# TrashOut vs CDL Prep

The clearest difference is rating: CDL Prep at 4.7 against TrashOut's 3.8. CDL Prep also leads on ratings volume (6.7K vs 6) and review sentiment (81% vs 67%). TrashOut's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CDL Prep holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: CDL Prep has 6.7K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 67% of TrashOut's written reviews are positive against 81% of CDL Prep's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 2, 2026 and October 18, 2026 respectively.
