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

**Core Strengths:**
- Apple Pencil support enables tactile schematic editing on iPad
- Built-in simulation engine provides real-time voltage analysis

**Growth Levers:**
- Expanding component libraries could attract professional engineering segments


<!-- /section:swot -->
## Recent Changes (v2 → v3) {#recent-changes}

Circuit Design maintains a static feature set and pricing model, with the primary change being a more critical evaluation of its competitive position against lower-cost, more active rivals.

**Overall trend**: Stable
**Compared at**: 2026-09-10

### Medium-impact changes
- **[Added] Competitive Pricing Benchmark** (swot)
- **[Shifted] Outlook Urgency** (positioning)

<!-- section:whats-new -->
## What's New

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

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

- Ships maintenance-only bug fix releases.
- Last major release over 6 months ago.

> **Cadence:** 1 total versions · 0 majors in last 6 months · 21 days since last update

<!-- /section:momentum -->

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

Circuit Design is an education app.

<!-- speakable-start -->
> **Bottom Line:** Circuit Design provides a functional simulation engine for mobile users, but the current maintenance-mode cadence leaves the product vulnerable to more active rivals. Prioritizing a feature-led update cycle would secure the user base against lower-cost alternatives.
<!-- speakable-end -->

**Best for:** Students, engineers, makers, and Arduino enthusiasts seeking a portable electronics lab for schematic design and simulation.

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

- [ ] [PIVOT] Ship a feature-led update because the current maintenance-only cadence risks stagnation → increase retention
<!-- /section:pm-actions -->

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

The mobile electronics simulation market is consolidating around tools that offer frequent library updates and community-sharing features. Circuit Design remains stable but exposed: without a shift to a feature-led cadence, the current subscription model will struggle to retain power users against more active competitors.

- ⚪ The latest release (v1.1) focuses on stability, indicating a maintenance-only posture that avoids feature expansion.
