### 5/5 — Nearly desktop version, but on the go

*2018-04-21*

ASTME-1300, gives me calculations of loads and center of deflection.

### 1/5 — $150 annually. Wretched design

*2018-01-30*

You cannot do anything except pay $150 for an annual subscription. The design is...not good.

**Developer response:** Hi, thanks for your feedback. We'd love to hear more about any issues you have with the app. Please get in touch with us at tech@standardsdesign.com. Thanks!
