NetStability is a network stability trend analysis tool that helps you understand how reliable your internet connection is over time — not just right now, but across hours, days, and weeks. Unlike traditional network tools that show you a snapshot of your current connection, NetStability focuses on historical patterns, fluctuation trends, and connection reliability through local data collection and visualization. WHAT MAKES NETSTABILITY DIFFERENT • Trend-Focused Analysis — View stability scores across 24 hours, 7 days, or 30 days to understand your network's long-term behavior • Stability Scoring — Get a clear percentage-based stability score that reflects both connectivity uptime and latency consistency • Smart Insights — Receive actionable recommendations based on your network's historical performance, like whether conditions are suitable for video calls • Latency Tracking — Monitor latency fluctuations over time, not just a single measurement • Disconnection History — Track when and how often your connection drops WHO IS IT FOR • Remote workers who need reliable connections for video meetings • Students preparing for online exams or interviews • Streamers and gamers who need consistent network quality • Anyone who wants to evaluate their home or office network reliability over time KEY FEATURES ○ Dashboard — At-a-glance view of your current stability score, 7-day performance, disconnection count, average latency, and fluctuation level ○ Trends — Interactive charts showing stability, latency, and disconnection trends across configurable time ranges ○ Insights — AI-free, rule-based analysis that provides plain-language conclusions about your network's health and suitability for specific activities ○ Monitoring Control — Start and stop monitoring sessions with configurable measurement intervals ○ Privacy First — All data is collected, stored, and analyzed entirely on your device. Nothing is uploaded or shared. TECHNICAL DETAILS • Uses Apple's Network.framework for connectivity monitoring • Lightweight latency measurements via standard HTTP requests to public endpoints • Local-only data storage with configurable retention (7–90 days) • Supports Dark Mode • Optimized for iPhone and iPad NetStability gives you the data to answer: "Is my network reliable enough for what I need to do?"

Give text a voice—entirely on your iPhone. FrankenTTS is a private, on-device text-to-speech and voice-cloning playground powered by a pure-Rust speech engine. After a one-time 1.86 GB model download, synthesis runs locally with no cloud inference. • Choose from built-in voices • Clone a voice from a short microphone recording, with a live level meter and automatic background-noise removal • Keep cloned voices in a private on-device voice library; rename, re-record, or delete them whenever you like • Share and import FrankenTTS voice cards—each carries a compact 4 KB voice fingerprint, never the original recording • Generate speech with an editable random seed • See the measured real-time factor for every run • View the waveform, play audio, and share compact M4A files • Turn generated speech into a branded MP4 video • Resume interrupted model downloads with SHA-256 verification Privacy is the default: entered text, microphone audio, voice fingerprints, imported pictures, and synthesized speech are not uploaded. Enrollment recordings are discarded after their on-device voice fingerprint is computed. Voice-card sharing and media export happen only when you explicitly choose them. Only clone or share voices you have the right and consent to use. A recent high-memory iPhone is strongly recommended.
