Gronze also has a lot of 'hidden' information. For each stage of a camino, there are three tabs that contain different pieces of information. Looking at it now, the tab buttons seem fairly large and obvious at the top of each page but for a long time I didn't realise that these tabs existed.
The default tab is Albergues, which is self-explanatory -- it gives you accommodation options but doesn't give any details about the stage itself apart from a brief introduction. For several years, that's all I thought Gronze provided.
The second tab is Recorrido*, which is the guide book type part of the page, where it gives way-marking instructions and talks about the villages and landmarks etc during the stage. When we finally discovered this tab last year, it was great for our Portuguese Interior because we had no other book/app and this helped us break down each stage into manageable chunks.
Finally the Al Loro tab contains 'the most interesting things to know before starting a stage' and other curiosities. I haven't used this tab much but it seems that it would be useful in the planning period, and then Recorrido is what you would look at during a stage to know what's coming up.
* I use Gronze in Spanish and I'm not sure exactly how the machines translate Recorrido in this case (and I don't want to encourage my browser to translate) but I imagine it would be something like Route or Path.
