Lingbe

Lingbe is a voice-call app that matches you with native speakers for immediate conversation practice. Native speakers earn currency by taking calls, creating economic incentive for quality instruction. Calls happen synchronously so you get live feedback on pronunciation and grammar.

It works well if you want on-demand practice without booking tutors in advance. The speaker-compensation model attracts committed natives rather than casual volunteers. The main trade-off is cost (you pay per minute) and less structured pedagogy than tutoring services, so it suits learners comfortable with free-flowing conversation.
