1. ili is Wi-Fi free
Many other translation apps require a Wi-Fi connection and in order for you to use it offline, you'd need enough memory on your phone to download each language. ili on the other hand, is Wi-Fi free and can be used instantly.
2. ili's design is optimized for communication.
Since ili uses directional microphones, it only catches your voice. Most smartphones catch noise from other surroundings which may cause errors.
Using a smartphone
ili speaks to others directly
ili has a speaker facing towards the person you're communicating to. This makes it easier for them to hear. Smartphones on the other hand have speakers opposite of the person you're talking to.
