WhatsApp Messenger Apps on Google Play

Visual effects also became available, adding visual filters to a user’s video feed. In December 2024, WhatsApp introduced several new video calling features, including the ability to select specific participants from a group to make a call, rather than calling all group members. In June 2024, improvements were made to voice and video calls, allowing up to 32 participants in video calls, adding audio to screen sharing, and introducing a new codec to increase call reliability. In November 2023, WhatsApp added a “voice chat” feature for groups with more than 32 members. Later in September 2018, WhatsApp introduced group audio and video call features.

  • According to the company, messages could be edited within a 15-minute window after being sent.
  • Koum then hired a friend in Los Angeles, Chris Peiffer, to develop a BlackBerry version, which arrived two months later.
  • In January 2022, an unsealed surveillance application revealed that WhatsApp started tracking seven users from China and Macau in November 2021, based on a request from US DEA investigators.
  • According to the Financial Times, WhatsApp “has done to SMS on mobile phones what Skype did to international calling on landlines”.
  • The company also announced plans to implement reactions, the ability for administrators to delete messages in groups and voice calls up to 32 participants.

It was also not available for iOS users on launch, due to limitations from Apple. The web client was not standalone, and required the user’s phone to stay on and connected to the internet. In a later update on November 30, WhatsApp added a Secret Code feature, which allows those who use locked chats to enter a unique password that hides those chats from view when unlocking the app. In October 2023 they also introduced passkey support, where a user can verify their login with on-device biometrics, rather than SMS. In July 2021, WhatsApp announced forthcoming support for end-to-end encryption for backups stored in Facebook’s cloud.

By April 22, 2014, WhatsApp had over 500 million monthly active users, 700 million photos and 100 million videos were being shared daily, and the messaging system was handling more than 10 billion messages each day. When this multi-device feature was first introduced to Android and iOS users, it could only show messages for the last three months on the Web version, because the Web version was syncing with the phone. Similar to voice messages, this feature allows users to record and send short videos directly in a chat. In May 2017, it was reported that WhatsApp users spend over 340 million minutes on video calls each day on the app. In May 2016, some WhatsApp users were reported to have been tricked into downloading a third-party application called WhatsApp Gold, which was part of a scam that infected the users’ phones with malware. Since the complete roll out of this feature, users cannot check old messages before this period on the Web version anymore.

In March 2019, WhatsApp released a guide for users who had installed unofficial modified versions of WhatsApp and warned that it may ban those using unofficial clients. In September 2022, a critical security issue in WhatsApp’s Android video call feature was reported. This is reportedly not an isolated occurrence, as federal agencies can use the Electronic Communications Privacy Act to covertly track users without submitting any probable cause or linking a user’s number to their identity. The app collected data on who the users contacted and how often, and when and how they were using the app. In January 2022, an unsealed surveillance application revealed that WhatsApp started tracking seven users from China and Macau in November 2021, based on a request from US DEA investigators.

BiP – Messenger, Video Call

Researchers and journalists called on WhatsApp’s parent company, Facebook, to adopt measures similar to those adopted in India and restrict the spread of hoaxes and fake news. In November 2020, UPI payments via WhatsApp were initially restricted to 20 million users, and to 100 million users in April 2022, and became generally available to everyone in August 2022. The application can store encrypted copies of the chat messages onto the SD card, but chat messages are also stored unencrypted in the SQLite database file “msgstore.db”. The feature has to be turned on by the user and provides the option to encrypt the backup either with a password or a 64-digit encryption key.

MAJOR UPDATE

At that point WhatsApp was adding about 25 million new users every month, or 833,000 active users per day. In September 2017, security researchers reported to The New York Times that the WhatsApp service had been completely blocked in China. In April 2017, the perpetrator of the Stockholm truck attack reportedly used WhatsApp to exchange messages with an ISIS supporter shortly before and after the incident.

User statistics

  • On December 16, 2020, a claim that WhatsApp gave Google access to private messages was included in the anti-trust case against the latter.
  • By clicking “Post Your Answer”, you agree to our terms of service and acknowledge you have read our privacy policy.
  • WhatsApp was announced to be the 3rd most downloaded mobile phone app of the decade 2010–2019.
  • This ability (named multi-device support) began testing in July 2021 and rolled out to all users in April 2023.
  • In November 2019, WhatsApp released a new privacy feature that let users decide who can add them to groups.

They link to and sync with WhatsApp actively running on a supported primary phone. Engadget called the revamped feature “WhatsApp’s version of an AIM away message” and likened it to Instagram’s and Facebook’s Notes. Prior to the update, the feature was “largely hidden within the apps menus” and difficult to find, with the reason for updating being that WhatsApp wanted the feature to be used more often. According to WhatsApp, this update was made for the incoming Christmas period for users to inform their contacts on their activities during the holidays. WhatsApp also introduced chat filters, allowing users to sort their chats by All, Unread or Groups.

In April 2024, an AI-powered “Smart Assistant” became widely available in WhatsApp, allowing users to ask it questions or have it complete tasks such as generating images. Channels were initially only available to users in Colombia and Singapore, then later Egypt, Chile, Malaysia, Morocco, Ukraine, Kenya and Peru before becoming widely available in September 2023. In April 2022, WhatsApp announced undated plans to roll out a Communities feature allowing several group chats to exist in a shared space, getting unified notifications and opening up smaller discussion groups.

Africa, Middle East, and India

On August 24, 2014, Koum announced on his Twitter account that WhatsApp had over 600 million active users worldwide. However, the company did not reveal the names of the end users, which according to research by Citizen Lab include, Saudi Arabia, Bahrain, Kazakhstan, Morocco, Mexico and the United Arab Emirates. The hack, allegedly developed by Israeli surveillance technology firm NSO Group, injected malware onto WhatsApp users’ phones via a remote-exploit bug in the app’s Voice over IP calling functions.

Data Linked to You

The army recommended that all army personnel use Threema instead, as the service is based in Switzerland. Once again, the block was lifted following an appeal, after less than 24 hours. On May 2, 2016, mobile providers in Brazil were ordered to block WhatsApp for 72 hours for the service’s second failure to cooperate with criminal court orders.

According to the company, messages could be edited within a 15-minute window after being sent. In 2022, WhatsApp added the ability for users to turn off their online status. In August 2022, WhatsApp launched an integration with JioMart, available only to users in India. The Cloud API enables businesses to integrate WhatsApp with other software, have a central WhatsApp account for multiple users and implement advanced automation. In May 2022, WhatsApp launched its Cloud API services (now known as WhatsApp Business Platform) for larger businesses requiring features beyond the WhatsApp Business App.

The ban was prompted by concerns of US authorities potentially accessing user data for such apps because of the CLOUD Act. In December 2021, the Swiss army banned the use of WhatsApp and several other non-Swiss encrypted messaging services by army personnel. On May 9, 2014, the government of Iran announced that it had proposed to block the access to WhatsApp service to Iranian residents.

In December 2019, WhatsApp announced that a new update would lock out any Apple users who had not updated to iOS 9 or higher and Samsung, Huawei, Sony and Google users who had not updated to version 4.0 by February 1, 2020. In August 2014, WhatsApp was the most popular messaging app in the world, with more than 600 million users. Providing a bundle of these free of charge to users will work like a gateway drug of sorts – users who may be able to afford data services and phones these days just don’t see the point of why they would pay for those data services. WhatsApp has increasingly drawn its innovation from competing services, such as a Telegram-inspired web version and features for groups. In May 2014, WhatsApp crossed 50 million monthly active users in India, which is also its largest country by the number of monthly active users, then 70 million in October 2014, making users in India 10% of WhatsApp’s total user base. By February 2017, WhatsApp had over 1.2 billion users globally, reaching 1.5 billion monthly active users by the end of 2017.

WhatsApp is owned by Meta, whose main social media service Facebook has been blocked in China since 2009. A message that promises to allow access to their WhatsApp friends’ conversations, or their contact lists, has become the most popular hit against anyone who uses the application in Brazil. In April 2017, nearly 300 WhatsApp groups with about 250 members each were reportedly being used to mobilize stone-pelters in Jammu and Kashmir to disrupt security forces’ operations at encounter sites.

WhatsApp’s voice codec is Opus, which uses the modified discrete cosine transform (MDCT) and linear predictive coding (LPC) chicken road app audio compression algorithms. Some devices using dual SIMs may not be compatible with WhatsApp, though there are unofficial workarounds to install the app. Similarly to WhatsApp for web, Windows, Mac, and smartwatches, the iPad is a type of linked device that connects and syncs to WhatsApp running on a smartphone.

In November 2019, WhatsApp released a new privacy feature that let users decide who can add them to groups. On April 5, 2016, WhatsApp and Open Whisper Systems announced that they had finished adding end-to-end encryption to “every form of communication” on WhatsApp, and that users could now verify each other’s keys. They expressed the concern that regular WhatsApp users still could not tell the difference between end-to-end encrypted messages and regular messages. WhatsApp uses a “store and forward” mechanism for exchanging messages between two users.

However, when early versions of WhatsApp kept crashing, Koum considered giving up and looking for a new job. Koum named the app WhatsApp to sound like “what’s up” and it was published on the Apple App Store and BlackBerry App World in May and June 2009 respectively. A month earlier, after Koum purchased an iPhone, he and Acton decided to create an app for the App Store. In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client. Privacy practices may vary based, for example, on the features you use or your age. The developer, WhatsApp Inc., indicated that the app’s privacy practices may include handling of data as described below.

This would give them some context for why they are important, and that will lead them to pay for more services like this – or so the hope goes. The idea, he said, is to develop a group of basic internet services that would be free of charge to use – “a 911 for the internet”. That year, the company had $148 million in expenses and a net loss of $138 million. Koum then hired a friend in Los Angeles, Chris Peiffer, to develop a BlackBerry version, which arrived two months later. Although Acton was working on another startup idea, he decided to join the company. Koum updated WhatsApp so that everyone in the user’s network would be notified when a user’s status changed.
