The Android basic version is free; its full-version upgrade costs $9.99 as a one-time purchase, with no subscription. Listed upgrade features include unlimited categories, up to 250 phrases per category, backups and restore, colors, symbols, history, multiple conversations, voice recordings and user profiles.
