Caveat: requires usage of English language. Useful if you (mostly) think in English. Otherwise, if English is not your native language nor your primary language then I expect this application to be problematic. Has anyone falling under such circumstances tried it? Also, too bad (for the application) that the need to remember phone numbers is no longer high.
