Language Islands gets you speaking — with the method language pros use: collect the sentences that matter to you and group them into small, themed islands. This isn't another textbook drilling you on fruit, colors, and "the apple is red." You bring the words from your real life — moving abroad, your partner's family, a trip, a new job, a language exam — and the translation and native-quality pronunciation appear in seconds. Listen. Repeat. Actively recall. That's how a language sticks where it counts: in real conversation. Learn to speak Spanish, French, Italian, German, Turkish, Portuguese, Dutch and more — from English, at your own pace. Build your own phrasebook, hear every sentence spoken by a natural voice, and practice out loud in short daily sessions. Made for real reasons to speak: • Moving to or living in another country • Understanding your partner's or in-laws' language • Getting ready for a trip • A new job, client, or work meetings • A speaking exam or school trip • Reviving a language you learned years ago No vocab drills. No endless word lists. Just your sentences, your islands, your pace. Start talking.

Verdict
The clearest difference is rating: SonLerni at 5.0 against Language Islands's 4.0. SonLerni also leads on update cadence (weekly vs every 5 weeks) and ratings volume (10 vs 1). Language Islands's advantage is ads (none vs shown). 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
Both are free to download. SonLerni sells 1 in-app purchase, starting at $59.99 per year and Language Islands sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
SonLerni holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: SonLerni has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
SonLerni ships an update weekly, Language Islands every 5 weeks. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
