ManimStudio
Windows · iOS · v1.1.3.0A GUI for creating mathematical animations with Manim — bundled Python and MiKTeX, no admin rights. On the Microsoft Store and App Store.
CodeBench Local AI
iPad · Mac CatalystA self-contained, offline dev / scientific / AI workstation — Monaco editor, integrated terminal, Python 3.14 + C/C++/Fortran, on-device pdflatex, and local LLMs via llama.cpp.
python-ios-lib 30+ libs
Python 3.14 · iOS arm64A full Python runtime for iOS with the first public native PyTorch build, HuggingFace transformers, Rust tokenizers, NumPy/SciPy/scikit-learn, manim, and C/C++/Fortran interpreters. Powers CodeBench.
EigenDenoise & Generalized Covariance
macOS · Windows · two storesMy Yau-award research shipped as software, twice. EigenDenoise is a Metal-accelerated macOS image denoiser built on random matrix theory; Generalized Covariance Matrix is the Windows research tool for eigenvalue spectral distributions — analyse ESDs, visualise spectral densities and export results, fully offline.
Bootbox
iOS · iPadOSA boot manager for your iPad. It boots real operating systems — 64-bit Linux, classic Windows, graphical desktops — inside a WebKit-hosted emulation stack, with real internet and real multi-core. Everything runs on-device: no servers, no streaming, no jailbreak.
SidecarBridge
iOS · App StoreA secure remote window into your Mac, with iPhone and iPad keyboard, trackpad, touch and Apple Pencil input. Everything stays on your own network — the Mac's screen is never published to the Internet.
Typhoon Forecasting AI Trackformer
causal · +120 h · western PacificMy own tropical-cyclone model: track, central pressure, intensity and the wind-field radii five days out. It reads analysis fields valid at or before the issue time — never a forecast field, and never another agency's track. Live on the tracks explorer over real JMA forecasts and past storms.
GPS-location-app
iPhone · Apple WatchPrecision GPS workout tracker. Kalman-filtered location, HealthKit sync, Live Activities, CarPlay and route analytics in a clean SwiftUI interface.
python-to-binary no deps
compiler · stdlib onlyA compiler and application builder written with nothing but the Python standard library. It turns Python into real machine code — and where it needs C in the middle, it compiles that C with a C compiler it also wrote. No Cython, Nuitka, Rust, gcc or clang at any point.
Apple Foundation Model Teardown
reverse engineering · paperA static reverse-engineering of Apple's on-device foundation model — the sparse Mixture-of-Experts backbone in Apple Intelligence — decoded from its container formats down to a component-validated PyTorch forward pass. Original research only: no Apple weights or tokenizer are redistributed.
