocket propulsion through four powerful, real-time simulation tools. KEY SIMULATION MODULES: 1. FLIGHT TRAJECTORY SIMULATOR • Real-time trajectory plotting on an interactive coordinate grid. • Dynamic HUD displaying altitude, velocity, flight time, and acceleration. • Full control over launch angle (0–90°), engine thrust (10–100%), and crosswind vectors (-10 to +10 m/s). • Accurate physics modeling accounting for gravity, atmospheric drag, and thrust-to-weight ratios. 2. DELTA-V & ORBITAL CALCULATOR • Precise Delta-V computation powered by Tsiolkovsky’s rocket equation. • Interactive mass parameters: wet mass, dry mass, and specific impulse (Isp). • Visual propellant mass fraction breakdown chart. • Instant capability assessment: Suborbital, Low Earth Orbit (LEO), or Interplanetary capability indicators. 3. AERODYNAMICS & DRAG ANALYZER • Multi-geometry drag analysis: Cone, Sphere, Cylinder, and Flat Plate. • Variable flow velocity (1–1000 m/s) and atmospheric density settings (strato to sea level). • Real-time airflow line animations illustrating boundary layer behavior. • Live calculation of Drag Force (N) and Reynolds Number. 4. PROPULSION ENGINE DATABASE • Detailed catalog of operational and historical rocket engines (Raptor, Merlin, RS-25, F-1, RD-180, and more). • Comprehensive technical sheets: thrust ratings, Isp efficiency, propellant types (Kerolox, Methalox, Hydrolox). • Search and filter capabilities by engine name, manufacturer, and fuel mixture. • Thrust vs. altitude performance curves. DESIGNED FOR PERFORMANCE & OFFSETS: • 100% Offline Capability: All physics solvers and databases are embedded directly on your device. • Zero Latency: Haptic feedback and instantaneous slider response for immediate visual feedback.
