You are not buying the next best thing to a Haynes manual! For a Peugeot 3008, I actually needed to download 12GB of manuals for many Peugeot models together with a virtual machine to run the interactive manual in Windows XP. It says 'SERVICE BOX Documentation Backup' at the top so I think it is an offline backup version of Peugeot Citroen's 'Service Box'. I reckon that a geek could make this work on a tablet but normal people can only use it on a PC or laptop. At my request, I promptly received a DropBox link to the 'PDF' version to use on my tablet at the vehicle. This was not a PDF document as such; just 3051 images (pages) captured from the app and saved in a PDF with no index or search facility; even the bookmarks could not be searched. The interactive manual is very thorough but painful to follow. For example, engine tasks may require the removal of the 'protective panel' under the engine compartment but it is not cross referenced and you need manually to search through the bodywork section to find it where it has changed its name to protective engine shield (which also does not show up in the search facility.) In sum: maybe great for professionals or enthusiasts who use it regularly but not for the casual DIYer who just wants to change the windscreen washer pump.
