Build: Products & Hobbies

WHAT I'VE BUILT.

Everything here is independent work, mostly health and fitness. Two apps are on the App Store, one is a live product, one is a concept, and the rest are hobby projects that fill a gap and are not for sale.

Platforms Visual
PulseAware
Speaking pace, fillers, stress

PulseAware

App Store

A mobile app for real-time voice, biometric, and session-based feedback on how you come across while you speak. Free to download, with a one-time $4.99 Pro unlock and no subscription.

Health and wellness at the core of Build: heart rate, voice, and stress signals turned into feedback you can use, all on-device.

HeadPause
Vertigo & Balance Practice

HeadPause

App Store

GentleReturn
Meditation & Attention

GentleReturn

Hobby, Coming Soon

Wordless meditation companion that notices when attention drifts from the breath and brings you back with a touch, never a voice. Free runs fully on iPhone alone, breath and motion detection with the complete sound library. Pro adds AirPods and Apple Watch sensing, longer sessions, and history. Entirely on-device, one-time purchase planned, no subscription.

The next health and wellness app in Build, extending the on-device sensing behind PulseAware and HeadPause into meditation and attention.

SentientOps
R&D initiative

SentientOps

Hobby

GMX3C's long-range research into agentic operations: operator workflows and control systems that depend on a level of machine reasoning, autonomy, and operational trust the technology cannot deliver yet. Every frontier release moves that ceiling higher. We're building toward the first version that clears it.

A hobby in long-range research: what operations could look like once AI can be trusted with real authority. Not for sale.
