This is the ultimate heavyweight matchup in the IPTV world. Smarters Pro has longevity, but TiviMate is the rising king of Android TV.
TiviMate (The Premium Choice)
TiviMate offers incredible multi-screen viewing, flawless EPG integration, and incredibly fast channel switching. However, the premium version costs money and it only works on Android devices.
Smarters Pro (The Universal Choice)
Smarters Pro is free, features a great dedicated VOD UI, and works on absolutely everything (iOS, Android, Web, PC, LG, Samsung). It wins on raw compatibility.
