- Just noticed that many reviews mentioned that the price is too high. I am using Logos happily since its 4th version. I agree that the price is not always great. Many times I buy the same book on amazon several pounds cheaper and it is easier to read a book on kindle in my view - pages can be turned fast etc. But to balance the opinion here the upgrade to Logos 7 starter package is £51 and I think that's ok. Full feature Logos 7 cost £245 and the list of features is endless. I dont need them so I will not upgrade to that. What more, it is possible to buy features individually. How far should Logos go to allows people to customise their Logos' functionality. Maybe I am just missing something here but I do give 5star for the provision of the customization of every feature available.
