## What is Wispr?

Given today’s challenge of keeping one’s privacy private, Wispr is the present and future of secured communication. Each high-fidelity message, audio/video call or file transfer is fully private with no one, not even us, being able to interfere. 

FULLY PROTECTED : State-of-the-art technology ensures secured messages and file transfers to and from anyone at any time. You don’t have to worry about needing special features as having all things private and secured is normality for Wispr. 

BY NEW ENCRYPTION TECHNOLOGY: Having each and every element on the app (messages, audio and video calls, file transfers) encrypted is brought to you by VOBP (Voice Over Blockchain Protocol), which makes your communication bullet proof. 

FOR FREE : Privacy should not be perceived as a preference, but as a given and so Wispr should not be a choice, but a normality. 

WITH NO FURTHER EFFORT : Wispr is available for everyone through the simple use of their phone number and address book or through using Matrix ID that is one can directly access owners of Impulse K1, a phone taking encryption to a whole new level.  However, Wispr’s future has much to hold in terms of taking privacy to a whole new level.

YET BEST QUALITY : Slow networks are not a show stopper for Wispr, which is optimized to perform equally successful in all kinds of environments all over the world. Top that with a user friendly, very intuitive design and low latency and you get your choice of privacy providing app.

### 1/5 — Doesn’t work

*2024-02-03, version 1.1.5*

The sign up for the app is broken. Keeps asking to complete captcha without moving forward. 👎👎👎

### 5/5 — Foarte ok

*2024-01-08, version 1.1.5*

Un program super

### 1/5 — This application is probably just deceptive advertising

*2024-01-07, version 1.1.5*

You launched the application on the market almost three years ago and you still haven't performed an external audit of it.  I think that you are deceiving users and that the application not only does not allow you to make an account anonymously, but there is also no guarantee that it really protects users' conversations.
