This is a great app! Since sincerely, it taught me so much about cryptography and as a programmer, I can now just use this instead of making the encrypters/decrypters myself, but, I did find a bug in the navajo language translator and it was "Error; java.lang.NullPointerException: Attempt to get length of null array"(I use C not java so I don't have a opinion on why this doesn't work), but other than that, this app is great!

Overall, a very good and well detailed app. My only problem is that once I leave a particular cipher to pick another from the main list, an add comes up that has no "x" to get rid of/skip it. It's written in either Chinese or Japanese and it's very frustrating as I have to close the app and reopen it every time I wish to change cipher. Once that's fixed, a well deserved 5 stars are in order. 🙌

Weird. I use Googles ad sdk to show ads. I see if theres updates since this may be a bug.

I absolutely love this app. it's one of the most fascinating things I've ever gotten to play around with, and that description is the exactation of what I understand about the content that offers. which makes me super happy cuz frankly I like to be and feel stupid. and still try to learn smart stuff.
