Now that Amazon's Prime Day is in full swing we've rounded up the best Prime Day deals under 50 on the smaller tech we love. As with all Engadget tech deals coverage, we only highlight discounts on gear we've tested or have otherwise used and know to be worthy of your money.

That's a 15 percent discount and a good deal for one of the best power banks we tested. We like the foldable USB-C connector which means you don't have to remember a separate cable and the amount of charge it delivers for such a small package. Plus it's compact enough you can use it while it refills your phone.

Prime Day robot vacuum deals include this Shark AI Ultra machine for half off

Engadget

The only thing better than a robot that vacuums for you is one that empties its own dust tray, too. The popular Shark AI Ultra robovac, which is normally a hard-to-swallow 600, is half off for Prime Day, bringing the cost down to just 295. You can control this vacuum with voice commands -- it supports both Amazon's Alexa and Google Assistant -- and it uses Matrix Clean Navigation to make sure it hits every spot in your home.

Prime Day discounts the Apple Watch Series 9 to a record low of 280

Engadget

It's a great time to get the Apple Watch Series 9 if you've been planning to buy one -- the smartwatch is currently on sale for 280 for Amazon Prime Day. That's a pretty impressive 119 discount as part of Prime Day deals, and it's even 15 lower than its previous all-time low, but the deal appears to be specifically for the smaller 41mm model. It's our best smartwatch for 2024 so far, though it first became available in September last year. We gave the Apple Watch Series 9 a score of 92 in our review and praised its on-device Siri for having the capability to work offline and even when the wearable isn't connected to a phone. If you don't want to take your phone with you to the gym, for instance, that's no problem: You'll still be able to ask Siri on your watch for health data, like the number of steps you'd already taken.

Engadget

Amazon Prime Day is finally here, and you can score excellent discounts on most of Amazon's own devices. One deal of note is on the Echo Show 5, which you can snag for only 50 right now. The Echo Show 8 is also on sale for 85, which is a new record low. The Echo Show 5 easily made our list of the best smart displays, for a great many reasons. The 5.5-inch screen is diminutive, especially when compared to the Echo Show 8, but that just makes it fit better on a desk or nightstand.


NudgeRank: Digital Algorithmic Nudging for Personalized Health

arXiv.org Artificial Intelligence

In this paper we describe NudgeRank, an innovative digital algorithmic nudging system designed to foster positive health behaviors on a population-wide scale. Utilizing a novel combination of Graph Neural Networks augmented with an extensible Knowledge Graph, this Recommender System is operational in production, delivering personalized and context-aware nudges to over 1.1 million care recipients daily. This enterprise deployment marks one of the largest AI-driven health behavior change initiatives, accommodating diverse health conditions and wearable devices. Rigorous evaluation reveals statistically significant improvements in health outcomes, including a 6.17% increase in daily steps and 7.61% more exercise minutes. Moreover, user engagement and program enrollment surged, with a 13.1% open rate compared to baseline systems' 4%. Demonstrating scalability and reliability, NudgeRank operates efficiently on commodity compute resources while maintaining automation and observability standards essential for production systems.
