If you’re a student, you probably have one app for studying and another for calming your nerves. Switching between the two every time stress kicks in gets old fast. Yellow Lion is tackling this problem with Caldo, a new iOS app that mixes adaptive learning games with guided breathing, so you can do both at once.
You get access to over 50 learning games covering a range of subjects. You don’t pay anything to get started, so you can start playing right away.
The standout feature is Caldo AI. Feed it your notes or textbooks, and it will turn them into games, adding a breathing exercise to each round. Get a question wrong, and you can tap the Enlighten button to see a hint, some background, and where the information comes from, instead of just the answer.
Caldo, a meditating sloth with a relaxed, friendly personality and a good sense of humor, guides you through it all. I can’t think of a better mascot for an app that wants you to slow down.
Test stress affects more students than you might expect. After pooling data from 67 studies, researchers found that nearly half of students (48.43%) deal with measurable exam anxiety. Other research shows mindfulness can sharpen focus, help working memory, and ease test anxiety.
According to Yellow Lion, no other app has placed these calming tools inside the study session before. If you have ever stared blankly at your notes the night before an exam and got more stressed by the minute, Caldo might be worth a try.
Are you tired of paying for streaming services you never watch just to get a phone plan feature you actually want? T-Mobile has good news for you! The carrier is rolling out new plans, called T-Mix, in early November to replace its old Experience lineup with a build-your-own perks system called Picks.
The benefits you choose vary from streaming and gaming to food delivery, AI, satellite service, and phone discounts. But if you are satisfied with your existing plan, you can keep it.
Merely days after the iPhone Duo hit the shelves, images of broken screens on the phone started popping up across social media. Until now, it’s been unclear what’s causing the line of defective pixels that appears vertically along the crease, as well as horizontally, on the phone’s inner display.
Apple has finally acknowledged the issue, which has shown up on iPhone Duo units owned by customers as well as demo units in stores. In a statement shared with Bloomberg, Apple says that not all iPhone Duo units are affected and that those that are tend to show the display fault early on. The company added that users who experience problems with their iPhone Duo display should contact AppleCare for a replacement.
Not long ago, Apple treated independent repair like an act of outright hostility. The Cupertino giant locked down parts with serial-number pairing, while repair tools remained firmly out of reach of anyone outside its authorized repair network. More importantly, the company waged a legal and lobbying battle against right-to-repair legislation.
I've covered enough of these fights over the years to know what a shift looks like. That's why what happened in October 2026 genuinely caught me off guard. The day the iPhone Duo went on sale, what may be the most mechanically complex iPhone to date, Apple pulled off a surprising about-face. It published teardown-style repair manuals for a handful of major components.
