Castlerama takes you on a photorealistic walk through a beautiful, detailed and accurately lit 3D setting. Merging real and imaginary elements, it draws inspiration from the charming town of Assisi, in Italy. You are left to find your own way around by touch and sight alone. Exploring a whole world becomes a matter of lifting your fingers. Our goal? To fool your eyes and brain considering it all real. When you go back with your memory to the day you first opened this Mentalbox, you will think it was you on the cobblestone, you in the alleys, you in the catacombs... While developing Castlerama, we had to face the fact that newer devices such as iPhone4s and iPad2s are very different from their predecessors, iPhone3GSs and iPads, in that the former have twice as much memory. In order to have the app run on all devices, we had to compromise quite a bit, pushing the old devices to their limits (risking crash if other applications are left running) while keeping the new devices well behind their capabilities. Powered by Unreal Engine.

nanoTV is a professional media player designed for Mac, Apple TV, iPhone, and iPad. We combine powerful features with a clean interface so you can enjoy your own live and on-demand sources on any screen — an nanoTV assistant that finds channels and takes action, real-time subtitles in English, Chinese, and Japanese, 50p deinterlacing for smooth motion, and hardware-accelerated playback. Sources, favorites, and channel tags stay in sync across your devices with iCloud. KEY FEATURES 1. NanoTV Assistant Not just answers — it gets things done. Search channels and start playback, look up a program in the guide, set reminders, add or edit playlist and portal sources, and manage favorites, recents, and channel tags. Enable it in Settings → Assistant. 2. AI Real-time Subtitles Live transcription for English, Chinese (Mandarin), and Japanese — processed entirely on your device, so audio never leaves it. Translate into your language in real time. Subtitle size adapts to the player window, with frosted-glass or feathered backgrounds for clean, readable text. 3. Multi-engine Subtitle Translation Choose the engine that fits you: Apple on-device translation (Mac and iPhone/iPad), large language models (LLM), other supported translation services, or your own self-hosted API. Translate live AI subtitles or the subtitle tracks that come with a source. 4. Professional Playback Engine YADIF 2x deinterlacing turns 1080i 25fps into smooth 50p — great for fast-moving footage. Hardware-accelerated H.264/H.265 up to 4K and 8K (macOS), fast HLS start-up, and an adjustable buffer for live streams. On Apple TV, output matches the source frame rate and dynamic range (SDR/HDR/HLG), with experimental multichannel audio output. 5. Multi-format Sources Works with standard M3U playlists and common media portal protocols. Paste one or more URLs with Text Import, auto-refresh sources at launch, share any source as a QR code, and import from web or other Apps. 6. Channel Tags Your categories, your rules. One tag can hold channels from any source, and a channel can belong to several tags at once. Colors, symbols, and badges, with drag-to-reorder (move up/down on Apple TV). Tags sync via iCloud. 7. Electronic Program Guide (EPG) & Reminders Zoom the guide to see more channels or more hours, browse posters and categories, translate program information, and refresh the guide together with your sources. Long-press an upcoming program to set a reminder — or ask the AI assistant to create one. 8. Global Search & Quick Access Search channels and programs across every source at once. Favorites, recently played, and Quick Play (paste a link and watch immediately; on Apple TV, scan a QR code). Start from a favorite and channel switching stays inside your favorites. 9. Immersive Preview on Apple TV The Apple TV home screen and TV Guide preview the channel you are browsing, so you can see what is playing before you commit. 10. Remote Management & Network Add sources from a computer or phone, including QR-code add for supported portal protocols. SOCKS5 and HTTP proxy support plus a per-source User-Agent for networks that require them. 11. iCloud Sync Keep sources, favorites, and channel tags in sync across Mac, iPhone, iPad, and Apple TV, with a clear sync log. 12. Multi-language UI & Appearance The interface is available in English, Simplified and Traditional Chinese, Japanese, Korean, French, Russian, Vietnamese, Arabic, and more. Light, Dark, and System appearance modes, plus adaptive channel grids. nanoTV is a media player. It does not provide, host, or bundle any media content, playlists, or channels. Please add your own legally obtained playlists and sources.
