Verdict
The clearest difference is review sentiment: Learn Na'vi at 84% against Kalam's 33%. Learn Na'vi also leads on in-app purchases (none vs 19). Kalam's advantage is update cadence (every 10 days vs every 38 months) and rating (4.7 vs 4.4). On price, ads, device support and iOS requirement 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. Kalam sells 16 in-app purchases, starting at $4.99 per 7 days. Learn Na'vi asks for nothing beyond the download.
Kalam holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Kalam has 6.8K ratings behind it against 123, so its average is the more settled of the two. Written reviews complicate that: 84% of Learn Na'vi's written reviews are positive against 33% of Kalam's, so the app with the better star average is not the one people write more warmly about.
Learn Na'vi ships an update every 38 months, Kalam every 10 days. The most recent releases landed on October 23, 2026 and October 28, 2026 respectively.
