Preply

Preply fills a specific niche: the middle ground between structured apps and formal language schools. It's not a Duolingo-style app where you tap through exercises; it's a marketplace where you hire a real human to coach you through conversation. If you're the kind of learner who needs accountability and real dialogue, that's a huge advantage. The flexibility is the big draw—you can book lessons at 7am before work or late evening, reschedule easily, and switch tutors without hassle. The platform's Proven Progress feature gives you a tangible way to see your learning trajectory, which is motivating. Where Preply can bite is in the variance. Because it's a marketplace, you're not getting a standardized curriculum. A great tutor can transform your progress, but a mediocre one can waste your time and money. The vetted rating system helps—300,000+ five-star reviews is real social proof—but you need to invest effort in reading profiles and taking trial lessons. Prices range widely, so on a tight budget you might feel the pinch, especially if you need multiple lessons a week. Compared to alternatives, Preply stands apart from self-paced apps like Babbel or Duolingo by giving you human interaction and personalized pacing. It's closer in spirit to hiring a private tutor or joining a language school, and it's arguably more convenient because everything's online and you control scheduling. But those structured apps can be cheaper and are more consistent if you're a complete beginner who wants a guided path. Preply also handles non-language subjects, like math or Exam prep (IELTS, Business English), so it's broader than a pure language app. For businesses, the corporate language training option is solid—it's a centralized way to offer employees language development without
