User reviews

Great app, not perfect

This is a great app and I use it daily. I am a very visual person and it is a great help in figuring cable paths and gear counts.

The one thing I wish it had was the ability to add multiple rows of half tiles to a wall instead of one. Seems silly maybe, but a half tile is not just half the weight or half the power of a full tile, and it would be great to have better tools to calculate when having to use two rows of halfs to make a single row worth of fulls because of inventory.

Response from developer

Hi, thank you for your feedback! We have just released a new version with many improvements and new functionality which I think you'll like! We have noted your feedback and will look at implementing this as a feature. One technical side note, half panels also tend to have a slightly different structural limit, making the maximum hanging limit harder to calculate for a mixed setup. But that is of course only more reason to implement this. Thank you!
