# Lost World vs Ejen Ali

The clearest difference is rating: Ejen Ali at 4.4 against Lost World's 3.5. Ejen Ali also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 36 months). Lost World's advantage is in-app purchases (none vs 10) and review sentiment (77% vs 51%). On price, ratings volume, monetization model and device support there is nothing between them.

Both are free to download. Ejen Ali sells 10 one-off in-app purchases. Lost World asks for nothing beyond the download.

Ejen Ali holds the better App Store score, 4.4 against 3.5. Both are backed by a comparable volume of ratings — 91 and 136 respectively. Written reviews complicate that: 77% of Lost World's written reviews are positive against 51% of Ejen Ali's, so the app with the better star average is not the one people write more warmly about.
