Health & Wellness

Privacy-first health software — habit engines, patient portals, and wellness platforms.

Health and wellness software demands two things above all others: privacy and protocol. We build habit tracking systems, daily protocol engines, patient portals, subscription wellness products, and encrypted journaling tools — all with proper data handling and HIPAA-adjacent security patterns.

Problems in this industry

  • Generic habit apps don't support clinical or structured protocols
  • Patient/member data needs encryption and strict access controls
  • Daily protocol delivery (emails, reminders) is fragmented
  • Streak and progress tracking needs server-side integrity
  • Subscription billing for wellness products is complex
  • Analytics on behavior patterns require custom dashboards

What we build

Daily protocol engine

Timed events (morning, midday, evening), cron-triggered email delivery, guided prompts — the core of any structured wellness product. Proven in HopeRising.

Streak + progress tracking

Server-side streak calculation (not client — prevents manipulation). Progress dashboards: weekly charts, milestone tracking, longest streak.

Encrypted journaling

Client-side AES-256 encryption before storage. Server never sees plaintext. Key derived from user password via PBKDF2.

Member/patient portal

Authenticated portal with private progress data, program steps, analytics, and coach/practitioner access with role-gated views.

Subscription wellness SaaS

Free tier (awareness tools, starter program) → Pro tier (full program, analytics, reports). Stripe subscriptions, automatic renewals.

Behavior analytics dashboard

Trigger pattern analysis, time-of-day charts, weekly trend reports — surface patterns that help users and practitioners make decisions.

Example features

  • Recovery / sobriety app (HopeRising pattern)
  • Therapy practice patient portal
  • Corporate wellness platform (team challenges, company dashboards)
  • Fitness coaching app (program delivery, check-ins, progress)
  • Nutrition tracking SaaS (meal logs, macro analytics, coach portal)
