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

**Core Strengths:**
- Standardized calculation library for spindle speed and feed rates

**Growth Levers:**
- Localized decimal support would resolve the primary user frustration


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

The outlook for Turning Calculator Pro has shifted from stable to declining, driven by the realization that the 78-day maintenance gap and unresolved decimal input failures are actively eroding professional trust.

**Overall trend**: Declining
**Compared at**: 2026-08-06

### High-impact changes
- **[Declined] Outlook Trend** (positioning)
- **[Shifted] Contrarian Take** (positioning)

### Medium-impact changes
- **[Added] Competitive Vulnerability** (swot)

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

- Ships bug fixes at 11-week cadence.
- No feature expansion in 3 months.

<!-- /section:momentum -->

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

Turning Calculator Pro is an utilities app that is free with in-app purchases.
It holds a 4/5 rating from 1 review.

<!-- speakable-start -->
> **Bottom Line:** Turning Calculator Pro provides essential shop-floor math, but the decimal input failure renders it unreliable for professional use. Fixing the input logic would unlock the tool's utility and stabilize the user base against more responsive competitors.
<!-- speakable-end -->

**Best for:** Machinists, CNC operators, and engineers requiring quick calculation tools for lathe and turning center operations.

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

- [ ] [INVEST] Ship decimal separator support because it is the top user complaint → restore core utility
<!-- /section:pm-actions -->

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

The manufacturing utility market is consolidating around tools that offer high-precision, localized inputs. Turning Calculator Pro's current maintenance posture and input limitations leave it exposed to more agile competitors, which will likely lead to further user churn in the next quarter.

- 🔴 The 78-day update gap without feature expansion suggests the tool is in maintenance mode, which erodes professional trust.
- 🔴 The decimal input failure prevents accurate calculations, which directly contradicts the app's core value proposition of precision.
