  • is great
  • is the defacto standard for this kind of app
  • is inexpensive ($4 MSRP, occasionally $1 on sale)

      • this a personal quirk..
        • I prefer to not add Google account(s) to most of my Android devices

        • uses Google's in-app purchase to upgrade
      • Lite
        • uses an unlock code to upgrade

      • Pro
        • $4 MSRP
  • cons:
    • size of APK is over 25MB
    • requires a lot of permissions
    • most buttons/features are crippled
      • open a prompt to purchase pro license
