# x2VOL_ vs Preptly

The clearest difference is in-app purchases: x2VOL_ at none against Preptly's 15. x2VOL_ also leads on ads (none vs shown) and ratings volume (1.4K vs 247). Preptly's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (28% vs 15%). On price, rating and device support there is nothing between them.

Both are free to download. Preptly sells 11 in-app purchases, starting at $5.99 per 7 days. x2VOL_ asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.2 for x2VOL_ against 4.3 for Preptly. That said, the two scores are not equally well evidenced: x2VOL_ has 1.4K ratings behind it against 247, so its average is the more settled of the two. Written reviews are what separate them: 15% of x2VOL_'s written reviews are positive against 28% of Preptly's.
