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

Flaska occupies a narrow niche in the Sports category as a free, specialized technical utility. The absence of updates for over 850 days indicates a lack of competitive pressure or commercial intent, positioning it as a legacy tool rather than an active market participant.
<!-- /section:market-position -->

- **Tiers:** Free
- **Analysis:** Flaska is distributed as a free utility with no observable in-app purchases or subscription tiers.

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

**Core Strengths:**
- Specialized calculation logic for twin-tank configurations provides utility for technical divers

**Growth Levers:**
- Integration of a digital dive log could capture the broader recreational market


<!-- /section:swot -->

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

<!-- section:momentum -->
## App Momentum (Zombie) {#momentum}

- No updates for 856 days.
- Maintenance-mode status confirmed.

> **Cadence:** 1 total versions · 0 majors in last 6 months · 856 days since last update

<!-- /section:momentum -->

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

Flaska is a sports app that is completely free.

<!-- speakable-start -->
> **Bottom Line:** Flaska serves as a legacy utility that lacks the update cadence required to remain relevant in the technical diving space. Sunset the app to avoid future support liabilities, as the current maintenance-mode status offers no path to growth or retention.
<!-- speakable-end -->

**Best for:** Technical scuba divers requiring precise gas management and tank volume calculations.

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

- [ ] [SUNSET] Sunset the app because the two-year development gap indicates no intent to maintain compatibility → eliminate support costs
<!-- /section:pm-actions -->

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

The technical diving utility market is shifting toward integrated, cloud-synced platforms that combine gas management with digital logbooks. Flaska's static, offline-only model is increasingly isolated, and the lack of updates signals that the developer has abandoned the product, making it a high-risk tool for safety-critical dive planning.

- 🔴 The 856-day update gap indicates a total lack of active development, which will eventually lead to OS incompatibility and user churn.
