Now Jack Dorsey has built an app to track your vitamin D

Sun Day is available now for iOS via TestFlight, and the code for the project is available on GitHub. The app uses location-based data to display your local UV index and sunlight hours. You can detail your skin type and clothing level, then manually toggle when you’re in and out of the sun and the app will track your rough vitamin D levels for the day, along with how long you can be in direct sunlight without burning.

Where are the iPhone’s WebKit-less browsers?

It’s been 16 months since a DMA ruling allowed iOS developers like Google and Mozilla to use their own browser engines in the EU, so… where are they? According to the Open Web Advocacy (OWA) — a nonprofit group of software engineers that advocates for the open web — Apple continues to place technical and financial restrictions on WebKit-alternative iOS browser engines that effectively stifle competition. OWA says these barriers include insufficient testing tools outside of the US, hostile legal

AirTag 2: Here’s what we’re expecting

Apple has long wrapped up its spring releases, including the new iPhone 16e, M4 MacBook Air, M3 iPad Air, and A16 iPad. While the iPhone 17 lineup will certainly be the star of the show for this fall’s hardware releases, there’s something a bit unique coming later this year: AirTag 2. Why AirTag 2 Despite the fact that it sounds like an uninteresting refresh, AirTag 2 will actually pack a number of relatively important upgrades for the everyday user.

These are the pros and cons of buying from Apple’s refurbished store: Is it worth it?

Apple has long offered a refurbished store on its website, where it sells recent generation products at a pretty sizable discount. Unlike other refurbished offerings, Apple guarantees a replaced outer shell, battery, and glass – ensuring no wear and tear. You also get a 1 year Apple warranty and the ability to add AppleCare if you’d like. That sounds great, but is it actually worth it? Well, it depends. We’ll be delving into Apple refurbished listings, and comparing it to other offerings on the

This is the best cross-platform 2FA app I’ve used — and you should try it too

Karandeep Singh / Android Authority When a sizeable chunk of online attacks involves weak passwords and unauthorized account access, second-factor authentication (2FA) is one of those magic bullets that can save your digital life from getting compromised. But they’re only usable if they don’t become an inconvenience themselves. Inconvenient — that’s exactly what a lot of 2FA apps have been for me. Some wanted to lock me down to their app, some had themselves been compromised, while others were

Report: Apple’s all-new smart home hub is no longer likely to launch this year

The all-new smart home hub was supposed to be Apple’s star of the show this year. There was just one problem: Siri. After a multitude of Siri hiccups and delays, it begun to look more and more unlikely that the product would launch in 2025. Now, Bloomberg’s Mark Gurman is reporting that a 2026 launch is almost a guarantee. Originally, it seemed all but confirmed that we’d see the Apple smart home hub around March or so. The product was well rumored throughout 2024, and we essentially know every

Jack Dorsey’s New App Just Hit a Very Embarrassing Snag

Serial entrepreneur Jack Dorsey, who cofounded Twitter, Block, and Bluesky, has started yet another new app — and this one's got an embarrassing secret. As TechCrunch reports, Dorsey's new open source messaging app, Bitchat, is supposed to be decentralized, private, and secure. There's only one problem: the Bluetooth-based app, by the venture's admission, is probably lacking in that key regard. "This software has not received external security review and may contain vulnerabilities and does n

Cops say criminals use a Google Pixel with GrapheneOS — I say that’s freedom

Calvin Wankhede / Android Authority Police in Spain have reportedly started profiling people based on their phones; specifically, and surprisingly, those carrying Google Pixel devices. Law enforcement officials in Catalonia say they associate Pixels with crime because drug traffickers are increasingly turning to these phones. But it’s not Google’s secure Titan M2 chip that has criminals favoring the Pixel — instead, it’s GrapheneOS, a privacy-focused alternative to the default Pixel OS. As som

Show HN: BinaryRPC – Lightweight WebSocket-based RPC framework in modern C++

BinaryRPC 🧭 Motivation While working at my company, I had previously developed a WebSocket server prototype in Java. However, over time, we started to experience performance issues. This led me to turn to C++, a language that offers more speed and low-level system control. Through my research, I discovered that uWebSockets was one of the best options in terms of performance, so I began developing with this library. However, since uWebSockets is a very "core" library, I had to handle many deta

My top 6 open-source Android apps from the Google Play Store - and why that's important

Joan Cros/NurPhoto via Getty Images Android and open source are closely intertwined. In fact, most open-source fans I know also use Android. Coincidence? I think not. One nice thing about Android is that the Google Play Store has lots of open-source software. That's not to say every single open-source title is worth your time and effort, but there are plenty of FOSS apps that are not only worth your time but also some of the best in class.

A US-Only TikTok Replacement App Could Be Coming. What We Know So Far

A new US-only version of TikTok is being developed by the vertical video app's owner ByteDance, and will replace the current version of TikTok ahead of a September deadline for the Chinese company to divest ownership in the US, according to a report this week by The Information. The new app, codenamed "M2," would launch on Sept. 5 and would require users in the US to switch from the existing app to the new one, the report said, citing anonymous sources.

Samsung's Galaxy Unpacked event in Brooklyn earlier this week debuted seven new devices, from the Galaxy Z Fold7 to the Galaxy Watch8 series. But there weren't any surprises at the end, despite rumors that Samsung would unveil a trifold phone. Sensing disappointment, the company later confirmed that the phone is expected to land in 2025. “I expect we will be able to launch the trifold phone within this year,” TM Roh, head of Samsung's mobile business, told The Korea Times.

Report: Apple set to land US F1 streaming rights in $150 million+ deal

Earlier this week, the Financial Times reported that Apple was in active negotiations to acquire the streaming rights for Formula 1 in the United States.
