NOTES & REMINDERS, PERFECTLY COMBINED Why switch between a notes app and a reminders app? With Tags & Notes, every note is built from modular blocks. You can write down a brilliant idea, attach a checklist, and drop in a scheduled reminder right next to it—all inside the same note. Absolute focus, zero friction. SEAMLESS iCLOUD SYNC Your ideas, wherever you go. Whether you're jotting down a quick thought on your iPhone, reviewing tasks on your iPad, or organizing your week on your Mac, Tags & Notes synchronizes instantly and securely via iCloud. Start on one device and finish on another without missing a beat. TAGS THAT ACTUALLY WORK Organize your world with custom color-coded tags. Filter your entire library instantly with a single tap. Toggle between All, Tagless, or any custom combination using powerful multi-select support. POWERFUL, FLEXIBLE REMINDERS Never let a deadline slip. Set one-time or recurring reminders—hourly, daily, weekly, monthly, yearly, or fully custom intervals—directly inside your notes. Missed a reminder? Tags & Notes tracks past-due items automatically so you stay on top of everything. INTERACTIVE CALENDAR VIEW Visualize your entire schedule on a beautiful calendar. Tap any day to see exactly what notes and reminders are scheduled, instantly sorted and filtered exactly how you want. HOME SCREEN WIDGETS Glance at today's upcoming deadlines or quickly access your most recent notes right from your Home Screen, without even opening the app. BUILT FOR PRODIGIOUS FOCUS • Reorder notes and blocks with intuitive drag-and-drop controls. • Lock individual blocks to protect your important entries from accidental edits. • Lightning-fast search across all your notes and individual blocks. • A Recently Deleted bin keeps your discarded notes safe for 30 days. • Tap any notification to navigate directly to the exact reminder inside your note. Tags & Notes gets out of your way and lets you capture what matters most.

Gadeon runs Qwen3.5 and QwenPaw hybrid language models entirely on your device's Apple Neural Engine, using Core ML as its only framework dependency. There's no C, no Python, and no cloud calls: every token is generated locally, keeping your conversations private. Under the hood, these models mix Gated DeltaNet recurrent layers with a smaller number of attention layers. Gadeon compiles that hybrid architecture directly onto the Neural Engine's dataflow accelerator, so both prompt processing (prefill) and token generation (decode) run on-chip instead of falling back to the CPU or GPU. On an Apple Silicon Mac, prefill measures roughly 2 to 2.4 times faster and about 4.4 times more energy-efficient per token than a Metal GPU baseline, while leaving the GPU free for other work. Conversations in Gadeon are append-only: each turn extends the model's fixed-size recurrent state instead of re-processing the entire chat history, so response latency doesn't grow as a conversation gets longer. The app can also roll back to an earlier point in a conversation, dropping reasoning traces or replaying tool calls in a clean form without reprocessing everything from scratch. For ternary-quantized models, Gadeon switches to a pure-Swift Metal GPU backend behind the same session and tokenizer interface, so both compute paths feel identical from the chat UI. Gadeon is a proof of concept for bringing Gated DeltaNet hybrid models to the Neural Engine through Core ML - built to explore what's possible on Apple's own silicon.
