Life in weeks · 52 weeks per year

Poster-like planning for seasons, milestones, and a finite number of weeks.

A poster-like life-in-weeks planner that turns finite time into something editable and easier to act on. Reflective rather than productivity-first, with its own editorial voice.

  • Maps life in weeks, seasons, and milestones.
  • Keeps planning data in the browser and supports export workflows.
  • Published as a standalone web app on its own subdomain.

Guided breathing, external sensors, and local-first HRV sessions.

A precision-oriented Android HRV biofeedback app for resonance breathing training. More technical and sensor-driven than a generic breathing timer, with local-first data handling and a dedicated Google Play release.

  • Built for Android with external heart rate monitor support.
  • Uses local-first data handling instead of cloud-first storage.
  • Published on Google Play, with its own landing page, setup guide, and sensor-first workflow.

Healthspan / range explorer

Wearable-friendly inputs, uncertainty bands, and a time-scrubbable future healthspan view.

A healthspan and physical-capacity explorer built around noisy, real-world inputs. It turns fitness, strength, body composition, and wearable signals into future-facing lower, base, and upper trajectories instead of a single fake-precise answer.

  • Combines cardio and strength on an interactive timeline with age-based risk signals.
  • Works with consumer-friendly inputs like VO2 estimates, body composition, grip, deadlift, or dead-hang fallback.
  • Framed as a practical wellness outlook with uncertainty bands instead of a clinical-style prediction.

Ultra HDR from SOOC JPEGs

Keep the film simulation. Add real HDR highlight data from the RAW.

A macOS Ultra HDR JPEG app for Fujifilm X100 and Ricoh GR shooters who want to preserve their SOOC film simulation look while adding real HDR highlight data from the RAW file.

  • Preserves the camera-rendered JPEG as the displayed image — the RAW is only used for HDR gain map data.
  • Outputs standard Ultra HDR JPEGs with normal SDR fallback for non-HDR displays.
  • Built for photographers who shoot RAW+JPEG and care about film simulation rendering.
