## Review summary

Overall the app is praised for quick, high-level structure understanding and usefulness, but recurring issues include login failures, data accuracy and dimensioning gaps, incomplete regional standards, limited catalog with no visual aids, and stability problems, suggesting a promising tool hampered by reliability and data concerns.

### Pros

- Excellent for a quick, high-level understanding of structures (great for architects).
- Generally nice and useful app with positive feedback from multiple users.
- Described as an awesome tool and has been loved by users.
- Users also report the app is pleasant to use and has potential.

### Cons

- Login/access problems: Google login not working and blocked sign-in flow.
- Data and dimensioning issues: incorrect weights/parameters, zero weight readings, and lack of dimensioned shapes.
- Limited catalog and missing visuals: only a subset of sections with no dimensioned diagrams or pictures.
- Inconsistent standards and naming across regions: US wide-flange naming, missing Turkish/Indian/Australian standards.
- Stability problems: app freezes and crashes during use.
