Verum, Wickr and Threema: next generation secured messengers

Still using WhatsApp and Facebook Messenger? Think Telegram is completely reliable? Or maybe you still can’t give up trying to talk normally in Viber? Then we have a serious conversation with you.
The 21st century has given us access to communication, instant communication with each other, no matter where we are in the world. But at the same time, we all became vulnerable — personal information was in plain sight, it was easy for us, we were simply controlled. Conversations are no longer private. “You have to pay for everything. This is the price of an affordable connection”, someone might say. No, we disagree with this statement. Everyone has the right to the confidentiality and secrecy of their data. We present you the top 5 most secure messengers of the new generation.
Verum
https://apps.apple.com/app/verum-messenger-chat-calls/id1550499454
You don’t even need a SIM card to use Verum messenger. No phone tethering. The app has built-in VPN and end-to-end encryption. When you first get to know the application, you will create an individual key pair and you will have a unique identifier. And the Verum developers have solved our eternal problem — if someone takes a screenshot in the chat, you will immediately find out about it. Checkmate! No more leaked correspondence. You can add up to 10,000 people to a group chat, and the app is translated into 15 languages. No one, except the recipient, can view your correspondence, no matter what it contains — photo, video, audio. And even if you suddenly lose your phone, no one but you will be able to enter the application. To do this, you can set a password for the entrance or require it to be entered after a certain time. And so that you are completely calm about the confidentiality of communication, the Verum developers have provided the ability to automatically delete all correspondence after the time you set. The interface is minimalistic and stylish. Verum is currently only available for download on IOS. It can be purchased from the App Store for $12,99. Yes, it is paid, like some of the ones below, as these are the best messengers in terms of security. But, believe me, those «free» applications that are on your phone also have a price — you pay for them with your personal data.
Wickr
Time-tested anonymous messenger. Even if you have never come across it face to face, you are sure that you have heard this name for sure. As with Verum, you do not need to have a SIM card in order to attach the app. When registering, you create an ID and password. Transferring files to third parties is impossible, as well as a screenshot of the correspondence. If you decide to erase the entire communication history, there is no way to restore it. The developers have equipped the Wickr feature with a temporary image and text that will automatically disappear after the recipient has viewed them. It is very convenient that the messenger can be installed on a PC, as well as by the standard — available for IOS and Android. Wickr is available in a free version (Wickr me) and also in a paid version (Wickr pro / Wickr ent) for corporate communication. Due to this interface, the application is a little more complicated than that of other messengers.
Threema
Application servers are located in Switzerland, which in itself, you must agree, is already a guarantee of quality. Just like the previous applications — Verum and Wickr — Threema does not require you to bind to a phone number. And we like this trend, as it has long since lost its relevance. Something like a place of registration, isn’t it? Instead of a number, you will be given keys — private and public, according to the scheme you are already familiar with. It is also possible to password-protect individual chats. The information is not saved in the application, but on your phone. Messages are deleted immediately after you or your interlocutor read them. Everyone began to discuss Threema after the messenger refused to give out encryption keys to Roskomnadzor. After this incident, the number of users of the application increased significantly. Threema can be downloaded on IOS and Android for about 3$.
Confide
A very interesting, in our opinion, application for safe communication. The peculiarity of this messenger is that messages are displayed closed, in the form of rectangular shapes. In order to read the text, you will need to slide your finger over it. This feature protects you from annoying peeping at the phone screen. Until you make sure that no one is standing behind you, the message will be impossible to read. True, Confide requires binding to your mail. Here, too, it will not be possible to take a screenshot, since you simply cannot then open it or send it to someone. The app is free, but there are paid features.
Signal
To install this application, you will already need your phone number and contact list. Despite this breach of anonymity, the messenger is still pretty safe. Developers used open source encryption, making it available to their own research of various problems that may arise when working on different operating systems. Unlike WhatsApp, Signal will not collect data about your preferences, after which you are usually offered an advertisement for the product you just hinted at in a conversation. Before starting a conversation, you can double-check the security of your conversation thanks to the additional two-way session verification. The developers have also not forgotten about the function of disappearing messages. You can set a password to sign in to Signal, or you can use the face and fingerprint recognition system. The application is free and available for all operating systems.

Galaxy S25 Edge Hands-On: This Thin Phone Left a Deep Impression
At 5.8mm thick and 163 grams, this slim phone packs many of the features you’ll find on other S25 series devices. But the unique design is a breath of fresh air.

As I hold Samsung’s super-thin and light Galaxy S25 Edge, the first word that comes to mind is «airy.» My next thought is: If I were the S25 Plus, I’d be worried.
In my early hands-on with the S25 Edge at a preview event in New York, I was struck by how much the new phone carries over from its S25 counterparts. It maintains the 200-megapixel wide camera from the S25 Ultra, the 6.7-inch display from the S25 Plus and the Snapdragon 8 Elite processor you’ll find across the other three S25 devices. But it does so within a sleek, 5.8mm titanium frame, clocking in at 163 grams. It feels like something I can throw in my bag or pocket and hardly notice.
In fact, the S25 Edge strikes me as exactly what a middle-of-the-line flagship phone should be: a fresh, elevated take on the baseline model, which pulls in premium features to justify its $1,100 price. The exciting design, Ultra-level wide camera and spacious display actually make this an enticing option for anyone who wants something a little out of the ordinary.
But that’s not to say there aren’t any compromises in store, the most notable being the battery; more on that later.
Preorders for the Galaxy S25 Edge are open now, and the phone will arrive on May 30. It comes in three colors: silver, jet black and icy blue.
What makes the S25 Edge stand out
The biggest question leading up to the release of the S25 Edge has been: Why would someone want a thinner phone anyway? After spending a little time with the device, I began to see the appeal.
While the S25 Edge’s thickness may not be visually striking at first glance, getting your hands on the phone is a different story. Comparing how the S25 Edge’s 5.8mm, 163g frame feels to the S25 and S25 Plus, I registered just how much thinner and lighter it really is. For reference, the baseline S25 is 7.2mm thick and weighs 162g, but has a smaller 6.2-inch screen. The S25 Plus has the same 6.7-inch display as the Edge, but is 7.3mm thick and weighs 190g. It’s a noticeable difference.
The moment of truth was applying some force to the phone to see if it gave at all. Impressively, it felt quite sturdy. (If not, I’d probably have gotten myself into some trouble with Samsung.) It touts a Corning Gorilla Glass Ceramic 2 display, along with a Gorilla Glass Victus 2 backing. My initial impression is that you shouldn’t have to worry about accidentally turning the S25 Edge into a foldable by keeping it in your back pocket, but that’s certainly something I’ll have to test in my review. The S25 Edge also maintains the same IP68 rating for dust and water resistance you’ll find on the other S25 series phones.
The biggest trade-off, at least on paper, appears to be battery capacity. The Galaxy S25 Edge’s 3,900 mAh battery pales in comparison to what you’ll get on the baseline S25 (4,000 mAh) and the S25 Plus (4,900 mAh). Samsung isn’t sharing how many hours you’ll get out of the S25 Edge’s battery, other than stating it’ll last you all day. That’s something else I look forward to testing. The S25 Edge supports 25-watt wired charging and 15-watt wireless charging.
With thinner phones, camera hardware can also be scaled back. But the S25 Edge boasts three cameras: a 200-megapixel wide, a 12-megapixel ultrawide and a 12-megapixel selfie camera. Megapixels aren’t everything, so I’m eager to see how that all translates into real-world photography. Samsung points to Galaxy AI for helping to boost camera quality and for powering photo editing features like Generative Edit.
Like the S25 Plus, the S25 Edge has 12GB of RAM and 256GB and 512GB storage options. It’ll cost a little more than the S25 Plus, though: $1,100 for 256GB and $1,220 for 512GB. But it’s still priced lower than the top-of-the-line $1,300 S25 Ultra.
You’ll find the same Galaxy AI features Samsung has been touting on the rest of its S25 phones, like Sketch to Image and Audio Eraser. Gemini features are also onboard, like Gemini Live and Circle to Search.
On the edge of a new trend
The launch of the Galaxy S25 Edge comes amid a thin-phone phenomenon. Earlier this year, Oppo released its super-thin Find N5 foldable, which it calls the «world’s thinnest book-style foldable,» measuring just 8.93mm thick when closed and 4.21mm thick when opened. Apple is also rumored to be developing a thinner «Air» version of the iPhone 17. And at MWC 2025, phone maker Tecno showed off its Spark Slim phone concept, which measures 5.75mm thick and weighs just 146 grams, according to the company.
Depending on how consumers respond, the S25 Edge could be the phone to help kickstart the thin phone craze. If people don’t have to compromise too much when it comes to camera, storage and battery — three of the biggest considerations when buying a phone, according to a CNET survey — they could be inclined to pay up for a fresh form factor. After all, phones have become rather boring and predictable, apart from a handful of foldable options. The S25 Edge could be a breath of fresh air.
I look forward to seeing how the S25 Edge holds up in the real world and whether it truly can maintain its edge (I had to do it).

OpenAI Launches HealthBench, a Dataset That Benchmarks Health Care AI Models
This is a major leap by the ChatGPT creator into health care.

OpenAI, the creator of artificial intelligence chatbot ChatGPT, has a new open-source large language model called HealthBench that lets the health care industry benchmark AI models, the company said in a blog post on Monday.
The model was built in partnership with 262 physicians across 60 countries, and has 5,000 realistic health conversations baked in. The goal for HealthBench is to discover whether AI models are giving the best possible responses to people’s health-related inquiries. Each response is measured against a physician-written rubric criterion, with each criterion weighted to match the physician’s judgement. The rubric is scored by GPT-4.1.
OpenAI’s o3 reasoning model performs the best, according to HealthBench, with a score of 60%, followed by Elon Musk’s Grok at 54% and Google’s Gemini 2.5 Pro at 52%.
In an example on OpenAI’s blog post, it posits a scenario where a 70-year-old neighbor is lying on the floor, breathing but unresponsive. The person asks AI what should be done. A model then gives an answer with steps on what to do, such as calling emergency services, checking breathing and positioning airways. HealthBench then scores the response, explaining what the model answered correctly and what could be improved upon. It then gives a final score, in this case, 77%.
The model can handle 49 languages, including Amharic and Nepali, and includes 26 medical specialties, such as neurological surgery and ophthalmology.
OpenAI didn’t immediately respond to a request for comment.
