There have been many updates to the messaging app over the past year, especially for the iPhone version of the app. These updates include easier photo and video sharing capabilities, a redesigned interface, and the option to queue messages. These options, however, aren’t yet available on Android.

WhatsApp, owned by Facebook, is one of the most popular messaging platforms in the world with over 1 billion users. Along with this potential messaging update, the app also recently launched a video-calling platform similar to Apple’s Facetime.

Prior to this update, users were unable to recall messages that were already sent. However, with the update, if the message has not yet been sent to the recipient — due to a lack of Internet connection or service — it is possible to stop the sending of the message to the recipient by deleting the message from the device.

This new option would open a new world of text messaging. Previously, any accidental or regretted text messages would eventually be read by the intended recipient. Since the app is available in over 50 countries and in dozens of languages, this potential update could positively affect millions around the globe who use the app daily.

In order to turn this feature on, users must restart their phones and find the options buried within the WhatsApp menu options. Without this update, users can still delete messages from the app, but they will still be visible to the recipient. Now, they can be both edited and revoked as long as they remain unread. If this feature proves useful to iPhone users, it will only be a matter of time before it comes to Android devices.

In other news, WhatsApp recently hired Matthew Idema, a former senior executive at Facebook, to be their first chief operating officer, or COO. This new role has been supposedly created in an attempt to help WhatsApp monetize its platform. Idema, who has a strong background in startups and Silicon Valley, helped launch Facebook Messenger and other applications while with the company.

How do I create a Kik account?

Unlike other popular messaging apps, including WhatsApp, Kik doesn’t have you input your phone number to create an account. Instead, you create a messaging account with your email and a password. You can then find your friends by searching for their usernames or by searching for their phone numbers once they’ve entered those into the app.

Who uses Kik?

Bottom line? Lots and lots of people use Kik. From 2010 to 2012, the Kik app attracted over four million users. But by 2016, Kik had exploding, drawing in more than 275 million users.

Why would I use Kik?

Kik operates in a way that’s very similar to your phone’s normal texting plan. If you’re worried about going over your texting limits, Kik can be a great way to save your texts for when you’re away from a Wi-Fi connection. Unlike texting on your phone, you won’t run down your texting plan with Kik. Instead, you connect via your data plan or Wi-Fi. Most people use Kik as an email, social media chat, or texting alternative.

What are Kik features?

Kik has some features that not all Android texting apps provide. Its live typing feature, for example, lets you know when the person you’re texting is typing. It also lets you know when your text recipient has read your text.

Another useful Kik features is its customizable notification sounds – you can change the noise your phone makes when a certain person texts you. Additionally, Kik’s code scanning is a unique feature. Each Kik user has a personalized code that can be accessed in the app’s settings. To add a user with their Kik code, you can simply give Kik permission to access your phone’s camera and then scan another user’s Kik code to add them.

While you’re Kik-ing up a storm, don’t waste all your memory and storage space. Instead, optimize your phone with PSafe Total. PSafe’s Memory Booster gives you options for clearing out unneeded files from storage and optimizes your data — all designed to speed up your device.

1. Signal

Let’s start off with the most well-known of the three. Signal is a messaging system you can use to start group chats, avoid SMS fees, and share pictures, videos, GIFs, and other media files, all while keeping everything on a private, need-to-know basis. The app uses end-to-end encryption, and the code can be verified by anyone who wants to audit it, since it’s an Open Source app.

You also don’t have to go through the hassle of creating an account, since it uses your phone number, and address book for setup. Furthermore, it’s designed to operate at a high standard, facilitating instant message delivery, and crystal clear phone calls (that don’t come with long-distance charges).

2. Wickr

Although it’s a lesser-known app, and although it operates differently from Signal (you have to make a [free] account), the team behind Wickr promises total security, and includes various features that will attract anyone who takes privacy seriously. For instance, its Shredder feature lets users permanently remove all deleted messages, images, and video content from their devices. You can even use the Configurable Timer to set an expiration time for the messages you send and receive, so they’ll only last as long as you want them to.

The app also automatically removes all identifying information, like geotags, check-ins, and any other records, from any messages you send in-app. As icing on the cake, Wickr also did a $100,000 Bug Bounty in 2014, which means its team offered $100,000 to anybody who could break through their security measures. That confidence has to be founded in something, right?

3. CoverMe

This app shares most, if not all, of the features above, serving as a solid, user-friendly alternative for those who aren’t satisfied with the other two. With this app, you can call people in a cost-free, private manner, have your messages self-destruct, recall or completely wipe messages you’ve already sent, and share and hide any media files you choose.

Hidden and Secure

All of these messaging apps are great, but what do you do if you want to stick to the messengers you already love — like Facebook Messenger or WhatsApp? Well, you’re in luck, because PSafe TOTAL has got you covered. With its Applock feature, PSafe TOTAL provides these apps with password protection, so you can make sure no one accesses your private messages without your say so.
