Charged: Sensor Battery Alerts

Works with Di2, AXS and more

Free · Designed for iPad. Not verified for macOS.

Charged automatically checks your sensor and device batteries after every ride or run, and alerts you when they run low: heart rate straps, power meters, Shimano Di2, SRAM AXS, radar and more. Link your Garmin Connect, Wahoo Fitness, or Intervals.icu account once, and every activity you sync gets scanned for paired sensors running low. You get a heads-up before your next workout. At-a-glance dashboard. Open Charged anytime to see tracked battery levels, with support for over 100 models from more than 35 brands, including speed and cadence sensors, tail lights, and the bike computers and watches you record with. And, the built-in Check Sensor Batteries scan reads your Bluetooth sensors directly, anytime you want an instant read. Stop guessing. A lot of us swap batteries too early, tossing coin cells with plenty of life left. Charged shows the real level on each sensor, so you replace batteries when they actually need it.
