Charged automatically checks your sensor and device batteries after every ride or run, and alerts you when one's running low. Connect your Garmin Connect, Wahoo Fitness, or Intervals.icu account once -- then every activity you complete gets scanned in the background for paired sensors with low batteries, and you get a heads-up before it becomes a problem during your next workout. At-a-glance dashboard. Open Charged anytime to see the latest battery level of every sensor you've used — heart rate straps, power meters, radar and tail lights, speed and cadence sensors, even electronic shifting including Shimano Di2 and SRAM AXS. Stop guessing. A lot of us swap batteries too early, tossing coin cells with plenty of life left. Charged shows where each sensor stands, so you replace batteries when they actually need it. Connect once, then ride or run like you always do and let Charged watch your gear in the background. And if you want an instant read, the built-in Bluetooth Check feature scans your sensors on the spot. ## Key features - Automatic sensor battery checks - Low battery alerts - Connects with Garmin Connect, Wahoo Fitness, Intervals.icu - Dashboard of sensor battery levels - Supports various sensors (HR straps, power meters, lights, etc.) - Bluetooth sensor scan ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/charged-sensor-battery-alerts/id6762291041/reviews.md ### 5/5 — Very Useful Tool *2026-08-14* The app is super useful. I love the interface, post ride pop up on my phone, and widget which all make checking battery life so simple. Especially for shifters, I always forget how to pull up battery life on my garmin and the Etube app always disconnects. Charged solves this issue has been super helpful. ### 5/5 — Useful and Fun! *2026-08-14* What a nice user experience and to be able to see all my batteries, for multiple bikes, in one place is great! Keep up the great work and looking forward to updates and additions! ### 5/5 — Great User Interface! *2026-08-02* I just downloaded this app and am very happy with it! The screen and menus are straightforward and the sample screen before connecting your sensors is nice to know what to expect :) ## Frequently asked questions about Charged ### What devices does Charged support?
