Verdict

The call

The clearest difference is rating: Gravity at 4.1 against Meridia Languages's 3.0. Gravity also leads on ratings volume (39 vs 3). Meridia Languages's advantage is review sentiment (100% vs 69%) and update cadence (every 3 days vs every 9 days). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Meridia Languages sells 2 in-app purchases, starting at $9.99 per month and Gravity sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Gravity holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: Gravity has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Meridia Languages's written reviews are positive against 69% of Gravity's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Meridia Languages ships an update every 3 days, Gravity every 9 days. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
