### 2/5 — Мда уж.

*2024-11-29*

Перестало работать.

«Отсутствует интернет соединение»

Только у меня. У собеседников работает.

### 3/5 — 经常连不上网

*2023-02-13, version 2.27*

使用不稳定，经常连不上网！明明网络是正常的，可是就无法连接服务器！激活账户有时会无法激活，或者可以激活但是花的时间太长了！激活后收不到信息！无法打电话与视频，这个很遗憾！希望改进。打电话与视频可以接通，但是一接通就自动挂断！有些时候不够稳定，会闪退。

### 4/5 — Всё норм

*2022-03-09, version 2.25*

Скажите пожалуйста как можно изменить данные аккаунта и как при необходимости его можно деактивировать?

### 3/5 — writing problem

*2019-09-13, version 2.8*

From last update is a problem eith a writing cut the last word of phrase.

### 2/5 — Too much bugs

*2019-09-08, version 2.7*

- the messages sent to somebody who is not online at that moment are not always delivered. They appear to be sent but they never arrive on the other side or if they arrive, with delay or in the wrong order, which leads to confusion.
- the ticking bombs for the disappearing messages give the app a childish touch. Imagine also a bomb near a message that cannot be sent staying there forever if not deleted manually.
- the background is customizable but ii is not possible the choose one simple color.

### 3/5 — Вы серьёзно?

*2019-03-21, version 2.4*

Исправления для андроид в аппсторе?

### 1/5 — THIS IS HORRIBLE APP I HATE IT

*2025-02-17, version 2.30*

Ok so I got this app with someone I know to call and text on it until we were going in the app it said “No iNtErNeT cOnNeCtIoNs”

### 1/5 — Don’t get this app

*2025-01-16, version 2.30*

It doesn’t let u in

### 1/5 — Horrible security

*2023-01-22, version 2.27*

Horrible security. App doesn’t want to transfer over with the same account. Horrible instructions on export and import which doesn’t work at all.

### 1/5 — Support

*2020-09-06, version 2.1.5*

Soll man kaufen, dann kein Support

### 1/5 — Can’t create account.

*2019-08-01, version 2.7*

Installed it on my iPhone X iOS 12.4
Tried to create an account, there is a pop up window sitting on top of the window where you need to put your password in. Then click “done” because there is no other way to remove that window that obscures the password field. But after clicking “done” the whole program freezes. No way to go to the “confirm” password field. Big disappointment!

### 1/5 — DO NOT BOTHER DOWNLOADING

*2019-04-07, version 2.4*

This is a paid service which starts after a “free trial”. Rubbish app so will be deleting it now as why waste my money when I can chat for free and much better elsewhere!

### 1/5 — Дебильное приложение .

*2019-03-19, version 2.3*

Вводишь цифры для регистрации он пишет не верный код . Дебилы .

### 1/5 — Обман

*2019-03-15*

Я оплатила программу на год, вчера буквально через неделю после оплаты она снова стала требовать оплату.  Я решила ее переустановить , стал запрашивать штирхгод которого у меня нет , стала пытаться создать новый постоянно пишут что неправильно ввожу код пароль хотя все ввожу верно.  Что это за жесть ?

**Developer response:** Уважаемый пользователь, 

Мы приносим искренние извинения за доставленные неудобства связанные с недавними техническими работы в сети Крипвайзер.  
Просим Вас обновить приложения до версии 2.4 и восстановить с QR кода. 
После этого ваша подписка будет восстановлена автоматический.

### 1/5 — Can’t set up

*2019-03-12, version 2.3*

When creating an account it asks for a ‘captcha’ to prove I’m not a bot. Unfortunately it won’t accept the number I type. I’ve tried 30 or more different sets of numbers, which are most certainly correct, without any success. Please fix it so I can use the app and also update my review and rating.

### 1/5 — Instável

*2019-02-22*

O aplicativo é muito instável e não funciona. É difícil de vincular contatos e abrir chats. Algumas funções não respondem, parece até que o app ainda está em desenvolvimento. Muito ruim.

### 5/5 — 💔

*2025-08-17, version 2.30*

PLEASE RETURN IT🙁

### 5/5 — E una bella promesa ora che va via wicker

*2022-12-09, version 2.27*

ne vaëe la pena e un po lenta le notifiche sono a volte in ritardo ma comunque e una bella alternativa li diamo fiduccia se migliorano magare anche con alcun versione PRO a pagamento

### 5/5 — Зачем тут блохчейн

*2020-04-17*

А зачем тут вообще нужен блохчейн? Какую он даёт защиту? Связь же по нему не идёт. Просто логины на блокчейне и все.

**Developer response:** Блокчейн необходим для защиты и передачи ваших ключей шифрования, без которых ни одна криптографическая модель не имеет смысла по причине уязвимости атаки ("Человека-по-Середине"). Крипвайзер реализует DPKI модель обмена ключами шифрования и представляет технологию Автоматического Шифрования для максимальной безопасности и защщиты данных.

### 5/5 — Best Secure Messenger

*2020-04-10, version 2.12*

In my opinion the best and most secure messenger available. Unfortunately, it is not free, but a price I’m willing to pay for my privacy!

### 5/5 — So far impressed

*2019-09-27, version 2.9*

I downloaded this app and so far I’m impressed. 
Pros - blockchain verified
ECC (Which I’m guessing is better than RSA 4096 which is tech standard) 
I like the ephemeral timer, the ability to hide, lock chats with separate passwords
Block/hinder copying and forwarding of messages
Alerted if SS is taken. 
Smooth interface

Now the cons and this is just my personal preference and in no way affects the app. 

I would prefer a dark mode and the ability to add my own screen saver. 
Instead of being alerted about the SS, I would prefer it to be blocked completely but I’m guessing that’s an iOS setback. (👍🏿👍🏿 Steve) 
Smooth interface but maybe the subscription service could show more info of the blockchain nodes /servers connected? 

Finally the price ... now at first I was hesitant about the fact you have to pay when certain market apps offer e2e however upon researching I’d prefer to pay a small fee to make sure my data isn’t sold, rented, traded or left out on the “desk” for prying eyes to “stumble” across. Plus e2e has flaws which I’m guessing makes it liable to defeat. So the fact that it’s paid should be in the Pros.

I did read the privacy policy (yep I’m boring I know) however I’m curious about the developer(s) regulations on sharing with backdoor seeking governmental acronymic 3rd parties... 😉 😉 nudge nudge 

Seriously however a very very well rounded decent app so far and will keep using it.

P.S - the geo location is very accurate and secured. Disable if you are prone to stop off for “dinner” before going home to eat. 🤣

### 5/5 — Great Messanger

*2019-05-27, version 2.6*

Crypviser Secure Messanger is a great way to securely communicate. The be honest, it’s still in the beginning stages but the app is already working great. Looking at the road map, there’s a lot more cool things to come. I downloaded it, like it and am convinced that it’ll be even better in the future. Definitely 5 stars, nothing negative on my side.

### 5/5 — SUPER APP!!

*2019-05-26, version 2.6*

Die App steht bei mir auf erster Stelle, es herrscht sehr großes Datenschutz und an sich auch super!

### 5/5 — Отличное приложение и замечательная идея

*2019-04-11*

Блокчейн это бомба!!!!  Любые приложения на блокчейне, которые делаются сейчас, выстрелят однозначно!

### 5/5 — На самом деле безопасное приложение

*2019-03-21*

Отличное приложение! Уровень конфиденциальности и практичности разных фишек, как отслеживание скриншотов чатов, запрет пересылок и копирование чатов зашкаливает! Каждое обновление - новые фишки, это реально круто!

### 5/5 — Crypviser

*2019-01-29, version 2.1*

Очень удобный мессенджер, а главное безопасный!
