GDTPro is a productivity toolkit for engineers and inspectors, providing GD&T reference and calculation tools on iOS.
The App DNA
What makes this app unique?
Engineers require rapid, offline access to complex geometric standards during manufacturing inspections where connectivity is often restricted.
For Engineers, students, and inspectors in aerospace, automotive, and medical device manufacturing.
What does it look like?
Key features
Constructs and validates feature control frames with real-time error detection, establishing core utility.
Extracts feature control frames from engineering drawings, gating high-value productivity behind the Pro tier.
Imports STEP AP242 files to extract manufacturing information, driving conversion from students to professionals.
Switches between ASME Y14.5-2018 and ISO GPS standards, providing utility for international teams.
How much does it cost?
The freemium model gates advanced engineering analysis tools behind a Pro upgrade to capture professional users.
Velocity
Dormant developmentopaqueShow more...
The app has seen no development activity for 163 days, placing it in a state of stagnation. With only a single version released since its inception, there is no evidence of ongoing maintenance or feature iteration. The lack of updates over this period suggests the project is currently inactive.

Key takeaways for GDTPro: GD&T ASME Calculator
Where is it heading?
The market for technical engineering tools is consolidating around apps that provide high-fidelity standard compliance and CAD integration. GDTPro remains advantaged by its offline-first design, but the lack of recent updates leaves the app exposed to competitors with more frequent release cadences.
- The five-month development gap suggests a maintenance-only posture, which limits the ability to respond to new standard revisions.
- The offline-first architecture provides a defensible utility for secure manufacturing environments that cloud-dependent competitors cannot easily replicate.
The SWOT
- Dual-standard compliance (ASME/ISO) enables international engineering workflows.
- Offline-first architecture ensures utility in secure, connectivity-restricted manufacturing environments.
- Step-by-step formula breakdowns for bonus tolerances reduce cognitive load for students and inspectors.
- Professional-grade CAD import (STEP AP242) creates a high-value conversion funnel for engineering students.
- Camera OCR scanning reduces manual entry friction for inspectors reviewing physical engineering drawings.
