The new SpyBuster iOS app scans your iPhone for other apps that may be surreptitiously sending your data to Russia or Belarus.

The privacy-oriented app comes from Ukraine-based developer MacPaw, which released a version of SpyBuster for macOS in the spring of 2021, not long after Russia invaded Ukraine.

Ukrainians have turned to Apple’s Find My device-tracking technology to follow Russian troop movements. After Russian soldiers stole Apple gear during the invasion, the devices’ Ukrainian owners can see and report on where the troops toting the gadgets are going in real time, including a recent retreat into Belarus.
