Verdict
The clearest difference is ads: FluentPath at none against SonLerni's shown. FluentPath also leads on ratings volume (12 vs 2). SonLerni's advantage is review sentiment (100% vs 83%) and rating (5.0 vs 4.8). On price, update cadence, 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. FluentPath sells 4 in-app purchases, starting at $14.99 per month and SonLerni sells 1 in-app purchase, starting at $59.99 per year. Whichever you choose, the download price is not the number that matters.
SonLerni holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: FluentPath has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 83% of FluentPath's written reviews are positive against 100% of SonLerni's.
Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 19, 2026 and September 30, 2026 respectively.
