Twitter co-founder Jack Dorsey introduces early version of bluetooth messaging app, Bitchat
'[M]y weekend project to learn about bluetooth mesh networks, relays and store and forward models, message encryption models, and a few other things. bitchat: bluetooth mesh chat...IRC vibes,' posted Dorsey on X on Monday (July 7, 2025), likely referring to the aesthetics of Internet Relay Chat protocols from the past.
According to a graphic that Dorsey shared, Bitchat will include features such as offline communication up to a range of more than 300m, end-to-end encryption, topic-based rooms, password-protected rooms, mentions, and a 'favourites' system. So far, the design appears to be minimalistic and resembles a programming or coding surface in terms of its UI.
Privacy is set to be a key factor, as Dorsey noted that there would be no servers, accounts, or data collection.
'[B]itchat addresses the need for resilient, private communication that doesn't depend on centralized infrastructure. By leveraging Bluetooth Low Energy mesh networking, bitchat enables direct peer-to-peer messaging within physical proximity, with automatic message relay extending the effective range beyond direct Bluetooth connections,' noted Dorsey in a whitepaper that he shared.
An early version of Bitchat is currently undergoing its app store review, he told another X user. The app has also hit its beta tester limit.
Dorsey previously worked on the social media platforms Twitter (now X) and its decentralised off-shoot Bluesky. However, Musk bought X and Dorsey is no longer associated with Bluesky.

Whoop 5.0 vs 4.0? What's The Difference?
Fitness trackers are becoming increasingly popular day by day. These days, even people who aren't into fitness want a fitness tracker because it's not just about the steps but about being informed and motivated. If you are someone who is into fitness, then the Whoop fitness tracker is something you must have heard of. This smart wearable is designed to monitor your body's performance day and night. After the success of Whoop 4.0, the brand is back with its latest version, the Whoop 5.0. But with the launch of Whoop 5.0, many are asking the big question: What's new compared to Whoop 4.0? Read more to know the major difference between Whoop 5.0 and 4.0, and what remains the same. Better Bluetooth Connection One of the major problems in Whoop 4.0 was its connection issues, especially when syncing with fitness apps or smartwatches. With 5.0, those problems are largely fixed as it has been upgraded to dual-band Bluetooth. In simple words, it connects more smoothly and reliably to your phone and other devices. More Accurate Tracking in Tough Conditions Whoop 4.0 faced some tracking issues during intense workouts. Whoop 5.0 brings improved heart rate tracking, even during intense workouts. Whether you're running, cycling, or doing high-intensity training, you'll get more accurate readings thanks to upgraded sensors. Better Compatibility with Other Devices Fitness lovers often use multiple gadgets. Whoop 5.0 makes it easier to pair with devices like smartwatches, gym equipment, or apps like Apple Health and Strava. This wasn't as smooth on the 4.0 version. Same Design The sleek, screenless design of Whoop made heads turn and became its identity. That's the reason the brand decided not to bring major changes to the design. It's light, comfortable, and meant to be worn all day and night and even in the shower. Battery Life Remains the Same Both Whoop 4.0 and 5.0 offer around 4–5 days of battery life, which is pretty impressive considering they track you 24/7. You still get the handy on-the-go battery pack, so you don't need to take it off to charge. The Main Question – Should You Upgrade? If you are already using the Whoop 4.0 and it works well for you, then the upgrade is not really necessary. But if you want better connectivity, improved accuracy, and a smoother experience with your other fitness devices, Whoop 5.0 is a smart move.

Edelweiss MF CEO Radhika Gupta slams fashion brand for selling Lucknowi mukaish overcoat for Rs 1.7 cr: ‘World loves Indian craftsmanship but..'
Indian craftsmanship , long admired on the global stage, serves as a rich source of inspiration for numerous international fashion and lifestyle labels. However, the true creators behind these intricate works—skilled artisans—are often overlooked, living in the shadows without recognition or reward. Despite the international reverence for their art, the artisans themselves remain nameless, and their contributions are unacknowledged. Recently, Radhika Gupta, CEO of Edelweiss Mutual Fund and a known advocate for creative integrity, publicly criticized a well-known luxury fashion brand for exploiting India's iconic Lucknowi mukaish embroidery. This traditional technique, rooted in cultural heritage and meticulous craftsmanship, was allegedly used in one of the brand's high-end coats—priced at an exorbitant $200,000 (approximately Rs 1.7 crore)—without any credit to the original artists or reference to its Indian origins.

According to her, the elaborate coat was the result of the efforts of 12 Indian artisans who spent 34 days crafting the embroidery. Despite the time, skill, and heritage invested in the piece, the brand failed to acknowledge the origin of the art form or the artists who made it possible. Gupta highlighted how this is a recurring issue in global fashion—Indian crafts are often celebrated visually but stripped of their backstory and the rightful credit to the creators. "12 Indian artisans. 34 days of work. No credit. No context. No mention of India. The world loves Indian craftsmanship—but rarely credits the craftspeople. And almost never shares the value," she lamented. She stressed that while the world continues to benefit from Indian aesthetics, the power to shape narratives, pricing, and branding remains with those outside the country. This imbalance means that while the finished product dazzles on global runways, the hands that built it remain invisible. Mukaish embroidery, deeply embedded in the history of Lucknow, involves weaving metallic threads into fabric to form delicate, web-like designs. Known locally as fardi ka kaam , this embroidery creates striking geometric textures. Traditionally combined with chikankari, another Lucknow-based hand embroidery, mukaish is considered a vanishing art. Few artisans continue to pursue it today, and even fewer receive the credit they deserve. Gupta called upon India to transform from merely a supplier of materials to a powerful storyteller of its heritage. Just as Japan and Korea leveraged design and pop culture to build global influence, India, she argued, should assert its cultural authority through its rich and unparalleled crafts. Ask ChatGPT

Under a Thousand: A Bubble-y keyboard for tablet-types!
Bluetooth keyboards have long been considered must-have accessories for those who wish to use their tablets (whether iPads or Android ones) in notebook mode. The catch is that most good Bluetooth keyboards not only come with slightly stiff price tags, but also that they have no facility to prop up a tablet, so one has to invest in either a stand or a tablet cover with a stand. Logitech showed that it is possible for a Bluetooth to also have a space for placing gadgets like a phone or a tablet in its famous Logitech K480 keyboard, but that came with a Rs 3,999 price tag (it is more affordable now, but is not as useful given the straight side design of tablets and phones). Also, most of the lower priced Bluetooth keyboards tend to be a little on the smaller side, and sacrifice functionality for the sake of a more affordable price tag. Portronics is looking to change all that with the Bubble 3.0 wireless keyboard, which has been launched recently at Rs 999, and comes loaded with features. The first thing that strikes you about the Portronics Bubble 3.0 is just how sturdily built it is. At 39 centimeters in length, it is on the long side, and is about 3 centimeters tall when placed on its retractable stand. At about 800 grams, it is slightly on the heavier side, but has a very solid feel about it. The keyboard is available in a single colour, black, at the time of writing, and it cuts a smart figure. It has a six row alphabet and shortcut layout, and on its right side, a full number pad. Its most striking feature is a long, trench-like depression above the top row, which Portronics calls the 'mobile and tablet holder space.' It is very similar to what we have seen on some other keyboards, but in a neat touch, the Bubble 3.0 also has small pads on the upper side of the holder space to keep tablets and mobile phones steady, reducing the chances of their tipping over and falling (something that now happens with the Logitech K480, thanks to the straight-side design of gadgets). The right side of the keyboard has a type-C port for charging, while on the back of the keyboard are two retractable legs or stands that can be pulled out to give one a slightly higher perspective, The mobile and tablet holding space on the top is large enough for a tablet and a phone to be kept side by side if needed. Most of the keys are round in shape and are slightly on the smaller side, but are well spaced out and have decent travel, to give you a slightly punchy feeling while typing. Of course, the keyboard is not backlit, hut there are three connectivity keys that are in white to allow you to switch between connected devices. There is also a tiny display on the top right corner, right above the number pad, which shows the devices to which you have connected the keyboard to, and also lets you know when you need to recharge the battery – a very handy touch which we hope other manufacturers pick up. Next to it is a slider that lets you switch off the keyboard, and move it into wireless or Bluetooth mode. The spacebar comes with large Portronics branding, which looks a little loud (the branding could have been placed more subtly), but all said and done, the Portronics Bubble 3.0 looks like a big, solidly built keyboard. The Portronics Bubble 3.0 works very well too. Pairing it in wireless mode is as simple as attaching the USB connector to the tablet or notebook (which can be a bit of a challenge, as it is a USB Type A, and will not plug straight into most tablets, so you will need an adaptor) and then type away. The process is slightly more elaborate when you connect the device over Bluetooth – you need to press the Fn key and one of three buttons, and then choose the keyboard in the Bluetooth settings of the device. You can use this process to connect up to three devices to the keyboard, and keep switching between them, by hitting the white key you have linked to each device. We connected the keyboard to our OnePlus Pad 3, iPad Air 13 and iPhone 16 Pro Max, and while the switching is not super smooth – there is a clear pause as you move from one device to an other – it is pretty effective. Interestingly, both the OnePlus Pad 3 and the iPad Air 13 are large tablets, but we found we could use them in portrait as well as landscape mode in the holding space, without ever worrying about them tipping over (we recommend keeping the stand out for greater stability). The typing experience on the Portronics Bubble 3.0 is a good one. As we mentioned earlier, the keys are not large, but they have decent travel and for the most part, typing is a smooth process. The number pad is handy, and the row of shortcuts on the top of the keyboard also make the whole typing process easier, by letting you change volume, open mail, and switch to the home screen by just tapping two buttons (the Fn key and the relevant button). We would have ideally liked to have to hit just one button to use a shortcut, but this is hardly a deal breaker. You will also need to get used to the key layout and shortcuts, but once you get the hang of it, the Portronics Bubble is a solid performer. Battery life is pretty good too. Portronics has given non official figure in this regard, saying that the keyboard can last for 'days' on a single charge, and we have so far used the keyboard for almost five days without needing a recharge at any stage, The presence of USB Type-C charging means you can recharge the keyboard using your phone's charger, and do not have to worry about carry AAA cells along. We would have liked to be able to see the level of charge left in the battery, though. The Portronics Bubble 3.0 does have its issue. Although Portronics has provided a number pad, the arrow keys on the main keyboard are on the small side – we ended up using the ones on the number pad. And while the existing shortcut keys are handy, there is no screen lock/unlock key, which meant we had to keep reaching out to swipe up on our tablets,. which can be a little inconvenient. Finally, there is the matter of weight and size. The Portronics Bubble 3.0 is actually longer than most notebooks, so it is not very easy to carry around unless you have a very spacious backpack. However, those are minor quibbles when one considers what the keyboard delivers at its price. For less than a thousand Rupees, one gets a full keyboard with a number pad and space to prop up a tablet and/or phone, multi-device connectivity, USB Type-C charging, and Bluetooth as well as wireless connectivity. All in a sturdy enough design. It is not perfect (what is?), but you are unlikely to get a better Bluetooth keyboard deal at this price, especially if you value a number pad and want a keyboard that can handle multiple devices, without you having to invest in a stand to prop[ them up on. It will take a bit of space in your backpack and add to its weight too, but we think it is well worth it, given its amazing price tag.
