The MVP Sprint

With the architecture pivot complete and security hardening done, Sessions 4-5 focused on building out all the core features. The goal: a fully functional application that users could actually use.

Backend Services

Each service follows the same pattern: encrypted storage, user isolation, and comprehensive CRUD operations.

Pillars Service

User-defined life categories for tracking

  • Create custom pillars (Family, Health, etc.)
  • Set targets and current values
  • Color coding and icons
Daily Entries Service

Core journaling functionality

  • One entry per day per user
  • Encrypted content storage
  • Pillar linkage
Feels Service

Emotional signal intelligence

  • Morning Pulse (mental state, strongest emotion)
  • EOD Reflection (energy, pressure/purpose)
  • What you're avoiding
Weekly Recaps Service

Weekly synthesis and patterns

  • Pillar score aggregation
  • Pattern identification
  • Course corrections

The Daily Flow

TimOS is designed around a specific daily workflow:

AM
Morning Pulse

Mental state check, strongest emotion, what you're avoiding, morning habits.

Day
Daily Entry

Quick notes, pillar-linked entries, progress tracking.

PM
EOD Reflection

What gave/drained energy, pressure or purpose, honest note to yourself.

Weekly
Weekly Recap

Pillar scores, pattern identification, course corrections.
