This is not good as I use it often and now suddenly it’s not working. What’s going on? ### 5/5 — Easy to use app *2020-11-20, version 1.9* Easy to use. From what I've read this type of encryption will keep most people from reading the encrypted files. Not military grade so professional analysts would be able to break the encryption. 11/20/20 Question How to use the COPY function? It generated a file which can be opened . ### 5/5 — 777 *2019-08-06* Замечательное приложение! 👍🏻 ### 1/5 — iPhone X fail *2018-05-04* It works to send txt, however, when I receive an encrypted txt, after I put in the password and hit decrypt, it kicks me out of the app!!!! ### 5/5 — Aplicativo incrível *2016-02-01, version 1.9* Muito bom esse aplicativo, principalmente como defesa em tempos de aumento de crimes nas redes sociais! ### 5/5 — Outstanding *2016-01-08* For daily routine comms you want to keep private-this is the app. Not high grade as previous reviewer states but more than adequate. My only complaint is the background color of white. Makes it difficult to differentiate text vs email. ### 5/5 — Excellent tool *2015-11-15, version 1.9* Love it ### 4/5 — Мне понравилось честно! *2015-05-20* Тупо просто удобно!работает шифрует ### 5/5 — Excellent *2015-03-03, version 1.9* A great little app with the additional advantage of pc and Mac versions. Ideal for securing personal information on Evernote etc. Ad's unintrusive (to my eyes) at base. The best app of it's type that I've tried. ## Frequently asked questions about TXTcrypt ### What does TXTcrypt do?
