## What is HaiBella?

Learn languages like you were always meant to - by bridging vocabulary review from real-time conversations.

HaiBella is a new way of learning through engaging conversations and vocabulary review tailored to your skill level and mistakes. Chat using as much as you can in your learning language, and feel free to say the rest in your native language. As you chat, get instant vocabulary translations and grammar corrections. Every translated word builds your personal vocabulary list, accelerating your progress with each message and thought.

HaiBella strives to make learning from self-created conversations easier and more effective than any other app. HaiBella’s way of learning is most analogous to how kids learn - you build your vocabulary from speaking instead of from generalized lessons.

We will constantly improve the app and its features for the most effective learning and ease of use. Want to send feedback, have a question, or need help? Please contact our support at haibellahelp@gmail.com!

### 5/5 — Intuitive Language Learning

*2026-01-17*

HaiBella is such a well crafted app, built atop an ironclad learning foundation.

### 5/5 — Such a great way to learn a new language

*2025-12-08*

Recently got this app and have been practising my Spanish. It’s surprisingly really effective than other apps like Duolingo. The learning is more intuitive and effective to form complete sentences instead of just remembering random words. The app also feels great to use, with great functionality to track my progress and plan my learnings.

About to replace Duolingo with this app, amazing work!

**Developer response:** Thank you for the review! Vamos!

### 5/5 — Best language learning app out there

*2025-10-26*

So helpful 10/10 recommend

**Developer response:** Thank you for the review!

### 5/5 — Very Good Learning App

*2025-10-19*

I’ve really liked using this app to practice my Chinese. I’m not fluent so it’s great to see corrections for words I don’t know. Would highly recommend!

**Developer response:** Thank you! Good luck on your Chinese journey!

### 5/5 — Feels natural and fun

*2025-10-18*

So smooth and effective! I’m learning faster just by chatting naturally.

**Developer response:** Thank you for the review!

### 5/5 — Great for Spanish

*2025-10-18*

I love this app! I’ve tried Duolingo and Babbel but I like using this app for actual conversational practice. It’s really fun and nice to get immediate feedback!

**Developer response:** Thank you for the review! Hope you continue to improve your language skills!

### 5/5 — Best language learning App

*2025-10-18*

I started using it a few days ago and it’s the best. Super easy to use and also the language options are very good as well. Having both man and female voices is also very helpful, along side the rate of speech. That was super helpful because I can slow it down and hear the word/sentence clearly. 

It’s also really easy to use, it’s as simple as just typing the word in your language and it’ll translate to your targeted language right away. Not only is it good for practice vocabulary, pronunciation, listening, but also grammar. If you want to practice more vocabulary, you can do that. If you want to practice simple sentences, just as easy. As for vocabulary, you can also save the word to your note cards and come back to review them. 

Setting the difficulty level is also very helpful, because everyone learns at a different rate and you can choose how hard or how fast you want to take it to the next level. 

Overall, only good things and I can’t wait for future updates as it’ll only get better, and the creator takes feedback really seriously to improve user experience.

**Developer response:** Wow! Thank you so much for the detailed review! If you have any more feedback please feel free to reach out

### 5/5 — Good practice!

*2025-10-17*

This app makes it easy to both learn and practice vocabulary and conversations in multiple languages. I use it for both Korean and Russian, and it’s great for both. I really like how it suggests translations for words that you don’t know. That makes it really easy to learn new words without losing the flow of practicing your conversation skills. I feel like that made me more confident in my ability to speak Korean and has helped me improve my vocabulary in Russian. Absolutely recommend this app!!!!

**Developer response:** Thank you so much for the review! Hope your Russian and Korean skills continue to improve using the app!

### 5/5 — Amazing app

**Developer response:** Thank you for the kind words and review!
