Verdict

The call

The clearest difference is ads: ilu at none against Boo!'s shown. ilu also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (2.1K vs 201). Boo!'s advantage is review sentiment (96% vs 69%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. ilu sells 9 one-off in-app purchases and Boo! sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for ilu against 4.8 for Boo!.

Written reviews are what separate them: 69% of ilu's written reviews are positive against 96% of Boo!'s.

UpkeepUpdate frequency

ilu ships an update every 3 weeks, Boo! every 5 months. The most recent releases landed on November 3, 2026 and November 2, 2026 respectively.
