Former consultant → independent builder.

I build simple, high-impact apps—and help teams turn ideas into working products.
From offline-first tools to AI-powered workflows.

Software

Independent apps

Screen time, focus, phonetics, and creative utilities—built offline-first where it matters.

Step1st app icon Step1st

iOS · Health & Fitness · Productivity · v1.0

A movement-driven iOS app blocker that links screen time to physical activity—using step goals before you scroll.

Currently in TestFlight — early access available

Unlock your apps, one step at a time.

Designed for desk-bound professionals and chronic doom-scrollers, Step1st uses physical step goals to break sedentary loops and enforce a "Move-to-Unlock" daily ritual. Step1st solves the modern dilemma of digital addiction coupled with physical inactivity. By linking screen time to movement, it ensures you hit your activity targets before surrendering to distractions. It’s not just an app locker; it’s a self-discipline engine for those who want to reclaim their health by making movement the prerequisite for entertainment.

  • Integrity-Based Locking: Uses Apple’s Screen Time API to keep distracting apps inaccessible until your steps are logged—eliminating the "Ignore Limit" loophole common in basic timers.
  • Frictionless Tracking: Leverages native motion co-processors for high-precision step counting with zero location tracking, protecting your privacy and your battery.
  • HealthKit Empowerment: Seamlessly syncs with Apple Health to provide a "Read-Only" experience, keeping your data local and under your total control.
  • Native Efficiency: Designed with a "Zero-Impact" philosophy—running ultra-lightweight in the background to ensure your iPhone stays fast and responsive.

TapPause app icon TapPause

iOS · Health & Fitness · v1.1

A minimalist breath and pause timer for seekers of digital peace—a gentle space to reset awareness amidst daily noise.

The most productive thing you can do is just be.

TapPause is an intentional ritual of non-doing—a quiet invitation to step out of the frantic stream of tasks and return to the present moment, fully offline.

See how to take a real break from your phone in a packed day:

  • Gentle ritual: One-tap to start; zero cognitive load.
  • Radical simplicity: No streaks, no rewards—rest is the goal.
  • Pure presence: 100% offline; your peace is yours alone.

PurrrrrFocus app icon PurrrrrFocus

iOS · iPhone & iPad · Productivity · Utilities · v2.5

A minimalist iOS Pomodoro timer with classical Chinese aesthetics and a cat companion—for deep work and ADHD-friendly focus.

Focus enhancement, wrapped in calmness.

PurrrrrFocus pairs a minimalist iOS Pomodoro timer with classical Chinese aesthetics and a cat companion system for ADHD users, students, and anyone chasing flow. Beyond the standard Pomodoro technique, it offers Elite Focus and Count-Up modes designed to reduce overwhelm—making it a perfect companion for deep work or ADHD support. It’s more than a utility; it’s a calm, user-friendly courtyard where your virtual cat grows alongside your focus habits.

See how PurrrrrFocus is used in real study routines:

  • Diverse Timer System: Includes Pomodoro, Count-Up, and Elite Focus modes to adapt to different task types and cognitive needs.
  • Classical Feline Companion: Features an adorable cat companion system and 6 classical themes inspired by traditional Chinese aesthetics.
  • ADHD-Friendly Design: Built with simplicity and tranquility in mind, focusing on reducing distraction and building consistent work habits without pressure.
  • Native Performance: A lightweight iOS/iPadOS experience with statistics, achievements, and beautiful widgets—100% focused on privacy.

TransMov app icon TransMov

macOS · Graphics & Design · Productivity · v2.0

A local-first macOS utility that extracts transparent animated assets from video—for UI designers and web developers.

A specialized layer for UI asset extraction.

TransMov is a local-first macOS utility for UI designers and web developers who need transparent animated assets from video—without cloud uploads. It sits between your source footage and production code, converting clips into transparent APNG or WebP locally on your Mac so sensitive brand assets stay on-device.

Understand different use cases and tradeoffs:

  • UI-Ready Transparency: Specialized in generating 8-bit alpha-blended assets to prevent the jagged edges common in traditional GIFs.
  • Local-Only Processing: Uses on-device AI via Apple Vision. Your source video stays 100% private, processed entirely on your machine.
  • Focused on Web Formats: Prioritizes modern web-native formats like APNG and WebP over cinematic video containers.
  • Fit for UI Workflows: Ideal for onboarding animations and product demos where privacy and web compatibility matter more than cinematic precision.

Phonetic Formatter app icon Phonetic Formatter

iOS · Tools · English · IPA · Linguistics · v1.2

An offline IPA transcription tool that turns English passages into structured, printable phonetic worksheets—100% on-device.

Stop fighting with flaky online converters and broken formatting.

Built for teachers, linguistics students, and serious learners, Phonetic Formatter turns full English passages into structured, printable phonetic worksheets. Paste a passage, generate word-aligned IPA in seconds, and export to PDF or Word—all 100% on-device. It’s the gold-standard CMU dictionary reimagined for educators who need to ship materials, not just look up single words.

See how teachers use offline IPA for classroom-ready handouts:

  • Built for Educators: Optimized for full-text processing and structured handouts.
  • Production Ready: Export to PDF, Word (DOCX), and TXT for immediate teaching use.
  • Local & Reliable: 100% on-device processing; no internet or account required.

Content Lab

Born To Speak English Lab

Where software meets practice. I built the Born To Speak Lab as a content companion to my apps — a space for role-play scripts, board-game prompts, and real-world practice to help you move from "learning" to "speaking" with confidence.

Integrated with Phonetic Formatter to bridge the gap between accurate IPA symbols and natural spoken English. It's a complete loop: from clear tools to fluent conversations.
