What does it look like?
Key features
Calculates distance, area, and volume on 3D planes using the device camera.
Multi-touch interface for measuring small objects against the display.
How much does it cost?
The app relies on ad-inventory generated by high-frequency utility usage rather than a subscription or premium tier.
Velocity
Maintenance developmentperformanceShow more...
The app currently operates at a maintenance cadence, with only one release recorded in the last 111 days.

Competitive landscape for Ruler •
How's the Utilities market?
Ruler • operates in the crowded Utilities category with a 4.2-star rating across 398 total ratings. The lack of a paid tier suggests a volume-based strategy, but the 112-day update cadence and persistent unit-switching bugs limit its ability to compete with more stable, frequently updated alternatives.

Key takeaways for Ruler •
Where is it heading?
The utility market is consolidating around apps that offer high-precision AR tools with low friction, and Ruler • is currently losing ground due to technical regressions. The lack of active feature investment means the app is increasingly exposed to more stable competitors, so the team must shift to a high-frequency fix cycle to stabilize the user base.
- Persistent unit-switching bugs in the latest release erode user trust, which compounds the rating drag already visible on the platform.
- The 112-day update cadence without feature expansion suggests the app is in maintenance mode, limiting its ability to compete with active rivals.
The SWOT
- AR measurement suite functions as a differentiator for spatial estimation tasks
- Implementing a guided tutorial would reduce the primary barrier to entry for the AR suite
Next best moves
Rebuild unit-switching logic because it is a top-cited usability failure → reduce churn

The app's reliance on ad-inventory for a utility tool is a strategic vulnerability…
Read the full takeSince the last report: The app remains in a maintenance-only state with no new features or pricing changes, though the competitive analysis now more clearly identifies the risks of its ad-supported model.
Bottom line
Ruler • provides a broad suite of AR tools, but core measurement inaccuracies and broken unit-switching erode user trust, so the team must prioritize stability fixes over new features to prevent further churn.
