Ratings and reviews

I used to use this constantly, but everytime I download it again, the 'Countries' and 'compare' categories are premium, they weren't before. I understand your grubby hands need more money to keep the sight up but making it harder for the users to find Naval craft from specific countries when they could look them up by a simple search and the tap of a Wikipedia link would make your team lose views for your app, then you wouldn't get much money anymore, and you would become a forgotten memory.

Please take away the subscription for info graphics, i payed for it i i feel that it is not worth it at all, you are paying a hundred dollar just for a few lines of imformation and a picture. I actually wanted a refund. However i am just going to let it off this time, please remove that subscription, you can earn in alot of ways, but this way is just not right.

Very outdated information, many ships that are not in service but already entered water are not included, and even more ships that are in active service are not included or wrongly placed. Very few pictures on ships as well. All you have are simple stats of the ship which can be easily found on Wikipedia. Good idea, poorly executed.
