### 3/5 — Missing basic features

*2024-11-02, version 1.4*

App missing basic features. overall good app, however if there was an option to build : Wall layers , another one be called Roof layers ,another ground layers. That way will make more sense 
A useful option would be to see the layers in a 3d like image
Another suggestion is that ,allowing the production of a report that shows all the above suggestion on one paper
Cutdown to do the developer , please carry on developing the app

### 3/5 — M Biernat

*2021-12-15, version 1.3*

I am an architect in England. This would be a seriously useful app, but the values for air in cavities where convection is a dominant feature and wall ties are required are very wrong. The developer needs to consult British and international standards for this app to be useful for professionals.

### 4/5 — Good Dew point app

*2021-05-01*

It does what is supposed to do, it only needs two things; 1.) Save wall builds styles 2.) export capabilities, jpeg, pdf, and/or dwg 
Hope you can make those requests soon to get you to the five stars

**Developer response:** Thank you for your feedback. This functionality will be added in future updates.

### 4/5 — Quality Support Manger

Would be helpful to have material properties explained and in imperial units when creating new materials.  Graphics are very good.  How can you save typical wall constructions for future reference.  Make adding a material in the wall assembly possible. Seem to only be able to delete.  Very helpful as a quick check on condensation potential.

**Developer response:** Thanks for your feedback. An explanation of material properties will be added in a future update. To add material to the structure, click the "edit" button and drag the selected material to the desired position.

### 5/5 — Good app would like to collaborate

*2023-05-06, version 1.3*

I’ve been using this app on site surveys to compile quick u-value calculations based on what constructions are actually on site. 
I would be interested in rebranding/reselling this app to other surveying companies in my sector, but don’t actually seem to be getting any responses from the developer to my sent emails?

### 5/5 — Works great but missing basic features

*2021-06-16, version 1.3*

Good quick checking tool for facade build ups, but it appears to be missing very basic functionality, such as saving and re-loading your proposed wall assemblies. Localised weather data for a 12 months period would also assist with determining interstitial condensation risk for the full spectrum of climatic conditions. Hopefully, the app will continue to be developed to include additional functionality and features.
