Lingle
Lingle's pitch is a live-feeling voice tutor rather than a text chatbot, and the free first lesson is a real way to judge that before paying. With only two people building it and a handful of supported languages, it is a narrower bet than the language-app incumbents.
Pros
- Real-time voice conversation rather than typed chat
- Session memory carries goals and mistakes across lessons
- One full free lesson before any payment or signup
Cons
- Only a two-person team behind ongoing development and support
- No published detail on which platforms beyond the browser are supported
- Language list is narrower than large incumbents like Duolingo
