If you're on Android, try going to the Google Play Store and searching for "phrase express"... There's doesn't seem to be an Android version of Phrase Express itself, but a search throws up several other things that claim to be similar. I haven't tried them. If you just want boiler-plate text, without expansion, try Clipper/Clipper Plus by rojekti. It's a clipboard manager that can save permanent clips in folders. So can ArsClip Mini.
