We’ve compiled our most popular YouTube videos of 2025 — from next-gen devices and major industry updates to real-world diabetes tech reviews and walkthroughs. In case you missed one, here are our top 10 videos of the year.

Continous glucose monitors (CGMs) made a major leap in 2025 and this video covers how every big player made moves. Dexcom pushed boundaries with a 15-day G7 and a surprising expansion into wellness alongside Oura. Abbott quietly leveled up the Libre experience with smarter alerts and deeper integration into automated insulin delivery systems. Medtronic expanded their lineup with Simplera Sync and the Instinct CGM, and Eversense’s year-long implantable CGM is getting integrated into a hybrid closed-loop system.

Medtronic has officially stepped into the next-gen pump race—and it’s bigger than just one device. This video dives into two new insulin pumps in the works, one tubed and one tubeless, with some pretty bold design choices. The first is a pump that’s nearly half the size of the 780G, no screen at all, fully app-controlled, and heading into a pivotal stud. And on the tubeless side, a modular design, 7-day wear, and a lot of unanswered questions about when it’ll actually launch.

The future of insulin pumps is looking smarter, simpler, and more customizable than ever. In this video, we dive into insulin pumps coming in 2025 and beyond, from tubeless and screenless designs to all-in-one pump-CGM systems, longer-wear infusion sets, and fully closed-loop algorithms. We break down what’s already in development from companies like Beta Bionics, Tandem, Medtronic, Omnipod, and what the upcoming generations should look like.

The next generation of CGMs looks nothing like what we’re used to today. In this video, we explore emerging technologies, from long-lasting implantable sensors like Glucotrack’s blood-based CGM and Eversense’s fully implantable Bluetooth system to needle-free, multi-analyte wearables from Biolinq, Sava, and Trinity Biotech. We also break down some of the boldest ideas in development, including brainwave-based glucose tracking and the laser-driven approaches from Apple and Samsung.

This deep dive looks at the upcoming tubeless version of Tandem Mobi, expected to arrive in 2026, including how its new patch-based design works, how it stacks up against Omnipod, and why its FDA-cleared 7-day Steady Set infusion set could mark a true market shift. The reusable Mobi pump slides into a smaller adhesive patch, offering longer wear time and a design that may bridge the gap for users curious about going tubeless without leaving the Tandem ecosystem.

Beyond the top five, these picks shift away from announcements and first impressions and instead emphasize decision-making, long-term use, and practical, real-world guidance.

This video looks at what users still feel is missing from the Omnipod tubeless pump design, from physical controls to expanded CGM compatibility. It highlights the features that consistently rise to the top as priorities for a next-generation Omnipod.

After a month of FreeStyle Libre 3 Plus CGM, we review the setup, comfort, accuracy, the redesigned Libre app, and performance through workouts, showers, and swimming. While also comparing accuracy to the Dexcom G7, explaining the lack of manual calibrations, highlighting pump integrations, and Apple Watch support.

This video explores what it’s really like to switch from a tubeless pump to a tubed system, using the move from Omnipod to Tandem Mobi as a real-world example. It breaks down the unexpected challenges, day-to-day wearability, and key pros and cons of each option to help anyone weighing tubeless versus tubed pumps decide what might fit their lifestyle best.

This review unpacks the Tandem Mobi experience after using it for over two months. We weigh its size, Control-IQ+ automation, and how core features fit into daily life compared with years on Omnipod. It also digs into practical realities—adhesive patches, charging habits, app quirks, and alert fatigue.

This walkthrough focuses on the basics of a Tandem Mobi site change, from cartridge fill to infusion set connection. It’s designed as clear, practical guidance for new and prospective users.
