# Pearlz vs GoTall

The clearest difference is ads: Pearlz at none against GoTall's shown. Pearlz also leads on rating (4.9 vs 4.6). GoTall's advantage is ratings volume (6.8K vs 14). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Pearlz sells 3 in-app purchases, starting at $4.99 per 7 days and GoTall sells 15 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Pearlz holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: GoTall has 6.8K ratings behind it against 14, so its average is the more settled of the two.

Pearlz ships an update every 9 days, GoTall weekly. The most recent releases landed on October 10, 2026 and October 25, 2026 respectively.
