Machinist Tap Drill Chart
By Signet
Machinist Tap Drill Chart is a specialized utility for machinists that computes thread diameters, drill sizes, and thread percentages on iOS.
The App DNA
What makes this app unique?
The app removes the cognitive and time cost of manual formula lookups, providing a reliable reference that functions without internet access in machine shops.
For Machinists and shop-floor personnel requiring precise, offline-accessible engineering data.
What does it look like?
Key features
Computes thread diameter, drill size, and percent of thread for UNC, UNF, metric, and NPT standards.
Cross-references drill indices to find the closest match for a specific thread percentage.
Computes clearance holes for various fits and STI holes for wire thread inserts.
Calculates all values locally using internal tables without network dependency.
How much does it cost?
The freemium model anchors on a $5.99 lifetime purchase, using advanced hole types and custom tolerances as the primary conversion gate.
Velocity
Maintenance developmentopaqueShow more...
The app maintains a maintenance-level cadence, with only one release recorded in the analyzed window. Having shipped 33 days ago, the development cycle shows no signs of active feature expansion or live operations. The lack of descriptive release notes suggests a focus on minor stability or maintenance rather than new content. Development remains stagnant with no clear roadmap for future updates.

Key takeaways for Machinist Tap Drill Chart
Where is it heading?
The shop-floor utility market is consolidating around tools that offer high-precision, offline-reliable data. Machinist Tap Drill Chart remains advantaged by its offline-first architecture, but the lack of recent feature investment risks ceding market share to rivals that can iterate faster on professional-grade engineering requirements.
- The maintenance-only release cadence suggests a stable, feature-complete product that prioritizes reliability over rapid expansion.
- The lack of new feature development over the last 33 days leaves the app exposed to rivals with more active update schedules.
The SWOT
- Offline-first architecture ensures utility in signal-blocked shop environments.
- Localized pricing could capture users in regions where the $5.99 entry point is high.
Next best moves
Audit the Pro-tier conversion funnel because the current $1.99/week subscription is high for a utility app → increase lifetime conversion

Read the full takeBottom line
Machinist Tap Drill Chart's offline-first design provides a defensible utility, but the current subscription pricing creates friction that limits the conversion funnel. Shifting focus to lifetime-purchase incentives would better align with the professional user's preference for one-time tools.
