<!-- section:executive-snapshot -->
## Executive Snapshot
**What it is:** My SISU is a white-label booking and management app for fitness studios and sports academies on iOS.
**Why users hire it:** Studio owners hire the app to provide a branded booking experience for members, though it lacks the automated intelligence required to reduce administrative overhead.
<!-- /section:executive-snapshot -->

<!-- section:features -->
## App DNA (Features & Intent)
- **[Standard] Mobile Booking:** In-app scheduling for fitness classes and personal training sessions
  * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior.

<!-- /section:features -->

<!-- section:market-position -->
## Market Position {#market-position}

My SISU operates as a niche B2B tool for studio management, lacking the public chart presence of marketplace-integrated competitors like fitli. The absence of user ratings suggests the app functions primarily as a private utility for existing studio members rather than a discovery platform.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Subscription
- **Tiers:** Free app download for end-users, B2B subscription model for fitness studios
- **Analysis:** B2B SaaS model targeting fitness studios and gym chains with tiered management features.

<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- Branded app interface allows studios to maintain visual identity

**Critical Frictions:**
- Zero rating count on iOS limits social proof
- No native HealthKit integration for activity tracking

**Growth Levers:**
- Wearable integration would reduce utility gap against municipal apps

**Market Threats:**
- AI-driven front desk automation in rival platforms reduces manual management demand

<!-- /section:swot -->
## Recent Changes (v3 → v4) {#recent-changes}

The platform pivoted its development priority from financial reporting to HealthKit integration and updated its competitive landscape to focus on specialized studio management rivals.

**Overall trend**: Stable
**Compared at**: 2026-05-25

### High-impact changes
- **[Shifted] Development Roadmap Pivot** (features) — PM action items shifted priority from financial reporting to HealthKit integration to address feature parity gaps.
- **[Shifted] Competitive Landscape Refresh** (positioning) — Replaced general fitness trackers with specialized studio management competitors including WellnessLiving Achieve, Walla, and fitli.

### Medium-impact changes
- **[Added] New Competitive Threats** (swot) — Added AI-driven front desk automation as a threat and lack of HealthKit integration as a weakness.
- **[Added] Expanded Feature Gap Tracking** (features) — Added AI-driven front desk automation and native HealthKit integration to the tracked feature gaps list.

<!-- section:whats-new -->

<!-- /section:momentum -->

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

My SISU is an established health & fitness app that is available.

<!-- speakable-start -->
> **Bottom Line:** My SISU provides a functional booking utility for studios, but its lack of consumer-facing features and AI automation makes it vulnerable to churn, so the PM should prioritize HealthKit integration to defend the user experience against more feature-rich competitors.
<!-- speakable-end -->

**Best for:** Fitness studio owners, gym chains, and sports academies requiring management software, and their end-user clients.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [INVEST] [MEDIUM IMPACT] Integrate HealthKit because it is a standard expectation for fitness apps → increase daily active usage — *Competitor RecFW provides native HealthKit integration, highlighting a feature parity gap.* _(trade-off: deprioritize Pause the financial reporting dashboard update — HealthKit integration has higher impact on end-user retention.)_
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors

- AI-driven front desk automation (available in WellnessLiving Achieve)
- Native HealthKit integration (available in RecFW)
- Integrated payment processing in booking flow (available in fitli)
<!-- /section:feature-gaps -->

<!-- section:outlook -->
### Outlook: Stable

The boutique fitness management market is consolidating around platforms that offer AI-driven administrative automation. My SISU remains exposed as long as it functions only as a booking shell, so the platform must integrate health-data tracking to remain relevant to end-users.

- ⚪ The latest release focused on stability, indicating the product is currently in maintenance mode rather than active expansion.
