From a virtual ‘walkie talkie’ to offline maps: the most downloaded ‘apps’ in the Ukraine war | Technology

As Ukraine calls for an end to Russian bombing of civilians, the population is looking for ways to protect itself. A apps that sends alerts to the mobile before any air attack in a certain area has been this Monday the most downloaded from the App Store in the country, according to the research firm Apptopia. Its creators claim that it serves to “prevent injuries and avoid absolutely unnecessary deaths in situations in which people cannot hear the sirens.”

The population of the former Soviet republic also uses encrypted messaging services and apps to view offline maps. “Applications that are rising to the top of the charts in Ukraine are walkie-talkies, VoIP (to make voice calls over the Internet), offline browsing, VPN and radio communications” , Apptopia spokesperson tweeted after the Russian invasion, adam blacker. Some of these alternatives allow communication offline through radio signals or through bluetooth. “These are applications that we normally see in fashion during natural disasters like hurricanes and earthquakes,” Blacker said.

The apps of communications lead the ranking of both the Play Store as of the app store, according to data from Apptopia. The first places are occupied by some like Signal, Telegram, Zello Walkie Talkies or Bridgefy. Signal excels at end-to-end encryption to keep chats private. This means that only users can read the messages that are sent to each other and no one can listen to their calls. “Unlike Telegram, whose end-to-end encryption only works on the famous two-user secret chats, Signal also encrypts group chats and calls end-to-end,” explain it Kaspersky cybersecurity company.

Although Telegram does not offer end-to-end encryption by default, it does allow users to manually enable an encrypted secret chats feature. Simply open a contact’s profile, click on the “more” button and choose the option to start a secret chat. Doing so opens a conversation where you can choose to delete messages every so often — from a second to a week. If one of the users takes a screenshot, a notice appears in the chat. Although the app allows you to have multiple secret conversations with the same person, it does not offer this feature for group chats.

Some Ukrainians use Zello Walkie Talkie, a apps what allows you to maintain encrypted private conversations end to end. To talk to other users, all you have to do is press and hold a button on the screen. Of course, Internet is required. This is precisely where the strong point of Bridgefy lies, an application that allows you to send encrypted messages without the Internet up to 100 meters away thanks to the bluetooth.

Its creators assure that it is an “ideal alternative to use on trips, natural disasters, rural communities, festivals or stadiums.” It has also been used during some protests in countries such as Hong Kong, India, Zimbabwe, and the United States. But the app has not been without its critics in recent years. in 2020 a team of researchers from the University of London criticized its use in protests because, in theory, it allowed users to be tracked and their messages to be read by others.

More terminals are on the way”, replied the businessman that same day. The goal is that these gadgets allow Ukrainians to stay connected before the cuts of Internet that already devastate the country.
