Customize a compact monitoring panel and use the floating window to follow device activity while working in another app. PRIVATE BY DESIGN No account, advertising or analytics SDKs. Measurements and history stay on your device. The optional network latency probe is off by default; when enabled, it opens a TCP connection to captive.apple.com without uploading measurements. Available readings depend on the device and iOS permissions. Detailed process lists, battery health and cycle count, fan speeds and hardware temperature sensors are not exposed on iOS. Unavailable readings are explicitly marked. Widget refresh timing is controlled by iOS.

Verdict
The clearest difference is in-app purchases: DeviceBeat at none against Smart Calculator's 1. DeviceBeat also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
