Verdict
The clearest difference is rating: FastZen at 5.0 against Chloe's 4.5. FastZen also leads on update cadence (every 5 days vs every 6 months). Chloe's advantage is ratings volume (56 vs 9) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Chloe sells 8 in-app purchases, starting at $5.99 per month and FastZen sells 5 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
FastZen holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Chloe has 56 ratings behind it against 9, so its average is the more settled of the two.
Chloe ships an update every 6 months, FastZen every 5 days. The most recent releases landed on October 20, 2026 and October 9, 2026 respectively.
