# Bubblegum vs Ludus

The clearest difference is ratings volume: Bubblegum at 162 against Ludus's 17. Bubblegum also leads on update cadence (every 2 days vs every 5 days). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Bubblegum sells 10 in-app purchases, starting at $5.99 per 7 days and Ludus sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Bubblegum against 5.0 for Ludus. That said, the two scores are not equally well evidenced: Bubblegum has 162 ratings behind it against 17, so its average is the more settled of the two. Written reviews are what separate them: 81% of Bubblegum's written reviews are positive against 87% of Ludus's.

Bubblegum ships an update every 2 days, Ludus every 5 days. The most recent releases landed on October 1, 2026 and September 29, 2026 respectively.
