# ZenClock vs Fullscreen Clock

The clearest difference is rating: Fullscreen Clock at 4.7 against ZenClock's 4.0. Fullscreen Clock also leads on update cadence (every 9 days vs every 3 months) and review sentiment (76% vs 50%). ZenClock's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. ZenClock sells 2 in-app purchases, starting at $1.99 per month and Fullscreen Clock sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
