Speaking practice whenever you have a minute, for learners past the basics who know more than they can comfortably say. You may understand the language when you read or listen, but still struggle to find your words in a conversation. Bubblz gives you a private place to use the language you already know before the moment feels high-stakes. Choose a situation, speak or type, get feedback, and try again. This is not another lesson to complete. Bubblz is conversation practice for turning knowledge into something you can actually use. With Bubblz, you can: - Practice real conversations for daily life, work, travel, dating, family, and the situations you want to feel ready for - Speak or type whenever you have time, without coordinating with a tutor or language partner - Get corrections while you practice, so you can catch mistakes and try more natural phrasing - Repeat tricky situations until your next answer comes more easily - Choose guided topics or create a conversation around your own life Bubblz is built for post-beginner through advanced learners, from A2 to C1. Conversations and feedback adapt to your level, so you are not pushed back into beginner lessons when you are ready to use more of the language. Practice English, Spanish, French, German, Italian, Portuguese, Dutch, Japanese, and Korean. Spanish, Portuguese, and English include regional options. Bubblz is not a course for learning a language from scratch. If you are a complete beginner, start with the foundations first. Bubblz is for the point where you know some of the language and need more chances to use it. Try Bubblz free and practice the conversations that matter to you. To access the app's features, you need a subscription: monthly or annual. Your Apple Account will be charged upon purchase confirmation or at the end of a free trial. Subscriptions renew automatically unless auto-renewal is turned off at least 24 hours before the current period ends. Within 24 hours before renewal, your Apple Account will be charged at the same rate unless you modify your subscription in Apple Account Settings. You can manage or cancel your subscription at any time in Apple Account Settings. Canceling a subscription stops access to the app's features at the end of the current billing period.

Verdict

The call

The clearest difference is ads: AI Language Practice at none against Duolingo's shown. AI Language Practice also leads on update cadence (every 3 days vs weekly). Duolingo's advantage is ratings volume (5.5M vs 232) and rating (4.7 vs 4.5). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and AI Language Practice sells 42 in-app purchases, starting at $14.00 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Duolingo holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 232, so its average is the more settled of the two. Written reviews complicate that: 65% of Duolingo's written reviews are positive against 66% of AI Language Practice's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Duolingo ships an update weekly, AI Language Practice every 3 days. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
