PhraseExpress has streamlined my workflow and productivity for more than a decade. Setting it up is a breeze, and it integrates seamlessly with all my applications. The autocomplete function is saving me countless keystrokes. Kudos to the developers for the intuitive design and robust performance. Strongly recommended. There also is an ios version but I am on Android. A linux version would make it perfect.
