Application matrix / 12 studio apps • 11 live on the App Store
This hub indexes the studio. 11 of the 12 install straight from Apple's App Store — every card below carries its listing link. Each app also owns a host for the full product story and privacy details: new product pages live on *.makerportal.ai, and the ones still on makersportal.com/apps are being migrated transparently.
Before the catalog
Every coefficient and every vertex below is solved — on the server for the first paint, then in your browser on every drag — byrbjCoeffs andfreqResponse — the same two functions behind the full cascade designer, the 248 published designsand /api/v1/biquad-design. Nothing is fetched and nothing is fitted. Sample rate 48 kHz.
This type reads f₀, Q and gain.
Normalised to a0 = 1 · 6.00 dB at f₀
b0 = 1.022472768 b1 = -1.938116581 b2 = 0.932367744 a1 = -1.938116581 a2 = 0.954840512

Add &include=curve for the 240-point response. Twelve of the cards below are the on-device half of the same work.
Most apps share the same local stack: CoreML, Metal, ANE, ONNX. AuraLinter adds transparent cloud for agentic DSP — audio upload, SSE streaming, clang++ verification. No dark patterns.
Productivity • On-device executive presence coach
Private executive presence coach that runs entirely on-device: rehearse out loud and get timestamped findings with audio receipts, live pace coaching, a teleprompter that listens, and The Room — mock interviews with five neural interviewers. One-time purchase, no account, no cloud.

Game • AI-powered speed-texting battleground
AI-powered speed-texting battleground: local LLM pipeline SmolLM2-360M-Instruct, precision mach-time keystroke tracking, Levenshtein scoring — entirely through llama.cpp + Metal on-device. No cloud reads your input.
Audio • Real-time identity-shifting vocal engine
Real-time identity-shifting vocal engine: kNN-VC neural pipeline, WavLM-Large feature extraction, cosine nearest-neighbor matching, HiFiGAN vocoding via ONNX Runtime on-device. Custom voice banks in under a minute.
Productivity • A private open loops ledger for your spoken word
A distraction-free markdown note-taking workspace equipped with local vector embeddings and semantic search that indexes your thoughts entirely offline.
Audio • Generative audio engine for ANE
Professional-grade generative audio engine: Diffusion Transformer optimized for Apple Neural Engine, binaural focus-scapes, meditation frequencies, neural noise — all private prompt-to-soundscape on-device.
Lifestyle • Intelligent wardrobe indexing & capsule design
Visual wardrobe tracking powered by on-device computer vision to auto-categorize apparel, extract color palettes, and build capsules.
Productivity • On-device LLM with Metal acceleration
State-of-the-art on-device AI: Metal GPU + llama.cpp, local language models offline, zero data to cloud — debug code, brainstorm prose, solve problems on flights, all privately on iPhone + iPad.
Game • AI word game — Spell Bound + Lexify + Crossword Dash
AI-powered word game: Spell Bound, Lexify, Crossword Dash — endless vocabulary puzzles, brain training, AI-generated crosswords for all skill levels, 100% on-device.
Developer Tool • Headphone Motion API + Spatial Audio
Leverage Headphone Motion API (iOS 16) for real-time AirPods Pro head tracking: Spatial Audio prototyping, head-controlled interfaces, researcher data capture — direct low-latency sensor access on-device.
Utility • BLE Arduino control — HM-10, nRF52, CSV export
Bluetooth Low Energy Arduino control: real-time pin control, live data plotting, raw serial terminal, CSV export — HM-10/CC254x/nRF52 modules, iPhone to hardware with zero cloud dependency.
App Store prices are as Apple reported them on 18 September 2026 and are indicative only — the price shown on the App Store at the time of purchase applies.

Future-proof AppSwitcher — drop into subdomains
All 12 share the same local intelligence stack: CoreML, Metal, ANE, ONNX, llama.cpp. Zero cloud for inference where possible. 6 product pages still bridge via makersportal.com/apps ↗ until they migrate to *.makerportal.ai — a hosting detail, not a shorter catalog: every one of those titles is live on the App Store today. Use the switcher above in any subdomain header — theme-aware, no backdrop-filter.
