Rob Pugh, writing on Jetpack’s weblog:
Announcing the new Jetpack mobile app, now available for iOS and Android — hooray! This robust app brings all of your favorite essential Jetpack features to your mobile device. Receive important notifications, keep tabs on site activity, restore a backup if necessary, scan for malware, view valuable site stats, and access other Jetpack features you love, anytime and anywhere.
It’s based on the WordPress Mobile app and designed specifically for Jetpack connected sites. I expect a lot of site owners will appreciate the streamlined feature set.
